Thermowood 'D' Type AT9 Cladding (Per Metre)

Thermowood ‘D’ is produced by treating softwood in special chamber kilns at high temperatures, no chemicals added. The cellular structure changes during the heat treatment and the resulting Thermowood gains a high resistance to moisture or decay causing fungi and becomes more stable in changing climatic conditions which makes it ideal for external cladding.

Our unprocessed Thermowood ‘D’ arrives in lengths usually between 4.2m – 5.1m, if you have specific length requirements then you may make a request above, however, we must emphasize the fact that we cannot guarantee specific lengths.

Face Cover:
18 x 94mm is 70mm
18 x 119mm is 95mm
18 x 144mm is 120mm

All of our Cladding is supplied with a smooth machined finish ready to apply the finishing product of your choice.

Since timber is a natural product, each section may contain a different grain pattern, colour, natural figuring, and some small pin knots.
Additionally, it's important to consider the potential for imperfections such as split or splintered ends. To accommodate these imperfections and ensure you have the necessary length for your project, we advise that you allow for approximately 300mm of extra length beyond the actual usable length. This extra length provides a buffer to trim off any ends that may not meet your quality standards, ensuring that you can work with the highest quality sections of timber for your specific needs.
By accounting for this additional length, you can better manage the inherent variability in timber and achieve a more precise and aesthetically pleasing result in your woodworking projects.
