NW115 F Fire Resisting Wall
Alco Beldan 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 60 minutes with class A2 (non-flammable) cladding boards.
This was also tested with B2 (normal) cladding boards and achieved 30 minutes.
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 Beldan NW115F has been tested in accordance with DIN EN 1364-1 classification and General Building Control Test Certificates have been issued for 30 minutes and 60 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.

There is no reason specifiers should be put off insisting on inspecting a copy of the test data as vague covering statements such as “testing in accordance with DIN 4102 F30 quality” or “F30 A/B flammability” means nothing.
