Frequently asked questions
Thermally modified wood, also known as thermowood, is wood that has been treated at high temperatures (typically between 160°C to 215°C) in the absence of oxygen. This process alters the chemical and physical properties of the wood, making it more durable and stable.
The production process involves heating wood in a controlled environment (without oxygen) to avoid combustion. The high temperatures change the cell structure and chemical composition, resulting in enhanced properties.
Main benefits include increased resistance to decay and fungi, reduced moisture absorption leading to better dimensional stability, and a darker, richer color.
Yes, it is particularly well-suited for outdoor use due to its enhanced durability and resistance to decay and weathering.
Yes, it’s considered an environmentally friendly option because the process uses heat instead of chemical preservatives to enhance wood’s properties.
It requires minimal maintenance compared to untreated wood, but like all wood, its appearance can change over time due to exposure to sunlight and weather, and it may benefit from periodic cleaning or application of protective finishes.
The process can slightly reduce the strength of wood due to the breakdown of hemicelluloses during heating, but the wood remains strong enough for most construction purposes.
Most wood species can be thermally modified, but the results can vary depending on the wood’s original properties. Softwoods and some hardwoods are commonly used.
Yes, it is generally more expensive due to the specialized treatment process, but the cost is offset by its longer lifespan and reduced maintenance needs
With proper installation and minimal maintenance, it can last 25 years or more, significantly longer than untreated wood.
