Amazing! The best building material for the industry.
Cement foam board is widely used. Its superior performance can be seen in:
Achieving good fire insulation performance
The board is classified as a non-combustible, inorganic thermal insulating material of class A. It can maintain its integrity even at high temperatures and improve the fire performance. Closed porosity is more than 95%. It has excellent thermal insulation properties.
Sound insulation with excellent performance
Cement foam board can have a sound insulation coefficient of more than 45 decibels due to its porous bubbles.
Lightweight seismic capacity
Cement foam board can resist a magnitude 9 earthquake by welding steel structure. Its density is about 250kg/cubic-meter.
Construction is efficient and convenient
Cement Foam Boards can be easily constructed, they require little time to construct and do not need extra materials like sand or cement. They are also easy to stack and use less space. Cement Foam Board can be constructed in 60 minutes by three people, compared to the traditional block walls.
Strengthens the bonding and compression forces
Adding special fibre enhances the compression strength of the foam cement board. The national testing agency verifies its bending load to be greater than three times weight (1.5x the national standards), compressive force of more than 5MPa, (3.5MPa for the national standards), and hanging force of more than 1,500N.
Environment protection, energy savings and non-toxic and safe
Cement fly ash is used to make cement foam. It won't melt at high temperatures, and it doesn't emit any toxic gases. It's a material that is both environmentally friendly and safe. Cement foam board is not recyclable, and this fact has been recognized by the national industrialization policy.
Cement Foam Board is used widely in industrial plants with large spans, warehouses, machine garages of all sizes, stadiums exhibition halls airports large-scale utilities and mobile homes. It's also used as wall insulation for residential walls, and mezzanines. The problems associated with foam insulation before have been overcome by cement foam board. These include poor thermal insulation properties, high thermal conduction, and cracking.
