This PU expanding Fire Door Foam™ has been designed and tested to seal those important gaps between walls and fire door frames, achieving up to 60 minutes of fire protection.

It’s easy to apply, taking around 3 minutes on every door set installed, and replaces the need for mineral fibre wool and mastic. It’s also the most certified fire door foam on the market, which has been specifically tested on fire door assemblies.

The pigment has recently been changed to orange to distinguish it from generic pink fire foams that are common on the market and untested to work within fire door assemblies.
