Calculation of the number of logs rounded

Information on the purpose of the calculator

Online calculator of rounded logs is designed to calculate the number and volume of logs for a house, bathhouse and other buildings, taking into account pediments and internal partitions. Additionally, calculations are made of the useful area of the room, the number of crowns, the diameter and number of wooden nails, as well as shrinkage and load on the foundation.

From time immemorial, log houses have been famous for their quality, high heat capacity and environmental cleanliness. With the growth of individual construction, with the advent of aerated concrete, foam and other modern materials, interest in wood has not decreased at all. Even today, in the age of innovation and new technologies, many land owners continue to build wooden cottages and cottages, preferring rounded logs.

What is a rounded log?

The material for rounded logs is usually coniferous wood. According to the ratio of cost and consumer qualities, pine is considered the best. When digitizing, the top layer (sapwood) is cut off from it and the core remains impregnated with resin and has a characteristic coniferous aroma.

When the sapwood is removed, the number of cracks on the log decreases, which significantly increases the thermal insulation of the material. After rolling on end-cutting machines, the wood is impregnated with special mixtures that provide protection from the external environment. Despite the multi-stage processing, its magnificent pattern remains on the surface of the tree, which gives the appearance of the structure variety and elegance.

Advantages of buildings made of rounded logs

Rounded logs are a good alternative to a sanded log or sawn timber. They are not only not inferior to these types of building materials in quality and durability, but also have a number of undeniable advantages:

• Due to the smooth and smooth surface of the log, the new house does not require decorative finishing.


• The logs have neat grooves made on special machines, so that during construction they can be tightly joined at the corners of the structure.


• The installation and construction time of the house can be significantly accelerated by calculating and pre-preparing a complete building designer.

In the hands of a skilled craftsman, wood seems to find a soul and pleases the owners of houses with a pleasant shine, aroma and unique pattern. Cottages made of rounded logs are able to provide comfort, it is easier to breathe in them compared to stone boxes of urban apartments, and the ability of wood to accumulate heat in summer and keep in winter allows you to build such buildings in areas with any type of climate.

The following is a complete list of calculations performed with a brief description of each item.

General information on the results of calculations

• Total log volume
- The estimated amount of lumber in cubic meters.
• Perimeter of the building
- The total length of all walls, taking into account the projection of the corners (paws).
• Usable area of the room
- The area of the room, taking into account the deduction of the output and the thickness of the log.
• Total area of exterior walls
- The area of the outside of the walls. Corresponds to the area of the necessary insulation, if such is provided by the project.
• Total weight
- The weight of the log without insulation.
• Number of rows
- The number of rows of logs in the wall. Depends on the height of the walls and the size of the material used.
• The number of rolled insulation for all rows
- Equal to the total length of all logs.
• Diameter and number of wooden nails in 1.5 meter increments
- This calculation is suitable only for lightly loaded log buildings. For responsible buildings, the calculation of wooden nails must be carried out by specialists in your region.
• The amount of protective liquid solution from 2 sides
- The estimated amount of protective liquid solution, coated with the outer and inner surfaces of all walls.
• Approximate shrinkage (7%) of a rounded log
- Approximate shrinkage of walls made of rounded logs after 1 year, with an initial humidity of 20%.
• Load on the foundation from the walls
- Load without taking into account the weight of the roof and ceilings, with support on the entire surface of the lower crown. This parameter is necessary to select the strength characteristics of the foundation.
