Why assembly joints when installing windows should be in accordance with GOST: workshop

Assembly seam nodes contiguity window units according to GOST, personal experience of the participants of the portal

Plastic windows in one or another version ubiquitous and high-rise buildings, and in the private sector. But in addition to the characteristics of the design, not less important is the correct installation, on their own or with the assistance of the masters, the main thing - respect for technology. The main attention is often given to a reliable fixation unit in the opening and the ideal plane, while the seam, "zapenil, closed, forgotten." Given that quality installation joints, is the key to opening the tightness and trouble-free operation of the window for many years. Consider why the seams are important, GOST, as well as the recommendations of our members, based on personal experience.

Functional construction joints

Consider mounting a seam gap around the perimeter of the window you want to seal the foam, with PSUL (Pre-compressed sealing tape) or not, and to close (frames, flat strips, plaster and al) -. erroneously.

This technological gap with the regulated parameters and a number of functions.

Everything is very simple. Assembly seam insulates the wall from the window. The temperature of the wall in the place of installation of the window lower than that of the window and to the window frame is not received less from the wall and need assembly seam. The most important purpose of an assembly seam - split two different thermal conductivity of the material.

Filling the same, whether it is foam or something else, is tight:

• protects from blowing;
• isolate the room from external atmospheric influences;
• It prevents the outflow of warm air from the room.

And also, "friendly" with the opening window assembly.

... The whimsical place, this docking space materials, various in nature. Here also it helps the foam, which is better than these materials on thermal physics.

The most important parameter is the mounting seam width.

House of aerocrete 400 mm. What is the margin for mounting seams side / bottom / top to recommend? Embodiments found from 10-15 to 30-50 mm. What target? The idea is that lower seam - more window. Installation of windows in a wall opening of aerocrete 400 mm. Advise how correctly.

Not exactly an option to save on window units due to increased joint. As too broad and very thin seams - are equally undesirable.

The starting point is taken the profile of the material and dimensions of the window, as in wood, metal and PVC different linear expansion and temperature fluctuations in our climate are tens degrees.

Also, there is a perception that zamerschika installers specifically deliberately left large gaps in order to eliminate possible shoals and simplify installation. And indeed, a situation where the "master" to put it mildly, not a pro, take place to be.

I'm not the installer, but the windows installed itself, and for this reason had much to shovel. The main reason for setting self - incompetence arrived gager, he's assembling. When communicating realized that he did not know his business. The man sounded 25 years of experience of installation of windows. To my question, at the expense of the primer - he had "fallen out" eyes. The question of which method is better attachment, more startled response - "As you say, and we fix." In general, it was necessary first to delve into the theory.

However, the dimensions of the assembly seam regulated by the state standard, rather than assemblers.

Mounting stitches on STATE

Currently, this area acts GOST 30971-2012. Sutures mounting assemblies abutting window units to wall openings. General specifications (to replace GOST 30971-2002). If desired and necessary, it is possible to study in detail, since apart directly seams, there weight of other useful information on installation of window units. But briefly at the seams:

Node contiguity window (balcony) unit to wall gap.

• The central layer
• The outer sealing layer
• The inner sealing layer
• Optional sealing layer
• Low tide
• windowsill

to the size requirements.

Dimensions of the mounting gap.

According to the participants of the portal, the optimal width of the seam, in terms of heat engineering, ease of installation and ease of further internal and external finishing - 20-30 mm.

tehnologSPK

The single-layer walls in places other than the windows installation assembly seam of 20-30 mm, it is recommended to make the grooves and mount them in a heater. As a result, the width of the assembly seam is designed to ensure that prevent freezing of the window, and node-slope window, rather than simplify the installation installers.

…Personally, I found that less than 20 mm in the seams is not worth doing, even at installation and then at the finish. Yes, and do more than 30-40 mm gap is also not worth it, for the same reasons of convenience and quality, especially when working with foam.

The design of multi-layer construction joints:

• main - providing thermal insulation and sound insulation;
• outer - providing free steam exits from the main seam and protection from external influences (UV, wind, moisture);
• internal - vapor barrier, protection.

Whatever materials are used as the structural or construction joints, they should be leak-proof and prevent the freezing circuit. And also be durable and resistant to operational stresses.

Discussion at the seams turned constructive. I would like to hear more from the assemblers, what do you think of the materials for the installation and the technology described below.

• Pre-treatment of aerated concrete: primer, then STIZ-D.
• Fastening windows: plate mounting step to 700 mm, yield terrace on the anchor bolts.
• The bearing pads: plastic.
• Waterproofing (Street) permeable sealant STIZ-A or analogues.
• Mounting seal: polyurethane foam.
• Vapor barrier (of the room): vapor barrier tape.
• Additional sealing connectors and extenders PSUL tape.​

tehnologSPK

Further support shoes, plates and foam, everything else – a waste of money. I argue.

• Polyurethane foam is negligible paronitsaema.
• Polyurethane foam is negligible hygroscopic.
• When the inner and outer trim foam is closed inside and outside, which create a barrier, as well as sealants. The inner slope is denser, so usually the inside tighter than outside, observed.

Of course, you can do that the plan would not be bad, but not as bad will and without special stages.

Output

The width of the assembly seam is important both in terms of heat engineering, and with the ease of installation positions of windows and further finishing the inside and outside. Sticking to whether the guest, a private matter, the argument "I have a seam 1 cm, but the condensate, especially mold, no," often causes a lot more confidence than the standards. Nevertheless.

Guys, if you have not noticed, there are people with long-term, practical experience and advice is given not on the basis of theoretical reasoning, but on the basis of experience. If you are lucky and there is no condensation, then rejoice, not all was still bright.

Find out, how to combine the panoramic glazing and energy efficiency. If glazing is only in the plans, read a burglar windows, It might make sense to think about the security at this stage. In the video - master class in large-format installation translucent structures concrete blocks opening.
