Description

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.

Four different seals available:

10 x 4 mm Ref: LP1004DS:

Can provide up to 30 minutes fire resistance. Two parallel seals (in separate grooves) can provide 60 minutes fire resistance in hardwood constructions.

15 x 4 mm Ref: LP1504DS:

20 x 4 mm Ref: LP2004DS:
