Every man who has done home renovations knows that you can lay tiles, install doors, or paint the ceiling yourself and save a decent amount of money on this, rather than giving it to workers as payment.

You may not be able to install a double-glazed window alone, but with slopes things are much simpler. If you do the math, your savings will be about 25%, which is quite a lot. Slopes are a necessary installation element after installing new windows. Even with professional work traces of damage to the window opening remain, and they must be repaired to maintain an aesthetically pleasing appearance. The best season for installing them is summer, since installation work in most cases must be carried out from the street side.

What is the best material to make window slopes from?

Using plaster

The cheapest option to get rid of the untidy and sloppy appearance of windows is plaster. It should be immediately noted that it is best to use this method if you have undertaken a thorough renovation of the apartment and have not yet hung wallpaper in the room. Otherwise, traces of plaster or putty will remain on the wallpaper and you will have to re-glue it. Think over this moment in advance, save yourself from unnecessary work.

In choise plastering materials important depends on whether the window slopes will be installed outside or inside. If the humidity in your home exceeds the norm of 30-60% (use a hygrometer to measure this indicator), then it is best for you to use cement base or special plaster for facades (sold in any construction stores). Use gypsum, cement or lime-gypsum base, if you install slopes from the inside.

If you use gypsum plaster, then you can do without reinforcement of the upper slope. If you are using another poorly adhering base, it is better to do it on galvanized mesh, this way you will increase the likelihood that the applied layers will adhere tightly immediately after application.

When applying, use a small spatula. When aligning layers, use the trapezoid rule.

It is important to know

Plaster is not a durable material. Over time, traces of cracks and destruction appear on it, both on the top layer and in the internal ones. Therefore, in a couple of years you will need restoration again.

Tips for finishing slopes with plaster

Pre-protect the window frame from contamination by covering it with some material
Nail a couple of planks with different sides to navigate them and apply the finished mixture evenly.
Prepare the plaster according to the directions and recommendations on the package. Use a bucket partially filled with water room temperature, and a special attachment on the drill for mixing to obtain a homogeneous mass.
Thoroughly clean the window surface from traces of dirt and level the rough surface.
Apply the plaster in several layers, each of which must first be left until completely dry. In this regard, the finishing time varies from 2 to 3 days.
The last movements should go in the direction of the light: from the window into the interior of the room.

Using drywall

This method is faster and less complicated than the previous one.

All work consists of several stages that follow one after another in sequence:

installation of the frame;
laying drywall;
priming before putty;
putty;
priming before painting;
painting.

At its core, this material is gypsum, which is enclosed on both sides between cardboard sheets.

How to make a plasterboard slope yourself:

Take the profile corner and cut it into pieces according to the width and height of the window. Then form a rectangle from these beams and attach it along the edge of the window profile using the required number of euroscrews or self-tapping screws. Don’t worry about the appearance, a little later we will hide them under drywall.
Pre-calculate all the same parameters we need, then cut out the plasterboard blank. Fill part of the slope with insulation (mineral wool is suitable). The inner edge of the panel with the cut corner will be attached close to the corner. We glue the other edge to the slope with special glue. Drywall is divided into three types: waterproof, fireproof and regular. Most the best option when choosing a material, moisture-resistant plasterboard from Knauf or Gyprok is used. When choosing thickness, note that the best range is from 9 to 12 millimeters.
Use sealant and attach a perforated corner at the junction of the side and top panels. Then seal the resulting joint near the window, and thoroughly putty the entire area of the slope. After sanding, coat it with a deep penetration primer and paint it with waterproof PVA paint. Ready!

Use of plastic

The best option today is plastic slopes. Why this particular material? The one-piece design that results from the work fits into any interior and looks most harmonious in comparison with other types of slopes.

Advantages plastic slopes:

Inexpensive cost;
Long service life of the material;
You can choose this color scheme that matches the decor of your room;
Speed of execution installation work. In 3-4 hours you can easily handle the installation;
Plastic is easy to clean, so it is easy to care for and keep clean.

Plastic also has its disadvantages: if you have a hole or crack in it, you will need to completely replace the slope. You should also be aware that this material is very easily affected by temperature, so extremely high thermal exposure must be avoided.

After installing the double-glazed window, the polyurethane foam will harden completely within 36 hours. Once this time has passed, you can safely install window slopes.

When purchasing plastic slopes Special attention focus on thickness. Minimum thickness should be 8 millimeters. Next, correlate and calculate all the parameters of the plastic (length, width, height) based on the data of your window opening.

What we need:

F-stripe equal to the length of the plastic panel.
Plastic panel. The parameters are calculated from the height and latitude of the slopes
Insulation. You can choose any, but mineral wool is most often used.
Small wooden block. We will attach it to the sides and tops of the slopes.
Dowel-nails and self-tapping screws. You will need them in order to attach wooden planks, as well as fix the starting profile
Silicone. To make it look natural, it is best to choose it according to the color of the panels.

This is interesting

Polyvinyl chloride (PVC) is widely used in many industries: construction, toys, furniture, industrial products, etc. Its advantages compared to metal are that it is not subject to corrosion, and compared to wood - to rot. Compared to other materials, it is durable and, if handled with care, can last you for decades.

Calculate the parameters of your window and make blocks of wood of the appropriate length. Once you secure them on each side, use a drill to drill holes into which you will screw the screws.
Go out
Use a pencil to mark future holes into which we will then insert dowel nails. Using a level with two ampoules is the easiest way to level the block.
After marking, we do required holes and insert the plugs of the dowels and secure the block, once again checking that everything is exactly at the spirit level.
Install an F-shaped (shaped like the Latin letter F) profile on the block. To do this, use a sawing object (knife, saw, grinder). Also cut out the profile parts for the side slopes. In order to get straight ends, use a tray for cutting boards, which is called a miter box. We will calculate the length we need using the formula: the length of the plastic slope + the width of the part of the profile that will line the slope + we leave 20-30 mm in reserve. Having measured the length that suits us, we cut what we need.
We measure from the lower profile the length corresponding to the distance from one edge of the slope to the other. From the part that remains with us, we cut off the strips intended for winding this profile. Next, we use a stapler (construction) and attach the strip to the block.
We measure the length of the top strip in exactly the same way as in point 4 and secure it again with construction brackets.
We need to accurately calculate 45 degree angle and cut it off in order to later use it at the junction of vertical and horizontal stripes.
One of the last moments before installing the slopes is the installation of the starting profile. Install it using self-tapping screws to the window profile. Pre-mark to avoid unevenness. With a pencil we draw lines at the angle we need.
Using our drawn line, we again attach the strip to the profile using self-tapping screws and carefully trim the ends. As a result, you should end up with a structure whose joints fit almost perfectly together; you should not have any difficulty in connecting them.
We insulate the empty space between the F-shaped and starting profiles by using mineral wool and also install the panels.
At the end of the work, be sure to go through all the joints and coat them with silicone. In this way, we will kill two birds with one stone: 1) the tightness will not allow air to pass through the holes, 2) the external attractiveness will be preserved and brought into proper shape.

note

If you have never installed a slope before, then for the first time try to find someone among your friends who will help you master this business. This way you will protect yourself as much as possible from failures, and besides, together you will get the job done much faster.

Video “How to install slopes on plastic windows yourself”

If you still decide to take it upon yourself and seal the slopes with plasterboard, plastic or putty, then we advise you to watch this video, in which you can clearly see how to make slopes on a window using improvised means.

After installing the plastic windows, the slopes are installed. Proper implementation of this activity affects the subsequent thermal insulation of the room. But how to finish the slopes for the windows inside? Today there are many materials with which you can professionally finish slopes. Let's look at slopes made of sandwich panels, plasterboard, and PVC.

Read also - slopes on plastic windows with your own hands.

Drywall

Many people have a wrong idea about drywall. They believe that it is a profile structure to which a sheet is attached. At the same time, not many people understand how it can be connected to the window system. Therefore, the question related to how to make slopes on plasterboard windows with your own hands is very relevant for non-professional builders.

Organizational process

As a rule, slopes are installed immediately after changing window systems, so the surface should already be prepared.

If the place where the slopes will be located has not been prepared, then it needs to be processed independently, having first removed the remaining plaster from the surface. After which the walls must be treated with a primer in order to improve adhesion.

Drywall slopes - fastening

If the layer of plaster is dense and difficult to remove, then it does not need to be removed, but only if this does not interfere with installation. And to improve its strength, impregnate the plaster with a layer of primer.

Selecting materials

The operating time is already finished product largely depends on the material that will be chosen.
Since there is a constant temperature difference and high humidity near the window, then it is better to make slopes from moisture-resistant plasterboard.
Primer is an important component that plays an important role in the installation of slopes. It will also prevent the formation of fungus or mold.
The drywall will be attached to the planting gypsum. Therefore, it must withstand temperature changes, which will create warm slopes for plastic windows, and have moisture-resistant characteristics.

Taking measurements

When installing slopes after installing plastic windows, measurements are very important. Let's look at how to take measurements in more detail.

Slopes for plasterboard windows

The first thing you need to do is measure the distance from the edge of the wall to the window.
Then you need to measure the distance from the wall to the middle of the window, which sets the slope angle. Thanks to this we get legs.
Next, you should square the length of each side of the triangle, and then add everything up. The square root is taken from the resulting number. As a result, it will become the value of the width that the future slope should have. The length of the panel is measured with a tape measure.

Remember: it is simply necessary to make such calculations. If this is not done, then the result will be visually crooked openings and uneven windows. And to make accurate and quick calculations, use a calculator, thanks to which you can easily extract Square root without using special formulas.

Installation

Before installing the slopes, markings should be made, which should be equal to the distance from the wall to the window. Then it is applied to the frames on which the slope will be located.

After this, according to the instructions on the packaging, planting plaster is diluted. The mixture is applied with a spatula to the wall in order to obtain 3.4 points of contact between the drywall and the wall.

Next, you can begin installing window slopes made of plasterboard, which includes gluing the sheet using planting plaster. At the same time, the edge near the end of the wall must be held tightly, and the edge located near the window is equal to the markings.

Installation of slopes for plasterboard windows

Remember: when adjusting slopes in the markings, it is better to use a level, thanks to which you can easily monitor the curvature of the surface.

Final works

When the putty dries, paint for the window slopes will come in handy for additional protection.

PVC panels

For those who are still puzzling over how to seal the slopes after installing plastic windows, we can offer another worthy variation - PVC panels.

Installation of PVC slopes is divided into several stages. Let's consider each stage separately.

Surface preparation

After a day has passed after installing the balcony block, you can proceed to installing the slopes. First, remove excess foam that appears between the profiles at the joints and the wall with a stationery knife. Afterwards, the surface must be cleaned of any remaining small debris.

Slopes for PVC windows

Initially, using a tape measure, you should calculate the parameters of the profiles along the visible edge. Moreover, it is necessary to calculate their outer width, and also find out the distance from the top of the window to the bottom. It should be noted that this process can be made easier if you completely remove the frames or at least bend the film back a little.

To install PVC slopes for windows, a U-shaped profile suitable in width is used, it is cut into pieces. For these purposes, use special scissors designed for cutting metal sheets. Then the profile elements are attached at a distance of 20 cm with screws to the outer part of the frame. Identical manipulations should be done with the side and top surfaces.

Installation of sheathing

To assemble the sheathing, wooden slats are used (section 2*4 cm), which are attached to the side and upper corners of the slope. To fix the slats, dowels are used, the distance between which should be approximately 30 cm. If you want the perfect lattice, use a plane; thanks to this tool, you can flawlessly adjust the thickness of the slats. Finally, check their levelness using a building level.

Installation of the upper slope

How to repair slopes after installing plastic windows yourself? First, you should determine the length of the external slope, and then cut an element of the required size from the PVC panel. It is better to work with the material using a jigsaw, but the cutting must be done extremely carefully. Next, the panel is attached to the top profile and sheathing with self-tapping screws.

Installation of side panels

The PVC side profile is mounted in the same way as top bar. The space that appears between the wall and the panel is filled with polyurethane foam. For this purpose, the outside of the product is wetted, and then foam is applied to it. Such work continues until all free space is filled with material. A PVC panel is attached next, and do not forget to ensure their evenness using a level, and also secure them with self-tapping screws. The relationship between slopes and angles is controlled by a tool called a malka.

Slopes for plastic windows

Installation of F-profiles

At this stage, the installation of plastic corners is carried out, during which the product of the required size is cut, and then it is inserted onto the panel along the edges. In those areas where the corners come into contact with the screws, a small cut should be made on the inside of the corner.

Final stage

At the end, the joints are finished, in which a slope sealant or a profile mixture is used suitable color. The composition is applied to the joint cut and then gently pressed. Remains are removed. The sealant will protect the product from dust, moisture, and debris.

Sandwich panels

When installing slopes from sandwich panels, builders use 3 main materials:

foam;
liquid Nails;
wooden beams.

Foam installation is the most easy option. However, in this case it is necessary to purchase sandwich panels that have a rigid frame. This process is done like this:

taking measurements;
cutting the frame strip;
frame assembly;
fixing the frame between the upper slope and the window sill;
cutting panels;
inserting panels into the frame.

Foam

First, 2 side slopes are assembled, and at the end - the upper one. Before blowing the system with foam, you need to measure the slopes with a level, and also install spacers so that the swollen foam cannot move the frame.

Slopes made of sandwich panels

This method can only be implemented if two-layer sandwich panels are used. To improve adhesion, before blowing out the cracks, the wall of the room and the inner plane of the panels should be sprayed with water from a sprayer.

After a day, the foam will harden, then it will need to be trimmed. Next, overlays are put on, which perform a decorative function. Sometimes installers carry out this process immediately, but this is not compatible with technical rules.

Liquid Nails

They will be appropriate only if the walls are in good condition. Thanks to liquid nails, you can avoid using the frame and install it directly on the wall.

This method is suitable for spacious windows, where a lot of plastic will negatively affect their appearance. The process is divided into the following stages:

measurements;
panel trimming;
preliminary fitting;
leveling the surface (plastering, removing old materials);
gluing the panel.

Initially attached external panel, and the side ones adapt to it. But after that there are 2 unresolved problems:

seams in adjacent areas;
open end element.

I seal the seams with a simple putty mixture that matches the color or with silicone, provided that the plastic is white. Today, they are increasingly used for such work acrylic paint, its texture is similar to PVC coated, thanks to which you can create a good appearance.

Slopes made of sandwich panels for windows

The end can be covered with a layer of plaster. And if the windows are located over the entire surface of the wall, then you won’t need to think about what and how to paint the slopes on the windows inside. In this case, the end is painted with white paint, but it should be noted that the sandwich panels must have an identical color. You can also just hang wallpaper.

Wooden blocks

To reduce foam costs during the installation of difficult, damaged slopes, wooden slats are used, which are the basis for attaching the frame. The technology of this process is as follows:

taking measurements;
beam trimming;
assembling a quadrangle to which sandwich panel strips are attached using a stapler;
trimming and subsequent insertion of panels into the base;
foam blowing;
after 24 hours, all excess is removed;
installation of overlays.

Window slopes made from sandwich panels are particularly resistant to mechanical defects. Give preference to 3-layer panels, because 2-layer panels are not rigid enough. However this condition not necessary.

To complete the installation of the front door or windows, you need to finish the slopes. A door or window slope can be made using plaster, drywall, and plastic panels.

The most common option for facing slopes are plastic panels. Since finishing window slopes inside with plastic is universal solution. It should be noted that this building material is used for interior and exterior work.

Advantages of plastic

To cover the slopes of a house, the plaster method was previously used, then plasterboard, which was widely used for cladding. But with the advent of PVC windows, plaster and drywall faded into the background. Since finishing slopes using the plaster method has significant disadvantages. The main disadvantages include:

If you plaster the slopes yourself, it takes a lot of time.
This type of finishing creates a lot of construction waste.
Due to shrinkage and temperature changes, cracks may occur on the surface.
The component elements do not form the required adhesion to the plastic, as a result of which the slopes peel off from the window.

Internal window slopes made of plastic

To properly plaster the window opening, you should use a perforated corner and beacons. The perforated corner is installed on the outer corners of the slope. To do this, you need to cut off a corner of the required size, apply putty to the slopes and press the perforated corner. The plaster beacon is installed vertically along the window frame. To do this, cut the beacon to the required size, apply putty along the box and attach the prepared parts. After 40 minutes, you can plaster the slopes.

A finishing material such as drywall provides the opportunity to make slopes faster and warmer. But even the moisture-resistant version of this material cannot withstand temperature changes and the influence of condensation. PVC window slopes have a more interesting appearance.

Advantages of plastic slopes

But beauty is not their only advantage positive characteristics credited:

The panels are made of the same material as the window frame, hence the window space P The premises acquire a monolithic structure.
It is enough to simply install the insulation. It should be noted that with proper insulation, condensation is impossible.
Installation of plastic panels creates virtually no debris or noise.
This kind of building material can be used externally and internally, since polyvinyl chloride does not emit harmful substances.
Insensitive to moisture.
Duration of use.
Tolerates temperature changes perfectly.
Easy to use.
Construction materials vary in quality pricing policy Therefore, it is available to everyone who plans to install plastic window slopes with their own hands.

The disadvantages of plastic include the impracticability of fragmentary restoration.

Do-it-yourself plastic slopes for windows (video)

Selection of building materials

Before you think about how to make plastic slopes yourself, you need to consider possible variations in materials. There are 2 types of plastic panels:

Decorative.
Sandwich panels.

Decorative slopes can be used:

For the formation of partitions.
As a facing building material for balconies.

Necessary tools for finishing window slopes

For all other purposes, preference should be given to sandwich panels. This kind of material differs in that it has 2 protective layers and a facing layer of insulation. This structure allows you to avoid additional insulation. Key points for selecting panels:

Preference should be given to building materials made from virgin plastic. Since the correct material is chosen, it will not change color, and the composition will not cause damage to health.
It is better to choose a material with a significant plastic cover. Panels with thin PVC sheet covering are not durable. Over time, the plastic peels off the surface.

Finishing window slopes with plastic requires the following materials:

Profile.
Self-tapping screws.
Dowels.
Wooden slats.
Gypsum insulation wool.
Liquid Nails.

Preparatory moments

Removing polyurethane foam residues

To finish the inside of window slopes with plastic in a high-quality manner with your own hands, you need to clean the walls and prepare all the necessary equipment and building materials. To form slopes, the thickness of the plastic strip should be 8 mm. The width and duration of the plastic must correspond to the size of the opening. You should prepare and clean the walls step by step:

Remove excess foam.
The shipping tape must be removed from the window profile.
Seal the internal seams.
The upper reaches and side sections of the hole must be freed from whitewash and leveled with putty.
It is recommended to wipe the prepared area and apply 1-2 layers of primer.

Technologists I formation and installation

After preparing the opening around the circumference, you should glue vapor barrier film. At the combination points, sections of the film should be laid with an excess of 5-7 cm and glued along the seam. The tape must be glued so that the edges do not extend beyond the window frame. After this, you can proceed to the formation of slopes using the following instructions:

We fasten the bars with dowels

Fastening timber material. For these purposes, wooden slats with a thickness of 15 mm and a width of 40 mm are taken. The slats should be trimmed to the width and height of the outer edge of the opening. The slats need to be secured with dowels around the circumference of the opening. If the walls of the hole are wavy, then it is recommended to place wedges under the planks.
Take the necessary measurements carefully. It should be understood that all measurements must be taken from the frame, and not from the edge of the special profile.
Open the slopes. The length and width of the walls of the hole should be correctly measured, and attention should also be paid to the angle of inclination on each side. You should mark the cutting points on the slab and cut out the workpieces. The resulting elements should be attached to the wall and their location and angular fit should be checked.
Special profile fastening. A special profile should be attached along the outer edge of the opening with short screws. When joining the bars together, the special profile should be secured in the corners so that no gaps are formed. Installation of slopes begins with the manufacture of edging. This structural component is made from an F-shaped profile. All manipulations should begin from the top element. The profile must be cut to the size of the external opening and the corners must be filed at 45 degrees. The prepared special profile should be attached to the block so that it can be covered with plastic, but without blocking the groove for fixing the slope.

Installation of plastic slopes

The profile is fixed to the beam with staples. The remaining sections are mounted in a similar way. The prepared slope element must be placed in a special profile, pre-coated with sealant. The resulting gap between the plastic and the wall must be sealed with insulation. It should be noted that the layer insulation material should not be overly massive or have vacuums. The outer edge of the slope must be inserted into the groove of the special profile and pressed to align the panel. Next, you should sew up the side slopes, while carefully distributing the thermal insulation. If the external walls are insulated, then such manipulations with the slopes do not need to be performed. In such a situation, the gaps between the panels and the base of the slopes should be sealed with polyurethane foam.
The final period involves attaching decorative corners, which should be glued with glue. The contact points between the panels must be degreased and all cracks must be sealed. acrylic sealant. Acrylic should be squeezed directly into the gap, rubbed and leveled, and any excess should be removed with a damp cloth. All manipulations should be done on small areas and wipe gently clean. Because while the acrylic has not hardened, it can be removed quite easily. The area of the opening under the window sill is being plastered.

PVC slope cladding

Advice! You can veneer window slopes in another way, which differs significantly from the previous one. This method allows you to cover a window slope using any PVC material. It should be noted that this option is used when the installation seam has a small interval, that is, the distance from the frame to the wall is minimal.

The initial stage should be carried out in stages:

Cleaning.
Elimination of defects.
Applying primer.

Sheathing slopes should adhere to the following rules:

Remove excess foam, making sure that the cut is placed flush with the surface of the frame.
Facing slopes with plastic plates involves treating the surface with a primer. Preference should be given to penetrating formulations with the addition of antiseptic components.
Fixing slats.
An important point is trimming the polyurethane foam. The cutting is done in such a way that a groove is formed for fixing the plastic. Trimming is done in close proximity to the frame to ensure maximum adherence of the material.
Reveal the details.

Window slopes lined with PVC

After the manipulations have been performed, a number of actions should be performed:

Using a jigsaw you need to cut plastic. As a rule, burrs may remain along the edges, which can be removed with sandpaper.
Performing preliminary installation. This manipulation will allow you to determine the presence of defects. If double-sided plastic is used for cladding slopes, then one side needs to be sanded a little, thereby indicating the wrong side of the material. Carrying out such manipulation promotes better adhesion. Since PVC panels are fixed using polyurethane foam.
The prepared elements are placed in the right place. They need to be installed in the prepared groove. Using a level, the structure is leveled.
The outer edge of the part is moved back and foam is poured into spots.
All structural parts are attached to each other using masking tape. Fixation is carried out along the circumference of the structure and at the joining points.

Important! Beginning craftsmen have a question: how long will it take for complete drying? As a rule, it will take a day for thorough drying. After which additional finishing activities are carried out. It should be remembered that external slopes also require attention.

Quite often, siding is used for such purposes. Working with building materials does not cause any particular difficulties due to the characteristics of the material. But if difficulties arise, then on the Runet there are many videos and photos with detailed instructions regarding siding installation. The simplicity of installation work will allow you to do the cladding yourself.

Photo gallery of finished works

The final stage of window opening design is finishing the window slopes inside.

This is not only the aesthetic side and completeness of the interior, but also the replacement of old plaster, which makes the openings more reliable with improved thermal insulation.

If the slopes are made with high quality, their heat and soundproofing properties will only improve. You should not postpone this procedure until later, as this can lead to unpleasant consequences:

Thermal insulation can be damaged as a result of the action of sunlight on construction foam, which is usually used to treat openings;
If the foam layer is not treated, it will draw moisture into itself, thereby destroying the structure during the cold period;
Cracks may appear due to an increase in the volume of foam;
Drying of the polyurethane foam leads to the fact that it begins to crumble and gradually loses its thermal insulation properties.

Slopes can be finished various materials: laminate, wallpaper, wood, parquet boards, cork, decorative plaster. The base should be selected in accordance with the design of the room and the material of the window opening itself.

Light finishing requires the use of light materials, which cannot be said about heavy types of cladding, for example, tiles. Here you should prepare a cement-gypsum base.

Let's look at the most popular options.

Plastering

This method can be called the classic finishing method. It will require the following materials and tools:

Cement;
Sand;
Starting putty;
Finishing putty;
Water;
Primer;
Roller;
Level;
Water-based paint;
Dye;
Sandpaper (fine grain).

Work should begin after 36 hours so that the foam adheres well to the openings.

The window is cleaned of old plaster, paint, wallpaper and dust. A layer of mortar is applied to the walls, then to the slopes from bottom to top. A solution is prepared from sand, cement, water and the first layer of plaster is applied where a large amount of the mixture is required.

Each next layer Place after the first one has completely dried. The thickness of each application should not exceed 7 mm.

Afterwards, the surface is rubbed down with fine-grained sandpaper and you can proceed to painting it with water-based paint, which can have any color using dye, according to your design.

You can also wallpaper it. The good thing about this method is that it is the basis for any type of finishing. But there is also a drawback: the solution made of sand and cement has an unreliable connection with the PVC frame material, which can lead to cracks.

If speak about thermal insulation properties, then they are weak and will ultimately lead to the formation of condensation and mold. To prevent this from happening, it is necessary to additionally install a layer of insulating material.

Drywall

Moisture-resistant material is mainly used when finishing slopes inside, since it is resistant to condensation on the window and is characterized by thermal and heat-insulating resistance.

Sheets of material are attached to a prepared sheathing (metal or wood). The surface should be pre-treated with a solution if there are strong potholes.

Assembling the slope begins with the panel located on top, its edge is coated with glue and inserted into the starting strip. The second end of the drywall should be pressed against the wall. This procedure must also be carried out with the side panels. Here it is mandatory to treat the joints with a neutral sealant.

To extend the life of corners, you can use paint corners.

The last step is to use putty and apply acrylic or oil paint to it.

Decorative rock

Natural stone is used quite rarely. There are reasons for this. First of all, it's heavy. Secondly, it is expensive. Therefore, an excellent analogue is decorative stone. They are used to finish door and window openings, and you can handle this work yourself.

Are being selected decorative slabs 2 cm thick. An area is being prepared for attaching artificial stone (plastering). Notches are made on the surface; for more reliable fastening, glue is added and treated with a primer.

Then, after drying, glue is applied to the slab or wall and the stone is fixed. You can also use liquid nails. The work is carried out using a building level.

Laying is carried out in horizontal rows from bottom to top. If necessary, trim the stone.

Plastic, laminate and parquet boards

The use of plastic is the most common processing option, as it distinctive characteristic is durability (15-20 years).

It is convenient to install it for several reasons:

Work can begin on the same day;
Plastic panels are an additional heat-insulating barrier between the room and the street;
High moisture resistance;
The homogeneity of the material of the glass unit and the slope allows working synchronously during temperature changes;
Does not fade;
Cleans well, does not sweat;
Does not need painting;
Has an attractive appearance.

Technical features of the material allow you to make slopes various forms– bay windows, arched and round.

This finishing method deserves attention, as it looks original. There is one problem with working with laminate boards: they crumble. Therefore, you should decide in advance what to hide corner places joints

Finishing can be started from top to bottom and vice versa. The difference is noticeable only in the direction of the grooves of the lamellas. Fastening is done with self-tapping screws, each subsequent lamella covers the groove of the other, due to which the fastening points remain invisible.

Parquet boards are quite easy to saw, since the base is wood. Laminate or parquet board Can be mounted on drywall.

Finishing the slopes inside and outside should be done simultaneously. Work is carried out at a temperature of 20-25 degrees.

To improve the quality of slopes, they need to be insulated. For an opening finished with plaster, it is better to use paint as the last layer - this will increase its moisture resistance.

The finishing of the window slopes inside may be different, but the developed angle must be maintained so as not to disturb the distribution of light in the room.

Finishing window slopes inside the apartment

When creating their masterpieces, architects attached great importance to windows as the final stage in the formation of an architectural ensemble. Sizes, shapes and functional purpose changed over time and the requirements of architectural fashion.

Architecture improved, and along with it, windows became the dominant decorative motif walls. Having absorbed the variety of styles inherent in a particular era, the windows acquired a laconic appearance and a classic shape. This element of architecture is decorative in nature and surprises with its functionality.

Plastic windows long period prevail over their wooden counterparts. Therefore, finishing the slopes of plastic windows and their installation does not lose its relevance.

Types of materials

More recently, plastering of slopes has been in use. At the same time, the adhesion of plastic and plaster was not very good. Very often, the seams cracked; due to temperature changes, the entire surface of the window cladding cracked. hydro-, heat- and sound insulation was violated. At the same time, plastering is a complex and lengthy process that requires patience and accuracy.

With the help of modern developments, the finishing of window slopes inside is presented in several types, which involves choosing based on the positive aspects of the materials.

Panelit is a cellular panel made of PVC with an internal polystyrene foam filler. It is used at a depth of no more than 25 cm. The joining of this panel with a deeper window opening loses its presentability and also changes color over time. Due to its low weight, finishing the windows inside does not pose much of a hassle. They have increased resistance to mechanical damage.
Adhesive plastic is attached using glue. It has a number of disadvantages: peeling as a result of temperature fluctuations, and condensation forms when freezing.

Sheets of plasterboard as a finish have good thermal insulation, are environmentally friendly, and can be painted in any color. Disadvantages: when high level humidity causes cracking and destruction of the integrity of the plasterboard structure.

Sandwich panels are made of polymer plastic and are the most reliable option for finishing window openings: providing thermal insulation, color preservation, easy to maintain, and durable polymer coating, aesthetic appearance, reliability and durability during operation. At making the right choice insulation, fire-resistant sandwich panels. Sheet plastic is different high quality, excellent thermal insulation, exact color match with the window frame. The disadvantage is the high cost.

With all the diversity, it is worth taking a responsible approach to the choice of materials, taking into account all the listed factors, first how trim window slopes inside .

How to do interior window decoration yourself

In order to finish openings. It is not necessary to resort to the help of qualified specialists. The easiest way, which is completely doable, is to decorate the windows with plastic with your own hands. It is enough to follow the rules and veneer the window opening step by step.

Having bought and prepared everything necessary materials and tools, you can be inspired to start lining the window slopes with plastic.

Preparing for work:

carefully cut off any remaining foam that protrudes;
remove paint and old plaster;
treat with antifungal agent.

Panel cutting:

take accurate measurements;
put markings;
cut at an angle of 45°.

Installation:

secure the cut panels around the entire perimeter of the window opening using small self-tapping screws;
carefully join at the corners;
if there is a slight discrepancy, adjust the design;
maintain a gap of 3 cm between the base of the slope and the plastic structure.

Filling voids:

fill the perimeter between the old and new slopes with installation foam (mineral wool, penoizol);
fill with foam should not be a continuous line, but with small intervals.

F-band installation:

F-profile corners cut at an angle of 45°;
to fix the slats, use choppers made of wood or plastic;
Attach the profile with grooves to the end part of the plastic panel using masking tape.

Finish:

degrease the facing seams at the joints;
fill them with sealant.

As a rule, finishing plastic windows inside takes no more than 3-4 hours, even without experience.

Reasons why you need to trim the windows in your home

The completeness and neatness of the window are created by slopes, both inside the room and from the outside, and also carry a number of functional loads:

external:
- protection against destruction of polyurethane foam,
- prevent moisture from entering,
- thermal insulation,
- maintain sound insulation,
- protection from ultraviolet rays.
- provide reliable grip window frame with an opening.

internal:

decorative component,
protection of waterproofing materials,
eliminates condensation.

If the outside slopes are not finished in time, negative consequences will lead to re-installation of the window unit. These are additional costs of money, time, and effort.

How to finish slopes inside a window

Modern glazing technologies imply careful attention to every detail, so questions about how window sills and slopes are designed also do not go unnoticed by the craftsman. Proper repair These structural elements of the window will provide it with a longer service life and prevent the risk of cold air entering the home. Let's talk further about how the interior window slopes are finished, and what materials need to be used for this.

The need to finish the slopes inside the window

The relevance of finishing window openings indoors and outside the house with sandwich slabs, plaster, etc., as well as the front door decorative stone very high. Internal factors, the action of which can negatively affect the quality of the window itself and its slopes, include:

increased humidity indoors;
the appearance of condensation on the window due to a significant difference in temperature outside the window and inside the house.

External factors that have a destructive effect on the window and its slopes include:

precipitation, wind, sunlight;
sharp changes temperature regime ambient air;
mold, mildew, harmful insects.

Proper finishing of windows and doors with decorative stone allows you to raise the level of resistance of the window structure to the influence of the described factors to the highest possible level. This will ultimately extend the service life of the windows, improve the appearance of window openings in particular, as well as the facade of the house as a whole. You can see a window with high-quality slopes inside the room in the following photo.

Drywall

Most often, the decoration of indoor slopes and entrance doors is done using plasterboard. This is a finishing material with high performance parameters, which allows you to quickly and with a minimum of effort make slopes perfectly smooth and resistant to external influences.

Drywall is lightweight and its installation on vertical surfaces is not particularly difficult. It is beautifully painted in the current color shade. In addition, such materials, when properly treated with antiseptic compounds, can prevent the risk of mold and mildew developing at the joints of slopes and window frames. Window finishing with plasterboard is shown in the following photo.

Material selection

You should not think that you can choose any type of drywall to design slopes in your house. The material should be selected taking into account its operational parameters. And they differ for different types of drywall, which should be taken into account by the master before materials are purchased and window repairs begin.

Absolutely any window is a source of moisture in the form of condensation, which is formed due to the large difference in temperature in the house and outside. As a result, the materials used to repair slopes must certainly be resistant to this factor. This means that you need to select only moisture-resistant plasterboard sheets, on which the presence of condensation will not have a negative impact. Otherwise, the repair will retain its functionality and attractive appearance for only a short period of time. In addition, it is worth using antiseptic compounds to cover the surface of the material, as well as special paint for its finishing.

Finishing the slopes of plastic windows in a house should always begin with taking measurements, for which you will need to stock up on a measuring tape. The final results of the master’s work largely depend on the quality of this stage of work. If the slope does not fit as tightly as possible to the window frame, there will be a risk of developing such negative consequences as:

the appearance of mold and mildew outside and inside the premises;
the appearance of microcracks through which frosty air will begin to penetrate into the house during the cold season. Gradually, without adequate measures to eliminate the problem, the cracks will grow, and with them the costs of heating the premises;
reduction in the service life of the window structure, its rapid wear both in quality and aesthetic terms.

Taking measurements

Installation of slopes

Finishing slopes with plasterboard begins with an analysis of the measurements taken. All window parameters are transferred to plasterboard sheets, from which you need to cut pieces that are ideal for the window opening.

Drywall cutting process

Installation of such canvases can be carried out on the lathing, on the profile, or without them. The choice of technology should be determined by the fact in which state the slopes are. Visually evaluate whether they are processed with high quality, as well as what quality the double-glazed window itself has.

Installation of drywall is carried out using a special adhesive composition if the walls are perfectly even. If not, you will need to first bring them to this state.

Next, you need to attach the strip to the window profile or frame, which will securely fix the drywall on the side of the double-glazed window. Plasterboard panels are installed on top of the planks, carefully treating the resulting voids with sealant. Then the structure will be devoid of cold bridges.

PVC panels

No less popular today is the repair of slopes in the house. PVC panels on the profile and doors with decorative stone, thanks to which the entire structure acquires a solid appearance. Such repairs, as shown in the photo below, have a long service life and retain their properties for a long time.

Plastic panels are selected taking into account the size of the window opening, as well as its technical parameters. Before starting repairs, you will need to prepare the surface of the slopes. Then, PVC parts of the current size are cut out, which will be mounted around the entire perimeter of the window on wooden slats and profiles.

If you want to insulate the house, the space between the wall surface and the panels should be filled with a layer of mineral wool or construction foam. Finishing slopes with PVC panels on a profile is also beneficial due to the fact that PVC materials have a smooth surface and are produced in different color shades, looks harmonious in the interior of a private house. This allows you to save on the final painting of the slopes.

More attractiveness this method lies in the fact that all elements of the window structure (window, slope) acquire the same expansion coefficient, which will ensure they fit tightly together and prevent the risk of cracks forming.

Surface preparation

To install plastic slabs on a slope, you need to carefully prepare the surfaces. To do this, I carefully cut off the excess mounting foam using a utility knife, and the surface itself is cleaned of dirt and dust, coated with an antiseptic, and primed. Next, you will need to install a metal frame made of guide profiles.

A hairdryer can help remove paint from walls.

Installation of the guide profile

Measure the profile along the outer edge using a construction tape, and then its outer width and the distance from the top edge of the window structure to the surface of the window sill. Take a U-shaped profile of the current width, cut it into pieces using metal scissors, according to the window measurements. Next, the sections are screwed at intervals of 20 cm using screws along the outer part of the window frame. The top and side profiles are mounted in the same way.

Metal profile Installation of starting profile

To organize the sheathing, you will need wooden slats with a cross-section of 20x40 mm, which are attached to the far corner of the slope from above and on the sides with dowels in increments of 30 cm. The sheathing must have perfect evenness, for which the thickness is adjusted with a plane wooden slats and check the work at the construction level.

Panel installation

Finishing with plastic plates can be easily done with your own hands. To do this, cut the material with a jigsaw, then fix it on the upper profile and secure it to the sheathing using self-tapping screws.

The side profile is mounted in the same way as the top bar. And the gaps between the window frame and the wall need to be filled with construction foam, for which the surface is first moistened with water. After this, you need to lean the plastic panel against the base and secure it to it with metal screws.

Fastening PVC panels

Installation of F profiles

The F profile is cut and inserted along the edges of the panels. In those areas where the corners come into contact with the fasteners, you will need to make a small cut. At the same time, the slopes of the front door should be decorated with decorative stone, which looks very expensive. At the end of the work, you need to fill the joints with sealant. white, carefully filling the gap with the composition, removing excess volume.

These measures will not only make the window even more attractive, but also protect it from mold, mildew, and rapid wear.

Sandwich panels

Repair of window and front door slopes can be done with sandwich slabs, as shown in the following photo. The window sills and windows are decorated with sandwich slabs, and the door slopes are decorated with decorative stone. Sandwich plate long time retain visual appeal and original operational parameters.

In accordance with all the rules and regulations, repairs of window structural elements allow us to increase the degree of resistance of windows to negative impact negative factors inside and outside the house. The distance between the wall and the sandwich plate must be filled with construction foam, which will act as additional insulation for the structure.

Installation of such plates is not particularly difficult. The sandwich plate is fixed to the base using liquid nails, which will provide the connection with high practicality, density, and durability. Check the angles of the slopes for compliance using a small tool.

Installation of sandwich slabs should be carried out on wooden blocks, which will give the surface of the slope ideal evenness even if there is a deviation of the slope from the vertical. To ensure a neat appearance for the joints of the plates, they need to be treated with silicone.

Plastering

Finishing window slopes outside or inside the house is often done by plastering the surface. But applying this method is only relevant if the slopes are perfectly even. The layer of plaster mass should not exceed 2 cm in thickness, otherwise the slopes will quickly crack and become unusable. This type of finish goes well with the decoration door slopes artificial stone.

Common mistakes

It often happens that the finishing of window slopes inside is carried out in violation of technology, which entails a number of negative consequences. In other words, these structural elements of the window opening acquire low resistance to the effects of negative factors indoors, which entails rapid wear of the slopes. This is why it is so important to identify the most common mistakes made by inexperienced builders when finishing window slopes:

incorrect measurements of the base for installation of sandwich or PVC panels, drywall, etc., which leads to a loose fit of materials to the slopes;
neglect of antiseptic and sealant increases the risk of mold and mildew developing under sandwich panels, drywall and other finishing materials for decorating slopes;
using plaster mixtures often inexperienced craftsmen try to correct base defects by applying an excessively thick layer of finishing. And this is unacceptable, since plaster more than 2 cm thick may crack after drying;
When finishing door slopes with stone, you should not give preference to too cheap material. Decorating even with artificial stone cannot be too cheap, because such savings affect the quality of the finish.

Options for finishing window slopes indoors.

Finishing the slopes gives the window completeness. Many people prefer classic finishing with plaster and drywall. Today, slopes are often made using plastic panels. To determine which window slopes are better, you need to take into account a number of features.

Slope processing methods

After completing the installation work and the foam has completely dried, approximately 5-6 hours later, you can begin finishing the slope. Drywall, plaster, and plastic are used to treat window slopes. Classic finish, plaster, performed in several layers. Before applying plaster, it is necessary to insulate the slopes thermal insulation material. Since during the cold season, when the room is ventilated, a temperature difference occurs, the plaster will quickly crack and fall off. After applying the first coat it takes time as it needs to dry. Then the next layer is applied, and so on.

After the plaster has completely dried, after 24-48 hours, the surface is rubbed down using sandpaper. All work will take 2-3 days. The process is labor-intensive and dusty. Advantages: low cost, naturalness. Disadvantage: when high humidity may crack and crumble. Most suitable for rooms with normal humidity levels: offices, living rooms.

Finishing windows with plasterboard is similar to plaster. Only this method is faster and easier. During operation it behaves the same way. At high humidity acquires gray shade and crumbles. Drywall is a good thermal insulator and quite durable material. Positive qualities: sufficient flexibility, good sound insulation, fire resistance, affordable cost, excellent compatibility with any interior. Moisture-resistant plasterboard is also used to treat windows. Drywall can be attached using self-tapping screws, profiles, and adhesive solutions.

More modern materials for finishing - sandwich panels, plastic panels. Finishing methods with such materials are more common. Window treatment does not require painting or plastering works, there is practically no construction waste during the work.

Advantages when making window slopes with sandwich panels and plastic:

good thermal insulation;
sufficient sound insulation;
do not require painting;
easy care: washable with ordinary soapy water;
quick and easy installation.

The work will take 1-2 hours to complete. Sandwich panels have long term operation, up to 20 years. Plastic slopes are warmer than plastered ones. Absorbs noise from the street, giving the windows an aesthetic and modern look. Plastic slopes are most often used in the dining room, bedroom, and kitchen.

In terms of cost, finishing with sandwich panels is the most expensive method.

The plastic can be selected in color to match the window profile.

Choosing a finishing method

In order to determine which type of finish to choose, you must proceed from following parameters: type of premises, volume and budget of work. Finishing with plastic is the cheapest way, but plastic is not very durable. This type of window finishing is performed in industrial premises or offices.

The most advanced type is sandwich panels. This is a more expensive material, but is well worth the price. The sandwich panel consists of 2 sheets of hard plastic, providing a decent and aesthetic appearance. The material has a hard surface and good impact resistance. Between the sheets there is a layer of polystyrene foam or extruded polystyrene foam.

The advantages are obvious: the slopes do not need to be insulated, since the insulation is in the panel itself. The outer layer is available in both glossy and matte finishes. It should be taken into account that glare appears on glossy surfaces when exposed to sunlight. The thickness of the panels is 10 mm. Fastening is carried out using special profiles.

Slopes treated in this way do not crack, do not delaminate, and are resistant to ultraviolet radiation. Mounted together with the window installation. It is possible to finish wide surfaces. Exclusive option finishing is wood. Wooden slopes are made from valuable wood to order. This finishing is performed mainly for wooden windows. Requires exceptional precision when performing work. They are very fastidious in maintenance, but if you need to emphasize your status and complement the interior, you need to look for a real master.

After you have your windows installed, finishing the slopes becomes a necessary and final step. For new windows, I want to choose the most practical and durable type of finishing for the window opening, namely. And this is not surprising, since correct installation, window profile and the slopes are continuously interconnected. And if any of this component is not performed correctly, then the problem can spread to both the window and the slopes. For example: you have installed quality windows, good manufacturer, but the slopes were made of poor quality. As a result, you get condensation on the windows, blowing and other unpleasant consequences. Therefore, carefully select the material for the slopes and a qualified installation team.

The Teplovik company produces slope finishing using materials such as plastic sandwich panels and plasterboard. If you choose between these completely different types of window treatments, it is difficult to get a definite answer whether plastic or plasterboard slopes are better. Each of these types of slopes has its own advantages.

Plastic slopes made of sandwich panels have the following properties:

Visual similarity with PVC windows - they are often called the logical conclusion of plastic windows, since they consist of a plastic sheet.

Insulation is the only material that has in its structure a layer of extruded polystyrene foam insulation.

They do not require modification - they do not need to be tinted over time; the service life of such slopes can be compared with the service life of plastic windows.

Easy to use - this type of slopes can be washed with any detergent.

Installed only at slope depths up to 500 mm.

Have the following characteristics:

Versatility - this type of slopes is suitable for any windows (wooden, plastic, aluminum).

Installed at any depth of the slope - the only type of slopes that has no size restrictions; it can be installed at any depth of the window opening.

Painting – require updating the paint over time.

They do not have an insulation layer - the plasterboard for the slopes itself is 12 mm wide, but if necessary, the window opening can be insulated.

As you can see, these slopes, completely different in their characteristics, have a number of advantages that play a significant role when choosing a finishing material. But when it comes to plastic windows, it is better to opt for a plastic sandwich panel. were created for PVC windows and, due to related material, are their continuation. Pay attention to the insulation layer, which has thermal insulation characteristics, i.e. does not release heat. If you have wooden windows, then they will fit better. This type of finishing will highlight the beauty of a wooden window frame and give the window opening a classic look. It is worth noting that when correct installation plasterboard slopes can be quite warm, the main thing is to entrust this process to professionals.

So which is better? Plastic slopes or plasterboard? There is no definite answer, but if we consider it from the point of view of ease of installation, warmth and practicality, then of course slopes and plastic sandwich panels are better than slopes made of plasterboard. But if we take into account the slopes custom size and shapes, wooden or laminated window profile, then here the advantages can be given to plasterboard slopes.
