Similar to the ASP single fin seal the ASPTF Twin Fin seal is a compact design ideal for hygiene and clean rooms and removes the need to fit separate smoke and acoustic seals. Engineered to size to avoid overlapping door ironmongery with excellent compression and deflection performance and allows reduced door closing force due to a low coefficient material used in integral fins. 


Acoustically and smoke tested on proprietary fire doors. Noise Reduction Index Rw 35dB*. Suitable for new and retrofit applications the seals are quick and easy to apply. The ASP TF seal is manufactured from co-extruded rigid and flexible flame retardant PVC, complete with an aggressive self adhesive backing tape.


For full acoustic and smoke sealing the Acoustic & Smoke Perimeter seal should be used in conjunction with an acoustic rated door bottom seal and, where required, a disabled access threshold plate.


Smoke Testing was conducted to BS EN 1634-3: 2004 smoke control tests for door and shutter assemblies, openable windows and elements of building hardware – Part 3: Smoke control test for door and shutter assemblies.
