External wall use high density fiber cement board
Fiber cement board is a combination of cement ,quartz sand and reinforcing fibers Widely used as a tile backing board,external or interior wall board. Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes. It can be used on the exterior of buildings as a base for exterior plaster (stucco) systems and sometimes as the finish system itself.
Cement board adds impact resistance and strength to the wall surface as compared to water resistant gypsum boards. Cement board is also fabricated in thin sheets with polymer modified cements to allow bending for curved surfaces.
We can provide various size of this board,and we gurantee our board is 100% non asbestos.
