Architectural acoustic seals
We are pleased to offer a range of acoustic seals, widely used in the manufacture and installation of architectural door assemblies.
Note: For effective acoustic performance, a door assembly must be comprehensively sealed around the entire perimeter, including the threshold. Products offered by Millmerran have been specially selected to harmoniously combine the essential “Drop-down” seal at the threshold with high performance options around the rest of the perimeter.
