Thermory Wood Decking benefits:
Benchmark series
Attractive decking that stands the test of time
Timeless, functional, durable and environmentally friendly. These are all qualities that a decking product should offer – and that’s is exactly what our Benchmark Series is all about.
Each board is thermally modified, resulting in environmentally friendly products with a natural beauty that lasts for generations.
Depending on the profile, Benchmark decking 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.

Why thermally modified wood?
Thermally modified wood is the most reliable option if you’re looking for a durable and dimensionally stable material for outdoor conditions. Due to the high temperature, the structure of the wood changes, which significantly improves the durability and resistance to weather conditions.
- The biological resistance of wood increases as the nutrients in the wood become more difficult to reach for wood pests and molds.
- The moisture absorption capacity and speed of the wood decreases, resulting in reduced moisture deformations. 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 smaller internal stresses in wood, which significantly reduces material consumption during construction.
- Improves the thermal and sound insulation performance of wood.
- Heat treatment also gives the wood a delightful darker tone.
- Thermal modification is chemical-free.
First-rate products deserve exceptional installation solutions.
Our highly rot-resistant real wood products are easy and efficient to install. We’ve developed a number of innovative installation systems and methods that offer solutions to some of the industry’s most pervasive problems. More importantly, they’ll save you time and money.


Deck maintenance. To oil or not to oil?
Thermally modified decking boards don’t require surface treatment. Like any wood, the surface of Thermory products will naturally turn silver-gray over time – this process starts immediately and can take anything from a few months to a few years depending on the levels of UV radiation they’re exposed to. However, this does not make the wood less durable. If you want to preserve the wood’s original color, or change it, you can do so by treating the products with a UV-protection oil every year.
- 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.
