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.
Micro-ventilation is the fixation of the sash in a slightly open position (gap 5-20 mm) using special slots on the fittings or a wedge stop. Unlike standard full opening, this mode provides constant fresh air flow without drafts and is safe for children.
This adjustment is possible on most modern windows (PVC, wood, aluminum). If the standard fittings do not provide intermediate positions, Ivan installs an additional wedge stop. For old windows with worn fittings, their replacement may be required.
On average 30-60 minutes per sash. If wedge stop installation is required — up to 1.5 hours. Ivan does not rush, carefully adjusting each component to achieve perfect fit.
Yes, it is safe. The sash is fixed so that it cannot be opened from outside. Even with force applied, the mechanism blocks further opening. Additionally, an accidental opening blocker can be installed.
Yes, regular micro-ventilation reduces humidity indoors, which reduces condensation on glass. However, if windows are heavily fogging, the problem may be insufficient ventilation — in that case, installation of an intake valve is needed.
I recommend checking the adjustment once a year, especially after winter. Over time, the seal and fittings wear out, and compression adjustment may be needed. Timely adjustment extends the lifespan of the mechanisms.
Yes, it does not interfere. The only thing is that if the screen is hinged, it may slightly complicate access to the handle, but otherwise there are no problems.
Notify Ivan immediately. Usually this is due to cam pin binding or excessive compression. Adjustment is done free of charge under warranty.
Ivan services all areas throughout the city: Vake, Saburtalo, Didube, Chugureti, Isani and suburbs up to 30 km away. He works in both private homes and apartments.
Guarantee of 1 year. If anything goes wrong during this period (handle becomes stiff, sash warps) — Ivan will come and adjust it free of charge.
Technically, the installation of ventilation mode is an adjustment of the fittings, not a replacement of parts. Ivan checks the type of fittings (casement, tilt-and-turn) and if necessary replaces the strike plate with a reinforced one that has the ability to fix in intermediate positions. Sometimes it is necessary to install a wedge stop — an opening limiter with 4-5 slots. This is especially relevant for old windows in the Chugureti district, where standard mechanisms do not provide micro-ventilation. The price of 180 ₾ includes a service call, diagnostics, and adjustment of up to 3 sashes. If more is needed, the cost is negotiated. For the customer, the main thing is to pay attention to the rotation effort of the handle: after adjustment, it should become smooth, without jamming. A typical mistake is installing the wedge stop too far, causing the sash not to be fixed in the desired position. Ivan installs accessories strictly level so that the gap is uniform around the entire perimeter. Work guarantee — 1 year. It is recommended to perform adjustment annually before the rainy and windy season, especially in Tbilisi with its fluctuating humidity.
«I often see how people suffer from lack of fresh air in Tbilisi apartments. Installation of ventilation mode is a simple and inexpensive way to make your home comfortable. After my adjustment, you will forget about drafts and be able to enjoy fresh air at any time of year.»
