Plastic windows are sealed constructions and, unlike old wooden windows, prevent natural air exchange in the room. All plastic windows, installed by our company, have a built-in micro-ventilation as standard.
The advantage here is that there is no additional installation, the system does not allow the penetration of rain and there is an additional good anti-breaking protection in the fixed micro-ventilation position.
This is a great opportunity for safe, secure and efficient ventilation of premises and thus prevents condensation.
The system of multi-stage micro-ventilation allows to fold the sash gradually. Multi-stage micro-ventilation allows you to open and lock the leaf at a distance of up to 1 inch from the frame. In this case, the flap folded by turning the handle 45 degrees upward is fixed in one of the 5 selected positions, ensuring the flow of fresh air of varying intensity into the room .
The position of the window can only be changed by pressing the sash against the frame. If you try to move the leaf to another position without pressing, the leaf without the lock can hang on one lower loop, which is fraught with a breakage of the hardware.
The fault lock, which is installed by default in all windows produced by our company, will not allow the sash to be moved to another position if it is not pressed against the frame and thus protects the fittings from breakage.
