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. Lorient’s intumescent seals protect those gaps.
All products are durability tested to 10 times the industry standard.
This slim-line, dual function life safety seal is fitted to door frames to restrict the spread of ambient and elevated temperature smoke. When exposed to fire conditions the intumescent core rapidly expands in volume to restrict the passage of hot smoke and toxic gases.
