Sonic Fiber Faced Mineral Wool
Sonic Fiber Faced Mineral Wool is a semi-flexible non-asbestos mineral wool that provides greater sound attenuation than fiberglass bats or urethane foam. Sonic Fiber Faced Mineral Wool is naturally hydrophobic (repels water), fire resistant, does not promote mold growth, and is vermin-proof. (yes vermin proof - we are not kidding - if it wasn’t important, we wouldn’t bring it up!)
It is available in sheets that are faced on one side with an encapsulant which protects the fibers and acts like a vapor barrier. The facing material is available in black.
The Noise Reduction Coefficient (NRC) of a material is obtained through testing by a certified laboratory to ASTM standards. The NRC is an indication of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection (such as a smooth concrete surface) and an NRC of 1 indicates perfect absorption. Sonic Fiber Faced Mineral Wool is used inside rooms, enclosures and walls to reduce acoustical reflections and sound energy, is used with sound barrier materials, such as Sonic-Shield® Noise Barrier.
