Fitting SureCav25 with a Cavity Fire-Stop Barrier

There are a great variety of fire-stop
barriers in use, both in timber-frame and
traditional block inner leaf construction.

Trim the SureCav panel horizontally
or vertically to meet the fire-stop
material. All wall-ties and fire-stops
must meet the approval of the
structural engineer/Building Control
The intumescent barrier shown below must be placed so as not to interfere with the SureCav
pods, either horizontally or vertically, depending on the protection required.
If there is a problem with the pods touching the fire barrier then just shorten a length of
SureCav and insert another section to keep a clearance for the intumescent strip (as illustrated
below, approx. 4mm deep to allow a continuous air flow in the cavity in normal conditions.

Always check
carefully the specific
requirements from
your designer and
regulations from your
Local Building Control
for your construction
project.
