Super Hard Gypsum Board
Yoshino Board
Super hard gypsum board offering even greater strength, recommended for partitions and walls in hospitals, school classroom, gymnasium, etc.
Super hard gypsum board offering greater strength than ever before. Recommended for parts requiring strength such as partitions and hallways between rooms in hospitals, school classroom walls, gymnasium walls and spandrel walls in stairs.
Features
-
Bending fracture load is twice as much as that of standard gypsum boards.
-
Surface hardness is four times as much as that of standard gypsum boards.
-
Water absorption rate is only 1/3 of that of standard gypsum boards. This means that Tiger Super Hard has the same level of water resistance as our sheathing gypsum boards (water resistant type).
