Our story about the replacement of outdoor glazing in the apartment, started in the IVD, 2011, No. 6 (151), will be incomplete if we are bypass the installation of translucent structures. After all, modern windows are extremely demanding on the quality of these works, and in violation of the technology, no service life, nor other characteristics will not correspond to the declared
The main thing is the sequence
Plastic windows can be installed at any repairs. If paint and plaster works are coming, the openings are simply closed from the inside with a polyethylene film. Ana wooden moisture frames, highlighting with raining of screed and plastering walls, can have a destructive effect: often the parts are boxed and the flaps stop opening and closed. Therefore, wooden windows are better mounted after the end of the main "wet" processes.You give the installation!
In principle, changing glazing in the apartment can be at any time of the year. After all, each window professionals will spend no more than 1-1.5 hours (more time may require installation of large-sized structures - French windows and balcony doors). The exception is made for older (mostly brick) houses, where when dismantling is often damaged by the wall, but it is not easy to restore it in frosty weather even with the help of modern materials.

The diagram of the adjoining unit of the window block to the wall in the house with facade insulation (A) and its thermographic option (b). At the outer air temperature of -27s, the internal slides remains up to 12.5 s, and therefore, during normal humidity, condensate will not fall on them.
Today, the windows from the profiles of the circuit width of 70mm are most in demand, such as Trocal Innowave ("PROFIN RUS") (B). Blocks with a wide (more than 100mm) box, for example, from Aero Suprema profiles (EXPROF) (g) are designed for houses with single-layer walls. They allow you to significantly increase the width of the mounting seam and thus avoid the insulation of slopes.
Experts say that the installation of the window begins with the measurement of the opening. Indeed, errors when performing this task are extremely undesirable, and after all it is not so simple, as the uninitiated. The windows of the windows are mounted in various ways - with the use of packle and cement mortar, tubular seals IT.D. Sometimes the measurer accounts for at random to determine the width of the existing mounting seam, hidden by nachets and layers of plaster. At the same time, an inexperienced worker often acts on the principle of "better block to make less", fearing that he does not fit in the opening. Vitoga Mounting gap is sometimes too wide, and it prevents the design to firmly - it may not even withstand wind loads. Too narrow gap is also bad. The fact is that the material of window frames is subject to temperature expansion and compression. Thus, a linear change in the size of the reinforced PVC profile length 2000mm during the day can be up to 6mm. These oscillations "Gasit" is the installation seam. If its width is insufficient, when expanding profiles can be deformed. In addition, as a result of periodic deformations between the insulation (layer of the mounting foam) and the wall, the gap will appear in which in the winter will be significantly blowing.
Opinion of a specialist
With the freezing of slopes in the frost, it is necessary to face quite often. As a rule, it happens in buildings with single-layer walls (brick or monolithic concrete). Then condensate appears on the slopes (and in some cases it is even formed to be formed), the plaster reaches and affects her fungus. There are several ways to combat the freezing freezing, but it should be noted that the most effective of them will be able to implement only at the stage of buying and installing the window. For example, you can install windows with a wide (more than 70 mm) box or arrange a thermal master of polystyrene through the perimeter. Installation of windows should be charged a specialized organization using high-quality consumables.

1. The principle of installation of the window block in a chopped house: Showing seam filled with mineral wool (A) (it is allowed to use the pass or other frothy insulation); side deformation seam (b); Plumbing box (B); Mounting seam, protected from inside with a foil vapor insulation tape (g); Bar wall (D); Window block (E).
2. Incorrectly used window adjoining window to wallpapers: the gap between the quarter (a) and the frame (b), called the front, is absent, as well as the waterproofing of the insulation; The magnitude of the side mounting seam (B) is more than 60mm; Under the discovery panel (g) - glass gamble (D), in which there is no need.
3. By ordering windows from laminated under the plastic profile tree, many want to get the windows of the same color and with the same texture. It is very difficult, since the window profiles produce some companies, and the window sills are others. But you can buy a window sill of natural or artificial stone or a wood array

GOST 30971-2002 clearly regulates the location of the window in the depth of the opening. If the walls are single-layer, the box is mounted, retreating from the outer surface of the wall for 1/3 of the thickness of the latter. Looms from sandwich panels The window block is installed in the plane of the insulation layer. For fastening the box, in the first case, frame anchors or mounting plates can be applied, in the second - only mounting plates that allow you to shift the mounting sites closer to the room (in the concrete layer). The step of the fastening nodes for window frames from wooden profiles is 800mm, from aluminum and white plastic profiles - 700mm, from color plastic - 600mm. The distance from the inner corner of the box to the fastening element should be 150-180mm, from an exemption to the mounting element - 120-180mm.

Errors when performing installation work: the windows shift towards the street led to the freezing of slopes and the formation of stagnant zones where the fungus settled (a); The restoration of the outer slopes was left "for later", as a result, the mounting foam began to crumble, and the sealability will be returned to the seam (b); The mounted gap is not moistened, and the foam is not completely polymerized - the process ended after the first heavy rain (B); Due to the unreliable mounting of the window block in the opening and lack of supporting pads, double-glazed windows collapsed (d)
After the filming of the mounting gap, the insulation from the inside and the outside are protected using special tapes - vapor and waterproofing vapor-permeable, respectively (psuli - pre-compressed sealing tape - refill in the frontal gap between the frame and quarter). It is also permissible to apply mastic and sealants. However, if the tapes can be pasted after 10-20 minutes after the clearance is filled with foam, then the coating materials are applied only after the polymerization of the foam mass, cutting off the excess insulation.
Possible compromise
If you have delivered a set of details and in place it turned out that the width of the side mounting gap exceeds the normative (it is worth measuring it, after the window is fixed in the opening), you have the right to refuse the installation. Another option is to agree to the use of a good profile. It has a rectangular cross section and "rustled" to a box from one or more sides. Light opening will decrease a little, but the firm will provide you with a solid discount. In no case cannot be filled with too wide a gap alone by mounting foam.The three-layer design of the mounting seam is a prerequisite for its durability. The absence of an internal vapor barrier layer leads to saturation of foam moisture contained in indoor air. This moisture, expanding during freezing, destroys the structure of the material. If the foam is left open from the outside, it will be rapidly age under the influence of precipitation and ultraviolet rays. Moreover, through the mounting seam, filled with one foam alone (without protective layers), moisture may even get inside the room. The symptoms of the destruction of the mounting seam recognize is not difficult: on the perimeter of windows begins to blow, wet spots appear on the wall under the windowsill. The only "medicine" from this - re-install the window.

According to the definition, which gives GOST 23166-99 "Blocks of window. General technical conditions", a window is an "element of a wall or roofing design ... consisting of a window opening with slopes, a window block, a sealing seal sealing systems, a sub-circuit board, drain parts and facing. " So, under the installation of the window, it should be implied not just installing the window block, but also the finish of all surfaces of the wall opening. Of course, you can refuse part of the work, but the cost of services should be reduced.Not glue one
The windows board must be firmly fixed. Very bad if she suddenly collapses, not withstanding the severity of the next flower pot. PVC window sills are fixed mainly by mounting foam. For more heavy products, special adhesive compositions are suitable. However, they are applied by a thin layer, so the supporting area should be smooth. If less than 2/3 of the windows width is based on the wall, do not hope that only glue or foam will be kept. In the case, the case should be closed the edges of the window sill in the wall, making a remark on both sides of the opening.
In love case, the installers are required to restore external slopes, if their surface was damaged when dismantling old windows. To do this, use white facade plaster, frost-resistant glue for tile or cement mortar (if the wall is not painted or laid out of the brick). Then, with the help of special adhesive tapes and self-tapping soles. Do not neglect the sonological gasket for this element - it makes it much quieter of rain sounds and drops.

Internal slopes can be separated in several ways. Most often, they are plastered by cement or plaster mixture. At the same time, on a smooth concrete, there are notches or treated with adhesive primer. After the putty dries, the slopes are covered with washing paint. If the plastic window, a crack will definitely be sure to appear between the box and the plastered slope - this is a natural consequence of thermal expansion and narrowing PVC. To not be seen, it is advisable to apply a special narrow nickname equipped with a flexible polymer petal.
Opinion of a specialist
The window box is installed in the opening on the support pads, which have under each vertical element. These pads are absolutely necessary, and in the future they remain in their places, preventing the deformations of window profiles. The required stage of the assembly process should be dusting the wall. Indeed, on the outer sides of the frame there are special curly protrusions, for which the foam after curing is firmly "hooked", and the adhesion of the composition to the whole entirely depends on the preparation of the latter. In addition, the surface must be slightly moistened - this will contribute to the full polymerization of foam.

Often, the slopes are drawn up with the help of decorative panels. If the window is plastic, most often used PVC sandwich panels filled with polyurethane foam or polystyrene foam, as well as plates from PVC foamed - these lightweight products are fixed to the frame using special profiles. The panels are not cracking, and condensate is not formed on them, since the surface of the plastic is always free to room temperature. On the joint of the panel with the wall you have to glue a corner of PVC, which does not take the window opening. But this is perhaps the only drawback of plastic slopes.

When installing wooden windows, the opening can be separated by thin (not thicker than 20mm) glued shields painted in the color of the frames, cale the surfaces of the cork veneer or use the Dobly Planks from MDF - laminated or veneered wood veneer. Experts are not recommended for sneaking with drywall, since on a relatively soft surface of this material, dents from random strikes quickly appear. There are often cracks on the joints of the GLC bands with a wall and a window box, and if condensate falls on the slopes, the finish will be hopelessly corrupted.
