Canadian felling, Russian bowl or Post and Beam - you choose!

Manual felling of logs in different styles from the company Bear log

Felling logging technologies - from Canadian felling to Post and Beam houses.

In wooden housing there are two main technologies for felling logs - cutting in a bowl, it is divided into Canadian and Russian logging, as well as frame-timber technology - the so-called Post and Bim, from the English words Post and Beam (pole and beam).

Thanks to the manual chopping the highest quality is achieved, which cannot be obtained by processing logs by other methods. It was during manual processing that the log ideally retains its qualities - warmth, durability, natural beauty and resistance to environmental influences. Hand-cutting technology affects not only the style and appearance, but also the thermal conductivity and manufacturability of chopped logs. The ability to use various materials for finishing and building a house. We will try to explain to you what the differences are.

Felling log in the bowl

Felling logs in the bowl the most common type of felling. The walls in this case consist of logs arranged horizontally. Bowls are cut at the junctions or intersections of the walls (over-cuttings) during logging in the log. The cutting technology can be used according to the Russian technology with a round bowl or the Canadian log house can be used, which is also divided into two types - the traditional Canadian or diamond bowl.

Felling log in Russian bowl

The most common type of felling in Russia

Felling of logs in the Russian bowl - has long been the most common type of cutting in Russia. In the overcut, all logs and bowls are round.

Disadvantages of felling technology in the Russian bowl.

In the process of drying the logs are reduced in size and in the places of the corner joint of the logs, gaps are formed, which are larger in size as the diameter of the log is thicker. For example, if you used logs with a diameter of 30 cm in your log house, then gaps around 7 mm can be formed. And if the log is on 40 cm, then the gaps can be up to 10 mm.

The advantages of felling logs in the Russian bowl.

This type of logging is not for nothing caught on in cold Russia. Typically, the width of the groove in the log (heat lock) is about half the diameter of the log.

Canadian log house felling

Canadian logging is the most logical technology in wooden housing construction using logs with a diameter of 36 cm and more.

The main advantage in the Canadian bowl during the cutting of the corner joint on the top of the log is making curtains that give the log in the place of the over-cut not round, but saddle-shaped. Due to this, the upper log in the process of shrinkage does not form a gap in the overlap, but slides down along the made barbs and prevents the appearance of gaps between the logs.

In the overcut in the log, the upper barbs are formed to improve shrinkage processes.

Advantages of felling technology in a Canadian bowl.

The processes of shrinkage of a wooden house for tenants are more inconspicuous.

Cons cutting log in a Canadian bowl.

During the formation of curtains, due to which in the Canadian bowl, the drying process decreases more favorably the width of the heat groove between the logs. When chopping a log in a Canadian 30 cm log bowl with a diameter of the groove width is about 10 cm, and from a 40 log cm, about 15 cm.

Cutting a log into a Canadian diamond bowl

Felling log in a diamond bowl

A wooden house or a bath felled in a Canadian diamond bowl is considered to be aerobatics. A chic appearance is achieved not only by the upper notches in the overcut, but also by the lower ones. Due to the repeated intersection of the faces (spikes) in the over-cut, this type of logging got its name - diamond.

The advantages of the technology for cutting log cabins into a Canadian diamond bowl.

The same as the traditional Canadian bowl - favorable processes for logging in the period of shrinkage of the log.

Disadvantages of felling logs in a Canadian diamond bowl.

The small width of the thermal groove. It may be even narrower than the house felled in a traditional Canadian bowl, as the log has barbs on the top and bottom of the log. We recommend building houses in a Canadian diamond bowl made of logs with a diameter of at least 46.

Felling log in a hybrid style.

Felling log hybrid style. Walls in the Canadian bowl, roof post and bimEverything is very simple and clear! Ground floor is chopped, attic floor Post and Beam, timbered rafters and angle of roof 33,5 degrees - Characteristic Canadian style!

Benefits of felling in the hybrid style

If you have a difficult (not double-pitched roof), then use chopped pediments is not possible. The truss system is rigidly fastened with crate, counter crate, roof covering will not allow gables located perpendicular to each other in the process of shrinkage to change the angle of the roof slope using natural sliding supports for rafters. On the gables between the logs, slots are necessarily formed equal to the size of the service logs.

Disadvantages of cutting felling in a hybrid style


Felling log on technology Post and Beam (Post and Beam)

Cedar house cutting using Post and Beam technology

The technology of post and Bim logging, when the frame - the base of the house consists of beams and pillars made of logs, allows you to use a variety of materials to fill the walls - horizontal logs without overburden, stone, glass. As a rule, framed walls with various types of cladding boards are made - log siding, shingles, imitation of timber or unedged boards. Also on the frame wall, you can easily lay tile or stick wallpaper. Timber frame houses allow using completely different finishing and construction materials in the design.

Advantages of felling Post and Beam

Frame-timber construction is very stable and practically does not shrink.

Disadvantages of logging felling by Post & Beam technology

The disadvantage of a frame-and-beam construction can be filling the walls with a chopped log. The height of the pillars and beams in Post & Beam houses remains unchanged over time, while the chopped walls are subject to shrinkage.
