Calcium silicate board can be easily cut on site by using a sharp fine-toothed panel saw or hacksaw. Place tiles face down on a clean, smooth surface for cutting. When power sawing and sanding, nuisance dust levels may need to be controlled. In order not to damage the finishes of Fiber cement tiles, it is recommended that the installer should wear gloves to lay the tiles. For better acoustic and thermal insulation performance, a layer of mineral wool or fiber glass can be laid on top of the Fiber cement tiles or panels.
