Fiber cement siding is a building material used to cover the exterior of a building in both commercial and domestic applications.Fibre cement composites are composed of Portland cement, silica, water and wood pulp and are manufactured using the so-called “ Hatschek process”. This process was initially developed for the production of asbestos composites, but is now used for something that can actually be used as a viable asbestos replacement material: fibre reinforced cement composites, or fibre cement for short.
As part of the Hatscheck process, cellulose fibers are pulped in warm water then mixed with cement, silica, and other additives. The fibre cement mixture is transferred onto a conveyor belt, then a laminating roll. This process is repeated and multiple layers of fibre cement are laminated to the required thickness.
