- Fi-Block™ is a passive intumescent fire protection product designed to seal fire wall penetrations so ensuring the fire rating of the building partition is maintained.
- Fi-Block™ is approved to be used in conjunction with Thermobreak® Tube Insulation for Dry Wall, Rigid Wall and Rigid Floor penetrations. The intumescent expands (up to 30 times), slowly replacing the space occupied by the insulation, producing a solid compact material which inhibits further progress of the fire through the wall cavity.
- Tested and Certified to AS 4072.1, BS476.20, and EN1366.3
- Provides a fire resistant barrier for up to 4 hours depending on application
- Environmentally Safe – halogen and fibre free
- Easily installed over in-situ piping by one person
