For over twenty years, Lorient has specialized in the design and manufacture of fire, smoke and acoustic sealing systems for door assemblies to meet international standards. throughout this period, Lorient has introduced major advances in the technology of these performance door designs, developing a unique understanding and expertise, particularly in the field of intumescent materials.

Intumescent materials are complex chemical substances which expand vigorously on exposure to intense heat, forming an insulating cellular structure with immense stability and resistance to fire penetration.

These materials are incorporated into many of Lorient's products enabling them to provide comprehensive protection against the break-through of flames, hot gases, smoke and toxic fumes.

These hazards may be encountered over a wide temperature range in any given fire situation and the introduction of 'positive pressure' fire testing in the USA now recognizes this.

Lorient sealing systems provide impressive benefits for building occupants in terms of life safety and also provide outstanding protection for the building contents, particularly if they are vulnerable to smoke damage.
