Our intumescent putty is non-setting which enables a fair bit of movement and the ability to remove and re-use. Putty is ideal for sealing pipes, cables and service penetrations , especially ones with odd shapes.

Each 1 litre tub of intumescent putty can give up to 4 hours of fire resistance - depending on how deep the coverage - and has been tested to BS476: Part 20: 1987 and EN1366-3 and Certifire approved. It is resistant to moisture and fungus and even provides acoustic isolation to EN 10140 to 65 decibels.
