Tiger Super Hard


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).

Test method
  • 1. Bend fracture load: According to JIS A 690
    : Load is applied perpendicular to the longitudinal direction of the board.
    : Load is applied parallel to the longitudinal direction of the board.
  • Young's modulus: Calculated from deflection amount at bending fracture load measurement
  • Shock resistance:
    According to JIS A 1408 (Bending and impact resistance test method for construction boards).
    * Entire surface is supported on sand and 530g of spherical weight dropped into it from these heights
  •  9.5mm thickness: 500mm high, 12.5mm thickness: 650mm high

Applications

  • For parts requiring strength such as partitions and hallways between rooms in hospitals, interior walls of school classrooms and gymnasiums, as well as spandrel walls in stairs.
