There are three kinds of core material for raised floor panel, one is wood core (High density chipboard), another one is all steel structure with cementitious infilled, the newest one is high strength inorganic material core board (Calcium sulphate floor panel), Compare with these three kinds of material. Why calcium sulphate access floor is more and more popular in the market? What’s the advantages of calcium sulphate raised floor?
Perfect fire-proof performance
Compare with three core board of raised floor panel, fire resistant of chipboard wood core is just B1, and calcium sulphate floor board is A1 tested by BS13501 the highest level of fire resistance. Although all steel floor panel can match same fire resistance level, but metal material has more thermal deformation than calcium sulphate floor board which is inorganic material. That means calcium sulphate has better dimensional stability than all steel floor panel against high temperature.
Thermal insulation
Calcium sulphate raised floor is made by inorganic silicate material which has quite good thermal barrier effect which is total combustible solid material, When the flame of 600 degree applied to one side of the floor, it will take one hour to transfer the heat to another side. It will have more time to escape or rescue the property while get a fire. All steel floor panel is made by steel sheet with cementitious infilled, the metal has good thermal conductivity, which is easy to transfer the heat.
Recyclable and environment protection
It’s a trend to use recyclable and environment protectional building material for future construction. The wood core raised floor is economic product as the first generation of raised floor. But it’s fire-resistance and environmental protection is criticized. All steel access floor has good fire-resistance, but the structure of steel sheet encased with cementitious infilled is complicated for disassembling and recycling. It’s quite hard to meet the LEED requirement. Calcium sulphate raised floor panel is composed with gypsum powder, water and reinforced fiber which are total inorganic and same with main construction materials. It’s totally recyclable and eco-friendly.
Sound insulation and impact resistance
As a raised floor system, the floor panels are supported by pedestal and stranger system, the under structure of the floor level is hollow space, so the concern from the user are not only the structure of strength and safety, but also the sound insulation and impact resistance, Calcium sulphate raised floor has perfect sound insulation and impact performance, the horizontal transmission airborne noise is under 35dB and vertical transmission impact noise if less 30dB ,and impact loading is more than 780kN, So it has excellent walking foot sense on the calcium sulphate floor .
Swelling and stability
Dimensional stability is very important for the floor system it will affect the life time, especially under the condition of high humidity and changeable temperature, Calcium sulphate floor is made by inorganic core material with high density which is total water-proof, it’s just 5% water swelling compare with wood core, meanwhile it has less thermal deformation than all steel raised floor.
Calcium sulphate raised floor is new generation of raised flooring system, it is water-proof, fire-proof, recyclable, thermal insulation and sound insulation, which brings you perfect experience of long life time and safety.
