This high-performance, water-based acrylic sealant is expertly formulated with graphite to provide robust fire-stopping capabilities for a variety of building penetrations. Ideal for both combustible and non-combustible pipes, as well as cables and other permanent services, this sealant ensures your property remains protected against the spread of fire and smoke. Supplied in convenient 310ml cartridges, it’s a must-have for any construction or renovation project prioritizing safety and efficiency.

Unmatched Fire-Stopping Technology

The Rockwool High Expansion Intumescent Sealant is designed to tackle the challenges of fire protection where service lines pass through compartment walls and floors. When exposed to temperatures above 135°C, the graphite within the sealant activates, expanding rapidly to create a high-volume, pressure-resistant seal. This effectively closes off voids left by combustible materials, preventing the passage of flames and smoke for up to 4 hours. Whether you’re sealing around pipes, cables, or insulated metalwork, this product reinstates the integrity and insulation rating of your fire compartments with ease.
