Developed in Finland, and successfully used commercially in Europe since the 1990’s, Thermal Modification is a chemical-free method of heat treating wood with nothing more than steam and high temperatures in order to increase the woods water repellency, insect and rot resistance and dimensional stability.
The Thermal Modification process improves wood on a molecular level, which allows sustainable species that typically do not perform well in outdoor or wet environments to be used in a wide variety of interior or exterior applications. For this reason Pakari may just be the “greenest” lumber resource on the market.
The process begins with the harvesting of FSC-certified plantation grown Radiata Pine. After the pine is harvested and the lumber is thoroughly graded for any defects, it is moved to a specially designed kiln where it begins the three phase process of Thermal Modification.
Inside the kiln, temperatures steadily increase to approximately 500°F, dropping the wood's moisture content to nearly zero. At these high temperatures, chemical and structural changes occur in the wood that make it more dimensionally stable, as well as insect and rot resistant.
Once modified, steam is introduced into the kiln to recondition the wood, returning its moisture content to between 6-7%. The entire process takes approximately 65 hours.
Next, the Thermally Modified wood is transported from the kilns to a solar powered milling facility in Chico, CA, where it is manufactured into a number of products for exterior or interior use.
Pakari is in good supply and a cost-effective choice. Ask us about our custom siding and interior paneling options.
