Tempo:
the siding to determine the maximum board exposure. The number of boards needed to clad a wall must respect the maximum allowed exposure. This may lead to an installation in which the exposure is less than the maximum permitted. Attempt to have the bottom of a board placed over the top of a window aligned with the top of the window cap (Figure 111).
Tongue-and-groove matched siding (see Figure 109) is 184 mm (8 in. nominal) or less in width. The first board is face-nailed near the grooved edge and angle-nailed through the tongue. Each successive board is fitted tightly to the preceding board and angle-nailed through the tongue. A nail set is used to finish off the nailing.
Bevel siding must have a butt thickness of at least 12 mm (1⁄2 in.) for widths of 184 mm (8 in.) or less and 14.3 mm (9⁄16 in.) for widths greater than 184 mm (8 in.). The top edge should not be less than 5 mm (3⁄16 in.) thick.
Drop (or matched) siding (see Figure 109) should be at least 14.3 mm (9⁄16 in.) thick and 184 mm (8 in. nominal) or less in width. It is produced in a variety of patterns with matched or shiplap edges. Stagger the butt joints between
