Nordic pine ThermoWood®

ThermoWood® pine honey

The heat treatment of wood at industrial level under the trade mark ThermoWood was developed in Finland. The wood produced by this thermal process has undeniable advantages against common and exotic woody species. Regarding the ThermoWood material, the internal structure as well as physical features are changed due to heat treatment. The change in features is mainly caused by thermal degradation of cellulose, lignin and hemicellulose (sugar chains). The heat treatment removes resin, and so there are not resin leaks or filled resin galls on the surface. When applying a sufficiently high application temperature, the treated wood shows excellent rotting resistance (biological resistance grade 2) as well as wood insects resistance without using any chemicals. If hemicellulose is decomposed, the substances nourishing wood – decay fungus are also removed.
The wood is impregnated with penetrating and adherent final coating including its UV protection. The coating provides a flexible, long – lasting matte color of honey and graphite grey.

Tropical wood

Garapa

Apuleia Leiocarpa – also called Brazilian Teak – is a hardwood with natural weather resistance. This wood species comes from South America. It has far better features than more well-known Bangkirai or Massaranduba. It is characterized by good stability, strength and durability. Garapa is a very popular exotic species worldwide. It is used for the production of deckings, building constructions and exterior furniture. The specific weight of Garap at 12% moisture is about 850 kg/m³. The color of this wood is golden or yellow with different tones. Over time, the color changes its tone from reddish to grey due to UV light. A very desired feature is pigment release. The fibers are flat, the structure is cohesive and smooth. Color elution appears to a very small extent.
The tropical wood is treated with colorless, hydrophobic, impregnating oil on the linen basis. Regular oil treatment ensures preservation of the original color tone of the wood. Oil also affects closing and opening of the pores and helps keep the correct wood moisture.

Norway spruce

Picea abies is a wood species without color differences in its core but it has distinctive annual rings and a regular structure. The structure is white or slightly yellowish with a slight gloss. It weighs 470  kg/m³ at 15% moisture (moisture of naturally dried wood). The wood is quite soft but strong enough, flexible and durable.
The battens used for furniture are treated with a three-layer wax coating. It has a biocidal effect and ensures a long-term wood protection against rotting, unfavorable weather conditions. It also ensures color fastness and highlights wood patterns. We usually use a tone of light walnut.

Acacia

Robinia pseudoacacia is exceptional wood due to its shape and volume stability, high hardness, elasticity, low mechanical wear, water resistance, and last but not least its beautiful tones and high gloss. Acacia is the most durable wood among all European woody species. Unprotected and unimpregnated wood can endure for several decades. Acacia wood, as one of few, contains essential oil repulsing pests, and is also highly resistant to rot and mould. This feature is used wherever it comes into contact with water. Acacia wood is yellow-brown, heavy, hard (density is 750  kg/m³), solid, very suitable for contact with other materials. One of the important features of acacia is its gradual greying that is often welcomed by customers for its glossy and slightly silver tone. Wood greying is caused by elution of color due to its surrounding environment.
Despite excellent features of natural acacia, it is treated with a colorless hydrophobic oil on the linen basis. Regular oil treatment ensures preservation of the original color tone of wood. The oil also partially improves the physical features of wood. It affects closing and opening of the pores and helps keep the correct wood moisture.

Oak

Quercus petraea has excellent features – it is very hard, strong, tough, flexible, durable and very resistant to mechanical abrasion and scratches. What is interesting the wood is also used in water engineering as its positive features are improved when placing the wood in water. Oak wood has pores arranged in a circular position. The pores form well-visible grooves on the longitudinal sections that may be up to several tens of millimeters long. Its wood rays on the radial section are very distinctive. They form a glossy surface called mirrors. The naturally dried oak weighs about 680 kg/m3. Thanks to the fact that oak wood has a high content of tannins, it is resistant to rot and pets. When considering our wood species, it has the longest resistance not only to weather conditions but also to changes in moisture and drought.
The battens used for furniture are impregnated, glazed and applied by high-pressure spraying that has a biocidal effect and ensures a long-term wood protection against rotting and unfavorable weather conditions, and also color fastness. We usually use a tone of teak.
