The new durability standard for softwood decking

Benchmark thermo-pine sets a new standard for softwood decking. Thermal modification makes the pine more durable and stable while emphasizing its warm golden-brown color and characteristic knot pattern – all without any chemicals.

We offer a wide range of profiles, including profiles that allow for hidden fixing, enabling a flawless finish and easy deck installation.

Thermally modified wood is a natural, durable and environmentally friendly choice.

Why choose Benchmark Thermo-Pine decking?

Thermory Benchmark thermo-pine decking is perfect for you if you enjoy the characteristic charm of pine but you need a more durable result.

Thermal modification increases the durability of pine (class 2, 15+ years), which is extremely important for outdoor use.

The lower moisture absorption capability and rate of thermally modified wood results in less moisture-induced deformation, making it a great choice for outdoor use.

Thermal modification gives pine a beautiful golden-brown tone.

In addition to being durable, our thermally modified pine is environmentally friendly, as the thermal modification process is chemical free and no harmful waste is generated.

We offer thermo-pine decking with the Nordic Swan Ecolabel, which certifies that the wood originates from responsibly managed forests, is free of chemicals and is extremely durable when used outdoors.

Pine offers exceptional mechanical properties

Scots pine (Pinus sylvestris) is a coniferous tree of the pine family, which is widespread in Europe and Asia. Wood from Nordic pine trees is highly valued for its mechanical properties, and this quality material is characterized by evenly spaced annual rings. Pine is well suited for thermal modification as it becomes significantly more durable and stable through the process, acquiring a beautiful golden-brown tone.

The color of the wood changes over time

Thermal modification gives pine a naturally beautiful golden-brown tone. As with any wood, the surface of thermally modified pine will fade to a natural silver-gray color over time. This process starts immediately after the products are installed and can take a few months to several years depending on how much UV light they are exposed to. The durability of the boards is not affected.

If you would like to preserve the darker tone of thermally modified wood, we recommend oiling the boards once a year using a UV-resistant oil.

Deck maintenance. To oil or not to oil?

Thermally modified decking boards do not necessarily require surface treatment, but regular maintenance and oiling will refresh the appearance of your deck and make it easier to clean.

We recommend cleaning and maintaining the deck before the start of the summer season.

Lightly sanding faded boards will remove the silvery surface colour and restore the wood’s original appearance.


If you would like to preserve or change the tone of thermally modified wood, apply UV-resistant oil to the boards once a year.

If you would like to preserve the tone of boards that have turned grey over time, use colourless oil without a UV filter on the boards.

The oil should be applied only to clean, level, dust-free surfaces.

Recommendations for installing Benchmark thermo-pine decking

To make your deck last as long as possible, it’s extremely important to use the correct installation techniques.

For the substructure, we recommend using joists made from thermally modified pine with durability class 2 or thermally modified spruce with durability class 1. This way, the substructure will last at least as long as the decking.

Choose the PaCS Strip or the T-4, T-6 or TENI clip fixing to achieve a deck surface without any visible screw holes or screws.

By choosing decking boards with end-matching, you can minimize time and labor when installing boards of different lengths. The load-bearing capacity of the end-matched part of the decking is verified, and the two boards don’t necessarily need to meet directly over a joist.

Apply end wax to the ends of every decking board prior to installation to ensure a longer service life.
