The Lorient Batwing® provides the solution to the requirements of all three Approved Documents, in one easy-to-fit product. With a proven smoke performance from ambient even up to 200°C, the Batwing® is an ideal choice for upgrading fire rated doors to provide additional smoke protection - or, it can equally be fitted to new fire rated door assemblies alongside one of our fireseals. The Lorient Batwing® is also covered by extensive acoustic test evidence. And now that the fins are subtly curved to work with the door leaf, the seal provides minimal frictional resistance, so the door remains easy to operate, contributing to Document M requirements.
