Fire-Resistant Wall and Door System

Fire-resistant separation of IT systems

High quality surface

Diverse alternatives due to modular design


Wall and door system with glass elements for the fire-resistant separation of IT, power supply and ventilation/fire extinguishing equipment into independent fire zones. The wall and door system is cold and hot smoke-tight and provides fire resistance for 90 minutes. The high-quality interior and exterior surfaces round off the neat appearance of this easily, quickly and cleanly installable and expandable wall system. The 42 mm modular design allows a variety of alternatives to fire-safe ventilation systems, cable/pipe bulkheads, valves and fittings.

PRIOWALL IT+ is trimmed with a low-temperature insulation and provides increased IT protection on the basis of EN 1047-2.
