Asphaltic mastic sound deadener is similar to OE material that came on most vehicles from this era. This die cut, 1/8" thick matting is applied directly to the cab floor to reduce noise and insulate against heat and cold. This acoustic noise barrier consists of a black paper impregnated with an asphaltic mastic material. It is easy to install and can work in conjunction with other sound and thermal insulating products.
