Gaps around the four sides of a fire door leaf are essential its the only way the door can open + close. But these gaps create a point of weakness, where fire can take hold + destroy the door, + lethal smoke can pass through.
Lorients intumescent seals protect those gaps. Most of the door seals shown here are multi-functional + provide protection against fire, smoke, sound leakage + heat loss. These seals are used in the top + vertical sides of door leaves, or in the frame. The bottom of the door should be sealed with a threshold seal from our architectural seals range.
