    Noise Ratings

    STC 49 KWAD-49 Provides superior performance for critical room isolation designs
    STC 35 KWAD-35 Provides a cost-effective improvement over typical residential doors
    STC 15-20 Typical residential doors



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


    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. Finally, production lead-times can be extremely long and therefore unacceptable to the construction schedule.

    Kinetics offers custom-manufactured STC-49 and STC-35 soundrated acoustical doors with improved lead times for production and the ultimate in design flexibility. Kinetics’ acoustical doors have been specifically designed for residential environments and offer a wide variety of standard and custom wood finishes, sizes, and acoustical seals.

    Full test reports available upon request

    Kinetics acoustical wood doors are made with lab-tested noise control core materials and are finished in a variety of high-quality woods.

    Kinetics acoustical doors include a standard set of sound-rated gaskets that consist of head/jamb seals (for sides and top) and sweeps (for door bottoms).
