Why prefer painted thermowood to regular painted wood cladding?

Real wood cladding has many functional benefits as well as a charming aesthetic. But if you are looking to make a bolder statement with your exterior, painted wood cladding might just do the trick.

Wood has many good qualities, and one is definitely its adaptability. You can use wide brushed boards for a rustic look, mix and match narrow profiles to create more textural surfaces, or opt for painted wood cladding to create bold and outstanding exteriors.

With real wood, the options are plentiful and painted cladding certainly allows you significant creative freedom.

Trend alert: black timber cladding

In recent years, we have seen more interest in the black wood cladding. It is a bold choice, indeed. But also modern, sleek and can bring out the buildings’ architectural features, unlike any other colour.

Black cladding is also a striking complement to other materials like concrete and can create a sense of depth and texture for external facades.

Why prefer painted thermowood to regular painted wood cladding?

So, if I opt for painted cladding then it doesn’t matter what kind of timber I use beneath? Not quite.

All wood products are a natural material and therefore affected by weather conditions. UV rays fade the colour on all wood species regardless of their modification. Wet and cold winters changing into hotter summers cause regular wood claddings to cup, bend and crack more compared to thermally modified wood which is a significantly more stable material choice for wooden cladding.

For a regular painted softwood cladding, one of the most usual issues is resin bleeding out of resin pockets. Thermally modified wood does not have this problem as during the heating process the resin is removed from the wood. In climates where there are long hot and dry periods thermally modified cladding is a possibility, whereas regular wood cladding is a high-risk choice there due to its behavior.

Therefore, choosing thermally modified wood for your painted cladding is a more durable and low-maintenance option. Unlike chemical impregnation, thermal modification enhances the wood throughout, not just the outer surface. The result is boards that are stable and durable in the long run.

Benefits of painted thermowood

1. Stability of material

With thermally modified wood, there are fewer dimensional changes compared to non-thermally modified wooden cladding. You can use wide thermo-treated cladding boards that stay nice and stable on the wall.

2. Durability

The thermal modification gives the cladding boards high durability. With thermally modified wood, paint can be added for aesthetical reasons, it is not needed to protect the wood.

For example, when you opt for Thermory Vivid Silvered series cladding, there is no need to repaint this cladding after some years as the wood itself is durable also without the paint. Non thermally modified wood needs paint for the protection of the material.

3. Less resin bleeding and better biological resistance

Thermally modified spruce and pine cladding have much fewer issues with resin bleeding out of resin pockets compared to not thermally modified spruce or pine.

Wood’s biological resistance increases as the nutrients in wood are modified during thermal modification, becoming less available to pests and microorganisms.

Thermory’s Vivid series provides outstanding colours with excellent stability

Thermory’s Vivid coated cladding selection is a high-quality solution that makes any building stand out from the crowd. The spruce and pine products undergo an intense thermal modification process that uses only heat and steam to give exceptional stability and durability.

The biologically durable, lightweight, easy-to-install boards are brushed to enhance their natural pattern. For a long-lasting finish, the wood is then coated with water-based paints that are environmentally friendly and have been tested in the harshest climates.

  • Vivid Opaque 10 has an average service life of paint of 10 years with Opaque covering paints
  • Vivid Translucent 7 has an average service life of paint of 7 years with Semi-Transparent paints
  • Vivid Silvered doesn’t necessarily require maintenance coating, just cleaning as the wood beneath naturally turns gray.
