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.

The Finesse™ profile is supplied with translucent fins as standard.

A choice of sizes to cover both 30 and 60 minute applications.



Other lengths are available to special order. Lorient can also produce fire seals ranging from 10–70 mm wide and from 2.5–15 mm deep.
