Calcium sulphate

Raised access floor system made of calcium sulphate (gypsum)

Calciumsulphate, a natural material, also known as gypsum, is mined in open cast mines. Raised floor panels made of calciumsulphate have extremely high densities and are extremely rigid.

Gypsum has very good properties in terms of load bearing and fire resistance as well as acoustic. Due to the used materials which are gypsum, water and paper fibers the emission in rooms is zero.

Calciumsulphate panels are offering a high-flexibility and are the most versatile product family in our portfolio.

Raised Floor, hollow floor, acoustic Floor, Load capacity from 1 to 20 kN.

Calciumsulphate raised floor made of gypsum is applicable with almost every type of covering.
