Installation of ventilation mode
Ivan master po remontu okon Tbilisi
In Tbilisi, where the climate is mild and frequent ventilation is especially needed during the off-season, the installation of ventilation mode on windows becomes not just a convenience, but a necessity. This option allows you to fix the sash in a slightly open position (gap from 5 to 20 mm), providing constant fresh air flow without drafts. Unlike the standard 180° handle turn, micro-ventilation mode eliminates sudden wind gusts, which is especially important for bedrooms and children's rooms. Additionally, this mode increases safety: the sash is locked and cannot be opened from outside. In residential complexes in Tbilisi — from Vake to Didube districts — modern double-glazed windows are often installed, but without adjusting the fittings for micro-ventilation, their potential is not fully realized. Ivan carefully adjusts the eccentric cams (cam pins) on the fittings so that the sash sits evenly and does not warp. For this, a 4 mm hex key adjustment is used. The result is a comfortable microclimate in the apartment, reduced risk of condensation on the glass, and extended lifespan of the seal.
How the work is done
Ivan carefully checks the type and condition of the locking hardware: cam pins, strike plates, handles. He determines whether micro-ventilation can be implemented without replacing parts.
Removes the decorative cover, unscrews the fasteners, takes out the handle. If the handle has a rotation blocking function — he additionally adjusts it.
Attaches the limiter to the sash using self-tapping screws, after pre-marking the holes. Installs the matching part on the frame.
Rotates the eccentric cams on the sash with a hex key, achieving the desired compression in the micro-ventilation position. Checks that the cam pins engage with the strike plates without binding.
If the sash sags — adjusts the lower and upper hinges in height and horizontally. This ensures a uniform gap around the entire perimeter.
Closes and slightly opens the sash several times, making sure the mode locks in. The handle should rotate smoothly, without effort.
Verifies that the sash cannot be opened from outside in ventilation mode. If necessary, installs an additional lock blocker.
Explains how to properly use micro-ventilation: do not apply force, adjust compression if needed every six months. Provides care recommendations.

Tips from the pro
- Ventilate rooms for 10-15 minutes 3-4 times a day using micro-ventilation mode — this is the best way to refresh the air without drafts.
- In rainy weather, do not leave the window in ventilation mode overnight: humidity can cause dampening of the window slopes.
- Every six months, lubricate the fittings (hinges, cam pins) with machine oil or special window spray — this will extend their lifespan.
- If you notice the handle starting to turn with effort, do not apply force — call a professional. Self-adjustment can disrupt the settings.
- Choose a metal wedge stop rather than plastic — it is more durable and will not break with an accidental sash pull.
- Periodically check the seal: if it has cracked or lost elasticity, it should be replaced, otherwise ventilation mode will be ineffective.
