Why choose Benchmark Thermo-Spruce for your terrace decking?

  • If you prefer rustic natural-looking wood but want premium durability at the same time, terrace decking made of Thermory Benchmark Thermo-Spruce is the one for you.
  • Thermal modification makes spruce a wood material of the highest durability class (class 1, 25+ years) which will adorn your terrace for decades to come.
  • The moisture absorption capability and rate of the wood is reduced as a result of thermal modification, in turn causing less moisture-induced deformation.
  • Thermal modification adds a beautiful golden brown tone to spruce.
  • In addition to being durable, our thermally modified spruce is environmentally friendly, as thermal modification is chemical-free and the waste generated is not harmful to the environment.
  • We offer thermally modified spruce that bears the NORDIC SWAN ECOLABEL. This means that the wood originates from responsibly managed forests, is free of chemicals and is extremely durable when used outdoors.

Spruce is less resinous

The common spruce (Picea abies or Nordic spruce) is a coniferous tree of the pine family in the genus Picea, widespread in Europe.
Without any treatment, spruce has almost white wood, is lightweight and soft and has medium mechanical properties. Spruce splits more easily than pine but it is less resinous. Spruce is very well-suited for thermal modification, becoming significantly more durable and stable thanks to this process and acquiring a beautiful golden brown tone.

The colour of the wood will change over the course of time

Thermal modification makes the tone of spruce wood a beautiful golden brown. A brushed finish will further highlight the depth and pattern of the wood.

As with any other wood, the surface of thermally modified spruce will acquire a natural silver grey colour 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 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.

Five recommendations for installing decking made of Benchmark Thermo-Spruce

The right installation techniques are extremely important to make your deck last a long time.

  • For the substructure, we recommend using joists of thermally modified spruce of durability class 1. This way, the substructure will endure as long as the decking.
  • When installing Thermo-Spruce decking, make sure that the heartwood side of the board faces down.
  • Choose the PC or TENI clip fixing to get a deck surface without screw holes and visible screws.
  • By choosing decking boards with matching tongue-and-groove ends you can install boards of different lengths with the least possible time and labour input. The load-bearing capacity of the tongue on end-matched tongue-and-groove decking is verified and you do not have to join the boards directly over a joist.
  • Apply end wax to all ends of the decking boards before installation to ensure longer service life.
