ABSTRACT:
A lightweight and resilient heat barrier laminate which provides sound and vibration dampening. The laminate has a density less than about 5 lb/ft.sup.3 and a total thickness of no greater than about 1 inch. The laminate includes a first metal foil having high heat conductivity and a first batt of insulating nonwoven fiber material having a thickness of at least about 0.03 inch. The first batt is an outermost layer of the laminate which is adhesively bonded to a first side of the first metal foil. The laminate also includes a second metal foil and a second batt of insulating nonwoven fiber material different from the material of the first batt. The second batt has a thickness of at least twice as thick as the first batt and is adhesively bonded to a second side of the first metal foil. The second metal foil is an outermost layer of the laminate, has high heat conductivity, is in contact with the second batt of insulating material and can be in contact with a carpet.
