Firebreak - Fire Safety by Design

Firebreak 66 Intumescent Pressure Sealant

Firebreak 66 is a flexible intumescent sealant especially formulated to provide excellent fire resistance and high levels of expansion and pressure, especially when used to seal around and close down small combustible plastic pipes in fire situations.


Firebreak 66 is a one part, water-based high pressure intumescent sealant which in fire conditions expands to seal openings in fire compartment walls and floors where these are penetrated by plastic pipes, metal pipes with combustible insulation and electric cables.
