High Performance DS Acoustic, Smoke and Fire Seal

Three seals in one - Lorient's complete solution for acoustic, smoke, fire and thermal containment, and accessibility, to meet the requirements of Approved Documents B, E and M.

With elastomeric fins on both edges of the seal, the DS is designed to ensure continuous sealing at ironmongery points - essential for effective smoke and acoustic containment. The DS is supplied with black fins, and is available in a range of standard colours - to blend or contrast with surroundings as required.

Proven acoustic performance of 31 dB Rw (when tested in accordance with BS EN ISO 140-3: 1995, on a typical fire rated door construction, installed with LAS8001 si automatic threshold seal). Please refer to the door manufacturers’ fire test evidence to select the correct seal size and combination.
