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.
