for access, ventilation and shielding 

Technical areas are essential for the proper functioning of buildings. The requirements for screening, access and ventilation in a technical room depend on the function. For a room with a gas installation, a completely different design is required than for a transformer room or a server room.

Because we develop, produce and assemble ourselves, we stand for safety, continuity and sustainability. With our products and extensive expertise in the field of fire safety and burglary resistance, we guarantee processes and functionalities of high-quality installations. So that energy actually produces energy.
