Fire, medium & hot temperature smoke 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. Lorient’s intumescent seals protect those gaps.

All products are durability tested to 10 times the industry standard.
