NATURAL, BEAUTIFUL AND DURABLE
Thermally modified spruce from our Benchmark range gives your facade a natural rustic look with visible knots that will last for decades. Spruce wood acquires excellent weather resistance and biological durability as a result of thermal modification as well as a naturally beautiful light golden tone.
Thermally modified wood is a natural, durable and environmentally friendly choice.
Very good durability and beautiful knots
Why choose Benchmark Thermo-Spruce?
- Choose wall cladding made of Benchmark Thermo-Spruce if you prefer rustic-looking softwood but also require premium durability.
- Thermal modification makes spruce a wooden material of the highest durability class (class 1) that will adorn your facade 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.
- 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.
Additional options for flawless finish and easy installation
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.
Wall cladding maintenance To oil or not to oil?
Thermally modified wall cladding does not necessarily require surface treatment. However, if you would like to preserve or change the tone of thermally modified wood, we recommend oiling the boards before installation using UV-resistant oil and repeating the oiling process every 3 years. The oil should be applied only to clean, level, dust-free surfaces. Before applying oil to the whole cladding, test it on a small piece of wood using a small quantity of oil. Observe the oil manufacturer’s instructions.
Three recommendations for installing Benchmark Thermo-Spruce wall cladding
The right installation techniques are extremely important to make your panelling last for a long time.
- For the substructure, we recommend using joists of thermally modified spruce of durability class 1. This way the substructure will endure just as long as the panelling itself.
- By choosing wall cladding with matching tongue-and-groove ends, you can install boards of different lengths with the least possible time, material costs and labour input. Any two boards do not necessarily have to meet directly over a joist.
- When using screws for installation, screw heads must not be forced too deeply into the wood. The screw heads must be almost flush with the wood surface to avoid water penetration.
