The Advantages of Calcium Sulphate Raised Floor

Since 1990s, calcium sulphate raised floor has been widely used in European countries. These years, China ’s awareness of environmental protection, energy conservation and recycling has increased. The market share of calcium sulphate raised floor has increased dramatically at the same time because of the advantages of the floor.

Production process of calcium sulphate floor

The raw materials of calcium sulphate floor are mainly natural gypsum powder(CaSO4 1/2 H2O) and reinforced fiber (primary and secondary fibers), they occupy more than 85% of a calcium sulphate board. Together with other materials such as mineral binder, water, they are mixed and pressed through high voltage. Then the installer should maintain the calcium sulphate board in thermostatic room for around half a month. And should keep it until the bending strength of board can reach 12-15 Mpa.

The advantages of calcium sulphate floor

Environment friendly & recyclable

The content of gypsum powder and reinforced fiber can be more than 85%, the recyclable material of a calcium sulphate board can contains from 90% to 97%. It can meet the requirement of “LEED” evaluation for projects. At the end of its life, recoverable indicator is a very important factor in both economical and environmental aspect nowadays.

Acoustical characteristics

Calcium sulphate floor generates micro-holes due to crystallization. The material structure, design features and high production precision of this floor provide excellent acoustic values. The extremely good walk-on properties offer a high degree of comfort and create a perfect working ambiance.
28-51 dB(with covering)
14-70 dB(without covering)

Fire resistance

Calcium sulphate raised floor owns the best fire resistance in all kinds of raised floor. So it can offer a most valuable solution functional as well as safety advantages. Calcium sulphate floor is non-combustible. And this allows a raised floor to meet a F60 classification, depending on the overall height. The height of the building determines the amount of air (and therefore oxygen) under the raised floor. And it is one of the three basic factors that cause fires.

Moisture resistance

Calcium sulphate raised floor has a good performance to a (slight) degree of moisture. It is easier to maintain and clean floor. Service life of floor will also be longer than a chipboard floor.
