Detailed Product Description

SIGMA Fiber Cement Board contains inorganic raw materials such as cement, silica powder and reinforced cellulose fiber as the main materials. All SIGMA boards are autoclaved to become stable product. SIGMA Fiber Cement Board does not contain any of asbestos fiber, however, it has strong bending strength like those with asbestos. SIGMA 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.
