Fire Rated Expanding Foam
A polyurethane foam that emits virtually no fumes or gases when affected by flame. The can contains
2 liquids, which mix when leaving the can and expand by absorbing moisture from the air. It expands
up to 40 times its original volume on application. Supplied in 750ml environmentally-friendly aerosol
spray can (PVE/A) for application by tube. It can also be supplied in a 750ml screw-top can (PVE/A/G)
for use with industrial trigger gun (PVE/A/IG). A red identification coating and labels are available on
request, to show building control and fire officers it is our fire-tested foam. In order to maximise the
yield of each can, Envirograf® solvent cleaner (PVE/A/S) is essential to clean tubes and nozzles for
re-use and for cleaning up any spillage in the application area.

For filling around awkward openings, around services, and behind door frames (without taking off architraves)
and behind window frames. For fire sealing of services passing through the foam, use
Envirograf® Product 110. Use Envirograf® solvent cleaner to clean the application tube (and
spills) immediately after use, saving the foam remaining in the can. Can be painted over.
