Rockwool 128086 High Exp Intumescent Sealant 310ml Grey

Rockwool High Expansion Intumescent Sealant

Service lines can often present a challenge when it comes to fire stopping where they pass through compartment walls and floors, as they are often installed towards the end of a site programme and can compromise existing firestopping. The High Expansion Intumescent Sealant solves this problem. An easy to use sealant, this product is ideal for protecting both combustible and non-combustible pipes, among other permanent services.

Rockwool High Expansion Intumescent Sealant is a water-based acrylic sealant containing graphite, making it the perfect solution to sealing various penetrations.  Fire stopping of combustible services is ensured once the sealant reaches temperatures of 135°C and above, where it will expand and close any voids formed, to stop the passage of smoke and fire.

Not only does this product have flexible use but is suitable for a range of materials.  Approved for use on LUL surface and sub-surface premises having been tested and achieves low smoke and toxicity.
