Siding -
Houses can have a variety of different siding types (brick veneer, stone veneer, stucco, vinyl, wood, aluminum, HardiPlank™, etc.)
HardiPlank™ is the registered trademark name for fiber cement lap siding manufactured by James Hardie International. It is available with a variety of textured finishes to give you the look and feel of wood siding, yet the product is resistant to fire, termites and rot.
HardiPlank™ can be installed with face nails or blind nails. Face nails go into the face of the plank and are visible when the job is done; blind nails are hidden by the layer of planks above. Galvanized 6d nails or 2" siding nails are used for face nailing; 2" siding nails or 11ga roofing nails are used for blind nailing.
HardiPlank™ is installed directly over studs (16 or 24 iinches on center) or directly to 7/16" sheathing. It can also be installed over foam insulation. The manufacturer warns that you must include a water-resistant barrier under the product (roofing felt is a cost-effective moisture barrier) to keep water out.
A 1/4-inch lath along the entire length of the wall at its base is installed first. When the first course of planks is nailed over the lath, the planks will be set at the correct angle.
The siding planks will be cut to length with shears (the preferred method) or with a circular saw using a carbide-tipped blade. You can also use a carbide score and snap knife to score the planks prior to snapping them.
The first course of planks is installed over the water-resistant barrier, flush with the bottom of the lath strip. Planks are attached to studs with a nail. If face nailing is used, nails are driven 3/4" to 1" above bottom of plank. If blind nailing is used, nails are driven 1" below top of plank. Nails should be driven in straight and should be flush with the surface of the plank.
The ends of adjoining planks are butted so there is some modest contact between them. If there is space between planks, caulk will be needed.
The second course of planking (and all subsequent courses) are installed with a minimum 1 1/4" overlap over the course below. The joints must be staggered to help keep moisture out of the walls.
The area extending out from the house under the roof is known as the soffit (parallel to the roof).
The fascia boards are perpendicular to the roof.
The soffit is perforated so that air can flow into the attic and up through the ridge vents to ventilate the attic.
