KINETICS® Sound-Rated Acoustical Doors & Perimeter Gaskets


Room isolation designs are only as good as their weakest link, and residential doors present several challenges that can be met with Kinetics’ line of wood acoustical doors. First, the door itself, if not well-constructed, will transmit sound energy from one room to another. Second, air gaps around the perimeter of the door, if not sealed, are easy pathways for sound to transfer to adjacent spaces. Additionally, most sound-rated doors are made of metal and are not attractive in residential environments.

Kinetics offers custom-manufactured STC-49 and STC-35 sound-rated acoustical doors which have been specifically designed for residential environments and offer a wide variety of standard and custom wood finishes, sizes, and acoustical seals.



  • Improves the integrity of isolated room design
  • Available with jambs (pre-hung) or as slab-only
  • Sound-rated gaskets,in a wide variety of options, are available to effectively seal air-gaps between the door and frame.
  • Custom manufactured to your project
