MULTI-PURPOSE BOX
DESCRIPTION
Envirograf® multi-purpose boxes comprise a box section containing intumescent material, with a section that can be removed to allow the unit to be used in tight corners, to fit over existing services. The fixing brackets are adjustable by bending them flat, for fitting into corners or for when the box is flush against the ceiling, floor, or wall. A fire-resistant sponge smoke seal is supplied with each unit. This can be cut easily with a knife, allowing services to pass through the unit, but sealing the gaps against smoke penetration, so the underlying hole in the floor or wall can remain open.
USE
The Envirograf® multi-purpose box is the most versatile of its kind available and has been specifically designed for most installation requirements where services pass through fire barrier ceilings, floors, and walls. It can be surface-mounted or recessed.
PERFORMANCE
The multi-purpose box was tested to BS476 Parts 20 and 22 (1987), achieving up to 4 hours of fire protection. Also tested at VNE to European Standard EN1363-1 (2000).
