Thermal Fire Pipe Sleeve range

A cost effective product for fire stopping pipe penetrations, eg. plastic and metallic plumbing.

Maintains similar thermal and acoustic properties as standard mineral fibre insulation to ensure compliance with water bye laws and building regulations for cold and hot water pipes and heating systems.

In a fire the pipe sleeve sleeve expands to fill the available space between the pipe and the penetration.

In the case of a plastic pipe the sleeve will crush and close off the pipe as it forms a solid char, preventing the passage of fire and smoke.
