Thermally Modified Decking with
Rot Resistance to the Core

Thermory's expert thermal modification process results in deck boards that are rot resistant to the core, offering up 25+ years of rot resistance. Meticulous milling leaves each board ready for use, and innovative solutions such as PaCS and JEM Joints make installation a breeze. Each board is harvested from naturally-renewing forests, and modified using only heat, steam, and certified wood scientists, creating a sustainable real wood deck that is both stunningly beautiful and unequalled in durability.

JEM Joints Make Installation a Breeze

Many Benchmark Ash decking profiles include JEM (Joint End Matched) Joints that free you from joist requirements. JEM Joints interlock with each other, eliminating the need for joints to rest on joists and drastically decreasing waste.

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.

25+ Years of Rot Resistance

Benchmark Ash has been awarded Class 1 Durability, meaning it offers 25+ years of rot resistance. This is due to the incredible durability and stability created through the thermal modification process.

Benchmark Ash color transformation.

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.
