How to use unplaned timber
Over the past decade there has been a clear trend in the approach to the choice of building materials. The tendency is in the preference of highly efficient modern products with unique heat-conducting and sound-proofing properties. Also the developer, especially private, is attentive to the environmental friendliness of products for the home.
Against this background, wooden construction, combining almost all the required qualities, does not lose its position, but has a constant development and growth. Especially since, for example, a bath from an unplaned bar is a very affordable construction object for a summer cottage. And the work itself can be done independently with even minimal experience.

Use of unplaned timber in construction

For the construction of various buildings used several types of building materials made of wood. In addition to traditional or rounded logs, timber with a different degree of processing and size has become very popular. But the most democratic and affordable is unplaned or sawn timber.

Production, main features and dimensions
Nonstrict timber is a log sawn from all sides with different cross-sectional dimensions in the square or rectangular shape in section without any additional processing. It is best to use timber from the winter harvesting for construction - outwardly it looks lighter and with a less rough surface.
Industry bars are available in lengths from 2 to 6 meters, but the standard length is 2, 3 and 4 meters. They should be made of dry or dried wood, with a moisture content of about 10%. But, given that prolonged drying in convection ovens or microwave is often unprofitable for this type of timber, most often commercially available material with a so-called natural moisture level.
The quality of such a product does not suffer, but requires compliance with certain conditions, the most important of which is that the building should be able to shrink for about a year, and perform all finishing work only after that.

The most common sizes are 150? 150 mm and 200? 150 mm, but can also be found with a different section. Thickness primarily affects the heat-conducting properties. For a bath device, for example, it is better to use products with a large cross section, and for a house in the country, in order to save, we can even allow 100? 100 mm, first of all, because it will still need to be warmed and refined. Although the optimal size for building a house is 150? 150 mm.
It is necessary to take into account the factor that a bar of smaller thickness increases the number of crowns and, accordingly, the number of dressings, which will require an increase in the cost of insulation. Therefore, in each case, it is necessary to take into account the characteristics of the future structure and all related and additional factors.
Advantages and disadvantages of buildings from unplaned timber

Unstressed timber as a building material has undeniable advantages of use and positive characteristics:
- availability:
- low cost;
- You can buy at almost any base or in the building supermarket;
- efficiency of delivery, as a rule, is always available and the product range, and a sufficient amount of material;
There are some disadvantages that can be leveled under certain conditions or events:
- timber subject to education:
- cracks;
- the gaps between the crowns;
Attractiveness of unplaned timber for private construction

This type of timber has become widespread in the country building, due to several factors:
- low price of the material;
- environmental friendliness;
- low costs for the construction itself, since it does not require the involvement of special construction equipment; for some types of work, such as roofing or lifting timber, there is enough small-scale mechanization;
- construction is not only possible but necessary to be carried out in stages, which is more important for many developers;
- the summer house, which is operated only in the summer, thanks to its excellent air exchange characteristics, tolerates the winter well. (See also the article House from a bar for two families: advantages)

Council Nonstrict timber is used not only for the erection of the building box, but also for the installation of roof rafters, a log for the floor;
Conducting protective measures: their meaning and types

Using a non-planed bar in construction, you should take care of its special treatment. This is necessary because it is made of natural material and has not only the advantages of natural origin, but also disadvantages.
Protect from the following factors:
- reproduction in wood of various microorganisms - antiseptic agents; (See also the article Processing of timber from rotting - the key to long-term operation of the building)
- for the purpose of counteraction and resistance before the fire - antipyrite;
- Treatment with varnishes or paints is used to protect the upper layer, as well as the destruction of the material and the whole structure due to the impact of adverse natural factors - rain, snow, and sometimes elevated groundwater levels.
First of all, it is necessary to protect the foundation from the impact of groundwater and properly build it. But the timber itself needs special protection.
It is possible to carry out work aimed at protecting the timber before construction or immediately after the construction of the box of a country house, bath or other structure. Sometimes it makes sense to use different formulations, but many choose the combined, guaranteeing protection against two or more problems.
Such compositions are made by different manufacturers, differ in characteristics, price, but when using them to achieve the maximum effect, instructions for use should be strictly followed.
Council Choosing protective equipment, it should be remembered that universal remedies with a wide spectrum of action, as a rule, turn out to be less effective than specialized ones for one particular problem.
How to heat the house
If you plan to use the house in the winter, you should take care of the type of heating. If the area is small, then the most optimal would be to use convectors or electric boilers. And to create a comfortable environment - you can make a fireplace or lay down a semblance of a Russian stove.
Conclusion
Wood for the manufacture of timber can be used very different - and coniferous, and deciduous, but mainly on the market presented products made of pine or spruce. Grade and species classification of timber is governed by GOST 8486-86. GOST describes four varieties, while the most widespread are products of the I-th grade.
