Cement fiber sanding board What are its features? How do I install it? Where is it used?

　　Characteristics of cement fiber sanding boards:

　　Fire-resistant: Non-combustible Class A—when exposed to fire, it will not burn and will not produce toxic fumes. It has low electrical conductivity, making it an ideal insulating material.

　　Waterproof: Even in semi-outdoor, high-humidity environments, it maintains stable performance and will not sink or deform.

　　Sound insulation: Low thermal conductivity, excellent thermal insulation performance, high product density, and superior soundproofing effect.

　　Lightweight and high strength: The panels pressed by the 5,000-ton hydraulic press not only have high strength but are also resistant to deformation and warping. They are lightweight and well-suited for applications such as roof ceilings.

　　Simple construction: The dry-process installation method makes the installation of furring and panels straightforward and fast. Deeply processed products further feature ease of installation and superior performance.

　　Economical and aesthetically pleasing: Lightweight and compatible with keel structures, effectively reducing construction and decoration costs; uniform appearance with a smooth surface—direct use ensures even coloration of building surfaces.

　　Safe and harmless: Radiation levels are below the national “Radiation Hygiene Protection Standards for Building Materials,” and measured values are equivalent to those found on a lawn located 20 meters away from surrounding buildings.

　　Long service life: Resistant to acids and alkalis, corrosion-proof, and immune to damage from moisture, insects, and ants. Moreover, its strength and hardness increase over time, ensuring an exceptionally long service life.

　　Good workability and secondary finishing performance: The material can be sawed, drilled, carved, nailed, coated, tiled, or wall-covered according to actual needs.

　　 Cement fiber sanding board During installation, first lay out the lines according to the drawing requirements and the actual on-site dimensions. Use suspension rods to securely fasten the main joists horizontally to the floor. The spacing between main joists should be around 1 meter, and the furring strips should be installed at the same horizontal level. When laying the cement pressure boards, orient the longer side of each board perpendicular to the direction of the secondary joists, and stagger the joints along the width of the boards. At positions 0.5 millimeters from the board edges and 50 millimeters from the board corners, the screw spacing should be approximately 180 to 200 millimeters. Before sealing the boards, use strings stretched across the board surface according to the grid pattern of the joists, and pre-drill shallow holes at the locations where nail heads will pass through, ensuring that the board surface remains smooth and the screw heads are fully embedded in the boards. The gap between adjacent boards should be no less than 5 millimeters. For large areas and long corridors, expansion joints should be left every 10 to 15 meters at the ceiling level.

　　Therefore, cement fiber sanding boards are high-performance fiber-reinforced cement boards that undergo autoclave curing at high temperatures. With a density of 1.60 g/cm³, these boards exhibit excellent performance, outstanding stability, light weight, high strength, and superior weather resistance. They are primarily used for exterior wall decoration and thermal insulation and energy-saving systems in buildings, and are also widely employed in interior decoration. Fiber-cement boards can be used effectively as flooring for steel structures, dry-hung exterior wall panels, curtain wall backing panels, waterproof wall linings for kitchens, outdoor billboards, and as fire-retardant materials in various indoor renovation and fire-resistant projects—including metallurgical facilities, commercial buildings, entertainment venues, shopping malls, hotels, archives, and public spaces.
