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 materials are available in white or black and if appearance is important to you, we can work with you on the color of the facing material. Since Sonic-Fiber Faced Mineral Wool is generally used as a component of an enclosure, an acoustical panel the color of the facing material generally does not matter. However, a foil facing is available and we can speak with you about the need for that particular “flavor” of Sonic-Fiber

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.
