ROCKWOOL FirePro PWRoll Intumescent Pipe Wrap - 25m x 40mm

The FirePro PWRoll is a high-performance, graphite-based intumescent wrap designed to reinstate the fire resistance of flexible walls, rigid walls, and floors penetrated by combustible pipe services. By automatically sealing service penetration apertures around plastic and insulated pipes, it effectively prevents the spread of fire and smoke between building compartments.

• Eliminate exact-sizing delays: Instead of stocking specific wrap sizes for every job, this 25m continuous roll allows you to cut custom-fit seals on-site for pipe outer diameters from 40mm to 160mm.
• Guarantee rapid sealing: The graphite compound activates under heat to expand up to 25 times its volume, exerting high pressure to completely crush softening plastic pipes.
• Streamline installation: The wrap requires no mechanical fixings and is secured simply with adhesive tape, saving labor time across multiple penetration seals.
• Adapt to diverse materials: Provides a compliant, ready-to-hand solution for varying pipe materials on-site, including PVC, PP, PE, and MLCP.

This system achieves up to EI 240 fire resistance and is extensively tested to the latest BS EN 1366-3:2021+A1:2024 standard, ensuring your penetration seals meet rigorous compliance demands. It is suitable for use in standard plasterboard partitions, masonry walls, and concrete floors. Classification is verified to BS EN 13501-2:2023, giving you documented assurance for critical safety inspections.
