AP foil faced foam was intended to be used in applications where it would be covered with a wall covering. Because the intended use of the product does not include exposed applications, this product has not been tested for acoustic absorption. Additionally, this product would not be expected to increase the Sound Transmission Class (STC) of a wall assembly due to its light weight.
