These acoustic seals are self adhesive and easy to fit to the head and jambs of acoustic / soundproof doors. The can often be used to improve the soundproofing performance of doors fitted with brush seals that have been cut out to fit around locks and hinges etc which substantially weakens the sound insulation performance of the acoustic door.
They need to be fitted to the frame which must be clean, free from grease dust and dirt. They are also very effective when used in conjunction with our surface mounted acoustic door seals as they provide for a second acoustic seal with a small airgap between each acoustic seal. They should bever be overpainted as paint will stop the acoustic fins from working properly.
