1/ Where is the company established?

LDCwood has its production site in Ostend, Belgium.

2/ Does your products contain chemicals?

Our ThermoWood® products are 100% natural and contain no chemicals. The thermal treatment only uses heat, steam and water.

3/ Can our ThermoWood® application also be installed by LDCwood?


4/ Can the ThermoWood® be ordered in any dimensions, or do you only deliver standard sizes?

At your request, ThermoWood® can be processed into a profile chosen by you.

5/ Do you also export to other countries?

Until now, ThermoWood® could only be imported from other countries. As the first Belgian producer of ThermoWood®, LDCwood will serve the European market.

6/ Do you have your own stock?

Yes. That is precisely why we can respond quickly to the demand of the customer and reduce the delivery period.

7/ How many ovens do you have? And what is their capacity?

We have 6 kilns of 40m2 each.

8/ Is your ThermoWood® FSC® or PEFC certified?

The wood used by LDCwood for the thermal modification comes 100% from sustainably managed forests. Depending on the type of wood, LDCwood's ThermoWood is therefore FSC®, PEFC or OLB certified. (PEFC/07-31-24 | FSC® C001899)


 1/What is ThermoWood®? Can you give more information about the process?

ThermoWood® is the result of the thermal modification of wood to a higher durability class. Thermal modification is a controlled pyrolysis process, whereby the wood is heated (>215°C) in a low-oxygen environment in order to enlarge the durability class of the wood. Negative characteristics of wood such as fungal growth, moisture problems, degradation due to insects, expansion and shrinkage, etc. are reduced to a minimum or even fully eliminated thanks to this process.

2/ To which types of wood does the ThermoWood® process apply?

In principle, the method can be applied to every type of wood. Initially LDCwood is focusing only on the production of ayous and fraké – wood types from Cameroon, West Africa –, ash, pinewood and poplar.

3/ What is the maximum thickness of ThermoWood®?

  • Appearance and design of wood

  • Produced from legally managed forests (European Timber Regulation)

  • Production process without use of chemicals

  • Healthy


1/ What is the added value of the International ThermoWood Association?

The objective of the International ThermoWood Association is to promote the use of ThermoWood®. Together with the members the association seeks both to guarantee quality and to do further research on the use of thermally treated wood. These members undergo an annual inspection where the quality and proper compliance with the process are checked. In this way the quality of ThermoWood® is guaranteed.

Thanks to the International ThermoWood Association, all products sold under the ThermoWood® trademark possess a technical and ecological quality guarantee.

LDCwood has been a member of the International ThermoWood Association since 2017.

2/ Do you have a product certification?

The LDCwood production process is a patented Finnish process under the control of WOOD.BE. In the certificate of conformity, the durability class is determined for the most common types of wood that LDCwood modifies.


1/ Is it necessary to maintain ThermoWood® products? If so, how often? And what are the differences in maintenance compared to standard wood?

Every product that is applied in an outdoor environment requires maintenance. And although some products simply cannot be maintained, wood can still look the same even after many years thanks to easy maintenance.

ThermoWood® was already thermally treated once, and can therefore already count on more benefits than normal or untreated wood. For example, with ThermoWood® you will encounter fewer problems with insects (holes), fungal growth, decay, expansion, etc.  Maintenance of ThermoWood® is thus recommended, but is required with less frequent regularity than with untreated wood.

The regularity with which maintenance is required, depends on the exposure to UV rays, the general weather conditions or the colour of the wood (more pigment means less maintenance). We can stain your ThermoWood® colourless or black at your request.

2/ What happens if maintenance or the surface treatment is not done?

If ThermoWood® is not maintained, the wood can crack on the surface or the colour can turn grey due to exposure to UV rays. Yet the lack of maintenance has no effect on the positive characteristics that are the result of the ThermoWood® treatment.

3/ In which zones can ThermoWood® products be applied?

Depending on the type of wood, the following applications are possible both indoors and outdoors: (facade) covering, terrace, around swimming pools, sun protections, flower box, parts of doors and windows, parquet and solid floors, panels or partition walls, sauna cladding and furniture, ...

4/ How do I have to maintain my ThermoWood® product?

Before you begin any treatment, we recommend washing off all dirt. Afterwards you can simply apply varnish/oil with the use of a brush or roller. For all of the information about maintenance and the cost thereof, please contact our representative.
