About Acoustical Door Seals
Acoustical Door Seals
Unsealed gaps and clearances in door assemblies effectively cancel out the noise reduction benefits of the highest-rated acoustical doors. A 1% opening around a door will allow up to 50% of the sound to pass through that opening. Consider this, a 1/8" opening around all four sides of a door will reduce the effective rating of an STC 52 door down to an STC 21 -- guaranteeing very poor acoustical performance.
Our acoustical door seals close off these clearances or openings. They include an automatic door bottom, which is spring operated, dropping a neoprene seal onto a threshold and effectively sealing off the bottom of the door. In addition to that, we offer high-grade neoprene door jams for the vertical sides and top of the door. Packaged door seal kits are also available.
