fibre cement board

Fiber cement is a composite material made of sand, cement and cellulose fibers. Thermal resistance and sound transmission vary greatly between fiber cement products. Fibre cement thicknesses vary between 4.5-18mm and also vary in density – the lower density resulting in a fibrous rough edge when cut and the higher density having a cleaner smoother edge when cut. Generally the thicker and denser the product the better resistance it will have to temperature and sound transmission
