Laminate Tape

November 7, 2006

A method of insulating a component of a heating, ventilation and air conditioning unit was patented. The component comprises a metallic substrate having an outer surface and another surface that is in contact with a hot or cold gas or liquid. The method comprises two steps, the first of which is providing a laminate tape comprised of: a) a tacky first layer made of asphalt, rubber and particulate cork filler and having a thickness of from about 0.05 inches to about 0.25 inches and b) a second layer that is essentially non-tacky and comprised of rubber. The second layer has a thickness of from about 0.02 inches to about 0.15 inches and is no greater in thickness than the tacky first layer. One side of the tacky first layer is adhered to one side of the second layer. The width of the second layer is from about 100% to about 120% the width of the tacky first layer. The tacky first layer and the second layer each have a width of from about 1.5 inches to about 3.5 inches. The second step is pressing the tacky first layer of the laminate tape against the outer surface of the metallic substrate to conform and adhere the laminate tape to the outer surface.
