NW115 F Fire Resisting Wall

Alco Walls NW115 F Fire Resisting Wall

Our type NW115 F is a movable partition wall which has been tested in accordance with DIN 4102-T2 and achieved 30 minutes with class B2 (non-flammable) cladding boards.

The same construction was also tested for sound reduction and achieved ratings up to Rw 54dB in accordance with EN 20140-3 (1995). This type NW115F is also smoke resistant to DIN 18095-2

The Alco Walls NW115F has been tested in accordance with DIN EN 1364-1 classification and General Building Control Test Certificates have been issued for 30 minutes fire resistance.

The sample tested included several inter-panel joints, grooves, fixings, wall posts etc. This is therefore a fully movable partition wall which when fully closed and locked in position, achieved the same fire resistance as a fixed wall.

The NW115 F movable wall system meets the requirements of the Building Regulations and currently represents the best movable partition wall for the protection of escapes and rescue routes.
