How To Install Bevel Back Weatherboards

B evel-back timber weatherboards have been used on New Zealand buildings for more than than 150 years. The first boards were simply foursquare inch-thick planks that were installed horizontally, with the upper lath overlapping the lower.

Return of bevel-back weatherboards

Every bit is common with many claddings, there have been periods when the bevel-back timber weatherboard was popular, similar the 1920s (run across Figure 1) and 1940–50s, before fading from popularity.

Since the leaky edifice crisis, there has been a marked resurgence in the popularity of bevel-back timber weatherboards, particularly when installed over a drained and vented crenel.
