Hardboard Siding Hardboard horizontal siding (Figure 110) is made in a wide range of colours. It often has splines for interlocking the panels and is installed in a manner similar to metal and vinyl siding. Some manufacturers require that their hardboard siding be installed over furring.
Lumber Siding Lumber siding should be sound and free of knotholes, loose knots, checks or splits. Cedar and pine are the most commonly used species. It has also become more common to use pressure-treated lumber for siding or wood that has been factory-finished with stain or paint. The finish should cover the front and back surfaces of the siding to reduce water absorption. At the time of application, the siding should have moisture content similar to what it will be exposed to, that is, between 12 and 18 per cent, depending on a region’s humidity and climate. Rainscreen wall assemblies (Figure 110, for example) are required in wet, humid climates such as the coastal regions of Canada.
A vertical space is created behind the siding to facilitate drainage and drying. This is accomplished by mounting the siding on furring strips nailed on top of the sheathing membrane to the studs behind. Corrosion-resistant nails such as hot-dipped galvanized nails will hold the siding permanently and will not disfigure the paint surface. Casing or siding nails are normally used for this purpose. Drive the heads flush with the face of the siding. If finishing nails are used, set the heads below the surface and fill the holes with putty. The length of the nails required depends on the thickness of the siding and the type of sheathing used and must be long enough to penetrate at least 25 mm (1 in.) into the nailing support.
Horizontal Application Bevel or feather-edge siding (see Figure 109) is installed from the bottom up with the bottom edge of the lowest course mounted on a 6 mm (1⁄4 in.) thick furring strip. Overlap each succeeding course at least 25 mm (1 in.) over the lower course. Spacing for the siding should be planned before the installation starts. Deduct the minimum lap from the overall width of
