ROCKWOOL Intumescent Expansion Joint Seal 1000 X 15 X 25mm (6 Pieces)

ROCKWOOL, a leading player in the market, offers a straightforward retrofit solution with this intumescent expansion joint seal. It serves as a highly effective firestop for construction joints up to 75mm thick in walls and floors. This adaptable option has undergone rigorous testing according to BS476: Part 20, which confirms its ability to provide fire protection for up to four hours.

This low-maintenance alternative features a compressible design created by shrink wrapping a graphite-based intumescent polymer to the faces of a ROCKWOOL core. Once you manually compress the desired length, you can insert it into the joint without the use of adhesives or intumescent sealant. In the event of a fire, the unique composition of this product causes it to swell and expand, forming a durable char that prevents flames and smoke from passing through the joint.
