Acoustic, Smoke + Fire Door Seals

Gaps around the four sides of a fire door leaf are essential – it’s the only way the door can open & close. But these gaps create a point of weakness, where fire can take hold & destroy the door, and lethal smoke can pass through.

Lorient’s intumescent seals protect those gaps. Most of the door seals shown in this section 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.
