Fiber Cement Boards (Wood Grain) are high quality building materials. The board contains inorganic raw materials such as cement, silica powder and reinforced cellulose fiber as the main materials. All HUILON boards are autoclaved to become stable product. HOLY fiber cement board does not contain any of asbestos, however, it has strong bending strength like those with asbestos. HUILON fiber cement board can be applied not only for the interior use but also for the outdoor wall system. It has low water absorption rate and high impact resistant ability. These good advantages make it suitable for any purposes of applications.
