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
- Purpose made "fibro cutter" (an Australian term)
- 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 areas throughout Australia .
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 standard EN 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
