Acoustical Door Seals are a critical part of every soundproofing project. Sound leaks from windows and doors are some of the largest problems when creating a sound controlled environment.

Unsealed gaps and clearances in door assemblies effectively cancel out the soundproofing qualities 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 gaskets close off these clearances or openings. Our acoustical door seals 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 jambs for the vertical sides and top of the door. Packaged door seal kits are also available. These acoustical door gaskets can be retrofitted to an existing door or applied to a new door.
