During a building fire, the greatest danger to occupants and firefighters is heat and smoke. The purpose of heat and smoke ventilation openings is to prevent the spread of fire and to ensure the efficient extraction of smoke and heat from the building. This minimizes damage and increases the chances of survival for those inside during a fire.

Our company manufactures custom-sized heat and smoke ventilation openings from aluminium and steel profiles that comply with the MSZ EN 12101 product standard. These specialized openings ensure the efficient extraction of heat and smoke during fires, significantly contributing to the safety of building occupants and the effectiveness of firefighting efforts.

The elements of the NRWG system are produced with strict certified factory production control, guaranteeing maximum safety and reliability for our customers. Our production, designed to meet legislative requirements and current fire protection technical guidelines, ensures that our products function effectively under all circumstances.

Hajdu-Alu Zrt. employs the largest systems, using SCHÜCO, ALUPROF, and JANSEN profiles and drives from GEZE and AUMÜLLER to manufacture and install the following products:
