Benchmark series decking – attractive Thermory thermowood decking that ticks all the boxes

Timeless, functional, durable and environmentally friendly. These are all qualities that a decking product should offer – and that’s exactly what our Benchmark Series is all about.

Each decking board is thermally modified, resulting in environmentally friendly products with a natural beauty that lasts for generations.

Depending on the profile, Benchmark decking boards can be installed with screws, clips or PaCS – the world’s simplest screwless system. Most profiles can be ordered with an end-matching solution, meaning that the joints don’t have to rest on joists, dramatically reducing wastage, labor costs and installation time.

Your unequalled hardwood decking choice

Our Benchmark thermo-ash decking is exceptionally durable and dimensionally stable with a deep, rich color. It would be no exaggeration to say that Benchmark thermo-ash is the dream real wood decking material – timeless, stunning, long lasting, barefoot friendly and easy to install.



The new durability standard for softwood decking

Benchmark thermo-pine redefines expectations for softwood decking. With unbeatable durability and stability, our thermally modified Scots pine decking benefits from distinct knots, a beautiful golden-brown color and no visible sapwood.

We can offer our thermo-pine decking with the Nordic Swan Ecolabel. Wood carrying this Ecolabel comes from responsibly managed forests, is chemical free and offers great durability in outdoor conditions.



Just exceptional softwood decking

Our Benchmark thermo-spruce, sourced in Scandinavia, offers a softwood solution with exceptional rot resistance and longevity combined with rustic knots and a naturally light color. When installing, it’s important to ensure that the heartwood (the side of the board closer to the center of the tree) is facing downwards.

We can offer our thermo-spruce decking with the Nordic Swan Ecolabel. Wood that carries this Ecolabel comes from responsibly managed forests, is chemical free and offers great durability in outdoor conditions.

Why thermally modified wood?

Thermally modified wood (thermowood) is the most reliable option if you’re looking for a durable and dimensionally stable material for outdoor conditions. The high temperature of thermal modification changes the structure of the wood, significantly improving its durability and resistance to weather conditions.

The biological resistance of the wood increases as the nutrients in the wood become more difficult to reach for pests and molds.

The wood’s moisture absorption capacity and speed decreases, resulting in reduced moisture deformations. The wood maintains its dimensional stability, meaning that it doesn’t cup, twist or bend as much as other wooden decking products.

Thermal modification leads to less internal stress in the wood, significantly reducing material consumption during construction.

The thermal and sound insulation performance of the wood improves.

Heat treatment also gives the wood a delightful darker tone.

Thermal modification is chemical free.
