Lorient

Lorient is the UK's leading specialist manufacturer of sealing systems for door assemblies, covering fire protection, smoke control, acoustic insulation, and weather exclusion. Gaps around the four sides of a fire door leaf are essential for operation — but they create a point of weakness where fire and lethal smoke can pass through. Lorient's intumescent seals protect those gaps, expanding under heat to maintain the integrity of the fire doorset.

Lorient products are specified by architects, fire door manufacturers, and compliance consultants wherever the performance of fire and smoke separation must be independently verified. We stock intumescent fire seals for 30 and 60 minute applications, combined fire, smoke, and acoustic seals, automatic drop seals, perimeter seals, and threshold seals.
