Installation of thermowood facade

Thermowood is used in architecture in various fields. This material is used for the arrangement of building facades, floor coverings, and interior decoration. The developers of Thermowood technology are the Finns, although products of this type are also manufactured by the French and the Dutch. The main advantage is considered to be the environmentally friendly finishing of the facade of houses, since the material itself is made from natural wood with subsequent specific processing.

Types of boards for finishing facades with thermally modified wood

Special heat treatment of the raw material makes it possible to obtain a finishing material with high quality and technical properties. In production, mainly hardwood and softwood are used. A special feature of the process is repeated heating with steam and drying of the material to remove excess moisture. The color change across the entire texture of the material occurs due to gradual heating in the range of 140-200 degrees. As a result, thermally modified wood in facade design provides moisture resistance and no deformation. The classification of thermally modified boards depends on the temperature level at the last stage of processing:

• Class 1 - processing up to 190 degrees. The material is characterized by light tinting, acquiring low technical indicators;
• Class 2 - up to 210 degrees. The board is characterized by a dark color, resistance to decay, while having insignificant plasticity;
• Class 3 - up to 240 degrees. Characterized by high indicators of density, rigidity, resistance to any weather conditions.

There are many options for cladding facades with thermally modified boards. Often designers plan to cover the entire surface with products. But a combined style with brick, stone, concrete, glass will also look great.

Features of installation of thermally modified wood on the facade

The technology of installing facade panels made of thermally modified wood often involves a ventilated format. The work algorithm in this case is as follows:

• installation of the lathing - preferably also made of thermally modified wood;
• laying the insulation and creating a water barrier to protect against dampness and winds;
• installation of facades made of thermally modified wood.

The fastening is carried out so that there is a small distance of 3-4 cm between the material and the wall. Thus, cladding the walls with thermally modified wood will provide the required air circulation. At the same time, there will be no accumulation of moisture, since it is removed to the outside.

Installation of the facade cladding involves the use of special clips made of stainless steel. It is also important at the final stage to treat the surface of the material with specialized protective oils. In this way, the external wood cladding will remain in its original form throughout the entire service life.

What are the advantages of thermally modified wood facade systems?

What positive characteristics, in addition to environmental friendliness, does this facing material have?

Thanks to high-quality thermal treatment, the exterior decoration of the house with thermally modified wood has the following advantages:

• long service life - compared to ordinary wood, it increases by 15-20 times;
• low level of hygroscopicity - the increased density of the board does not allow moisture to be absorbed from the air, preventing the occurrence of rotting and corrosion processes;
• thermal conductivity - 25% less than that of boards made of ordinary wood;
• stylish aesthetics of the wooden facade - buildings with such facades look very presentable;
• stability of the structure - fastening the thermally modified board ensures the absence of deformations even under the most intensive use.

Working with such material is actually no different from working with other wooden cladding. Nevertheless, if it is necessary to carry out facade work with thermally modified wood, it is advisable to entrust them to experienced professionals. The construction company "Alba" is always ready to make a high-quality wood-like facade, as well as help with the selection and calculations of the material.
