Soundproofing a room starts with eliminating air gaps around the door, and our highly-effective and affordable Door Seal Kit features an automatic bottom seal and adjustable jamb seals, which create an airtight seal around your door.


  • Reduces sound transmission through door assemblies
  • Cost-effective
  • Easy to install
  • Durable

The self-leveling bottom seal automatically lowers and levels a heavy-duty neoprene gasket to the wood or metal door threshold when closed. Easily installed on any solid-core door, the Door Seal Kit is the most economical solution to sound leakage around a door.
