Lorient LAS1011 Firtree Acoustic Smoke Seal – Door Edge Push Fit Seal
The Lorient LAS1011 Firtree Seal is a push-fit perimeter seal designed for installation into a machined groove in the edge of a door or frame. It provides acoustic containment and smoke control while maintaining a concealed, low-profile finish.
The seal features a barbed “firtree” spine with dual flexible fins, allowing it to be friction-fitted without adhesives or mechanical fixings. This design enables quick installation and consistent long-term performance in both new and retrofit door applications.
The LAS1011 is commonly used in commercial door assemblies where controlled gaps are required for acoustic performance and compliance with smoke sealing requirements.
