Calcium Silicate Board 1. Introduction Calcium silicate board is a most widely used material in China due to its good performance and easy-processing feature. It is moisture proof and heat resistant, so it is commonly used for wall and ceiling to keep away humidity and to slow down the spread of fire. What is more, it can be cut, nailed and screwed, making installation much easier. Then labor cost could be reduced as well. 2. Application Calcium silicate board is moisture proof and heat resistant, strong and durable, thus commonly used as wall and ceiling for house, office, warehouse, shopping mall, residential complex etc. 3. Specifications Size (mm) 2440*1220, 2400*1200, 3000*1200, Thickness (mm) 4.5 – 20 Moisture content (%) ≤10 Density (g/cm3) 1.15-1.5 Wet Expansion Rate(%) 0.25 Thermal Conductivity (W/m•K） ≤0.30 Bending Strength(MPa) 9-12 Non- combustibility GB 8624-2006 Class A 4. Advantages (1). Durable (2). Insect-free (3). Moisture proof (4). Heat-insulated (5). Easy installation (6). Safe and Harmless 5. Installation Processes for Interior Wall (1). Draw lines according to construction plan and install door frames. (2). Install top keels and floor keels according to the lines. Fix the keels on base walls with nails, and the distance between nails is 600mm. (3). After installation of top and floor keels, mark down the installation points of vertical keels, with 450mm distance between each other. Then check positions of door and other holes and avoid installing boards on their frames. (4). Install vertical keels according to installation points. Two ends of vertical keels should be separately installed into top keels and floor keels. Fix them after adjusting and leveling. Keels near walls or poles should be fastened by screws or nails, and the screw/nail distance is 1000mm. (5). When walls are higher than 3m, it is required to install through keels, which should be fastened by nails or screws. (6). Check the installation of keels and door frames and make sure they are suitable for board installation. Install the boards starting from door frame or from one end of the walls if there is no door frame. Calcium silicate boards should be fastened by self-tapping screws. Distance between screws is 200mm (near walls) and 300mm (away from walls). Distance between screw and board is no less than 10mm and no more than 16mm. When fixing screws, boards must be close to keels. Then install electric pipes, water pipes, electric cabinet and other fire-proof, sound-proof, water-proof materials. Repeat the same procedures and install the boards from the other side. But seams must be staggered from the first side. For a dual-layer wall installation, seams of the second layer should be staggered from those of the first layer as well. (7). There are 3 methods to deal with calcium silicate board joints, which are bed joint, deep seam and taped seam. The processes are as follows. Puttying: Cleaning away dust between gaps and put putty into it, making it smooth on surface. Pasting binding tapes: Put binding materials on it when the putty is finished. First scrape off a thin layer of putty, about 1mm thick and same width as the tapes. Then put the bonding tapes on it and fasten it by driving out the air inside. Scraping the middle-layer putty: As soon as pasting the binding tapes, scrape a middle-layer putty about 80mm wider than binding tapes, thickness about 1mm, making the tapes sunk into the putty. Flattening: Use a big scraper to fill the wedge groove and board with putty and smooth the surface.

Fiber Cement Board 1. Introduction Fiber cement board is another most widely used building material in China. It could be used as wall and floor panel both inside and outside buildings due to its better performance than calcium silicate board. With main ingredients of Portland cement, quartz powder, slaked lime and fiber, being processed with high pressure and high temperature, fiber cement board turns into a very strong panel with same structure of marble. Moreover, by the improvement of technologies, we are able to produce it without any asbestos, which is really good for human health. 2. Application Fiber cement board is good against water and heat, lighter than concrete but with high bending strength, thus good to be used for outdoor wall cladding, flooring, billboard, wall separation etc. It’s an ideal replacement of concrete. 3. Specifications Size (mm) 2440*1220, 2400*1200, 3000*1200, Thickness (mm) 4.5 – 30 Water absorption (%) ≤40 Density (g/cm3) 0.95-1.45 Wet Expansion Rate(%) 0.25 Thermal Conductivity (W/m•K） ≤0.3 Bending Strength(MPa) 5.5-16 Non- combustibility GB 8624-2006 Class A 4. Advantages (1). Durable (2). Fireproof (3). Insect-free (4). Waterproof (5). Easy installation (6). Environment-friendly 5. Installation Processes for Exterior Wall Cladding (1). Clean up walls and boards. (2). Draw lines on walls according to construction plan. (3). Reserve holes for doors, windows or other equipments. (4). Drill holes on walls according to the lines mentioned above, and then use stainless steel anchor bolt to fasten zinc-plated angle steels on them. (5). Use stainless steel screws to fix L-shape keels and angle steel. (6). At external corners and internal corners, use long L-shape angle steels to fasten two keels by rivets, making the whole keel system strongly combined together. (7). Use bolts to fasten hangers that connected to L-shape angle steels. (8). Fix 4 corners of fiber cement board on 4 hangers. Make sure the lower corners connected to lower hangers are sitting right on lower L-shape keels, and upper ones on upper keels (9). Fill connecting joint of boards with 3 mm thick sealing glue when they are fastened. (10). Repeat the process for other panels and don’t forget the waterproof treatment. (11). Double check the whole project and do the cleaning.

Installation Processes for False Ceiling (1). Draw lines on ceiling according to construction plan, and install hanging bars. (2). Install main keels by following sequences. (a) Use size UC50 or U38 steels as main keels and the distance between two keels is 1200mm. (b) Hangers must be installed on main keels and fasten by screws. If the main keel is not long enough, there must be a overlap on the joint point with a hanger clip. (c) Remember to check the leveling all the time. (d).It is required to use T-shape reinforced sub keel when installation is near lamp and ventilation outlet. (e) After installation of edge keel, check leveling of the whole system again. Adjust the edge keels first, and then the sub keels in accordance with them. If it is necessary you can adjust the main keel. (f). Choose appropriate size and thickness of ceiling board as per design. Normally we use 603*603*6mm. White gloves are recommended when installing the boards to avoid spots and dust.
