Glasroc® H (Hydro) is a high-performance gypsum board with a water-resistant core and light blue pre-primed surface reinforced by pre-coated glass mats for superior moisture and mold resistance replacing traditional paper liners.

Ideal for wet areas like shower enclosures, bathrooms, kitchens, and swimming pool halls with frequent humidity exposure, it serves as an excellent tile backing, offering a strong, monolithic structure for direct tiling or smooth decoration, easy handling, and lasting integrity.
