Finishing of internal slopes on the windows. How to trim the slopes inside the window

The foam is destroyed by the sun's rays, and gaps are formed between the frame and the walls. As a result, cold air enters the room, drafts are formed. Also, such an external finish performs a decorative function: it gives an aesthetic appearance... Therefore, external elements must be installed either immediately with the window, or after a short time.

Outside are no less important than inside, and their arrangement and decoration should be approached with no less responsibility.

External slopes of a plastic window affect the durability of the structure, its thermal insulation properties.

Installer plastic windows rarely provides a service for installing this element outside. The only exception is if the client immediately ordered the production of not only internal, but also. At the same time, the cost of the construction of windows and work in general increases significantly. Decorating from other materials by the manufacturer of plastic windows is no longer performed. Therefore, it will have to be done either independently or by hiring a specialist finisher. Of course, the process of installing the external elements of windows requires a certain skill and skill. It is not always possible to carry out work on your own with high quality. Therefore, you should decide whether to save money and do everything yourself or spend a large amount of money, but the work will be done efficiently, in full compliance with the manufacturing technology.

Plastering

For plaster, a special heat and sound insulating plaster mixture is used - perlite, vermiculite, perlite-gypsum.

There are several different ways devices of external slopes of a plastic window from various materials... The most popular slopes are sandwich panels or plaster. Plaster finishing windows belongs to the cheapest type. This is where the advantages of such window elements end, and the disadvantages begin. It is difficult to make them accurately on your own; over time, they begin to collapse, crack. In addition, plastic windows have a weak adhesion to the plaster, which can lead to flaking of the solution. As a result, this requires repairs outside about 2-3 times a year.

For plastering, you will need the following tools:

trowel for applying mortar;
malka;
wood or metal caulk;
plumb line;
dishes for the solution;
wet brush;
hammer;
foam rubber float;
tow;
square for measuring the angle of the bevel.

First, you need to close up the cracks to reduce heat loss. For this, tow is used, which is clogged with caulking. For better isolation the surface can be moistened with plaster mortar.

At the right approach you can "kill two birds with one stone" - not only to plaster, but also to insulate the slopes of the windows.

When plastering, it is necessary to perform with a slight bevel (the angle of dawn of the box), which should be the same everywhere. For their accurate calculation, a square is used.

Before applying the solution, the surface should be cleaned of dirt, moistened with water. And after that, the plaster is applied with a trowel. The surface is leveled first with a bevel, and then with a foam trowel. After that, the boards are removed, the corners are corrected. At this, the slopes are ready. To give an additional decorative and protective effect, the surface is treated with paint and varnish material.

Sandwich paneling

Sandwich panels for external finishing window slopes are two sheets of plastic, between which there is a layer of foamed polyurethane foam.

Sandwich panels for decoration are two sheets of plastic, between which there is a layer of foamed polyurethane foam. This method has a number of advantages: easy to install, durable, resistant to weathering, has high thermal insulation properties, easy to clean, wide choose various colors.

For installation from sandwich panels you will need:

knife for cutting sheets;
U-shaped PVC profile;
self-tapping screws;
drill or screwdriver;
liquid glue.

Installation is carried out as follows. Dirt and dust are removed initially. Then PVC profiles are fixed to the self-tapping screws. They are the starting bars in which the panels are fixed. The profile is flush mounted along the entire perimeter of the window frame.

Mineral wool is currently the most demanded thermal insulation material in the construction market.

Next, the slopes themselves are mounted. First you need from standard sheet with dimensions 3000x1500 mm, cut out panels of the required dimensions. The first step is to secure the upper slope. One end is fixed in the profile, and the other is held on the surface with a liquid nail. The side panels are installed in the same way.

If necessary, the outside structure can be insulated by placing a layer of insulation between the panels. The most commonly used for this is mineral wool. During installation, it should be noted that protective film from panels must be removed only after the end of the process.

PVC plastics are characterized by excellent moisture resistance, vapor barrier, chemical resistance, and foamed plastics additionally have good thermal insulation.

For the manufacture of external window elements, as well as for internal, sheet plastic can be used. This finish is durable, resistant to various influences. It is possible to increase the thermal insulation properties by laying mineral wool between the wall and the plastic. To the disadvantages plastic sheets should be attributed more high cost compared to many other finishes.

For mounting from sheet plastic, you will need the following tools:

U-shaped PVC profile;
plastic profile F-shaped;
wooden lath 10-15 mm thick;
metal scissors or knife;
stapler with staples;
hammer drill or drill;
self-tapping screws.

The process is carried out as follows. First, along the perimeter of the slopes, slats are fixed to the self-tapping screws. Fastening is carried out using a punch or drill. In this case, it is necessary to monitor the even position of the rails. Then the starting profiles are fixed along the perimeter of the plastic window frame. They are also held in place with self-tapping screws.

Next, an F-shaped profile is fixed to the brackets. The slats should fit between the two tails. The joint is finished with such a profile. The next step is to install plastic slopes of the required size. If the structure needs to be insulated, then the insulation should be laid under the sheets. Plastic plates are fixed at one end into a U-shaped profile, and the other into an F-shaped profile. This is where the work ends. If you want to give the window completely perfect view, then the joints of plastic sheets with profiles can be treated with white silicone.

Nothing decorates a window like well-executed slopes. At first glance, decorating window slopes with your own hands is just a solvable task. In fact, this is not the case. Before starting work, it is imperative to study the technology and then skillfully apply it, since the correct slopes are not only a finished view of the window, but also an important technical moment... So, let's take a closer look at what "these slopes are such an animal, and what they eat it with."

Of course, a common man in the street may immediately have a question: "Are they so much needed?" Without interior decoration the process of installing PVC windows is considered incomplete, since the main task of the slopes is to protect the foam filling the gap between the wall and the frame from the influence external factors... This material will serve you for a long time only in the absence of exposure to air and sunlight.

The consequence of the absence of slopes inside or their illiterate installation are:

emergence black mold due to high humidity on the slopes;
drafts in the apartment;
fogging of windows and their rapid wear.

There are several types of materials for interior decoration of windows. We will present them below.

Methods for finishing slopes

Surely, in almost any city in our country you can find firms offering services for installing window slopes inside, but, frankly, this procedure is not cheap. In this regard, significant savings for family budget there will be a choice in favor of do-it-yourself finishing. Decorating the slopes of windows with plastic, although it seems a difficult and overwhelming business, everything goes well in the right hands.

Before the start finishing works a preparatory stage should be carried out: removing dust and old paint (if any) and impregnating the walls with an antiseptic primer.

The surface has been prepared, and now we will consider what types of finishing the window slopes exist:

plastering;
plasterboard finishing;
plastic finishing.

Let's see what the essence of each method is.

Plastering of slopes

The method of finishing internal slopes with plaster was very popular at one time. This option is suitable for execution in brick, monolith and stone houses. For wooden buildings other methods would be more suitable.

In areas where severe frosts in winter are possible, the use of modern heat-insulating plaster will be relevant. This mixture prevents the slopes from freezing.

Stages of doing plastered slopes with your own hands:

application plaster mix on slopes in several layers. Important: next layer spread only after the previous one has completely dried. Plastering lasts one to two weeks;
foaming gaps;
surface primer;
filling and painting of slopes.

Method of finishing slopes using plastering compounds has a number of serious disadvantages, outweighing the positive qualities of the method. These include:

inconvenience and laboriousness of the procedure;
the high cost of the materials used (cheap mixtures eventually lead to the passage of cold air through the window);
the formation of tears due to the difference in the properties of the plaster mixture and the plastic of the window;
fogging of windows due to the lack of the required thermal insulation.

Plus, professional skill is required to do this job correctly.

In connection with the above disadvantages of finishing the slopes with plaster, some experts do not even recommend considering this method as a do-it-yourself finishing option.

Finishing slopes with plasterboard

The use of drywall for windows inside is a transitional option for finishing in terms of quality and cost of work.

There are three options for attaching drywall to the surface of the openings:

metal profile;
adhesive mixtures;
polyurethane foam.

Most often, a metal profile is used, since its installation is simple, and the structure is very durable. They work with foam when the use of the previous options is irrational. For example, there is nowhere to attach a metal profile, or there is no possibility of applying glue to the surface of the opening. Newbies in the decoration of slopes often work with glue mixtures.

Installing drywall slopes with your own hands using metal profile includes:

attachment along the border of the frame of the L-shaped profile (base for drywall);
covering the profile with a sealant;
filling the space between the opening and the slope with stone wool;
gluing drywall;
sealing gaps with sealant;
putty and decoration of slopes (painting, applying decorative plaster or film that imitates various textures).

Among the advantages of drywall slopes are: long service life, smooth and aesthetic appearance, excellent thermal insulation qualities.

The downside of this material is that it is afraid of moisture. In this regard, drywall slopes are not installed in rooms with high humidity.

Decorating slopes with plastic

The use of plastic panels for finishing window openings is quite common, modern method... The use of plastic helps to achieve a perfectly straight surface that is superior in quality to drywall and does not require decorating. Such slopes do not need periodic repairs at all. Easy care includes only cleaning from dust and dirt with a damp cloth.

Consider what materials are available on the market for this method.

Plastic panels

The method of finishing windows is very popular. plastic clapboard... It is attached to the opening with mounting foam, which does not require the use special tools, and this is an absolute plus of the method. But, as in the version with plaster, it will not be easy for a person without special skills to achieve perfect result... The work lead time is about three o'clock for one opening.

PVC panels

PVC panels are a composition of plastic sheets connected by stiffening ribs, in the gap between which there is free space.

Specialized PVC slope systems are now sold in stores. Their parts are purposefully manufactured taking into account the parameters of both conventional and non-standard window openings. Therefore, almost everyone can do window cladding with their own hands using this method. The only drawback of ready-made PVC systems is their high cost.

Sandwich panels

Unlike simple PVC panels, sandwich panels have a structure consisting of three layers of plastic, between two of them there is an insulating material. In the role of insulation, polyurethane foam is often used, which meets all safety and environmental parameters.

Among the advantages of sandwich panels, it can be noted that during their installation there is no need to insulate slopes, because these panels have remarkable thermal insulation properties. But these panels are also imperfect and can delaminate when exposed to humid air.

Decorating window slopes with plastic panels is a popular and versatile method. Such slopes:

you can quickly do it yourself;
under the influence of sunlight, they do not change color and do not deform;
just wash;
resistant to static electricity and other negative factors;
look quite presentable (it is very easy to choose a material that matches the color of the window frame).

Facing slopes PVC panels carried out without unnecessary actions: puttying and painting. They have a good ability to keep out steam.

Resistance of PVC panels material to temperature differences within ± 20 degrees Celsius - another positive quality such slopes.

Consider how the basic steps are followed for facing slopes with plastic panels.

Stages of facing window openings with PVC panels with your own hands

Before proceeding with the very facing of the slopes, it is necessary to clean the surface of debris and remove the protruding sections of the polyurethane foam. Next, the walls must be treated with antifungal agents.

Frame fabrication

All over the border window opening are nailed wooden blocks 0.8-1 cm thick, 2.5-3 cm wide. To secure them, self-tapping screws 9.5 cm are used. The bars are placed in such a way that they do not go beyond the edge of the wall. The bars are fixed vertically, aligning with building level, so that the slopes are completely flat. Note that when choosing bars for the frame, they must pay attention to the quality of the product and material. The wood should be dry and not damaged by pests, and the bars themselves should be even and smooth and without blue discoloration, which is an indicator of the beginning of decay of the material.

PVC panels have sufficient rigidity, which does not allow them to mask small gaps at the junction window frame to the opening. These cracks in the future may be the reason for the appearance of drafts in the apartment. To avoid this, during the facing of the slopes, a heater is laid between the surface of the opening and the panels. As thermal insulation material use: isolon, expanded polystyrene or stone wool... It is important to lay the insulation in such a way that its thickness does not exceed the thickness of the frame bars. Fix it with glue.

With the help of self-tapping screws 4.5 mm, a U-shaped plastic profile is attached along the border of the junction of the window to the wall of the opening. In the future, a PVC panel will be inserted into it. The side elements are fixed directly to the frame. The lower horizontal section of the profile is fixed directly to the surface of the opening, the upper one is fixed with one edge on the bar, and the other edge is inserted into the groove of the vertical profile. In the places of abutment of the sections of the U-shaped frame, the corners are slightly cut off with a knife to make a neat joint.

The F-shaped profile is fixed on the outer border of the window opening in such a way that its wide part is on the front side (the fastening resembles a corner). This element is attached to the wall with liquid nails. The surplus of the F-shaped profile is cut off after joining. Note that this element of the slope structure hides the uneven cut of the wallpaper around the perimeter of the window opening. Fixing the F-shaped profile is carried out only after the PVC panels are inserted into the grooves of the frame (the grooves are partially filled with acrylic sealant beforehand).

Installation of PVC panels

Front installation of PVC panels in the frame measure the length and width of the slope as accurately as possible. If the width of the plastic is greater than the vertically located opening, then the excess part is cut off using a clerical knife. After installing the plastic, the joints are "refined": rubbed with silicone white or with the help of liquid plastic, they are closed with a polyvinyl chloride corner, matching the color of the panels.

So, we reviewed all possible ways interior cladding slopes. By the combination of the advantages and disadvantages, the time of the procedure, the durability of the result, most experts agree that optimal material for finishing window openings with their own hands are PVC panels. But the choice of the appropriate option, no doubt, belongs to the performer. Level to help you!

The fashion for plastic windows is not decreasing. On the contrary, such designs are gradually gaining more and more popularity. However, such an installation is usually accompanied by the need to manufacture window slopes, without which the windows will be blown out, and the room will not delight you with its appearance. As usual, the owners are faced with the question of the choice of materials for the slopes. It must be said that the choice is quite limited, since a natural selection of the most suitable materials for these purposes has already taken place. In the article we will list what you will have to choose from, and also talk about positive aspects and the cons of these materials.

Indoor slope plaster

This is the most common method of finishing interior slopes in the past. This is due to the fact that drywall was not invented before, and no one even heard of plastic. Now some owners decide on such a finish because of its cheapness. But is this method really good?

Indeed, having bought a bag ready solution e.g. white plaster or cement mortar, you can independently, very quickly make more or less acceptable slopes. Then the surfaces are sanded and covered with a white water-based emulsion. What's the catch, then? Why is the fashion for such slopes tending to zero?

The secret is very simple. Any plaster surfaces located on the border of cold and warm air are subject to rapid destruction. They are simultaneously affected by the warmth of the house and the cold of the street. The result is the appearance of small cracks on the surface of the plaster within a year. Then they gradually increase, and the appearance of the slopes irrevocably deteriorates. The owners of the premises have to make annual redecoration of such slopes. Therefore, it is not recommended to use any types of plaster solutions for the manufacture of slopes.

Plasterboard finishing of window slopes

This modern material quite suitable for the manufacture of door or window slopes. Moreover, it is, like plaster, absolutely environmentally friendly. It is not difficult to make slopes from gypsum plasterboard if you study the appropriate recommendations. But if you want it to be really beautiful, invite a specialist. The surface of the drywall is perfectly flat, so the slopes will be very even, unlike plaster. Drywall does not require any cosmetic repairs for 25-30 years. The paint may need to be refreshed as it gets dirty.

Plasterboard is installed on glue or on dowels, plastered, and later, after the surfaces have dried, painted in several layers facade paint... The advantages of GCR are obvious. This is a low cost of the sheets and glue themselves, simplicity and high speed of installation. Suffice it to say that in 1 day you can easily make rough plasterboard slopes in 4-5 rooms and then plaster them. On the second day, the slopes are polished and painted. That's how quickly it all ends. Of the minuses, a large amount of dust can be noted that occurs when cutting and fitting drywall sheets. The work is also wet, as is the plaster, so be prepared for a fair amount of dirt in the room.

Plastic slopes

Contrary to popular belief about the dangers of plastic, we dare to assure you that modern plastic panels intended for indoor use are completely harmless to humans. Do you use a lot of things made of acrylic, silicone, leatherette? Plastic does not emit any toxins or fumes around itself, therefore it is also environmentally friendly. And the fact that it does not allow air to pass through does not bother you. Plastered and painted drywall also does not let it through.

A huge plus of plastic slopes is their practicality. Plastic does not get dirty, does not lose its color, caring for it is extremely simple. Slope installation work is done in record time. Slopes throughout the apartment are usually made in 1 day. This is the most clean way manufacturing of slopes from all of the above.

The only "dirty" moment is stuffing wooden blocks inside the walls from the side of the window or doorway. As a minus, it is worth paying attention to the relatively high cost of such slopes. Consider the cost of the plastic itself, plastic profiles, timber and hardware.

Modern glass finishing implies a careful selection of every detail, so questions about how to properly arrange a window sill and slopes remain relevant for the master. Correct installation such structural parts windows will increase their use time and prevent the risk of cold air entering. You should carefully study how the slopes of plastic windows are finished and what materials to choose.

The need for interior decoration

The interior decoration of plastic windows includes not only a decorative function, but also a protective one. The assembly seam should be carefully protected from external influences so that the window system functions as correctly as possible: the windows do not freeze or fog up, and there is no accumulation of vapors on the slopes.

The mounting layer must also be protected as best as possible from condensation accumulations, sunlight and wind, since because of them the expanded polystyrene begins to deform. You can properly protect such material by installing special metal slopes, as well as platbands on plastic windows for exterior decoration which will give the window a more attractive appearance.

A variety of materials can be used for interior decoration of a window in a residential area. This can be decorative plaster, installation on the slopes of plastic windows, independently creating PVC panels or drywall. The decoration of the internal slopes of the window looks beautiful with the help of a decorative artificial stone... To determine exactly which of these methods is better, you need to consider each of them in more detail.

When renovating a house, you cannot do without the use of high-quality finishing materials. Most often, it is interior decorative plaster that is used to seal the walls. Such material helps to create characteristic slopes on the windows, making them unusual and graceful.

Decorative plaster includes fillers of different fractions and origins - this may include natural wood fibers or stone chips with artificial granules different sizes. Decorative plaster it is used as a finishing layer, thereby creating a special textured surface or an expressive drawing, as exemplified by Venetian plaster.

Decorative plaster used for finishing the slopes inside with your own hands has the following characteristics:

The main types of coverage

Decorative types of plasters are divided into groups according to their main substance in the composition and type of filler. They can be textured, structural and Venetian.

Textured plaster has a special pattern that the consumer knows in advance.
Structural plaster creates a simpler relief compared to texture, but its pattern becomes unpredictable.
Venetian plaster includes several layers at once, as a result of which the surface becomes smooth and acquires a characteristic pattern.

Most often, the decor of the slopes of the window opening inside the premises is performed using drywall. Such finishing material has high parameters that help to quickly and easily create slopes with a completely smooth surface and resistance to environmental influences.

Drywall is lightweight, its installation on a vertical surface is not particularly difficult. It quickly turns into desired color... In addition, such materials, when properly treated with antiseptic agents, help to protect the surface from the appearance of mold and mildew at the junction of the window frame and slopes.

Selection of materials for work

You don't have to think that to create beautiful slope design you can use any kind of drywall. The material must be selected taking into account the parameters of its operation. All drywall materials have such a different indicator that the master himself must take into account before buying all the necessary materials and starting to repair the window structure.

Any window is a source of moisture and condensation, which occurs due to the large difference between the temperature indicator in the house and outside. As a result of this, the material with which the slope will be repaired should not be afraid of moisture. Otherwise, the finishing surface will retain its appearance and basic functionality only for a certain period of time. In addition, at the end of the work, you need to use antiseptic compositions to cover the material, as well as special paint for coloring.

Taking measurements of the window

Each renovation work begins with measuring the structure, for which we need a special measuring tape. The final result will largely depend on the quality of measurements. If the slope does not fit snugly against the window frame, then the following problems may arise:

the development of mold, mildew both outside and inside the room;
the appearance of small cracks through which, in cold weather, cold air will penetrate into the house. Over time, without eliminating the problem, the crack will become more and more, which will increase the cost of heating the house;
there is a reduction in the operating time of the window, it wears out quickly and becomes of poor quality and unaesthetic.

Installation principle

The finishing of the slopes will begin with measurements. All window parameters must be transferred to gypsum plasterboard, from which a piece suitable for the window opening is then cut out. Installation of the canvas can take place on a crate, profile or without them. You need to choose an installation method based on the condition of the slopes themselves. It is necessary to assess how well the slopes are processed, as well as how the glass unit looks.

Installation of drywall should take place on a special adhesive, if the walls are perfectly flat. If not, then you need to bring them to good condition in advance and level their surface.

After that, you need to fix the bar to the window profile or frame, which can hold the drywall well from the side of the glass unit. Installed on top of the plank plasterboard panel, all voids are qualitatively treated with a special sealant. It is this design that will prevent frosty air from entering the premises.

PVC panels

Today, slopes are also often processed using PVC panels and doors with decorative stone, with the help of which the opening takes on a beautiful and whole look. This window finish is used long time while maintaining their initial properties.

Plastic panels must be selected, taking into account the indicator of the window opening, as well as its technical features. Before you start finishing work, you must first prepare the surface of the slopes well. After that, individual pieces of PVC material of the desired size are cut out. They will be installed throughout the perimeter of the window on the profile and wooden slats.

At special desire it will be possible to insulate the house, for this the free space between the wall surface and the panel should be filled with a layer of mineral wool or construction foam... The decoration of the slopes with PVC panels on the profile is good because the PVC materials at the same time have a smooth surface, they can be different colors, look good in the interior of the house. This helps to significantly save on the final coating of the slope.

Also, the attractiveness of this method lies in the fact that all structural details (slope and window) become the same in terms of expansion. This results in a tighter fit and eliminates the risk of crevices.

Opening preparation stage

For the installation of plastic plates on a slope, it is necessary to prepare well main surface... To do this, all unnecessary polyurethane foam is eliminated, it is carefully cut off with a clerical knife, and the surface itself is cleaned of dust, dirt, covered with an antiseptic and carefully primed. This is followed by the installation of the metal frame from the guide profile.

Fastening the guide profile

To begin with, the profile along the outer edge is measured using a building tape measure, and after that the outer width and total distance from the upper edge of the window structure to the window sill. Further, we take П shaped profile the desired width, cut into several pieces using special scissors for metal according to the measurement. After that, the pieces of the part are screwed with a total gap of 20 centimeters using screws along the outer part of the window. The fastening of the top and side profiles takes place in the same way.

Carrying out the lathing

To create a high-quality cladding, you need to use wooden slats with a total cross section of 20 * 20 millimeters, which are mounted on the far corner of the slope from above, as well as from the sides with dowels with a step of 30 centimeters. The lathing must be completely flat, for this, using a planer, the thickness of the wooden slats is equal and its indicator is checked using a building level.

Panel mount

Decorating plastic slopes can be done independently and at home. To do this, you need to cut the material with a jigsaw, then fix it on the upper level using special screws.

The side profile is mounted in the same way as top bar... Free space between window frame, as well as the wall should be filled with special foam, for which the frame is pre-moistened with water. After, the plastic panel is applied to the very base and fixed with metal screws.

F-profile fixing

The F profile is trimmed and then inserted along the edges of the main panel. In the place where the corners are in contact with the fastening elements, you need to make a small incision. In this case, the slopes front door need to issue with decorative stone that will look more expensive. At the end of the work, all joints should be filled with a white-colored sealant, and also carefully fill the gap with the composition, thereby eliminating excess volume.

Features of sandwich panels

Also, work with slopes can be carried out using sandwich plates. The window sills and the window are decorated with sandwich plates, and the door slope - with a special small stone. Sandwich boards keep their original beautiful appearance for a long time.

According to the rules for carrying out the repair of a structural element, it is possible to increase the indicator of window resistance to negative impact factors both inside and outside the house. The distance between the wall and the sandwich board should be filled with construction foam, which will be used as a heater for the window structure.

The installation of plastic windows assumes that the installation opening will be exposed to a certain effect. This will lead to the appearance of numerous defects: cracks and holes from fallen plaster, exposure of the base of the walls, protruding excess foam. The best option in order to remedy this situation, it is considered - the manufacture of slopes from plastic. This material is ideal for such work. But the most important thing is that all work can be done independently, which significantly saves the family budget.

Decorating window slopes inside with plastic is one-stop solution, which is now becoming more and more popular. This material is used for indoor and outdoor work. The fact is that such a product has excellent specifications consisting of the following:

Easy to install. If you compare the process of surface cladding with other options, then its advantages will immediately become noticeable. Decorating windows with your own hands does not require special skills, the main thing is to understand the basic principle and follow the rules.
Durability. Indeed, this material has an excellent service life. If the installation is done correctly, then the plastic slopes will serve long years... The only thing that can happen is that this coverage will get bored.
Easy to care for. Modern options material does not require special conditions for themselves. They are sufficiently resistant to any detergents, do not absorb odors and dirt. Of course, this does not mean that strong chemicals can be used for washing. Everything has its own measure.
No impact from moisture. Decorating slopes with plastic avoids destruction. The fact is that metal-plastic windows often cause condensation. This leads to the fact that gypsum or plaster options quickly become unusable.
Availability. The material differs in price, which will be affordable for everyone who wants to install it.

Plastic panels for slopes have good technical characteristics

Of course, if you set a goal, then you can find some disadvantages of such a product, but they are completely leveled against the background of the advantages.

Which material should you choose?

Before you ask yourself the dilemma of how to make slopes on plastic windows, you need to consider the types of material that are used for such work. It is customary to distinguish two main types used for installation:

Installation of slopes

Regardless of what material is chosen, a standard set of tools and consumables is used for work. You may need:

Start profile.
Wooden bar.
Internal and external plastic corners, platbands.
Insulation.
Waterproofing tape and sealant, polyurethane foam.
Spatula and dry putty.
Capacity.
Electric jigsaw.
Screwdriver and level.
Construction glue gun and "liquid nails", self-tapping screws.

Standard set tools for mounting slopes

Accurate re-enumeration additional elements depends on how the plastic slopes will be installed on the windows.

Option number 1

This option is used when the assembly seam is a small gap. That is, the distance from the frame to the adjacent wall is minimal. This creates some difficulty, because it is necessary to take into account the location of the hinges and opening doors. Therefore, work is carried out according to specific instructions:

Before installing plastic slopes, you should cut off excess foam. This is done with a construction or clerical knife. It is necessary to eliminate a common mistake - removing too much foam, because the cut must be flush with the surface of the frame. Otherwise, the existing balance will be upset, which will require additional efforts.
Trimming excess polyurethane foam
Areas of plaster that are prone to falling off are removed. There is no need to remove the entire layer, just the damaged parts. The surface is cleaned of dust and dirt residues.
Deleting damaged areas plasters
Do-it-yourself installation of plastic slopes assumes that all areas will be treated with a special primer. It is better to choose penetrating formulations that contain antiseptic components.
Treatment of window slopes with a penetrating primer
On a note! To prevent the formation of mold and mildew, special substances are used. This procedure should not be neglected, because such problems are the scourge of plastic windows.
Next, a wooden lath is fixed. It must be installed along the outer perimeter of the opening. Dowels and self-tapping screws are used for fastening. It is better to make a structure that will be installed on the vertical and horizontal (upper) sections, so that the posts do not come into contact with the upper bar.
Now a very important procedure is underway: you need to trim polyurethane foam to form a groove into which the panel will be installed. It should be borne in mind that each fragment must be immersed - by 0.8 - 10 mm. Trimming is done directly next to the frame to form a stronger fit. After all, finishing the slopes with plastic with your own hands requires that all the gaps be minimal, or better, absent.
Cutting foam is made as close as possible to the window frame

This completes the first preparatory stage. It is necessary to perform high-quality cutting of parts. This is very important point, if you make it wrong, then you can't install PVC with your own hands.

Detailing can be done in two ways: take measurements and transfer data to the material, or make a stencil. BUT! Each of the methods must take into account that 10 mm will be needed to be inserted into the groove, and the thickness of the elements themselves must also be calculated, because they will form a common perimeter.

plastic panel

Using a hacksaw for metal or an electric jigsaw, plastic is cut for slopes. Numerous burrs may remain along the edges; they are removed with sandpaper.
Pre-installation in progress. It will help determine if there are defects. If the plastic is double-sided, then the wrong part is marked, it should be sanded a little. This will allow you to achieve better adhesion, because the installation of plastic slopes with your own hands is carried out using polyurethane foam, the adhesion of which to the smooth surface of the material will be much worse.
Now the parts are installed one by one on required space... They are pre-pushed into the groove made. Careful alignment is carried out, a level is used for this.
The outer edge of the element is pushed back and a spot filling of the foam is performed. Extreme care must be taken as excess material will lead to warpage of the fragments.
The details are fixed to each other with masking tape. It is glued at the joints, as well as along the perimeter of the walls.

When pouring polyurethane foam, it is important not to overdo it with its amount.

It takes a day for complete drying. Then a series of additional finishing activities begins. They consist in the fact that window slopes are treated with sealants, a fit is performed decorative corners... They are seated on glue.

You also need to trim the outer bevels. It often happens that platbands are used, they need to be installed around the entire perimeter. If you exclude the use of such products, then the embedding is carried out using a putty, which will be hidden by the wallpaper.

Option number 2

Do-it-yourself plastic slopes can also be mounted using a technology that is significantly different from the previous one. It lies in the fact that fastening is carried out much faster using a starter profile. Any PVC materials are used for work.

The starting profile allows you to carry out work on the installation of slopes several times faster

On a note! Sometimes you can find an abbreviation in the form - PVC. This designation is considered equivalent to PVC, but it was used in Soviet GOSTs for plastic coatings.

The initial phase begins with preparation. It consists in cleaning the surface and removing all defects. The primer must be carefully applied to all areas. General technology further work is as follows:

Sometimes an essential question arises: how to trim the window slopes with plastic, if they have a large width. For this option, there are special wide panels that eliminate the need for grooving.

Installation in progress:

To achieve the best effect, do-it-yourself fragments on the windows begin to be mounted from the sidewalls.
Each detail is inserted into start profile... If protruding surpluses are observed, then they are cut off with a clerical knife.

The material is fixed on polyurethane foam. It is poured in small quantities. It should be borne in mind that there will be more void next to the window frame than at the edge. Therefore, the foam is distributed in such a way that no swelling is observed.
Panels are fixed masking tape that is glued to the walls. The finishing of the window slopes with plastic is considered complete, but finishing activities must be completed.
When the coating is dry, you can start installing the decorative corners. Special attention pay external modules, they are joined and cut at 45 degree angles. Installation is carried out with glue.
All joints are additionally treated with a sealant. Options are selected that will match the color of the set material.

The final stage of facing the slopes is the installation of decorative corners

On a note! The use of silicone should be avoided. This substance is not suitable for work on visible surfaces. The fact is that such a composition turns yellow very quickly and becomes covered with dirt.

Cladding outside with plastic

How to make plastic slopes outside the room? Indeed, this material can be applied to the outside of windows. But for work, only sandwich panels or sheet plastic with high strength indicators are used. The general technology does not differ from the internal one, but it requires more thorough insulation and sealing.

In fact, slopes made from plastic material- this is perfect solution... There is no doubt that the development of technology will allow to obtain new products that will replace other options.
