In the process of building a house, many owners have a question about when the windows are being installed. It is important to know that natural wood structures are installed after the completion of interior finishing work, such as ceiling screed and plastering.
Before starting installation, the building should dry out a little, since high humidity can lead to swelling of the natural material and its cracking, as well as damage to the paintwork.
To reduce air humidity, you can use gypsum board instead of plastering for wall decoration. In this case, the installation of the window structure can be carried out after screed on the walls and before finishing with plasterboard.
If you prefer plastic windows for your home, they can be installed both after and before finishing, since the PVC structure is not susceptible to moisture. However, it is important to remember that if the walls are finished with plasterboard, the windows must be installed before using it, since the material is not moisture resistant.
Performing work in the winter: the main subtleties
The main construction processes: laying the foundation, erecting walls, organizing the roof, fall on the warm season. In autumn and winter, it is time for interior finishing work. After the installation of metal-plastic windows in the house, it is necessary to start the heating system. In winter, it is recommended to use drywall sheets for wall decoration. The choice of this material does not greatly affect the level of humidity in the room, but it will significantly speed up the repair work.
If the owners plan to install windows made of natural wood, dry plaster is used for finishing work in order to avoid swelling of the frames.
The key to success: the right microclimate in the room being repaired
The speed and quality of work is largely dependent on humidity and temperature. In houses where plastic windows are installed, it is necessary to improve the natural ventilation system. For this, the windows are left ajar, and fans are mounted in the ventilation ducts.
It is also necessary to control the temperature. Until the screed and plaster are completely dry, the value on the thermometer should not fall below + 5 ° C. As an alternative to the traditional concrete screed, it is possible to partially use a prefabricated dry screed. This choice will speed up finishing work by reducing the amount of construction moisture.
We carry out finishing work in the summer
Interior decoration of a room is an important and time-consuming process. Before starting the repair, it is advisable to complete the installation of plastic windows. Especially if the work is scheduled for the spring.
Installation of windows includes several stages. Upon completion of the installation, repairs and alignment of the slopes are carried out. Then proceed to the treatment of the walls with cement mortar.
The installation of wooden windows should be postponed until the end of the internal work.
It is important to remember that a draft will cause the wallpaper to peel off and the paint will “bloat”. You can protect the room from air penetration with a film. It is enough to fix it on the window opening.
The slopes must dry out after finishing work. Therefore, at the initial stage, the solution should be applied only to the walls. Wooden windows are installed last.
At the final stage, the window slopes should be plastered. Craftsmen also use an alternative method of cladding - plasterboard finishing.
On walls that are not insulated in any way, you can plaster the facade both before and after installing the windows. However, it is still recommended to carry out the work after the installation of the windows. This will make it possible to carry out all subsequent finishing work faster and more efficiently. After the installation of windows, the arrangement of slopes and external ebb tides can be carried out immediately. These works make it possible to avoid further alteration of the facade. If the plaster was applied before the installation of the windows, then the subsequent plastering of the facade will be very different.
If the plans include the organization of two-layer walls, then initially they perform
installation of windows, and then the insulation is laid and the facade is plastered. In addition, this sequence of installation allows for better finishing work.
external slopes.
So that after warming the facade it is possible to apply plaster, slabs
impose 2-3 cm on the window opening. Can't be allowed in the corners
windows formed joints of insulation slabs. Therefore, the slabs are cut, giving them
the shape of the letter "G". And then they are attached with a cutout in the corner of the window.
For the period of the plastering of facades, specialists cover the windows with a film, which is fixed with adhesive tape. Upon completion of the work, it is removed. It is not recommended to fix the film with molar tape, because after its removal, traces remain on the window.
Construction installation rules
When ordering windows, you must invite a company specialist who will clearly measure the dimensions of the future structure.
The product is installed at an outdoor air temperature of at least -5 ° C. Lower values can lead to the appearance of microcracks and chips on the plastic elements of the window. In addition, negative temperature indicators lead to a deterioration in the adhesion of the polyurethane foam to the wall.
Fixing the window structure to the wall
The window is mounted in the opening with the help of special bars, leveling in the vertical and horizontal directions. It is fixed to the wall using one of two methods - frame dowels and steel anchors.
In the case of using an anchor, one end of it is fixed on the window, and the other on the wall. Such fasteners can be used to fix window blocks made of various materials.
The frame dowel is not such a universal solution, since it forces you to make changes to the design. To fix the frame with it, a hole is drilled in the window profile and in the wall. A dowel is installed in the formed channel and tightened. All work is carried out by installers carefully, since too much twisting of the dowel can lead to deformation of the window.
Upon completion of the installation of the window structure, the joints around its perimeter are foamed, and the material from the outside is protected with a vapor barrier tape or a special liquid sealant. It allows you to prevent the influence of negative external factors on the foam.
Placing a window in a wall
It is required to correctly position the structure in the outer wall, as this will prevent the appearance of "cold bridges".
When installing the structure in a single-layer wall, it is placed closer to the middle, which reduces heat loss. In double-layer walls, the window block is mounted flush with the outside of the masonry. In this case, it is important that the insulation goes into the profile at a distance of about 3 cm, overlapping the joint between the wall and the frame.
In the case of building a house with three-layer walls, the window structure is mounted in an insulating layer, in the immediate vicinity of the masonry of the load-bearing part of the wall. The resulting gap is filled with a special tape, which prevents negative effects on the structure of moisture and temperature extremes.
Building a house? All construction and installation work must be carried out in a specific order. In our climate, cottages are often glazed on the eve of winter before decorating the walls. But finishing work is associated with moisture and dirt, which threatens new glazing. In this article we will tell you what to look for in order to decide when to put windows. "/>
Building a house? All construction and installation work must be carried out in a specific order. In our climate, cottages are often glazed on the eve of winter before decorating the walls. But finishing work is associated with moisture and dirt, which threatens new glazing. In this article we will tell you what to look for in order to decide when to put windows.
Before or after wet work?
Install wooden profiles after the end of the "wet" work to avoid damage due to excessive moisture. First, plaster the wall, make a screed, and then carry out the installation. When the "wet works" begin, the profile systems lose their warranty. After all, profiles installed at high humidity naturally quickly deteriorate.
PVC glazing is possible before and after wet finishing. The main thing is that the outside is at least five degrees below zero, and the room is not too humid. Constantly ventilate the rooms, then condensation will not appear on the double-glazed windows, slopes, and mold will not appear.
Glazing before or after facade finishing
It is irrational to install PVC windows after plastering the external walls - the slopes have to be covered with plaster twice. Moreover, the first layer of the coating is damaged, especially in the presence of a vapor-permeable tape at the junction of the profiles. The aesthetics of the design can be disturbed by the uneven color of the plaster due to its application at intervals. Install the profile before equipping the facade in order to facilitate the sealing of joints and beautifully finish the slope.
It is permissible to glaze openings with thin walls before and after plastering. The first option is preferable. Before starting the final finishing of the external walls, carefully shield the profile systems with a protective film to protect them from the cement.
For double-layer walls, glaze the openings before insulating the facade. Then it will become clear where to place the foam. Its slabs must be positioned so that there is no overlap of the edges in the corners. Reinforcing material must be applied to the corners of the opening. The overlap of the thermal insulation material on the frames should be approximately 3 cm.
Are you installing euro-windows in non-insulated walls? Insulate the seams between the window system and the wall. Do you insulate the opening before installing the profiles? Lay the insulation material with a margin.
Winter wet finish
Construction is usually completed in the fall, and glazing is performed in winter. For installation work in winter, buy plastic profiles suitable for installation all year round. And with seasonal sealant, they are not installed at outdoor temperatures below -5 ° C. Is winter cold? Wait for the glazing of spring days. Otherwise, PVC can collapse, becoming brittle in the cold. It will crack during transportation and installation.
Winter glazing
Install wooden windows in spring. If time is running out, do dry finishing works instead of wet ones. Have you glazed your house in the winter? Then ventilate the building regularly to prevent condensation.
Glazing and plastering
It is better to install windows after the "wet" finish and before the finish of the facade. In practice, the order of work is different due to the fact that the owners are in a hurry to move into the house.
- Before plastering the walls... In the spring and summer seasons, the openings are glazed even before the "wet" works. The profile must be covered with a protective film. Or you can remove the sash from the opening and close the frames well while the walls are being plastered. Upon completion of the glazing, you can plaster the corners, slopes, cover the profiles with a special film, plaster the remaining areas of the walls. When plastering, the room should be at least 5 degrees Celsius. In winter, install eurowindows or PVC windows before plastering. Fix wood systems in the openings when the plastered wall is completely dry.
- After plastering... Plaster the walls without covering the slopes and corners with the mixture. Once the walls are dry, you can install windows. When the polyurethane foam hardens, cover the slopes with plaster. In this order, wood profiles are installed so that they do not come into contact with excess moisture. It happens that the slopes are not plastered.
With plastered slopes and walls, it is extremely difficult to glaze openings without damaging the finish. Glazing after "wet" works avoids damage to frames and glass bags during finishing. In order not to scratch the profile, cover the block with frames with foil before insulation.
Why is illiterate editing dangerous?
We recommend installing window and door profiles after the screed, plaster has dried, and the outer wall has been insulated. Then the insulating material will not accumulate excess moisture, and condensation will not appear in the insulation, it will not freeze in the foam, and will not destroy its structure.
Excess moisture can swell wooden frames, paint cracks, and fittings can rust. The glazing is guaranteed under "normal" operating conditions. That is, when the room is about 20 C, and the humidity is not higher than 60%. Therefore, carefully consider the course of work to avoid additional costs and damage.
The advantages of installing PVC windows in the fall
With the onset of autumn, rains and cold weather, old windows show themselves from the worst side. Drafts begin, rainwater gets in, and so on. In this case, the right decision is to replace wooden double-glazed windows with new PVC windows. At the same time, there is an opinion that it is better to install PVC window systems in the summer season. And autumn and winter are not considered the best periods for this.
But this statement was true only in those days when the industry of production and installation of window structures was at an initial level. Then technologies were not as advanced as they are today, and the quality of materials was not as high. Today, the level of production development makes it possible to order plastic windows in autumn and winter. Installers have all the necessary skills and tools for the correct installation of plastic windows in the winter. At the same time, the client even receives additional bonuses.
Why is it profitable to install PVC windows in autumn?
Let's take a look at the main customer concerns when installing window systems in the fall. Many are afraid that during the installation hypothermia of the room will occur, where the work is being carried out and the whole apartment will be cold. Here it must be said that the main process of replacing a window occurs in 40 minutes or at most an hour. All this time, the window opening will be open, but no hypothermia of the room will occur. And even more so, walls or batteries will not freeze. Household appliances and appliances will not be affected either. Only indoor plants can suffer from this, which can be transferred to another room and the door closed.
Clients cite the poor quality of installation work at low temperatures as another problem. However, this is not a cause for concern. Installation of PVC windows is quite possible at temperatures up to minus 15 degrees Celsius. When youorder a window in the company, the specialists will choose a suitable day for installation. Prior to the work, special winter building materials, polyurethane foam, sealant and so on are used. These substances retain their properties at subzero temperatures.
In addition, when installing windows in autumn or winter, the draft is always felt more. Therefore, after installing the structures, installers will find it easier and faster to find flaws in the form of drafts, cracks and cavities. And immediately they will be repaired.
As a benefit to the client, a faster order fulfillment in the autumn period is offered. When autumn and winter come, construction work stops, and companies have fewer orders. As a result, they get the job done faster. Workers in production, assemblers and so on are released. Therefore, small orders for the glazing of offices, apartments, cottages are carried out quickly and optimally.
In addition, it is worth remembering about the various discounts in the autumn and winter periods that the company provides to its customers even for small orders. So, the installation of PVC windows in the fall does not lose quality, compared to the summer installation. If you need to install windows in the fall, do not postpone it until the spring or summer. Naturally, such an installation should be carried out by experienced installers with professional tools and finishing materials.
Modern windows are installed not only to replace old wooden ones, they are often given preference for the construction of new housing. What if the process of installing a window unit fell on the winter? Is it possible to install plastic windows in winter, or will this process have to be postponed until spring?
When to mount windows
Of course, it is best to make a leisurely replacement or installation in the warm season under normal weather conditions and positive temperatures. But, if the construction of a new house has been delayed, then the installation of plastic windows in winter is also possible. The same applies to replacing old windows with new ones. There are positive aspects in this season, but you need to take into account some of the nuances. So is it possible to install plastic windows in winter?
Advantages of winter installation
Windows in our country are a seasonal product. Most consumers are trying to be in time to carry out the installation in the spring and summer, when it is more convenient. Most often, window installation companies during this period work with an increased load, so the owners have to wait longer for the order to be completed.
In winter, the demand for assembly and construction work drops sharply
The installation of windows in winter, on the contrary, gives an advantage in the quality of order fulfillment. Most of the construction work, including the installation of windows, is less in demand during the cold season. At this time, you can find interesting proposals for the manufacture and installation of window systems: promotions, discounts and others.... In addition, the installers will not be in a hurry, since the schedule is not so tight, which will affect the quality of the installation. These are the main advantages with which you should not be afraid to carry out winter installation of windows.
The nuances of the cold season
It is important to consider the temperature at which the installation is carried out. It is forbidden to install plastic windows in winter at rates below -20 degrees... In this case, construction foam, which is used as a sealant, will contain a large amount of ice crystals, and the quality of such an installation will be much lower. And after a while, there will be consequences such as freezing and mold.
Also, with too much frost (-15 and below), the seals of opening windows become less elastic, which can lead to poor-quality adjustment of the sashes.
Seal for PVC windows loses its quality during installation at temperatures below 15 degrees If you are planning the winter installation of plastic windows in a new building, then at permissible air temperatures, all work can be carried out without problems.
Another thing is replacement in living quarters. It should be borne in mind that the installation time is 30-40 minutes for each glass unit, and the rooms will cool down at the same time. To do this, in contrast to the summer period, it is necessary to dismantle and change double-glazed windows in stages.
In winter, after delivery of double-glazed windows, they need to be kept in the house at room temperature for 24 hours in order for all the elements to warm up. This is done in order to avoid thermal deformations..
Another option for winter installation is to carry out the so-called warm installation of window systems.
Winter installation technology
Installation of window units in winter is complicated by low temperatures and hanging humidity. It is necessary to somehow level these negative conditions. For this, installers can use two methods of winter installation of double-glazed windows.
The simplest winter installation
As mentioned above, in winter, some nuances must be observed in accordance with the time of the year.
In the cold season, frost-resistant polyurethane foam must be used to seal the joints. - Firstly, for sealing, you need to use polyurethane foam with frost-resistant components in the composition.
- Secondly, in the cold season, when foaming joints, a "heat" gun is used. With the help of it, a layer of applied foam is heated from the side of the street. And only then they start filling the gaps with foam from the inside. This is done to fill all voids with a sealant (foam).
- Third, it is a phased installation. That is, having dismantled the old one, a new one is immediately installed, and so in turn, working with each opening.
- Fourth, the mounting tape is attached in warm conditions. If opportunities permit, then before removing the old ones.
- And fifthly, the hydro and vapor barrier tape (PSUL) during installation is also warmed up by a "heat" gun.
With the help of a heat gun, the surfaces of the joints and the PSUL tape are heated This is the most elementary "winter" technology for installing double-glazed windows, without which it is impossible to obtain a high-quality result.
Warm installation
The use of this technology will increase the cost of installing windows, but its use allows you to smooth out the conditions of the winter season.
Warm installation diagram What does the technology of warm installation of plastic windows provide?
- Warm installation of windows is a mandatory external sealing of the opening.... To protect the installation site, a protective screen is attached to the opening from the street side. The heat shield for the installation of windows restrains the heated air in the room and does not allow the installed double-glazed windows to freeze. In addition, this protection will prevent excess moisture from entering.
- For sealing, as in a conventional winter installation, frost-resistant polyurethane foam is used.
- Mandatory observance of the internal sealing of the joints between the frame and the opening. Indoors - silicone (sealant that prevents moisture from entering). The middle layer will be polyurethane foam, which serves as a seal and joint insulation. Outside, all gaps are covered with waterproof tape.
Installation of windows in winter provides for a work algorithm similar to the usual one for installation in the warm season:
- The opening is closed;
- dismantling of old frames;
- preparation of the surface of the opening;
- installation work;
- finishing of slopes.
The protective screen ensures reliable and high-quality installation of PVC windows in winter The use of warm installation technology is more preferable in winter. A protective screen in combination with materials will ensure a better installation without additional risks (destruction of the seal, the appearance of mold and mildew) in any of the types of buildings (brick, panel or block house)... In addition, the use of triple protection for warm installation will increase the tightness, which will reduce heating costs.
Additional work
A prerequisite for high-quality installation both in winter and in summer will be the finishing of the slopes of the window opening following the installation.
Why is this additional work needed? The main function of finishing slopes is to protect the gaps between the window and the opening from temperature extremes and moisture. Foam is an excellent sealant and insulation, but it is very sensitive to UV rays and moisture. If you do not close the gaps, after a month the seal layer will lose its properties, and by spring it will begin to collapse.
It is better to finish the slopes of the window opening with insulation After installation, finishing works are underway. It is best to make the slopes warm, that is, with an additional layer of insulation (foam, mineral wool)... In the schematic drawing, you can see one of the options for insulating an internal opening. These are not very high costs. But in this way the thermal insulation of the window will be improved.
How high-quality installation
How to understand that the windows were installed without breaking the technology?
- The glass unit does not fog up and does not freeze.
- There are no drafts from under the frame or sash. When installing windows, they are regulated and set to seasonal settings. You can check for a draft by holding a lighted match or lighter to the window. If the light does not hesitate and does not go out, then the sealing is correct.
- The sash opens easily without the use of significant efforts, the same applies to the transition to the ventilation mode.
- When opening or pressing on the frame, there is no backlash of the entire system.
- There should be no gaps between the profile and the window opening.
- All joints with ebbs and window sills are carefully siliconized.
The installer is obliged to check the quality of work and provide warranty service for double-glazed windows Also, during operation over a significant period of time (several seasons), the frame should not sag and loosen in the opening. And all the accessories work correctly, without jamming or failures. If there are violations from those listed in the list, then you need to contact the company installer... Usually all manufacturers and installers give a service guarantee and such defects are eliminated free of charge.
The answer to the question whether it is possible to install plastic windows in winter is yes, but taking into account some nuances. One of them is the observance of the temperature regime. Installation of PVC windows in winter is a more demanding process in terms of technology, but it is possible, just like in summer. In addition, correctly installed plastic double-glazed windows will significantly reduce heating costs.
For example, you will find out what results you can expect after assembly in a different period, and you will also get acquainted with the successful stages of construction, which are the most successful for installation.Most often, many are mistaken and make gross mistakes, installing windows in the cold autumn in bare walls, hoping to tighten the "box" and complete the wet and black finishing work to the end.
Negative consequences of non-compliance with the rules for installing windows
It is recommended to install PVC windows after all screeds and plastered surfaces are dry, but only before laying the insulation of the outer wall. With this installation order, first of all, the accumulation of excess moisture in the insulation is excluded, due to which condensation may form in the insulation layer in winter. And such an accumulation of moisture may well lead to further freezing of condensate and directly damage the assembly seam.
If you are a fan of wood, then before installing wood windows, you need to monitor the level of humidity. Since at high humidity, swelling of the frames near the window and corrosion of other components can occur. Such windows are created primarily for conditions that are close to optimal, where the humidity inside is no more than 60% and the temperature is about 20 degrees Celsius. Indeed, only under such conditions, the operation of wooden windows provides a guarantee from manufacturers.
The best stage in construction for the installation of eurowindows
It is most advantageous to start installing wooden windows after you finish the "wet" work in the room, since it is during this period that high humidity (90%) is a priority inside, which in turn can lead to damage to the window frames. Even manufacturers are trying to warn everyone in advance about the loss of the warranty card, if "wet" work inside the premises is carried out in poorly ventilated, where there is weak heating and humidity in the premises prevails. This is all despite the moisture resistance declared by the manufacturer, so the plastering and screed process must be done before installing the windows.
PVC windows can boast that for them the installation time does not really matter - before, after or during "wet" works. For this type of windows, the main thing is to provide good ventilation of the premises, heating is needed to exclude condensation sediment on the surface of the glass units, otherwise an excess of moisture may well provoke the appearance of mold.
If the installation falls in the autumn or winter season, as well as interior decoration, then in such cases it is of course necessary to choose PVC windows that are not afraid of moisture and can be installed at different times of the year.
Installation before or after plastering
In the spring and summer seasons, PVC windows can also be installed both before and after the "wet" works. It is necessary to protect the windows with a special film, or remove the sash and frame protection for the duration of the work, so as not to damage anything. The minimum temperature for working with plaster is 5 ° C. or more, so that in the winter season, before these works, it is necessary to install PVC windows.
When installing windows after plastering, you first need to plaster the walls inside, except for the slopes and corners, then after the applied plaster has dried, you can install the windows. Slopes are plastered after drying of the polyurethane foam.
