5 tips for choosing wood siding for your home facade

7 min

A house with wood trim will always look attractive, only natural wood is a rather delicate material that is afraid of moisture, temperature changes, fire and pests, therefore it requires careful care. The one who sheathed the house with wooden clapboard knows well how much effort and money is required to maintain the finish in proper condition. To save us from these problems, wood siding was invented. It is made from polymers, metal and other materials, but it does not imitate wood well enough and has its own disadvantages. To combine the naturalness and beauty of wood with durability and resistance, it is better to choose wood siding for facade decoration. What is it like, and what to consider when choosing?

Types of wooden facade finishing

There are many facade materials on the market, many of them can be easily confused with each other, and some manufacturers are trying to achieve this by promoting their product under a louder name. The wooden facade of a house is usually understood as:

  • solid wood finish, i.e. wooden clapboard. The lining is made from different types of wood, which is well dried and treated with antiseptics. The material differs in type of profile, class and size. The main advantage is naturalness. In addition, the lining has a beautiful appearance, good heat and sound insulation qualities. There are more disadvantages: low moisture resistance, sensitivity to temperature extremes, a tendency to decay, the ability to maintain combustion, and pests love wood. The material is expensive, it will also be expensive to care for, so the industry began to look for a worthy replacement for wooden lining;

  • wood siding is made from wood waste, which is pressed under the influence of polymer additives. The technology allows you to give the product any color and texture. Of course, the material cannot be called completely natural, but it shows itself much better than wood. Wood siding does not rot, retains heat well, but cannot boast of high strength. Such a finish as wood can be considered only conditionally, but now it is often just such a material that is called wood siding;

  • Thermodecking material is made from solid wood under the influence of high temperatures and steam, as a result of which the structure of the wood and its properties change somewhat. The fear of moisture disappears, but the original appearance remains and even improves. The material does not decay, has high durability and good thermal insulation properties. The downside is the price you have to pay for the freedom from constant care and the beautiful look of the material for many years.

You can often hear about “wood siding” from sellers and on the Internet. It is a material made of vinyl, acrylic, metal, ceramics and fiber cement. It just mimics the structure of a tree. Some types of such siding are indeed durable, some look good, but when it comes to wood siding, we will only talk about wood fiber boards and Thermodecking.

Wood siding production

In the manufacture of wood siding, wood fibers are used, to which binders are added and the resulting mass is pressed under high pressure. Due to additives, you can get siding of any shade.

If you look at a cut of wooden siding, you can note that it resembles the more familiar MDF panels – the production technology is similar, and it allows you to get, though not natural, but completely safe material.

Sometimes you can find the name “wood-polymer composite (WPC) siding”. We are talking about, in fact, all the same material made from wood waste, modifiers and thermoplastic polymer. In the production of WPC, it is considered that the optimal ratio of wood and additives is 50/50. At the same time, the best strength characteristics are achieved and an attractive appearance is preserved. If more wood is included in the composition, then the material will be more fragile, if there are more polymers, it will lose its aesthetic qualities.

Siding can be sanded or embossed, it can be patterned by printing. Also, the boards are treated with paints and varnishes, covered with veneer, synthetic film or polymer materials. Hence the variety of appearance.

Wood siding: advantages and disadvantages

Since polymers are introduced into the composition of wood siding, a material is obtained that is devoid of many of the disadvantages of solid wood. Among the main advantages, we note:

  • resistance to moisture, snow, wind, sunlight and other environmental factors. Wherever wood has long begun to rot, wood siding retains its original appearance;
  • resistance to low and high temperatures, as well as temperature extremes. A solid mass is known to expand and contract depending on weather conditions. Siding is not subject to such changes;
  • strength and durability. In terms of strength, the material is not inferior to solid wood, and sometimes even surpasses it. The durability of the siding allows it to last longer than wood;
  • good indicators of heat and sound insulation, which are inherited from natural wood, which is part of the material;
  • attractive appearance. The technology allows you to form siding of any color and shape. It can successfully simulate a block house or have a flat profile;
  • safety. Although siding is not a completely natural material, it does not carry any harm to health;
  • ease of installation;
  • ease of care. It is unnecessary to treat the material with antiseptics, varnishes and paints.


  • wood siding cannot be called natural. This, of course, allows him to be more resistant to the external environment, but deprives him of the noble kind of wood;
  • flammability is lower than that of solid wood, but still quite high;
  • the price is much higher than that of wood, but if you take into account the costs of caring for the array, then the siding pays off in a few years.

Types of wood siding

Products of any shape can be obtained from a wood-polymer mixture, but the most popular are wooden siding of the following types:

  • block house – lamellas that imitate a natural frame and have a convex shape;

  • The false beam has a flat profile and is suitable for creating perfectly flat facades.

As for the color, it can be absolutely anything. Most buyers want to get the material that is as close as possible to natural wood, therefore siding from light yellow to dark brown with a characteristic wooden pattern has become especially widespread. For lovers of brighter solutions, a material painted in calm blue, green, white, burgundy colors and other shades is suitable. The technology allows you to obtain material with almost any desired appearance.

Sizes, as a rule, are standard, but many domestic manufacturers make concessions to customers, producing custom-made products. The length of the wooden siding board is 3, 4 or 6 m, the width can be 8-12 cm, 14-16 cm or 18-20 cm.The thickness is 1-2.1 cm.

Thermodecking material

Wood siding appealed to many buyers, but there was still a demand for something natural, yet durable. And such material appeared. This is Thermodecking material. Its production process is simple and complex at the same time:

  • preliminary drying of wood in special chambers at a temperature of 130-180 degrees;
  • increasing the temperature and pressure in the chamber, saturating it with water vapor, and sometimes with chemicals. The result is the decomposition of hemicellulose, a change in the structure of wood, the splitting of its fibers and the bonds between them. The material becomes less porous, which means it is more resistant to moisture, decay, decomposition and fungal attack, i.e. the biostability of wood is significantly increased;
  • stabilization of the obtained state by lowering the temperature or due to the action of certain chemicals.

The nuances of technology may differ from manufacturer to manufacturer, but the general benefits of Thermodecking remain the same:

  • safety and environmental friendliness. It is a natural material that is not capable of emitting harmful substances. If only steam and temperature were used in the production, then an absolutely safe product is obtained;
  • beautiful appearance. Wood not only retains its natural beauty, but also gets a more pronounced pattern. Even the simplest and cheapest species begin to resemble expensive types of wood;
  • resistance to moisture, so that rotting, swelling and mold are not terrible for the material;
  • resistance to temperature changes;
  • higher strength and durability than ordinary wood;
  • practically does not dry out and does not shrink.

Of the significant drawbacks, only one is the high price, which is explained by the complexity of the technology. If we consider that the facade will be decorated with durable natural wood that is not afraid of moisture and sun, then the high cost can be considered an investment.

WestWood Manufacturing Technology

The final wood qualities will depend on the technology and equipment used. Technologies such as VacuumPlus, PLATO, Bikos-TMT, Thermowood and others are used. For example, let’s take a closer look at WestWood technology, which is distinguished by the use of sufficiently high temperatures and a complete rejection of “chemistry”.

WestWood technology is developed and patented by Thermodecking Company. All the nuances of production and assortment can be found on the website https://trmd.ru… The company gives a 20-year warranty for all products, and the selected production technology allows you to be sure of the quality:

  • careful control over the quality of raw materials at our own procurement bases;
  • the use of modern equipment for sawing the massif;
  • high-quality drying, organized due to the smooth operation of the equipment;
  • the nuances of heat treatment. The wood is heated in chambers at a temperature of 185-205 degrees under increased pressure and in the presence of water vapor. The latter prevents fires and participates in chemical processes in wood. Drying takes several hours, and the whole cycle takes 30-36 hours. No chemicals are used, which allows us to speak of maximum environmental friendliness;
  • finished products are stored in modern warehouses.

Ash, birch, alder, pine and linden are used in the production. In addition to wall panels, this technology is used to produce decking, furniture boards, beams and other products. The company’s specialists can help with the choice of material, as well as with delivery and installation. In addition to high quality products, customers receive up to 9% discount on regular orders.

Thermal tree species

The choice of wood species depends on the requirements for performance and appearance:

  • thermo ash has gained the greatest popularity due to its excellent shade, high moisture resistance and geometric stability. According to the latest indicators, the material is superior to heat-treated oak and beech;

  • Thermos pine has a pleasant light color and fairly high softness. It is not used as a floorboard, but it is suitable for facades;

  • Thermolipa perfectly tolerates changes in temperature and humidity, has high wear resistance and is immune to biofactors;

  • thermo-maple tolerates high humidity, temperature changes and maintains a stable geometry.

Thermal alder is more often used for finishing baths, and thermal book and thermal oak are more suitable for interior decoration.
