Modified wood
Modified wood is treated wood that has an extremely high durability. The treatment can consist of a thermal modification, a bio-based modification or a modification with oil.
After the treatment, the needle wood acquires the appearance and properties of tropical hardwood:
- Environmentally friendly: When we modify wood, what we are doing is treating a non-sustainable type of wood in order to extend its lifespan. This does not involve chemical agents, which is the case with wood impregnation, for example. In addition, the wood is often sourced locally, which means that significantly less pollution is involved in transport. These factors make modified wood an environmentally friendly and environmentally responsible choice.
- Higher sustainability class: Thanks to the modification process, the wood is significantly less sensitive to moisture, wood rot, fungi and insects. Non-sustainable types of wood therefore have a much longer lifespan that is comparable to that of high-quality hardwood. In addition, modification can mean that wood with a durability class 4 or 5 is raised to a class 1 or 2. As a result, modified wood can easily last 25 to 30 years.
- Stable and light: Modified wood is extremely stable, because the moisture has largely disappeared from the wood. One logical consequence is that this type of wood weighs a great deal less. The combination of stable and light make this wood perfect for cladding.
- Various uses: Modified wood is extremely versatile, and is the perfect material to use as facade cladding, decking for terraces, fence boards for gardens, joinery and window profiles. In addition, the modified wood can easily undergo processing, such as sawing and milling.
- Maintenance-friendly: Modified wood does not in principle require maintenance, and no longer needs to be stained or coated, making it an interesting alternative to impregnated wood and tropical hardwood species. If you do opt for a finish, it will have a greatly increased service life – up to 15 years with guarantee – which will significantly extend maintenance intervals.
- Warm colour: Modification also gives the wood a beautiful, warm colour. Modified pine and spruce, for example, will take on an almost nutty colour that is very aesthetically pleasing. In addition, modified wood ages very evenly, which gives it a luxurious look.

Bio-based modified wood
Bio-based modified wood undergoes a process that strengthens softwood using an organic liquid.

ThermoWood®
The ThermoWood® range consists of durable softwood that has been thermally modified.

Royal impregnated Scandinavian pine
Scandinavian pine is extremely suitable as a sustainable cladding that can withstand wind and weather.

Heat treated wood
Heat treated wood has been made more durable and has better properties than tropical hardwood.
