ATS Acoustical Cotton Batts are an eco-friendly alternative to fiberglass or mineral wool acoustic insulation.  The natural cotton fibers are 100% recyclable and are made from at least 85% post-industrial recycled content, making them ideal for LEED certified projects. ATS Acoustics does not recommend this material for use in applications requiring a fire rating.
This product has a density of 2.5 pounds per cubic feet, with a variance of +/- 0.5 pounds due to the natural fiber.
