Bevel-back weatherboards

Bevel-back weatherboards were among the most common wall claddings during the 1940s-60s.

Bevel-back weatherboards were commonly used in both private and state housing.

As well as being used as a principal wall cladding, they were sometimes used in the gables with other cladding materials, in particular brick.


Native timbers used for weatherboards were commonly rimu as the supply of matai, totara and miro had become scarce. The 1960s saw the use of dressing grade treated pinus radiata clears as well as imported redwood and western red cedar clears and the introduction of finger jointed weatherboards and exterior trim timbers.

Standard board size was nominally 6 x 1” (150 x 25 mm) but once seasoned and dressed, the boards had a typical finished size of 5½” x 25/32” (140 x 19.8 mm) to provide a 4¼” (108 mm) cover with a 1¼” (32 mm) overlap.

Weathergrooves were not common in the weatherboards. Weatherboard running joints were scarfed (the boards were cut at 45° along their edge).

External corners were typically finished with boxed corners with scribers (Figure 2) or joints were mitred (and covered with soakers to protect the corner and keep the joint covered if it opened due to timber shrinkage (Figure 3).

Timber board sizes for  boxed corners were nominally 4 x 1” (100 x 25 mm) and 3 x 1” (75 x 25 mm) to give a symmetrical corner detail. They were fixed over the weatherboards at the external corners in both directions. Scribers were fitted at the edges of each facing board to cover the gaps left by the slant of the weatherboards.

Internal corners had angled flashing installed behind the weatherboards. The boards on one wall were then scribed and fitted to the boards on the adjacent wall (Figure 4).

Window and door openings

Windows and door openings were trimmed with facing boards of the same size and finished in the same way as the external corner facing boards.
