Intumescent Products 

Intumescent Seals 

Gaps around the four sides of a fire door leaf are essential – it’s the only way the door can open and close. 
But these gaps create a point of weakness, where fire can take hold and destroy the door, and lethal smoke can pass through. In everyday use, sound can also pass through unprotected gaps; and the building’s heat can be lost, wasting energy. 
Intumescent seals protect those gaps. Most door seals are multi-functional, which means just one product offers efficient, cost-effective protection against fire, smoke, sound leakage and heat loss. 
These seals are used in the top and vertical sides of door leaves, or in the frame. The bottom of the door should be sealed with a threshold seal. 
All products are durability tested to 10 times the industry standard. 
Fire seals and smoke seals can be fitted separately if preferred. A smoke, acoustic and thermal seal can be added to upgrade a fire door, or protect a non-fire rated door. 

Intumescent Sealant 

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, the Intumescent Sealant expands in volume to fill all cavities; providing a necessary hot smoke seal. 
Suitable for sealing gaps between fire resistant walls and floors, between conduits and walls/floors and between fire resistant walls and structural supports. 
Suitable for sealing the perimeter of fire and smoke resistant damper/air transfer grilles.
