FREQUENTLY ASKED QUESTIONS  

How is thermally modified wood produced?
The wood is heated to temperatures between 160°C and 230°C in a low-oxygen environment, often with steam to prevent combustion. This process alters the wood’s cellular structure, reducing moisture absorption and improving its resistance to decay.

Which wood species are suitable for thermal modification?
Common species include pine, spruce, ash, and beech. These woods respond exceptionally well to
thermal modification, making them versatile for both indoor and outdoor uses. 

Is thermally modified wood eco-friendly?
Absolutely. The process is chemical-free, and the extended lifespan of the wood reduces the need for
replacements, making it a sustainable choice.  

How does it compare to untreated wood?
Thermally modified wood outperforms untreated wood in stability, moisture resistance, and decay prevention. It also boasts a richer color and requires less maintenance.

Is it resistant to pests and fungi?
Yes, the heat treatment eliminates nutrients that attract insects and fungi, significantly reducing the risk
of infestation or decay.

Does it require special maintenance?
While low-maintenance, occasional cleaning and UV-protective coatings can help preserve its appearance outdoors.

Can it be painted or stained?
Yes, but its natural aesthetic is often preferred. If finishing is desired, it absorbs stains and paints exceptionally well.

How does it handle extreme temperatures?
Its stability ensures minimal expansion or contraction, even in harsh weather conditions.

Is it a sustainable material?
Yes, sourced from renewable forests and processed without chemicals, it’s a green alternative with a long lifecycle.

How does it react to water exposure?
With reduced moisture absorption, it resists swelling, warping, and rot, making it ideal for wet or humid environments.

Will the color change over time?
Outdoor exposure may lead to a silvery patina, but this doesn’t affect performance. UV-protective treatments can slow this process.

Can it be used structurally?
Not for load-bearing purposes, as thermal modification may reduce mechanical strength. 

What is its lifespan?
With proper care, it can last 25+ years outdoors, far exceeding untreated wood.
