LeParqueteur is Thermo Wood manufacturer


Thermo - Chocolate LeParqueteur is a patented brand of first class Thermo wood products of the holding Drewesina.ru Ltd. We have started the production of Thermo wood in 2014 on newly build workshop of the factory. Latest high-end vacuum equipment allows to manufacture the Thermo wood products within short terms and with premium quality. Annual production capacity is about 1000 m3 of Thermo wood.

The main factory is located in northern part of the Republic of Belarus providing convenient position to the European market and to sea port in Lithuania. We have subsidiary factories in 23 countries: Malaysia, Canada, USA, Brazil, India, Russia, etc., all subsidiaries have close location to logging places and trade terminals.

Optimization of work processes and individual touch allows to follow request of the most exacting customers. LeParqueteur is specializing in Thermo Ash , Thermo Pine and Thermo Spruce, but we are able to produce any species of wood by the individual orders of the customers.

We produce Thermo wood: decking, cladding, siding and flooring with any profile requested by the customers. Shipments of the orders are processed by our own professional specialists allowing to deliver the goods directly to the customers address in shortest time. We do not have minimum order quantity, we quote any batch you need. LeParqueteur provides patented “easy to use” own system of assembling of the decking and facade including fast hidden system of fastening.

About Thermo Wood


Thermo wood is thermally modified timber. This process has a permanent effect on the wood’s properties providing excellent durability, dimension stability and insulating qualities. Thermo wood has improved protection against water and decay, reduced warp and twist caused by moisture, sun and time influence. Thermo wood products keep a new-like appearance for a long time.

As a principle the heat treatment process can be done on all wood species.

The biological resistance against some (not all) micro-organisms and insects (termites) is improved. Shrinking and swelling is reduced up to 50–90%. Flexibility strength is slightly decreased as a result of the high temperatures, but it is not an issue in the real applications.

Technological process: The Thermo wood process consists of preliminary drying, controlled heat treatment with wet steam and in lack of oxygen environment and finally smooth cooling/conditioning of the timber. The whole process takes up to 7 days. The required time depends on wood species, width and initial moisture content.

Recommendations for the end use applications of Thermo wood LeParqueteur:

  • building components
  • finishing in dry conditions
  • fixtures in dry conditions
  • furniture
  • garden furniture
  • sauna benches
  • door and window components
  • cladding
  • outer doors
  • shutters
  • enviromental constructions
  • sauna and bathroom furnishing
  • flooring
  • garden furniture

What is Thermo wood?


Thermo wood is thermally modified timber. Thermo wood Ash before treatment and after. The treated wood is darkened in color.

What structure?


Propeties of Thermo wood


  • 01. Density

    Thermo wood has slightly lower density than untreated wood. The density decreases as higher treatment temperatures are used. Lower density provides better insulating parameters and lighter weight of the structure.

  • 02. Strength

    Thermo wood in some cases has lower strength values, but weight-strength-ratio is practically unchanged. Thermo wood has lower moisture content, and therefore the strength is higher compared to normal wood. The bending strength is reduced by up to 40% compared with normal treated wood due to areas around the defects. However the wood treated with lower temperatures of around 190°C for 4 hours has far less difference in bending strength and not an issue in real applications.

  • 03. Emissions

    Thermo wood has lower emission compared to untreated wood and provides heathy ambience for the human beings. Total amount of Volatile Organic Compounds was reduced up to 55-82 % by the heat treatment. Take care of yourself and grab healthy life with Thermo wood!

  • 04. Screw holding strength

    The major impact on screw holding strength comes more from the general difference in wood density than heat treatment itself. In lower density material the results are better when pre-drill holes were used.

  • 05. Compression strength

    The rail compression strength according to tests with heat treated timber at 195°C for 3 hours is improved about 30% gained over normal kiln dried timber. The test pieces in this study had been submerged in water before testing. Compression strength is mainly dependent on the actual density of the wood. From tests it can be proved that the heat treatment process has no negative effect to the compression strength values. Impact strength value of Thermo wood is decreased in comparison to normal kiln dried timber (about 25%).

  • 06. Shear strength

    The strength properties are reduced in radial tests from 1 to 25% and in tangential tests 1 to 40%. However in lower temperature treatment there is a very little effect on both radial and tangential tests (1 to 20% decrease). The splitting strength is reduced by 30-40% and the deterioration becomes slightly worse with the higher temperatures..

  • 07. Hardness

    The hardness value improves as the intensive heat treatment temperature level increases, however the change in relative terms is very small, therefore giving no effect in practice.

  • 08. Moisture content

    The heat treatment of wood reduces the equilibrium moisture content. When higher temperature treated goods are exposed to over 90% humidity the moisture content can be 40-50 % less than normal treated.

  • 09. Stability

    The overall stability of heat treated timber can be viewed in many positive aspects. As the general equilibrium moisture content is somewhat lower, the tangential and radial swelling decreases significantly. Due to the dimensional stabilization of the wood, re-cutting of the material to thinner sections gives positive results with reduced amounts of cupping and general movement.

  • 10. Permeability

    Water uptake of heat treated timber is important in such products as window units. Samples were dipped in water and then kept in room with relative humidity of 65% and 20 °C and periodically weighed over period of 9 days. The water uptake in heat treated spruce was 20-30 percent less than normal treated wood. The untreated spruce gained a moisture content of 22% while after the treatment at 195°C it was about 12% and after the treatment at 210°C it was 10%.

  • 11. Thermal properties

    The tests have shown that the thermal conductivity of Thermo wood is reduced by 20-25% compared with normal treated softwoods. Therefore the material has good advantages when used in applications like external doors, cladding, windows, sauna materials.

  • 12. Biological durability

    The biological resistance showed very good durability depending on the treatment temperature and time. To modify the wood to the class one (very durable) temperatures of over 220°C are needed, and to gain class 2 (durable) temperatures in the region of 210°C for 3 hours gain the best results.

  • 13. Resistance to insects

    The results of the tests found that Thermo wood has better resistance to all types of insects, including termites etc

  • 14. Weather resistance without surface treatment

    Rain & Sun: Against natural weathering Thermo wood takes about half the moisture content compared to untreated wood, this difference remains after five years of outside exposure. Thermo wood shows better ultra violet resistance compared to standard wood. Surface treatment is recommended to get even better result.
