Functional assembly joints

In addition to the characteristics of the design itself, proper installation is no less important, either on your own or with the assistance of craftsmen, the main thing is compliance with the technology. The main attention is often paid to the reliable fixation of the block in the opening and the ideal plane, while the seam, “zapenil, closed, forgot”. Despite the fact that high-quality installation seams, this is the key to the tightness of the opening and trouble-free operation of the window for many years. Consider why seams matter, GOST, as well as recommendations. ⠀

🚧 To consider the assembly seam simply as a gap around the perimeter of the window that needs to be filled with foam, with PSUL (pre-compressed sealing tape) or without, and close (platbands, nashchelniki, plaster, etc.) - wrong. ⠀

☝ This is a technological gap with regulated parameters and a number of functions. ⠀

💡 Everything is very simple. A mounting seam isolates the wall from the window. The temperature of the wall at the installation site of the window is lower than that of the window itself and so that the window frame does not receive minus from the wall and an assembly seam is needed. The most important purpose of the installation joint is to separate two materials that are different in thermal conductivity. ⠀

Filling, whether it is mounting foam or something else, ensures tightness: ⠀

🔸 protects against blowing ⠀
🔸 isolates the room from external atmospheric influences ⠀
🔸 prevents the outflow of warm air from the room ⠀
🔸 and also, the window block with an aperture is ит friendly ⠀

The most moody place is the docking of materials of different nature. Foam, which is better than these materials in thermal physics, helps here. ⠀

🔶 The most important parameter of the installation joint is the width. ⠀

⚠ IMPORTANT: the dimensions of the mounting seam are regulated by the state standard, and not by the installers. ⠀

Mounting seams according to GOST ⠀

Currently, GOST 30971-2012 is in force in this area. Seams are mounting units for adjoining window blocks to wall openings. General technical conditions (instead of GOST 30971-2002). If desired and necessary, it can be studied in detail, since besides the seams themselves, there are a lot of other useful information on the installation of window blocks. ⠀

📋 But in short at the seams: ⠀

The junction of the window (balcony) block to the wall opening. ⠀

1. The central layer ⠀
2. Outer sealing layer ⠀
3. Inner sealing layer ⠀
4. Additional sealing layer ⠀
5. Low tide ⠀
6. Windowsill ⠀

📐 Also, GOST describes the requirements for sizes, according to the materials. ⠀

🗣 In our opinion, the optimal width of the seam, from the point of view of heat engineering, ease of installation and convenience of further internal and external decoration is 20-30 mm. ⠀

🗣 In single-layer walls, in places where windows are installed, in addition to the installation joint of 20-30 mm, it is recommended to make grooves and install insulation in them. As a result, the width of the installation joint is designed to prevent freezing of the window and the window-slope assembly, and not to simplify installation for installers. ⠀

Layered joint construction: ⠀

🔸 main - providing thermal insulation and sound insulation; ⠀
🔸 external - ensuring the free exit of steam from the seam and protection of the main from external influences (UV, wind, moisture); ⠀
🔸 internal - vapor barrier, protection. ⠀

Whatever materials are used in the construction of assembly joints, they must ensure tightness and prevent freezing of the circuit. And also to be durable and resistant to operational loads. ⠀
