A pad including thermal insulation and heat sink areas. The pad includes a plurality of layers of metal foil forming a stack with the layers arranged one above the other, the stack including at least one heat sink area and at least one insulating area adjacent to the heat sink area, the layers providing better heat conduction in the vertical direction at the heat sink area than at the insulating area. At least one of the layers includes a plurality of embossments therein separating the one layer from an adjacent one of the layers in the insulating area. The pad can include a single insulating area surrounded by a heat sink area and a black coating can be provided on selected portions of the layers to improve heat radiating characteristics of the pad. For instance, the heat sink area can be coated with the black coating to radiate heat away from the pad at a desired location. The pad is particularly useful in shielding a heat sensitive component on one side of the pad from a heat source on the other side of the pad. The pad can be covered with a prescored and/or embossed metal sheet coated on one or both sides with adhesive. The sheet can also be used by itself for fixturing. The sheet can be secured to an object by heating to cause the adhesive to adhere to the object. The prescoring can be perforations in the sheet and the embossments can be in a diamond shaped cross-hatching configuration.

Pad including heat sink and thermal insulation area

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.
