Despite the large number of emerging new materials, wooden houses remain in the spotlight. Many people dream of living in such a house, because they are inherent in a special flavor and some sense of additional space.
Technologies for building wooden houses do not stand still, newer, more advanced ones appear, but the main thing that remains unchanged is the most environmentally friendly type of housing.
How is the beam
This is lumber, which will be obtained as a result of sawing whole logs on one or more sides. The result is a wooden block with the same cross section along the entire length, which greatly simplifies the process of erecting and decorating a house. Thanks to this treatment, the sides have a large area of contact with each other, therefore, the walls of the beam can be made thinner than when building a house from logs.
The finished beam must be coated with a special composition, which gives it fire resistance and does not allow the appearance of various types of fungi and foci of decay. Depending on the manufacturing technology, the beam is divided:
- on unshaped, section from 150 to 220 mm. The easiest to assemble and inexpensive;
- profiled. It has special seats in the form of grooves that provide maximum fit;
- glued. For its production, different species of wood are used. A beam is obtained by cutting logs on boards. They are dried and treated with an antiseptic, and then glued. The result is high-quality building material with a low percentage of shrinkage.
Optimal cross section
The decisive criteria for choosing the thickness of the beam during the construction of the house is its location and purpose. And if the buildings for summer living do not require any special attention, then the houses in which the person is going to be constantly must keep heat well in the cold season.
There are certain building codes that indicate wall thickness indicators depending on the temperature regime in a particular region of the country. It is calculated from a strictly defined formula.
So in the central region, in order to meet the obtained indicator, it is necessary to use a bar with a cross section of 500 mm for the construction of a house. Since such a material does not exist, the best option is a 200 mm thick timber with the addition of a certain layer of thermal insulation.
It is known that 50 mm of insulation replaces 150 mm of wood. That is, the thickness of such a layer with a beam section of 200 mm should be 100 mm. Mineral wool is usually used as insulation. It provides a dry wall with high humidity.
In such a warm wooden house, it is comfortable to work and relax, since air humidity is naturally regulated in them, and the wooden walls nourish its inhabitants with their energy and strength. Therefore, the beam can be called one of the best building materials.
