For superior acoustic qualities, improved STC and NRC, WallWool outperforms fiberglass for interior wall sound absorption and isolation. WallWool is made from ceramic fiber and contains none of the glue or formaldihyde found in fiberglass.

ASC WallWool Batting has been formulated to provide maximum sound attenuation in a relatively thin package. There is no fiberglass resin adhesive in this material and no odor. It combines refractory wool that has twice the acoustic efficiency of acoustic fiberglass panels with an acoustically transparent envelope. The result is that the highly fibrous, non-asbestos sound absorbing material is contained in an easy to apply insulation batting.

WallWool is 1" thick and comes in 16" or 24" widths, custom lengths up to 10'. Due to the lack of binder glue, we encase the product in a Tyvek type of material. It can be ordered one sided, two sided or without any backing depending on your special needs.
