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.
