DYBM™ Fiber Cement Board
DYBM™ Fiber Cement Board Description
DYBM™Fiber Cement Board are high quality building materials. The board contains inorganic raw materials
such as cement, silica powder and reinforced cellulose fiber as the main materials.
DYBM™Fiber Cement Board are autoclaved to become stable product.
DYBM™Fiber Cement Board does not contain any of asbestos, however, it has strong bending strength
like those with asbestos.
DYBM™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.
