GBOARD MR H3

OVERVIEW

Gboard® MR H3 is a moisture resistant board with silicon oil in the core having an average percentage, between 10 and 25 %, of water absorption. The oil acts as a water repellent rendering the core more resistant to moisture. Gboard® MR H3 is the perfect suit for areas of high humidity.

Gboard® MR H3 is composed of the best quality gypsum, non-toxic minerals, and moisture repellent additives which suit health conditions. All materials are certified based on ASTM and EN standards and tested in approved laboratories.
