Homasote makes structural, noise-deadening sub-floor/insulating carpet underlayment and sound protection systems that work with virtually any flooring system, from carpet to concrete. Homasote products combine strength, sound-deadening and resilient qualities with twice the insulation of wood.

Far lighter than concrete, Homasote does not require additional joists or supports, for savings in material cost, time and labor. The result is a tight, permanent method of sound control.
