Abstract
An insulating panel which comprises at least one layer of polystyrene covered on at least one side by a layer of cellulose. Preferably, the cellulose is intermixed with an adhesive and sprayed onto the polystyrene and the adhesive, and upon curing, bonds the cellulose together and to the polystyrene layer; or, alternatively, the cellulose material is molded into a pad or panel which is subsequently bonded to the polystyrene layer. The exposed side of the cellulose layer is in turn covered with a vinyl or other decorative coating to form the insulating panel. The overall insulating panel exhibits a very high R value and thus has a very low coefficient of thermal conductivity.
