Thermo treatment is a chemical-free process resulting in unmatched durability and natural resistance to termites and pests. - Lowest Maintenance
The improved dimensional stability allows for extended maintenance intervals compared to other wood products. - Repels Moisture
Thermally-treated wood naturally repels moisture to prevent warping, shrinking, and swelling of the wood. - Class B Fire Rating
Reduced combustibility due to thermo-treatment. - Exotic woods look
The brown color is consistent beyond the surface.

Cut it, sand it, nail it, drill it, paint or stain it as you would practically any standard-grade lumber, using the same standard tools.
Take into consideration that thermo-treated wood is drier (4% EMC), lighter in weight, and a little more brittle than non-treated wood.
Install wood siding over furring strips (use 1 or 2-foot span) for ventilation. Use outdoor-rated nails or screws. Use finishing nails or installation clips for T&G siding for the hidden fastening look. Thermo-treated wood furring strips are available.
Saw speed will affect the cut quality; generally, the higher the saw power, the better the cut quality.
A high-quality sealant with UV protection should be used after the first one to two years.
