Wooden bar 200х200 - alternative to log for log

Now it has become fashionable to acquire a wooden cottage or a bath, and many and their main dwelling want to make this the most environmentally friendly material. After all, a tree house is in no way inferior to stone counterparts in the basic parameters required for a dwelling, but only wooden buildings have the ability to "breathe" with all the walls. This property helps to maintain in the home a favorable microclimate for the health of people living in a wooden house.

Affordable construction

The return to the construction of wooden houses has been considerably facilitated by the use of a wooden bar with a large cross-section for this purpose (bar 200 by 200 by 100 by 200). The technology of construction of buildings from this material is available even to beginners, whereas the prerogative of exclusively professionals is the construction of a log log house.

In view of the foregoing, lumber is in special demand in the range of:

• Bars 200x200x6000 mm.
• With a section of 200x200x2000 mm.

Wide selection

After all, log houses made of 200x200 timber will simultaneously possess both an aesthetic look and excellent thermal performance due to the large thickness of the timber.

This lumber is presented in a wide range:

1. Dry.
2. With natural moisture.
3. Glued.

1. Whole.

• Planed.
• Profiled

Note! Each type is more costly, the most expensive option is considered glued material. We will talk more about pricing in the next section.

The raw material for the manufacture of solid timber is round timber, for glued laminated timber - several boards of different thickness.

The bar can be made with the section:

• Square.
• Rectangular.
• Complicated geometry (profiled), with grooves and ridges for better fastening.

Most often for the construction of the walls of wooden buildings using a square timber, less rectangular. However, the profiled counterpart significantly pressed its counterparts in the field of low-rise construction. This is due to the convenience of its use even by amateurs in construction.

Cost of

The price of the finished product depends on the source of raw materials.

For the production of building material, in principle, it is possible to use wood of various tree species, but softwood timber is in particular demand:

• Ale.
• Pine.

This is due to a fairly affordable price, with the ability to perfectly cope with the task.

In addition to the type of wood from which the timber is made, the final cost of the material also depends on:

• Humidity
• Manufacturing technology.
• The volume of purchases.

The most expensive of such lumber is glued laminated timber 200 by 200.

Further, according to the principle of reducing the price in order:

• Dry profiled timber.
• Dry planed timber.
• Profiled timber of natural moisture.
• Planed timber of natural moisture.

Cost of единицы бруса

Calculate the cost of timber, usually at 1 cubic meter. Knowing the cost of one cubic meter of lumber, you can easily calculate the cost of one product (with a specific section and length). Take, for example, the bar 6000 to 200 to 200.

Instructions for calculating the cost of a unit of material:

• We calculate the volume of one product 6000x200x200 (for convenience, we conduct calculations in meters) - 6 x 0.2 x 0.2 = 0.24 m3.
• We find out how many such bars in a cubic meter are 1 / 0.24 = 4.2 pcs.
• We divide the cost of one meter of cubic lumber with a certain humidity by the number of pieces in a cube. In our case, 4.2.

We give the average cost per cubic meter of various types of building materials 200x200x6000 mm from softwood:

1. For products with natural moisture.

• Profiled - from 8000 rubles.
• Planed - from 5500 rub.

1. For timber from dry raw materials.

• Glued - 18,000 rubles.
• Profiled - 10,000 rubles.
• Planed - 8000 rubles.

Note! All prices are based on an average. In your area, they may differ slightly - either up or down.

To summarize, one dry planed timber 200x200x6000 will be - 8000 / 4.2 = 1904.8 rubles.

Attention! Carefully check when buying the dimensions of the bar. With a slight deviation in the cross section, say up to 190x190 mm and the purchase of several dozen cubes of lumber, you can significantly lose in material terms.

Mass of one cubic meter of timber

With moisture and dryness, everything is clear from the name, but not everyone has a moisture meter - a device for determining the degree of moisture in wood. Do not despair, it is possible to determine the dryness of sawn timber for purchase by its weight.

That is why, you should ask how much one cubic meter weighs or piece of product, the selected bar. In addition to moisture, the wood of which it is made also affects the weight of the lumber.

For conifers, our “favorites” of pine and spruce, under similar weighing conditions, the weight figures are as follows:

• For a bar of raw materials of natural moisture weight of 1 m3 - 800 - 900 kg.
• For dry material - 450 - 470 kg.

Note! The mass of glued and planed (solid) logs, with similar linear parameters and humidity, is almost the same. But the weight of the profiled product varies depending on the profile configuration.

The weight of one product of appropriate humidity is easy to calculate, knowing the number of units per cubic meter of lumber.

The number of units of timber in one meter cubic

Since all calculations for wood, including the purchase, are carried out in cubic meters, you should learn how to recalculate the number of timber units per cubic meter.

It is easy to do by the simple formula N = 1 / (A x B x L), where:

• N - the required number of pieces.
• A, B - parameters of the beam section.
• L is the length of the beam.

The calculation for a 200x200 bar with various length indicators is as follows:

• Dimensions 200x200x2000 - 1 / (0.2 x 0.2 x 2) = 12.5 pcs.
• Dimensions 200x200x3000 - 1 / (0.2 x 0.2 x 3) = 8.34 pcs.
• When L = 4000 mm, respectively, N = 6.25 pcs. etc.

We calculate the weight of a bar 200x200x6000 from pine with natural humidity - (800/1) / (0.2 x 0.2 x 6) = 191.85 kg. According to this scheme, it is possible to calculate the mass of any timber with various sizes and degrees of humidity.

Selection and calculation of timber for construction

To begin any construction should be with the procurement of necessary building materials.

Here are some things to consider when drawing up a procurement plan for basic building material:

• The size of the building. Based on them, the length of the bar is selected 200x200. Well, when in the wall fit, at least a few units of material full length. But if you decided to build a house of 8 by 8 meters, the delivery of lumber of such length can not always be possible. As a rule, timber 20x20 cm is made of standard length of 6 meters. Other options for you to make to order.

Note! A timber is joined not by simply applying one product to another, but by sampling grooves and driving dowels.

• Purpose of construction. The country house can be built from a material with a section of 100x100, 150x150, but log houses from a bar 200x200 are suitable for permanent residence.
• Region of construction. What matters is where you are going to build. The thickness of the lumber for your home should provide warmth and comfort in the rooms. The low thermal conductivity of timber 200x200 makes this material the most appropriate for ensuring optimal living conditions, with an economical heating mode.

Note! A bath from a bar 200x200 will also be good, because along with low thermal conductivity, wooden material has good vapor permeability. For pine and spruce, this indicator is 0.32 Mg / (m * h * Pa), thermal conductivity along the fibers is 0.18 W / m * C.

It seems that private developers, who wished to build with their own hands from wood, probably found something interesting and useful for themselves in our article.

Conclusion

A section of 200 by 200 is not the only option proposed in the construction market, but is considered quite popular due to its qualities. After all, it is this material that allows to erect two-story houses and not spend money on calling construction equipment, all work is done by people and hand tools.
