The ArtBA acoustical blanket absorbs and blocks noise reducing noise levels without requiring extra building construction. The ArtBA acoustical blanket consists of a fiberglass core quilted between vinyl-coated-fiberglass-cloth facings which is then attached to a reinforced mass loaded vinyl barrier. Rolls measuring 4' x 25' are available and have a Class A flammability rating. Because of their excellent durability these curtains are perfect for industrial locations, manufacturing facilities, construction sites or anywhere requiring abuse resistant noise control. These double duty noise blankets excel in that they work for both absorbing and blocking sound.
