As a prominent figure in the market, ROCKWOOL provides a user-friendly retrofit solution in the form of this intumescent expansion joint seal. It functions as an effective firestop for construction joints measuring up to 75mm thick in walls and floors and is a versatile option. It has also undergone rigorous BS476: Part 20 testing, verifying its capacity to deliver up to four hours of fire protection.
The low-maintenance nature of this solution is due to its compressible design, fashioned by shrink wrapping each face of a ROCKWOOL core with a graphite-based intumescent polymer. You can easily compress the length required by hand and insert it into the joint without resorting to adhesives or intumescent sealant. In the event of a fire, the innovative composition of this product allows it to swell and create a tough char that effectively impedes the passage of flames and smoke through the joint.
Crafted with water resistance, this ROCKWOOL intumescent expansion joint seal is suitable for use in blockwork cavities, structural and expansion joints, and curtain wall interfaces. By following the manufacturer's instructions when installing this solution, you can rest assured that it provides unparalleled fire protection.
