With large-scale repairs in the apartment quite often change windows - to implement modern interior solutions, and at the same time to improve the comfort and safety of housing. We tell about how to monitor the quality of installation of new windows.

Installing new windows can masters from the manufacturer or representatives of a specialized assembly company. The first option is theoretically reliable, but the assembly companies receiving a dealer discount often offer windows at more attractive prices. In any case, only thorough master control at all stages of work can guarantee success.
Measurement of openings

The master should not be mistaken with a width of the mounting seam, which depends on the material and size of the frame. Let's say, for white plastic windows, the optimal magnitude of the mounting seam is 20-30 mm, the retreat from the window quarter is 10-12 mm (the regulatory data for products from different materials is shown in the table). If the gaps are less, the design may be deformed with thermal expansion. And if they are too large, the strength of the frame attachment will suffer, as well as the moisture and airtight of the seam, the decoration of the slopes will complicate.
Measuring openings should be carried out by a qualified master from the installation company. At this stage, it is sometimes necessary to remove the windowsill and the sleep panels (if plaster slopes - partially knock the plaster). Especially great risk of error in "Stalinki" and early "Khrushchev" (built until 1965), where the rode of the frame adjoining the wall to the wall is often closed with several layers of plaster, and the value of the window quarter is difficult to work. Installation of windows in such houses should be entrusted only to firms with work experience at least 10 years.
The plastic balcony door is mounted on the same principle as the windows, however the wizards should not use standard support pads, as it is undesirable to increase the height of the threshold. If over time the flap saves and the hundred is not worse, the defect is obliged to eliminate the warranty. Photo: Kbe.
You can first assess the level of the company according to reviews on the Internet, and yet it is not necessary to fully rely on the blessings of the brigade. De facto in the absence of control quality decreases.
Dismantling of old windows and preparation of openings

In the production of these operations requires accuracy. Of course, do not do without a cutting and lever tool, but it is impossible to damage the walls. It is not necessary to break the old frames, especially if they have not yet served their time. Many managerial companies demand fees for the disposal of construction waste, but from windows in satisfactory condition you can get rid of both free - it is enough to contact the firm trading in translucent designs used.
After dismantling the old frames, the wizard should remove the residues of the insulation, solution and sealing materials, clean and discharge the discovery to ensure good adhesion of polyurethane foam, as well as hydro and vapor insulation tapes to concrete surfaces.

Do not forget about components for windows
When ordering, it is advisable immediately to complete the window design with mosquito nets (for example, rolled), and also consider the room ventilation system during the cold season. One of the options for solving this issue is an invoice of a vent boiler, which is easier and cheaper to install in production or during the installation process. Do not refuse from child safety locks on opening flaps.Fastening Ram.

The window box is installed and aligned in the opening, laying it on adjustable plastic wedges, which are located in increasing about 40 cm. These elements remain in their places in their places, preventing the lower profile of the box (the mounting foam should not perceive the power loads, as it is easily crushed And over time, partially destroyed under the influence of temperature differences).
In houses with single-layer walls, window boxes are fasten with frame dowels or mounting plates, and in modern buildings of three-layer panels - only with the help of mounting plates, allowing to shift attachment nodes from the insulation layer inside, to the concrete part of the wall. The step of the attachment nodes is normalized by GOST 30971-2002. According to the same document, the minimum planting depth of the dowels to concrete and a brick is 40 mm, and the distance from the edge of the construction enclosing construction during the installation of the dowels should be at least twice the depth of the anchoring (in order to avoid the walls of the wall).
The service life of the window depends on the quality of components, the good faith of the collectors and installers. Therefore, when ordering should be applied to the firm, which provides a comprehensive guarantee for the design and work for a period of at least 2 years - during this time the marriage has time to detect itself.

Warming, hydro and vaporizoation of seam
Polyurethane foam should have a low secondary extension coefficient (Low Expansion marking on the cylinder) so as not to deform the window frames. Photo: Penoplex
As a rule, before filling the gap of the insulation (polyurethane foam), the outer waterproofing is performed, setting between the frame and the window-pouge quarter - pre-compressed sealing tape. This tape has water-repellent properties, but is able to skip steam, so that moisture does not accumulate inside the seam.
As a heater, installers should apply only foam. The filled seam must be protected from moisture - both atmospheric and contained in indoor air. Internal vaporizolation of the seam is considered an additional service. If you will pay about 30% of the installation cost, then the wizard, without waiting for the full polymerization of foam, is sealing it, and then seam seam with a foil ribbon. However, there is a risk that foam, continuing the expansion, breaks the ribbon. In practice, steam barriating seam is better to entrust the brigade of the finishers, who after two-three days will cut the surplus of the insulation, protect the seam ribbon (Izosan brands, Robiteks, etc.) or a layer of steam insulating acrylate sealant (for example, from Linek materials "Steizes" "Sasi"), and then begin the finishing of slopes.

Mounting and windowsill
Tin tump is fixed to the lower profile of the frame using self-screws, sealing joint moisture and frost-resistant acrylate sealant. Under the sump, it is advisable to put a layer of a sizaned material, such as porous silicone rubber, to reduce the intensity of the sound of rain and drops.
Light plastic window sill usually be installed under the frame. Products made of wood and chipboard are fastening with "liquid nails" or polyurethane foam. If less ⅔ the width of the board is based on the wall, do not do without metallic brackets.
You need to choose the window sill in advance, as its material and thickness affect some nuances of the window mounting. So, plastic products. Photo: Crystallit.

Finishing of slopes
Steam and waterproofing tapes are needed to protect the insulation from moisture. Photo: "Ralinterstroy"
If the surface of the outer slopes was damaged when removing the old windows, it is necessary to restore them. To do this, you can use the finished high-quality plaster mixture, frost-resistant glue for tile or a strong cement solution. Before applying plaster, you need to protect the window frame with painting scotch and make notches on the smooth concrete or handle the surfaces of the primer improves adhesion. Staining the slopes of only washing paint.
If the plastic window, between the box and plastering, most likely, a filamentary crack will appear - this is a natural consequence of thermal expansion / narrowing PVC. The self-adhesive flexible oscillator will help close it, which must be included in the window of the window.
Internal slopes are better to stucked by moisture-resistant cement mixture. Use gypsum compositions can be used only for finishing alignment.
Sometimes the inner slopes are made up with decorative plastic panels that are joined with a window box using a P-shaped profile. When installing wooden windows, you can use thin shields from an engineering array or ready-made goodness from laminated MDF.
Installation stages to pay attention to
The window boxes delivered to the apartment must be equipped with stacked profiles that protect the frame from damage and simplifying the installation of low tide and windowsill. Photo: DeceUninck (5)
Masters are required to remove the protective film from the street surfaces of the windows
For fixing the frame can be used as plates
So and dowels - depending on the material and wall design
If the sash is placed without glazing, make sure that when installing the latter, you do not forget about the supporting dies

Thoroughly align in two planes and check the absence of diagonal deformations
For reliable fixation, a step is important, as well as the depth of landing of the dowels; Make that these parameters match the GOST requirements.
The sampling is required to install so that there is no gap between it and the standing profile
Saving the assembly foam is unacceptable - seam is required to fill in the whole depth
The windowsill are mounted horizontally or with a barely noticeable bias towards the room; It is obliged to withstand a load of at least 100 kg, attached to a speaker in the room
After complete polymerization of the foam, you can proceed with the decoration of the slopes
Typical errors when mounting windows
- The window is set to ourselves obliquely or with skewers. In the first case, it will be more difficult to separate the slopes and the aesthetics will suffer. In the second - it is possible to jealous when opening the sash, a disruption of the tightness of the action.
- The seam is filled with foam not for the whole depth - in winter it can darken.
- The insulation layer (foam) is not waterproofing outside and / or is not protected by a vapor insulating ribbon from the inside of the room. As a result of atmospheric influences, foam will begin to collapse.
- There is a wide window sill without ventilation holes. The window will fog.
- Slopes are insulated with mineral wool. In this case, the dew point shifts on concrete surfaces, and they repense. As a rule, it is enough to separate the slopes with sandwich panels.
