Fire-Resistant Room

For the basic protection of your network systems

Room-in-Room alternative

Modular design of the system 42


Fire-resistance room for the basic protection of IT, communication, and network systems. With just 42 mm panel thickness, the room offers space-saving room-in-room alternatives to conventional interior work of solid construction.
The benefits: Can be quickly and cleanly installed, expanded, and retrofitted during ongoing opera-tion. The PRIORIT 42 mm system’s modular construction allows multiple alternatives with fire- and smoke-protected ventilation systems, valves, and fittings. The room offers 90 min. of fire re-sistance.

PRIOROOM IT+ is lined inside with low-temperature insulation and provides increased IT protection based on EN 1047-2.
