ABSTRACT:
A unitary structural panel for ceiling and wall installations has a dimensional stability and structural strength to be edge supported as a unit without sagging or warping, a high impact resistance, a good fire rating and easy washability. It comprises a relatively thick fabricated panel which of itself may be subject to sagging or warping or impact damage or fire damage or soil damage, and a relatively thin and flexible laminated facing for the fabricated panel. The thin and flexible laminated facing includes a metallic film, a glass fiber scrim and a synthetic plastic film adhesively secured together with the scrim between and bonded to the metallic film and the synthetic plastic film and with the metallic film bonded to the synthetic plastic film within the openings in the scrim. The laminated facing is adhesively secured to the fabricated panel with the metallic film thereof bonded to a face of the fabricated panel and with the synthetic plastic film thereof exposed.
