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. Made with FSC® certified material.
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
