Batwing® - it's all about ME ME ME!

Recent revisions of Approved Documents M and E , to the Building Regulations England and Wales have put more demands than ever on doors.

Lorient's Batwing® acoustic and smoke perimeter seal minimises the opening and closing resistance of the door leaf due to its unique, elastomeric curved fins - Approved Document M. Batwing® offers a proven acoustic performance to meet the requirements of Approved Document E, when used with a recommended threshold seal. Tested for durability, the seal has completed 1 million open/close cycles on a full-size door assembly without degradation.

Combine the Batwing® with other Lorient fire sealing products to meet all three Approved Documents M, E and B.
