In the event of a fire, the cover plate of a socket, switch
or light fitting may sag and disintegrate, leaving a
perfect escape route for a fire to travel up the cavity,
into an adjoining room or ceiling. When Envirograf®
pads are fitted, they will expand in the presence of heat
and create an effective fire barrier. This solution has
been specifically designed to help electrical contractors
and building design professionals meet and comply
with the current regulations.
Fire Protection is also available for other Marshall-Tufflex
product ranges. Wraps can be supplied around PVC-U
trunking or conduit systems and pillows to fill a trunking
void. Many different shapes, sizes and thicknesses are
available so for further details please contact our
Technical Hotline on 01424 856688.

With pads
Marshall-Tufflex dry lining boxes are available with
Envirograf® intumescent (fire barrier) pads.
With fire barrier pads fitted, boxes comply with the
requirements of BS7671:2008 IEE Wiring Regulations
and Document B of the UK Building Regulations.
