The raw materials of fiber cement board are cellulose fiber, silicate cement, quartz sand, water and some additives. It's a kind of high-tech product which formed through accurate dosing by computer program, hatcheck craft and compressed by 14000tons hydraulic machine and autoclave under high temperature and pressure.
1. Interior and exterior wall; Furred ceiling
2. Insulation materials, floor; Road barrierIt's 100% free of asbestos, formaldehyde, benzene and other harmful substances and with excellent performance like high strength, large size, light weight, fire and water proofing, green and environmental friendly, high efficient and energy-saving. Therefore, this kind of new material is vigorously developed and recommended by the country.
1. Thickness: 3.5-30mm
2. Standard size: 1220*2440mm or 1200*2400mm
3. Note: other specification is available

Installation
Tools:
No special tools are required. The products can be used with normal
nails, fastened by normal or self-drilling screws and cut by an
electric power saw with a diamond blade.
Fixing:
Sinoma Board can be fixed to both timber (minimum size 1.5 x 3
inches) or steel frames (at least 0.55 mm thickness). The board
must be supported at the edge at intermediate positions with
centers not exceeding 600 mm. Screws must be located more than 12
mm from edges and 50 mm from board corners.
Fastener:
Fasteners can be both nails and screws. It can be nailed directly
to timber supports with round wire nails. For metal screws, the
size and length of the screw depends on the thickness of the board
and the gauge of framing.
Jointing:
Since fiber-cement board is subject to slight dimensional changes,
a butt joint can be used in dry partitioning areas or where an
exposed joint appearance is acceptable. For better water
protection, either flexible acrylic or polyurethane based sealant
can be used to seal gaps of 3-5mm.
Transportation, Handing and Storage:
Deliver SINOMA Board to the project site in the original, unopened
package and store them in fully enclosed space where they will be
protected against damage from humidity, direct sunlight, surface
contamination and other causes of damage. Handle SINOMA Board
carefully to avoid chipping the edges or damaging units in any way.
Handling and storage practices should follow the manufacturer’s
recommended suggestions at all times.
