440 SoundBarrier controls sound in floors, walls and ceilings. It 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.
This product should fit on most centerbeam flat cars.
