About Radiata pine Thermowood

Radiata pine, thermally modified to 4–7% moisture content. Dark brown, weathering to grey/charcoal.

New Zealand radiata pine, Prime grade.

The thermal modification uses only heat and water, so the cladding is chemical free.

Profile and fitting

Boards fix together by inserting the tongue into the groove. They can be fitted horizontally or vertically; fit horizontal boards tongue uppermost so moisture runs off.

Grades and options

  • Prime grade (all our radiata is Prime).
  • End matching (tongue and groove on the board ends) lets you place joints where they fall rather than on a batten, which speeds up fitting and reduces wastage.

Good to know

  • Natural timber varies: expect some differences in colour and grain from board to board and from the photos.
  • Thermowood can split, so allow an extra 10% on top of your usual wastage. Knots may remain after planing; they don't affect durability.
  • Boards left exposed to changing weather before fitting are likely to cup, warp and split. We suggest fitting between October and April where possible, within 7 to 14 days of delivery.
  • Sizes are nominal and can vary slightly with moisture content.
  • Not sure? Order up to two cladding samples first.
