ABSTRACT:
A rigid building component such as a door, table top or the like, is formed of coarse wooden particles mixed with adhesive, and a solid wooden edge frame, positioned between a pair of damp, substantially parallel, cellulosic fiber webs. A heated press is employed to compact the combination, particularly between the edge frame and the cellulosic fiber webs where the coarse wooden particles are greatly compressed to provide a durable edge. Under the heat and pressure applied in the press the particles are consolidated into a solid structure, while the damp cellulosic fiber webs are converted to tough exterior skins bonded to the coarse wooden particles. The sides of the rigid building component are suitably deeply embossed to provide a decorative paneled appearance.
