A 19.7 x 78.7 in roll of sound deadening and heat insulation material: aluminum foil facing over a dense rubber-cotton layer. It is meant to cut engine noise, exhaust hum and road vibration and to shield against heat, and it can be cut to fit doors, floors, roofs, hoods, firewalls and trunks. It is a generic, universal roll rather than a vehicle-specific kit, so fit depends on how you cut and place it. Compared with branded butyl mats, it is a lighter foil-and-foam style that leans toward thermal blocking and easy contouring rather than maximum mass loading.
