Tenmat Fire Rated Cavity Barrier Roll 65mm is a flexible intumescent solution for ventilated cavities behind masonry or brickwork façades. Designed to maintain airflow during normal conditions, the roll rapidly expands to seal off cavities in the event of fire—delivering 60 minutes of fire integrity and insulation.

Its ultra-thin 6mm profile offers an alternative to traditional cavity socks, saving both space and labour. Supplied in a 6.3m roll and covered with protective polythene for easy handling, it fits cavities up to 65mm, accommodating building tolerances up to 15mm. The CavGuard Roll 65 is ideal for uninsulated cavities requiring both ventilation and passive fire protection.

Trusted Passive Fire Performance


CavGuard Roll 65 by Tenmat is engineered for high-integrity fire stopping in external cavity walls. Its intumescent core activates during fire, expanding to seal off the air gap and limit spread through ventilated cavities.
The roll’s 6mm design allows for continuous ventilation where required and is compatible with uninsulated brick or masonry walls. It reduces the need for cavity trays or weepholes, cutting down build time and complexity.

Designed for Flexible Fit


With a roll length of 6.3m, CavGuard Roll 65 is easy to trim and install. It adapts to site tolerances up to 15mm beyond the standard 50mm cavity, making it suitable for varied construction needs without sacrificing safety.

Easy to Handle and Install


Lightweight and flexible, it can be fitted quickly with minimal tools. The polythene layer ensures safe handling and protects the product before activation. Once in place, no maintenance is needed, making it a cost-efficient solution.

Built for Ventilated Façades


CavGuard Roll 65 supports the airflow needed in ventilated façades, preserving energy performance and minimising the risk of trapped moisture. In case of fire, it seals the cavity while preserving structure for up to 60 minutes.

Backed by Proven Fire Testing


Certified to deliver up to 60 minutes of insulation and integrity, Tenmat’s CavGuard Roll 65 meets the passive fire safety standards required for modern construction. Refer to the manufacturer brochure for full testing data.
