Wood grain fiber cement boards
Product Description
wooden grain siding panel adopts the high quality quartz sand,
silicate,natural fiber, and a variety of selected mineral.with high
temperature and high pressure.
The product do not have any radioactivity and harmful elements.
Belongs to new, green and environmental material.
The surface with the typical natural cedar wood grain,appearance
is natural and beautiful. also can prevent the attack of white ant
and sawteeth animals.
The wooden grain siding panel has the feature of durability,
flexibility and creativity, more stable and durable than wood products.
Because of the lower cost and excellent properties,it is accepted
by the foreign and domestic customers,also the best choice of
all kinds of construction.
When choose the coating material, we recommend environmental
water-based paint. For example:water-based pureacrylic coating
Recommend application:
Exterior wall of Villa, apartment,office building, work shop,school
and so on Old building renovation, interior decoration

Installation
Fiber cement cladding is a very heavy product and requires two people
to carry the uncut sheets. Thin fiber cement cladding is fragile before
installation and must be handled carefully; it is prone to chipping and
breakage if improperly handled.
Once the product is cut it may again require two people to install – one
to hold the sheet flush against studwork and the other to nail the product
in place.Cutting fiber cement cladding sheeting usually requires a
mechanised saw or metal hand shears and sheets can be cut to size
in three ways:
Thinner sheets can be scored with a heavy duty cutting blade and snapped
Thicker and denser sheets require cutting by a mechanical saw using a
diamond blade (Masonry blade)
1/8 spacing required between end-joints (cladding seams) later to be
filled with caulking made for fiber cement siding
Metal 6"x6" step flashing required behind overlapping seams to prevent
sheathing damage from water hot dipped Galvanized roofing nails to
hang fiber cement siding
Some caution must be exercised to properly ventilate areas where
fiber cement siding (FCS) is being cut; long-term exposure to the silica
dust generated during the installation process can cause silicosis.
Fiber cement cladding can be painted before or after installation.
(For areas of exposure, weatherproof paint must be used.)
Once the product is fixed the joints are usually covered with timber battens
and the entire wall surface is painted.
Durability
The external cladding products require very little maintenance
once installed and painted. The thicker/denser fiber cement products
have excellent impact resistance but the thinner less dense products
need to be protected from impact. Compared to wooden siding,
fiber cement is not susceptible to termites or rot.[2]
Fiber cement siding using base board materials that have been
classified, by accredited laboratories, as Category A according to
BS EN 12467: 2004 Fiber-cement flat sheets - Product specification
and test methods are sidings which are intended for applications
where they may be subject to heat, high moisture and severe frost.
Fire resistance
Fiber cement cladding is a non combustible material which is widely
used in high bush fire prone area While the best possible Reaction to
Fire Classifications are A1 (construction applications) and A1Fl
(flooring applications) respectively, both of which mean "non-combustible"
according to European standardEN 13501-1: 2007, as classified
by a notified laboratory in Europe, some fiber cement boards
only come with Fire Classification of A2(limited combustibility)
or even lower classifications, if they are tested at all.
Safety
As mentioned previously, long-term exposure to silica dust generated
by cutting fiber cement siding during installation can lead to silicosis
and other lung diseases among workers.[3] Researchers at the National
Institute for Occupational Safety and Health (NIOSH) confirmed these findings,
showing that many of the silica dust particles are in the respirable fraction,
able to penetrate the deepest parts of the lung.[4] Laboratory tests performed
by cutting fiber cement siding within an isolated chamber showed that by
connecting a regular shop vacuum to a circular saw, exposures to silica
dust produced by the cutting can be reduced by 80-90%.
Alternatives
Competitors to fiber cement cladding include products made from vinyl,
polyvinyl chloride, wood composite products (such as hardboardand Masonite)
and aluminum siding
