Info
The GTEC Vapour Board is a GTEC Standard Board enhanced with an additional laminated vapor control layer. It shares the same physical properties as the standard board but features a silver metallised polyester film back liner, which significantly improves its vapor resistance. GTEC Vapour can be jointed and finished using GTEC Jointing Systems and must be primed with GTEC Universal Sealer before decorating.
