Round timber: characteristics, reviews. Houses from the rounded bar

Rounded timber is popular among builders and private buyers because it can be used to assemble a classic Russian log cabin, which was erected by our ancestors from a chopped log. New technologies make adjustments to the workpiece and the characteristics of the above material. The construction process is therefore more technologically advanced and faster. The house turns out with even crowns, and in its walls there are no cracks.

Main characteristics

Russian felling

The internal space of the house will be protected from cold air and extraneous noise if the walls of the building are erected from a rounded log. It has heat and sound insulation properties. According to this parameter, the described material occupies a leading position among analog solutions.

Mentioned important advantages of the house are due to the natural properties of wood.The freezing temperature will depend on the diameter of the log. If this parameter is 160 mm, then the freezing temperature will be -36 ° C. Such walls can be compared to a brick wall of 630 mm. With an increase in diameter to 200 and 220 mm, the freezing temperature becomes -48 and -54 ° C, respectively. Walls with such parameters can be compared to brick ones, which are 1000 and 1130 mm thick, respectively.

Round timber is offered for sale with a diameter of up to 260 mm. Usually products are shipped in processed form. This allows you to create a finished house on the construction site. In logs, structural elements are performed in advance, namely:

  • grooves;
  • locks;
  • openings for doors and windows.

Among the main characteristics should also highlight the working height. It determines how many crowns will need to be laid to ensure the vertical size of the house. The working height is determined from the top point of the log cross section to the top of the inter-ring groove. It depends on the type and width of the groove.

Logs can have a Finnish or lunar profile. Round timber has a certain length. The standard value is 6 m.However, modern production can produce materials up to 13 m in length and more. The cubic capacity depends on the diameter and length. The 13th log with a diameter of 24 cm will have a volume of 0.72 m3.

Cutting Information

Quite an important structural element is the size of compensation kerf. With shrinkage and drying in the log cracks appear. Compensation cut allows you to send them to the area of ​​the upper crown. This ensures additional protection of walls against moisture and cold bridges.

The damage from cracking is minimized if the Finnish profile is used to improve the fit of the crowns. It provides additional protection of the lower log from cracking due to geometric cuts. If to carry out thermal calculation, then the rounded timber with a Finnish profile of 22 cm is equivalent to the traditional moon slot of 28 cm.

Characteristics of logs depending on the type of wood

Numbered logs

The most suitable species for round logs are pine and larch. The first allows you to get a beautiful texture, low thermal conductivity and high strength. If you apply larch, you will be able to provide a higher resistance to external factors and temperature changes.

Such products possess high strength characteristics. The main disadvantage of this material is the high cost. Cubic meter can be purchased for 12 000 rubles. If you make a comparison with a pine log, then for the same amount it will have to pay about 7,000 rubles.

When houses are lined up from round timber, larch is often used to form several lower rims. The rest of the building is collected from pine logs. In this case, it is possible to achieve the optimal combination of cost and quality.

Reviews of different types of logs

Grooves in the log

By type of processing, a rounded log can be divided into chopped and, in fact, rounded. In the first case, the cylindrical shape is attached to a hand planer. This tool is used for cutting bowls. This type of log, according to consumers, is suitable for those who prefer the natural style of the Russian izba.

For the construction of houses made of round timber material is used, which is processed on a special machine. From the words of consumers, this allows us to achieve the perfect geometry and high accuracy of the seats, which are the bowls and grooves.By type of drying products can be divided into natural moisture logs and thermal logs. The first are represented in the domestic market in a larger volume. This is due to the fact that to ensure uniform drying is very difficult, in addition, it affects the cost of products.

Considering the characteristics of the rounded timber, you will notice that it can be represented by a heat log, or artificially dried. At the same time it is possible to achieve a moisture content in the range of 20%. The products may be based on different breeds. Each enjoys a certain popularity.

The most common pine. She ranks first. Following are:

  • spruce;
  • cedar;
  • larch.

The most expensive are hardwood logs. After reading the reviews on the rounded timber, you will understand that the grooves in the products can be located along, diagonally or across. For creation of non-standard forms the diagonal arrangement of a groove is used. This allows you to form, for example, bay windows.

What to choose - timber or rounded log?

Wooden house

Profiled timber is a product made from a single log.On the sides there are connecting elements, thanks to which the builders have the opportunity to assemble the wall without the use of insulation. Both solutions described in the article are environmentally friendly and are made of the same material. Comparison can be made on several factors, among them:

  • shrinkage;
  • esthetics;
  • durability;
  • profitability;
  • the need for caulking tools;
  • thermal quality;
  • ease of installation.

Shrinkage comparison

Profiled bar gives a slight shrinkage in the range of 4.5%. The house shrinks faster and more evenly due to the special construction of the timber. The cons of such material, according to professionals, almost none. Caulk walls are not required at first, which distinguishes such a building from the log.

Comparison of the density of the crowns

Wall assembly

The sides of the timber, which are cut during the production process, ensure the most intimate contact between the crowns and guarantee the absence of drafts. If you still have not decided for yourself what is better - a bar or a round log, you should compare them. The latter gives a greater shrinkage - 10%. Among the minuses should highlight the need caulking cracks in non-compliance with technology.

Comparison in appearance

House project

As for aesthetics, the shaped products crack less in comparison with a rounded log. But such walls will need additional finishing and processing. If you decide to use a rounded log, the appearance of the building will immediately be excellent. Additional finishing is not required. But when dry, the walls crack more.

Comparison of houses from profiled timber and round logs

Profiled timber

Projects of houses from rounded timber can be completely different. Some of them are presented in the article. But between the materials described there should be another comparison regarding thermal properties. In rounded products, thermal insulation is good, but slightly worse than that of a profiled bar. The latter, with a size of 200x145 mm, makes it possible to achieve thermal insulation, which is equivalent to a rounded log with a diameter of 340 mm. This material is more durable in comparison with products of a semicircular form. Profiled zapily allow you to protect the house from moisture, which eliminates the destruction of wood rot.


Wooden house plan

Rounded logs are widely used in construction.They are processed by a special technology, which allows to achieve the same thickness along the entire length. The maximum transition can be 1 cm. Such logs have intervening grooves that allow for ease of installation. The width of the groove is usually 2/3 of the diameter. This size ensures the preservation of natural texture and thermal qualities.

On sale today you can also find a thermowalder. It is a sawn timber, based on a thermally modified timber. The production technology involves the heat treatment of the material, which is accompanied by high temperature drying in airless conditions.
