Glasroc® H

Glasroc® H has high resistance to moisture and mould thanks to its pre-coated glass mats on the board surface instead of paper liners normally used on plasterboards.

The gypsum core provides water resistant properties while the light blue pre-primed surface repels water to protect the construction. This also provides an optimum surface for direct tiling or smooth decoration.

Glasroc® H gypsum wallboard is perfect for outdoor humid environmental conditions as well as indoor commercial or residential applications that require water rated assemblies.
