Benchmark Ash cladding is created from thermally modified white ash, sourced responsibly from naturally renewing forests in Northern Europe. It combines the simple sophistication that only comes from real wood with rot resistance and stability that only comes from Thermory’s expert thermal modification process.
Thermory interior and exterior cladding* offers unequalled rot resistance and dimensional stability, while bringing the sophistication of real wood to your walls. From the classic elegance of Benchmark Ash and Pine, to the bold look of Ignite, to the rugged outdoorsy style of Kodiak, Thermory cladding is made to make you stand out. Each board is carefully thermally modified using only heat and steam, then meticulously milled to ensure it arrives straight, flat, and ready to install. The modification process doesn't add any chemicals, additives or foreign materials to the wood - it simply enhances the natural properties of the wood fibers to leave each board even more durable, stable and beautiful than before.
