Cement board is resistant to fire, heat and heat resistant cement board suppliers.
A tile backing board is a mixture of cement and reinforcing fibers formed into sheets of varying thickness.Cement board can be fastened to wood or steel studs and attached to plywood for tile floors, kitchen counters and backsplashes.It can be used as a base for exterior plaster systems on the exterior of buildings.
Compared to water resistant gypsum boards, cement board adds impact resistance and strength to the wall surface.The thin sheets of cement board can be bent for curved surfaces.
In cement fibre boards, a plant extract is used as reinforcement, whereas in cement bonded particle boards it is wood.Cement is a binder in both cases.Blue particle boards and cement fibre boards have the same fire resistance properties.Cement-bonded particle boards have higher capacity than cement fibre boards.Cement particle boards can be made from 14 to 1 916 inches (6 to 40mm) thickness and are suitable for high load bearing applications.
The boards are made of a mixture and form a single layer.Cement fibre boards can be made from 18 to 1316 inch (3 to 20mm) thickness.It is extremely difficult to make high thickness boards because they are made in very thin layers.In order to achieve certain board qualities, many manufacturers use Additives like mica, aluminium stearate and cenospheres.The majority of the cement fiber board is made of cement.The use of other Additives like aluminium stearate and PVA is usually less than 1%.In low density boards, cenospheres are used between 10-15%.The actual recipe is dependent on available raw materials and other local factors.
As a tile backing board, cement board has better long-term performance than paper-faced gypsum core products because it will not rot or break down in the presence of leaks.Cement board has a stronger bond with tiles than gypsum board.The cement board is not waterproof.It has good drying properties.A waterproof material is usually recommended behind the boards or as a trowel-applied product to the face of the finish system in areas exposed to water spray.
The weight per square foot is a major disadvantage of cement board.It is more difficult to handle than gypsum board.Tools and saw blades must be used for the cutting of cement board.Pre-drilling of fastenings is recommended due to its hard nature.Cement board is more expensive than water resistant gypsum board, but may provide better long term value.
