 Thermo-Treated Siding  

Two faces smart profile, oiled on four sides

Thermo-treated Siding

Thermally modified Poplar siding looks like rich walnut and is a great alternative to expensive exotic wood solutions.  Poplar has a closed-grain structure and shows a uniform color grain with some natural variations.  As non-treated Poplar has a mix of white, green, and gray colors (sometimes in one board), the thermo modification turns all colors into brown shades, which creates a unique and expensive look of the product.

Thermally modified Pine siding creates a rich wood grain look for any construction and offers the beauty of thermally modified Southern Yellow Pine. We use just the Highest Grade of lumber for thermo-modification, so no knots or holes in our product. 

We developed a two-sides profile for siding shows V-groove on one side and square edge ship-lap on the other side.  These two designs are pretty much covering both preferences of the customers from North and South. 

All Siding products come pre-oiled on 4-sides, which doesn't require any oiling on-site after installation. Oiling protects the initial rich color of the wood for at least one year or more (depends on the intensity of the sunlight).  Like any organic material, thermally modified wood will be fading under sunlight and gradually turns to a grayish color, which doesn't change the product's characteristics.

4-sides factory oiling - Thompson Clear oil-bases sealant.

Siding has sawmill-cut ends considering that the majority of boards will be cut at installation.

In the bundles, siding shipped locked T&G.

Maintenance

Thermo-treated wood, as any organic material, is fading under sunlight. Factory oiling prevents fading for the first 1-2 years (depends on the intensity of sunlight), and to maintain original color requires oiling every 1-2 years. Oiling also prevents seasonal surface checking. If wood faded, it's easy to restore the original color just by lightly sanding the product's surface. 

Warranty

The thermal modification protects the wood against decay for at least 25 years.  Nevertheless, the original appearance of the product depends on timely maintenance and usage as directed.
