Abstract: Building walls and ceilings, beam or column covers, hollow columns, column covers, soffits, ducts, duct covers and solid construction posts fabricated from V-grooved gypsum board construction members which are adhesively secured in the V-groove areas to form angular faces. Interior and exterior walls using such construction members in combination with panel clips provide structures which are readily disassembled and reusable while providing good sound and thermal insulation properties.
