Thermal Ash

Thermal Ash is a long lasting and beautiful natural wood product perfect for decking and cladding. 

THERMAL ASH

Thermally modified Ash is a near perfect wood for exterior projects. It holds up well in wet environments, mills easily, and cuts clean, making it perfect for decking and cladding. 

Thermally Modified for Maximum Sustainability

Thermal modification begins by heating the wood to 450º Fahrenheit in a vacuum with all oxygen removed from the space. While Ash will combust at 300º Fahrenheit,  the removal of the oxygen prevents combustion and allows the sugars in the wood to caramelize. The caramelizing of the sugars gives the Ash the dark brown colors and essentially begins a petrification process which makes the wood water resistant. The life expectancy of cladding and decking made from Thermal Ash is about twenty five years. 

A Beautiful Dark Brown

The color tone of Thermal Ash is a fantastic range of deep browns and brownish red hues, think about the crust of Crème Brûlée. The caramelized sugars create these colors throughout the wood, making it an absolutely gorgeous wood.
