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.
25+ Years of Rot Resistance
Benchmark Ash has been awarded Class 1 Durability, promising 25+ years of rot resistance – durability that few products, natural or engineered, can truly compete with. This is a result of the thermal modification process.
Stunning Color Evolution
Benchmark Ash is a deep, rich chocolate brown color- the natural result of the thermal modification process. Over time and left untreated, it will slowly turn a stunning grey. To protect the color, simply oil with a UV protectant.
Clean, Sustainable Material
Thermory Benchmark Ash cladding is a truly green product – it’s sourced from healthy, renewable forests in Northern Europe, and the modification process is so clean, the boards are safe for burning as a means of disposal.

Wood’s natural aging process is influenced by how much exposure it has to the elements. The more Benchmark Ash is exposed to UV light and rain, the faster its color will transform from brown to silver—sometimes in as little as six months. To maintain your wood’s natural color outdoors, simply treat the boards with a penetrating UV protective oil.
