440 SOUNDBARRIER®

440 SoundBarrier® controls sound in floors, walls and ceilings.

Independently lab tested and time-proven in millions of square feet of residential and commercial structures, 440 SoundBarrier® is a special-density, structural board made from 100 percent environmental Homasote® cellulose fiber, a homogeneous composition manufactured with uniformly distributed protection against termites, rot and fungi and resistance to moisture. It also insulates, with twice the R-value of wood.
Carpenters and do-it-yourselfers can easily install 440 SoundBarrier® in room partitions and peripheral walls, ceilings and floors, in:
  • single or multi-family housing
  • high and low-rise apartments and condominiums
  • motels
  • schools
  • professional buildings
  • assisted living facilities
