Aluminum and steel doors and windows

These are typically located at the lowest level of a staircase or a room with high ceilings, and their function is to supply fresh air in the event of a fire following the ventilation of smoke. However, to create a natural draught effect, it is also necessary to install heat and smoke ventilation windows in the upper part of the same room. Their combined operation can not only be a lifesaver in an emergency, but can also be used for daily ventilation. We offer intelligent ventilation systems made of aluminium or steel, which can be operated automatically for maximum convenience.
