Thermowood Decking

Thermowood decking is a cost effective and durable product. The timber is a Scandinavian Pine which has been heat treated through a steaming process, this process helps to remove almost all of the moisture from the timber in order to make it as stable as possible. All of the resin is also dried up which helps to prevent rotting and leaking onto the surface of the wood, leaving you with a nice clean finish.

Supplied in a Sawfalling grade, you can expect to see a fairly heavy knot content in the boards, the majority of which are sound, live knots. There can be some dead knots though, so we do recommend ordering 10% extra so you can cut these out of the board.

Unpainted Thermowood machines well so you get a smooth finish for your outdoor decking, there are a range of profiles on offer including:

  • IWD1
  • IWD2
  • IWD3
  • IWD4
  • IWD5
  • IWD6
  • IWD7

There are three different profiles with two size options for each profile, select your profile in the list above and input your m2 requirements into the calculator for an instant price.

Although you don’t need to treat the timber because of how stable it is, it does take a paint or oil well if you would like to change or preserve the colour. If you leave it, the Thermowood will naturally turn silver grey over time like all timber.

An alternative to Siberian Larch

One of the reasons we are so keen to offer this timber along with our premium range of hardwoods and durable softwoods, is so that we have a suitable alternative for Siberian Larch which is currently unavailable. With Canadian Cedar prices rising to levels we haven’t seen before it has become more important than ever to offer a cost effective and quality option.

Our Thermowood is available as PEFC certified because it is sourced from sustainable sources.
