Acoustic Door Seal Kit
Call for Price
Acoustic Door Seal Kit includes jamb seals, a threshold seal and an automatic door bottom to acoustically seal a 36″ x 84″ door. Unsealed gaps and clearances in door assemblies effectively cancel out the soundproofing benefits of the highest-rated acoustical doors. You can use these acoustic door seal kits on a range of wood or metal doors to reinforce the STC (Sound Transmission Loss) of the existing doors and walls.
A 1% opening around a door will allow up to 50% of the sound energy 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 Seal Kits close off these clearances or openings.
Each Acoustic Door Seal Kit includes 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, our Acoustic Door Seal Kits include high-grade neoprene door jamb seals for the vertical sides and top of the door and a threshold.
You can field cut these door jambs to shorter lengths to fit smaller doors. You can also trim the automatic door bottom, but cuts should not be closer than 1″ to the set screw. Thresholds are field cut to fit between existing door jamb.
