Acoustiblok Soundproofing Material – Acoustiblok is the name of both our company and our “Flagship” product. This product is used as a sound isolation material. It is typically installed before walls, ceilings and floors have been completed, thereby enhancing the Transmission Loss (TL) of these standard assemblies. These sheets are then trimmed to a standard size of 54” wide x 30’ long and rolled up for easy transportation.
