The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a - radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced.
