Abstract: A heat and sound insulating panel assembly for wall, ceiling or floor construction consists of a plurality of interlocking vacuum-chambered panel elements fabricated from a relatively hard, low thermally-conductive, fire-resistant or fireproof material with heat-reflective, moisture-restraining coatings on its inner and outer surfaces. Abutting surfaces may be provided with sound-cushioning pads, and vacuum-chambered spacer column elements may be employed, interlocked between panel elements, for uniform increased panel wall thickness.

Abstract: A geometric image comprising both a nonreflective material and a metalized plastic film capable of dispersing visible light into its component colors, which colors may change relative to the angle of the light being dispersed and reflected back to the viewer.
