Gaps around the four sides of a fire door leaf are essential as it is the only way the door can open and close. However, 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.

Lorient is a well trusted brand, with fully tested products which are durability tested to 10 times the industry standard. Their products offer cost effective protection against fire, smoke, sound leakage and heat loss.  

All seals are supplied with high performance self-adhesive backing tape.
