The aesthetics of the classic log home still "attracts" those who acquire real estate outside the city. Mentality, traditions, roots - there are many terms explaining why a log house does not lose its popularity and is so common in the “village” landscape. But besides the peculiar beauty (which can be repeated by trimming the facade with panels), a wooden house has another important advantage - ecological cleanliness and unique microclimate. These advantages, and many others, are inherent in the modern version - a log of rounded logs.
A round log house successfully combines tradition and modern technology.
Classical technology The log house is purely manual work, which only experienced scissors can do. And there are few such specialists, and their services are expensive. Regular logs differ from each other, have different diameter sizes in the direction from the butt to the top, and they must be properly folded. In addition, all technological grooves are selected manually, and the duration of shrinkage is the longest for all types of wooden houses. And although the initial assembly takes place not at the customer’s facility, but at the manufacturer’s site, the timeframes from the start of building a house from a log to installation are quite significant.
Manual chopping and possession of such a tool is no longer a profession, but the art of
log cylindering allows you to produce a standardized material on an industrial scale with which you can work using modern construction methods:
development of a package of documentation - drawings, specifications, technological charts, instructions for installation, etc.;
reasonable and "clear" cost calculation;
production in the workshop of all the necessary elements with technological holes, studs and grooves
transportation to the site;
on-site assembly of the structure in full compliance with the project.
And despite the fact that the rounded log is more expensive than the “wild” one, the houses are cheaper because it reduces the share of manual labor and assembly time.
Another advantage is that the crowns adjoin each other due to accurate sampling of grooves and bowls on modern machines. Therefore, with an equal thickness of the walls of the house from the rounded logs warmer.
Warming of the rims is also put on an "industrial" basis
In addition, when logging the logs, the "looser" upper layers of the wood are removed and get a smooth surface that does not need additional machining.
But that's not all. A rounded log, like a bar, can be different in terms of humidity and structure.
There are three types of logs, depending on the method of its manufacture and storage conditions:
This is probably the most common option.
Usually, a rounded log is kept under natural conditions for at least a month, therefore it is not as “wet” wood as immediately after cutting. Shrinkage of such a house is not higher than 10%, but in reality it is even lower if the tree was cut in the winter in the northern regions. Although in absolute terms, this figure is quite large (depending on the height of the walls), and the house should be 4-6 months old before finishing works.
A log of natural humidity should be winterized and can reach “condition” even outdoors
On our site you can familiarize yourself with the most popular projects of houses made of logs from construction companies, presented at the exhibition "Low-Rise Country".
There are different methods of drying, but they have a similar initial stage - first they make a “rough” cylindrical log.
Cutting of the mounting groove and the compensation seam can be carried out before drying or after - depends on the specific routing. But it is considered that it is better to do this “before” in order to reduce the forces of internal tension.
Then the logs are placed in a chamber, where in a short time excess moisture is “driven out” of the wood. Drying options are several: convective, infrared, vacuum, microwave. After that, the intrinsic moisture content of the wood does not exceed the level of 20-22%, and some manufacturers announce 6-12%.
Drying chambers are modern production using advanced wood processing technologies
The most advanced drying process is considered to be a microwave oven first of all the core dries out, which shrinks and "tightens" the outer annual rings. When this occurs, the density increases, and the risk of cracking is significantly reduced.
After drying, the log is cut and processed under the "finishing size".House designs from the rounded chamber drying chamber are more expensive, but they do not go through the shrinkage stage, which significantly reduces construction time.
In this case there are also different technology options.
The easiest way is when additional semi-circular segments are glued to the central part in the form of a glued beam. Most manufacturers even refer this type to the “glued laminated timber” category, since the inter-ring joint passes along the thorn-groove principle.
Glued laminated timber can look like a rounded log
On our site you can find contacts of construction companies that offer the service of building houses from Rounded logs. Directly to communicate with representatives, you can visit the exhibition of houses "Low-rise Country".
The following method differs from the previous one in the manufacturing sequence. First, a blank is glued from dry lamella boards, which is then “rounded” and the profiles of the locks are cut.
This is what a glued log looks like with a classical connection scheme
The third way is the domestic development of Vologda wood processing specialist Vasily Kazachkovsky. First, the log is rounded "in the rough", then cut into billets, dried to 12%, planed and glued together anew. Then subjected to "finishing" processing. But the main nuance - the width of the glue line of each lamella does not exceed 55% of the surface, thereby retaining the "breathing" properties. The central part can be a solid timber or glued with horizontal seams, which in any case does not violate the natural gas permeability inherent in the tree.
Kazachkovsky glued log scheme: 1 - central timber, 2 - side slats, 3 - adhesive bonding
Overall advantage of all technologies the fact that in the end get a non-shrinking material that allows you to build a turnkey log house in one season.

Previously, craftsmen chopped a wooden house literally to the “eye”, relying on experience and skill. But it was much simpler for them - the water and heating pipes did not pass through the walls, and when an electrician appeared, the wires were laid in an open way.
Laying networks in a wooden house is much more complicated than in a brick building
Now they are building on the basis of a package of project documentation, and only depends on workers build quality and technology compliance. And then what will be the house of the logs is determined by the professionalism of the designer. And unlike the design of buildings made of brick, building blocks or CIP panels, this is exactly what wood construction specialists should do.
Wood is a “living” material, and the house is in constant motion.
If a log of natural moisture is used, the house shrinks considerably during the first six months. Even then, the processes do not stop completely, but last for several years, but much more slowly.
And this process should not be confused with draft:
Shrinkage - change in geometrical dimensions due to drying or compaction of building materials.
Draft - settling of the house due to compaction of the soil under the weight of the structure.
If a chamber drying log, then everything is not simple - it must “adapt” to the operating conditions. And since each method of drying has its own characteristics and the output of the wood is different indicators of its own moisture, this factor must be taken into account.
With the experience of living in the house can be found on the video:
But later, after the shrinking process, wooden the design will be "moving" - to respond to seasonal fluctuations in humidity levels. Therefore, all attachment points must have a certain degree of freedom, and a house made of a rounded log must behave like a single “organism”.
The changes in the humidity level of the air on a laminated log are least of all affected. But this is the most expensive category in this class. Shrinkage of laminated wood is also insignificant, so the guarantees are higher that the construction of the house will behave more predictably, and this will not affect the interior decoration and communications.
But in any case, wooden houses should have a project developed by “narrow” specialists.
Houses made of round logs, the projects and prices of which are presented on the Internet have a fairly wide range of prices.
Clearly what and how much you can see on the video:
If we speak in general, you can find sentences on 7000 -8000 rub. per 1 m2, but in this case we are talking about building a “box” under the roof on a ready-made foundation, the price of which is not included in the estimate.And finishing works, including windows and doors, are carried out after shrinkage, and they are paid separately.
If the material is a rounded log of pine of natural moisture, the cost of the project "turnkey" on average costs from 25 to 30 thousand rubles. Approximately the same amount will cost a house of glued logs of domestic production, but already "for finishing", and for a complete set of "turnkey" you have to pay twice as much.
To the house "turnkey" it remains only to bring furniture
The most expensive segment in terms of price per square meter is home class " premium "from Finnish glued logs. Although the cost per square meter turnkey more than 70 thousand rubles. - this is more a matter of prestige, not quality assurance. Domestic winter forest logging of conifers, such as Arkhangelsk pine, Altai cedar or larch, is valued all over the world.

Houses made of wood, and in particular from logs, confidently hold their niche in the market of private housing. Methods of procurement and processing of materials are changing, new technologies of construction appear, but the demand for wooden houses will not disappear for a very, very long time, as for environmental friendliness and beauty there is no analogue for them yet and is not expected.
