fiber
cement siding is not unlike that of other clapboard materials: the sheets or
boards are cut to fit and then nailed in place. Cutting fiber cement siding
usually requires mechanized metal shears—the boards are too tough to cut using

durable once installed, fiber cement siding is fairly delicate before; it is
prone to chipping and breakage if improperly handled. Additionally, some caution
must be exercised to properly ventilate areas where james hardie fiber cement

installation process can cause silicosis. Before or after installation, fiber
cement siding can be painted (for areas of exposure, weatherproof paint must be
used).
