Ultimate Fire Safety Solution

Protect your property with Rockwool High Expansion Intumescent Sealant, exclusively available at PipeLagging.com. This high-performance, water-based acrylic sealant, infused with graphite, delivers robust fire-stopping for pipes, cables, and permanent services. Supplied in 310ml cartridges, it’s perfect for construction and renovation projects prioritizing safety.

Unmatched Fire-Stopping Technology

Designed for service penetrations through compartment walls and floors, this sealant activates at temperatures above 135°C. The graphite expands rapidly, creating a high-pressure seal that blocks flames and smoke for up to 4 hours. It restores the integrity of fire compartments, making it ideal for pipes, cables, and insulated metalwork.
