Lorient Intumescent Sealant is a versatile seal solution to fill gaps and movement joints; and for use where rigid seals are impractical.

 

When exposed to fire, Lorient Intumescent Sealant

expands in volume to fill all cavities; providing a

necessary hot smoke seal.

It is suitable for sealing gaps between fire resistant

walls and floors, between conduits and walls/floors

and between fire resistant walls and structural

supports. Lorient Intumescent sealant is also

recommended for sealing the perimeter of fire and

smoke resistant damper/air transfer grilles.
