DURAFIRE® DD 240 SLIDER
The DURAFIRE® DD 240 Slider has its principal application
as movable sections of a DURASTEEL® fire protection
system. The DURAFIRE® DD 240 Sliders are certified to
BS 476: Part 22: 1987 for up to 240 minutes integrity and
are ideally suited to medium and heavy duty industrial
situations in power generation and industrial buildings.
One of the main benefits of these sliding doors is that they
can be produced to much larger dimensions than
conventional hinged doorsets, offering access to large
plant and machinery etc, whilst retaining the specified fire
performance of the compartment wall. These doorsets can
be designed to incorporate a wicket door for personnel
access. The unique design of the DURAFIRE® DD 240
slider enables manufacture of a variety of configurations for
both horizontal and vertical sliding in single and double leaf
constructions.
