Description

The Lorient Batwing® smoke and acoustic perimeter seal minimizes the opening and closing resistance of the door leaf due to its unique, curved elastomeric fins, which provide ongoing performance and durability in service. Doors are easier to open, contributing to Document M requirements, without losing any of the benefits of smoke protection up to 200°C, and Document E acoustic containment.

Tested for acoustic performance in accordance with BS EN 1634-1: 2000. Proven acoustic performance of 31dB Rw, when used on a typical architectural solid core door, with the LAS8001 si drop seal. Acoustic performance of 37dB Rw attained on a specialist high performance acoustic door (with the LAS8001 si).

Tested for smoke performance in accordance with BS 476-31.1: 1983 at ambient temperatures; BS EN 1634-3: 2004 at ambient and medium temperatures (LAS1212); effective smoke seal up to 200°C.

Batwing® is now available in a clear option, which perfectly complements the natural features of a doorset, without compromising on aesthetics.
