Log felling technology in Canada. Canadian felling: technology and price

Let's not hide that one of the most popular construction technologies wooden houses is the canadian cabin.

• This technique is unique and is distinguished by the positive specifics of Norwegian and Russian technology collected in it.
• Let's consider in more detail the most important nuances and features of this method.
• The Canadian log house differs in its features and individual specifics, which are important to study more carefully.

1 The cost is quite high due to the fact that the process is very laborious. However, the expense pays off with positive differences compared to manual felling methods.

2 In the technology of Canadian felling, several variants of grooves are used: traditional semicircular and m-shaped. The main distinctive feature Canadian cup - the presence of side obstructions. To accurately cut through all shapes, specialized equipment is required. In the process of marking, a compass of a unique design is used. Carpenters use axes for finishing grooves and bowls. Due to the high complexity of the Canadian bowl, the most important equipment and tools are the high professionalism of the staff and their experience. Without this, Canadian felling is impossible. Let us note without false modesty that we are proud of our masters - they have no equal in this laborious business!

3 The finished Canadian felling can be quickly distinguished from the others, outwardly it was created as follows: a groove with grooves is cut from above the wood, and a "fat tail" is made from below - a thorn. Because of such complex design the finished log house is not completely blown out. After the shrinkage process, it wedges on its own.

Alternating stages of Canadian felling

If you do not take into account the nuances of wood harvesting and drying, then it is quite possible to divide all the fundamental actions into the stages of construction of structures.

1 Having our own base, which is equipped with modern equipment, we select all the necessary structural details. We divide them into suitable and not. When dividing, we take into account important factors: the size of the logs, the technical condition after passing through the drying. If defects are detected, the wood is recycled. Auxiliary lumber is made from wood that has received obvious flaws.
At the houses of the Canadian felling we choose exceptionally smooth wood, which has an impeccable quality and the following dimensions: length from 6 to 12 meters, and diameter from 280 to 500 mm and more.
After this stage, our specialists perform primary processing - they remove the bark. A special tool, which is used to remove the bark (scraper), allows you to clean the surface as efficiently as possible and not damage the protective layer: "sapwood".
Another effective method processing, which is used by our specialists - "hydrocork". In this case, the bark is removed under the influence high pressure water.

2 The Canadian felling house is delivered to the customer's site in the form of a carefully packed structure. Delivery is carried out using special vehicles.

4 According to the markings created on the logs, the process of assembling the log house begins. During assembly, the Canadian bowls are sealed, which is guaranteed to exclude blowing, and also protects the frame from moisture and decay. An accurate calculation is made for the percentage of shrinkage of the structure.

5 During the installation of a log house, its antiseptic treatment is carried out. In this case, professional means are used that are guaranteed to help exclude any appearance of a variety of fungi and insects.

The costs of this work vary in Moscow, but our company offers reasonable prices for such a high quality housing.

Benefits of Canadian felling

Accordingly, the construction process is quite laborious and complex, but due to the mass of advantages it is worth it.

• Excellent thermal insulation, thanks to the extraordinary shape of the groove, a perfect connection of the logs is achieved.
• During processing, completely all upper layer persists, which favorably affects the main factors: freezing, cracking, twisting - all parameters increase. The room has its own microclimate.
• The high quality and natural beauty of the textures makes the home truly unique. Such a house does not require finishing, which significantly reduces overall costs.
• It is worth considering the fact that the quality of an erected house in 90% percent depends on the experience of specialists.

Considering this, we offer professional services of our company "Vityaz-Stroy". Our employees are highly qualified craftsmen who are guaranteed to build a house from the log of your dreams!

Cutting technologies originated and developed in different countries almost simultaneously. There were many similarities and differences in them. The craftsmen studied the experience of their foreign colleagues, adopted the best - this is how the Canadian felling technology appeared, combining the best features of the Norwegian and Russian felling. Many log houses today are built using this technology. Let's take a closer look at her.

Canadian felling is done manually. This is a laborious process, so it cannot be called cheap. But on the other hand, the owner of the log house receives many advantages that fully pay off all the costs.

Distinctive features of technology

Like other types of felling, the Canadian one has its own characteristic features. The main feature- a groove of a special shape, with a hidden thorn (fat tail), a bowl and an outer groove. For a clear match of the elements of each log, it is necessary to cut a groove very accurately. The master should not only have experience, but also a special set of professional tools - a special compass for marking and an electric saw, with which the wood is selected.

Manual felling requires professionalism from the builder, impeccable knowledge of technology and many years of practice. Such craftsmen work in the construction company SPK "Russkaya Izba". How we cut logs according to the Canadian method: a groove with runners is cut in the upper part of the log. A thorn is carefully cut on the bottom of the log. During the shrinkage of such a structure, a kind of "locks" self-wedge, and the structure is very strong, without cracks and gaps. Let's take a closer look at all the stages of construction of Canadian log cabins.

Read the same, oh Canadian technology

Sequence of work

The first stage of any construction is material procurement. We will not dwell on it, because our other materials are devoted to the preparation and drying of logs. Let's start with the stage of selection of logs and their processing.

Before building a house using Canadian technology, you need to remember that the slightest violation of technology nullifies all the advantages of such log cabins. Therefore, do not take the risk of contacting an unverified company. The masters guarantee you high quality at a reasonable price.

Canadian felling prices

Probably, many people dreamed of their small country house, erected from a wooden frame. These huts will look great both on their own and will be a great addition. landscape design... In addition, log buildings have excellent thermal insulation. It is possible to build such a house using several technologies, among which the Canadian cabin is the most popular. And this is not surprising, because winters in Canada are very cold and snowy, so Canadians certainly know a lot about building warm and cozy houses.

general information

Canadian felling, the technology of which will be described later in the article, is distinguished by its quality and has practically no drawbacks. It was invented about 50 years ago and during this time has become widespread throughout the world. This is due to the fact that the technology is completely based on manual labor and does not require the use of specialized equipment, so the cost of log houses is relatively low. However, in order for the house to turn out to be of high quality, warm and durable, it is necessary to have certain skills and knowledge, because when installing logs, every millimeter is important.

Choice of materials

Before you figure out on what principle the houses of the Canadian cabin are being built, you need to talk about the choice of materials. This is very important as the logs must meet certain standards. Their diameter at the top of the trunk must be at least 30 centimeters. This is due to the fact that their thickness after shrinkage and shrinkage of the structure will decrease. In addition, than larger diameter logs, the better the building will keep warm. However, such material is more expensive. Therefore, when choosing building material you should take into account your financial capabilities.

As for the length, the Canadian wheelhouse, the photo of which looks just amazing, involves the use of logs with a length of 14 meters. It is allowed to erect houses from a log house of greater length, however, in this case, the joining of the logs should be carried out with screw ties, and the joints must be closed with a transverse wall without fail.

A few words about wood species

The best material for houses built using Canadian technology is coniferous trees, which are highly resistant to moisture and have a high resin content. Such houses will not be afraid of any climatic conditions. In addition, structures made of these types of wood will serve for very long years.

In our country, the following types of trees are used for the construction of buildings using the Canadian felling technology:

• Pine is different high density and has a great resinous content, so houses made of this tree will last quite a long time, even if they are not revetted with anything.
• Larch, in terms of its density and the amount of resin content, surpasses even pine, so it is not only not afraid of moisture, but also does not rot.
• Cedar is prized for its antiseptic properties.

These types of wood are considered traditional for Canadian cut houses, so they are best used.

Construction technology

Canadian felling houses, the designs of which can be very diverse, is an ideal option for the construction of buildings from round logs in regions with heavy climatic conditions and very frosty winters. Logs and insulation are laid in such a way that the structure does not require facing, retains heat well and eliminates the presence of drafts.

The logs are joined together according to the thorn-groove principle. The spike is directed downward, which results in a higher thermal insulation. The groove is cut in the same shape as the tenon. Due to the identical shape of the spike and groove, the logs are firmly fixed to each other, and after the wood shrinks and the building shrinks, no gaps form between them. To prevent the penetration of cold air and moisture in the joints of the logs, a heater is placed in the cup.

When cutting a cup, a Canadian felling of log cabins involves cutting the logs at an angle of 45 degrees. In this case, the tilt radius may slightly increase or decrease depending on the thickness of the logs. To achieve maximum adherence of the logs to each other, after shrinkage, a small gap, approximately 3 centimeters thick, is hollowed out in the cup.

The size of the seating part of the stud depends on the width of the seating gap. Its minimum width is 9 centimeters. However, when cutting it out, you need to try to ensure that it coincides in its shape with the groove.

These rules are the basis for the Canadian felling. A project built using this technology will stand for several decades and will perfectly retain heat without replacing the insulation material.

Canadian and Russian wheelhouse: what are the differences

The Russian technology for the construction of log houses differs from the Canadian one in that in it the shape of the nest has the same shape as the log, while in the Canadian felling the bowl is trapezoidal. Thus, when joining the logs using Russian technology, gaps will form between them, which will have to be repaired, and this takes a lot of time.

However, the owner of a house built using the Russian felling technology will face the main problem in about the third year of operation of the building after it settles down. Quite large gaps will appear between the logs, which will have to be caulked. Canadian felling is devoid of this disadvantage, so the house will remain warm and protected from drafts for a long period of time.

The second significant difference lies in the ease of construction. Russian felling requires quite a lot of time and physical costs, since it involves multi-stage procurement and processing of materials, as well as an overly complex technology for laying logs. Canadian technology is simpler because there is nothing superfluous in it.

Benefits of Canadian felling

1. The processing of materials and the construction of the building are carried out entirely by hand, so the quality of the house can be controlled at all stages of construction.
2. Excellent thermal insulation. Thanks to the special technology of fastening the logs and the absence of gaps between them, heat loss is minimized.
3. Canadian felling allows the use of unbarked logs, which will provide better thermal insulation and additional protection from external factors and pests.
4. After laying the logs and completing the construction of the house, the aesthetic appearance of the tree is preserved, thanks to which the buildings look very beautiful even without cladding.
5. The technology is very simple, so people who do not have a construction education and similar work experience can master it.

In addition to all of the above, this construction technology is universal, therefore, it allows you to implement any projects.

If you have no experience in construction and did not study to be a carpenter, then when working with logs and creating a castle, it is recommended to use a saw and a chisel. First, notches are made on the log, after which everything unnecessary is simply hollowed out. To ensure that all the locks are of high quality, and the joints are reliable, it is recommended that you make a template in advance, according to which you will do all the work.

Conclusion

The Canadian felling is one of the best building technologies with which you can build a reliable, warm, cozy and durable log home. At the same time, during construction, you can independently control all processes, which will allow you to carefully work out everything to the smallest detail and create your dream home. During work, the most important thing is to adhere to certain instructions and observe safety precautions.

Log housescan be built using different technologies. Which one to use depends on many factors:

• functional purpose of the building;
• its total area;
• the presence of a certain type of building material;
• topography and climatic conditions;

Cutting methods "with the remainder" and "without the remainder"

When a felling is performed by the "with the remainder" method, or by cutting "into a bowl", a recess is cut in the logs, and the next log is laid in it. With this, the logs protrude beyond the boundaries of the walls for a certain distance (25 cm on average). Thus, the consumption of material increases at the rate of 50 cm for each log in the log house. Such costs are compensated by good protection of the corners of the log house from wind and rain. It is believed that such a log house is superior to other construction technologies in terms of stability. If the logs are processed accurately and with high quality, the building looks attractive and even decorative, moreover, it does not require either external or interior decoration walls. This felling method has many varieties:

• Russian cup,
• canadian cup,
• Norwegian cup
• German cup and others.

Today, the most common and technologically advanced methods are "Norwegian castle" and "Canadian cup".

Of the multitude known methods construction of classic log houses, there are two technologies for felling log cabins, allowing you to avoid cracks when the house shrinks and to do without its constant caulking.

Canadian cup

Canadian cabin of the house "Canadian Cup" there is undeniable advantages before other methods of making log joints. When cutting by the Canadian method, the log in the bowl and in the horizontal groove is adjusted especially accurately, with such a connection there are no gaps at all. But this is not the most important thing. Gaps are not formed even after the shrinkage of the log house, which is explained by technological features connecting logs. The Russian "cup" requires after performing periodic caulking due to the formation of cracks during shrinkage.

The Canadian cup is trapezoidal. Due to the trapezoidal shape, the bowl does not form cracks during shrinkage, since the upper log is pressed against the lower one during shrinkage, evenly settles and wedges in the trapezoidal cup. Thus, the geometry of the entire structure is preserved, the logs do not form cracks and do not twist.

Norwegian castle

Norwegian cabin "Norwegian castle" executed from a gun carriage. Such a log is made with a special profile: projections are made along the entire length of the log from one or both sides. For the carriage, only a thick log with a diameter of at least 270 mm is used. Thickness of trimmed logs according to Norwegian standards for outer walls It should not be less than 200 mm. In such a house, specific triangular shaped beads are visible in the corner joints, and the inter-crown heat-insulating materials are not at all noticeable, since they are located in the longitudinal grooves.

When the frame shrinks, the corner joints of the carriage are wedge-to-wedge, forming a very strong connection due to their own weight. This connection excludes deformation of the carriage. The wood dries, but no gaps arise, so the caulking of the walls may not be carried out.

The logs retain their height, so there is no need to increase the number of crowns when shrinking. Since some of the wood has been cut from the log, the dimensions of the interior space of the house increase.

The carriage can be used independently for the entire frame, or it can be combined with a rough round log.

The external attractiveness of the material allows you to do without external and internal finishing.

For log cabins built using Norwegian technology, pine wood is used, or less often other conifers. Such wood is the densest and most resinous, therefore it is less prone to rotting.

The durability of a log house

Log houses are particularly durable.

Chopped wooden huts, built in the 17th century with only one ax, have survived to this day. They do not look very modern, of course, but they are in good condition and suitable for living.

A wooden house has been in Sweden for 776 years. In the Swedish city of Mura, an old farm has been preserved, consisting of sixty wooden old houses. They have been preserved almost perfectly, it is quite possible to live in them.

The Canadian felling allows you to build durable and energy efficient houses and saunas from logs of different diameters. Thanks to the internal thorn in the bowl, the lock self-wedges, the walls are sealed, the joints do not diverge in the corners. Such log houses do not need to be caulked again! Carpenters from "ROYAL CEDAR" have been building log cabins using Canadian technology since 2002.

The history of the emergence of the Canadian felling

In the middle of the 18th century, Russian settlers brought this technology to Canada. The local population (Indians and Eskimos) did not know this method of building wooden houses.

In Russia, at the same time, architects preferred faster and less labor-intensive felling methods. Arriving in Canada, Russian craftsmen were forced to adapt the Russian wheelhouse to local conditions, sacrifice speed and simplicity, preferring reliability and thermal efficiency.

Now Canadian log houses are popular not only in North America and Canada, but also in other countries, including Russia.

Advantages

Building houses and baths with the "ROYAL CEDAR" is profitable! Only we:

• We carefully select building materials. We have a production site and logging plots. We do not buy wood, we cut it ourselves in the Siberian taiga! Each tree is inspected by a master with twenty years of experience and checked by an ultrasonic flaw detector. For construction, workpieces with good tapering properties, density and resin content are used. Our logs have no visible or hidden defects. Unsuitable specimens are rejected and used for the production of lumber.
• We develop detailed projects. The draft part is a sectional frame, a layout with an explication of the premises and a foundation plan. All the documents necessary for production are contained in the constructive section: cutting cards for all types of lumber, laying diagrams of crowns and wall sweeps. All project documents are created automatically, which eliminates errors. Our log houses are cut in strict accordance with the design development, and each position in the estimate can be substantiated with documents.
• We employ the best carpenters and finishers. We build turnkey houses and saunas. We do not involve subcontractors in our work, we carry out all design, construction and finishing works ourselves. The best Siberian carpenters and general-purpose finishers work in our staff, so we are confident in the result. All work is our guarantee!
• We offer prices from the manufacturer. The projects from "KOROLEVSKIY KEDR" contain documents that allow you to save money: cutting cards wall material and specifications of all lumber. We are manufacturers and do not work with intermediaries. Our Customers pay only for the material and work of our craftsmen. Remuneration for intermediaries and resellers is not included in the construction budget.

Canadian felling: technology features

• Canadian cabin combines the characteristic features of the Russian and Norwegian styles. Logs are suitable for construction large diameter, which are carefully adjusted to each other when assembling the structure.
• Carpenters make a special "lock": in the lower rim, a thorn is cut in a wedge-shaped bowl, and in the upper rim, a bowl in the form of a trapezoid is cut. Under the weight of the logs during shrinkage, the fastening is tightly jammed, due to which a complete tightness of the "lock" is achieved.
• Full coincidence of bowls in shape and self-wedging of the "lock" minimize the risk of joints opening over time. Moisture does not penetrate inside the corner. The insulation located in the grooves retains its natural properties for a long time.
• With Canadian technology, a double-sided paddle is made logs at an angle of 45 degrees. The length of the paddle is equal to twice the diameter of the log.
• For Canadian log cabins, logs processed with a scraper are used. This tool allows you to very carefully debark the workpiece, leaving the sapwood intact. Such logs look original, and the log cabins from them serve for a long time.
• The grooves are made with adze, the wood is chipped along the grain. This clogs the pores and resin channels. This "conservation" increases the life of the wood.
• For Canadian felling, it is recommended to use logs with a diameter of 400 mm or more. We build from cedar, pine and larch up to 700 mm in diameter.

Features of Canadian log cabins

• Tightness. A log house with round bowls after shrinkage needs caulking or wall treatment with acrylic sealant using the "Warm seam" technology. The appearance of cracks is associated with a decrease in the linear dimensions of the log due to shrinkage. There is no such problem in the Canadian wheelhouse: the inclined edges of the lock and self-wedging under the weight of the crowns and the roofing system preserve the tightness of the joints. In such a frame, no cracks appear, the cut remains airtight.
• The walls look monolithic. There are no gaps between the crowns, this remains throughout the entire life of the log house. The insulation remains inside the log, it is invisible and reliably protected from environmental influences.
• Nice appearance. Curves on a large diameter log look original. In the construction of elite log cabins, logs with expressive butts are used. The ends are made "wedge-like" or "run-apart". French and straight edge trims are also available. Our carpenters own the author's method of drawing the butt parts. Large diameter logs are widely used, processed in "wild" style or with partial debarking. The massive chopped trusses that adorn the entrance group look original.

Diamond bowl or Diamond paddle

• Construction of houses in a diamond bowl requires high skill from carpenters, because this is a very complex technology. The difference from the usual Canadian technique consists in the number of laps - they are performed not on one side of the crown, but on two:
• In intersections intersects a large number of faces, which looks like a diamond. This is where the name of this method comes from, with which you can emphasize the natural shape of the butts and the beauty of the woody texture.
• The pinnacle of cutters' craftsmanship tightly fitted (up to a millimeter) corner joints of the crowns are considered.
• Benefits of a diamond bowl the same as in the usual Canadian one: complete tightness and no cracks after the shrinkage of the log house.
• The only drawbackdiamond pad is the reduction in the width of the thermal groove. It is for this reason that it is advisable to choose this type of felling when a wooden house is being erected from a log with a diameter of more than 460 mm. In large log cabins, a diamond wedge looks especially exquisite!

House kit composition

• Wall logs;
• Lumber natural moisture for:
• overlappings;
• rafter system;
• lathing;
• floor or ceiling;
• Mezhventsovy insulation "Klimalan";
• Dry birch head;
• Roofing material;
• Protective compounds "Remmers";
• Shrinkage jacks;
• Hardware.

Construction time

The construction time depends on the complexity of the project, the diameter of the logs and the workload of the production site.
