What to choose: dry profiled beam or plain

Despite the popularity of stone housesMany developers prefer to build houses out of wood. The market offers a variety of wall materials for the construction of a wooden house. We already told readers FORUMHOUSE about features houses from glued beams. Now we will try to determine that it is preferable: dry lumber or natural humidity.

Seemingly obvious answer, everybody wants to save money and therefore it is better to choose a normal, or as it is called, "hairy". But the building does not tolerate fuss. Before making a final choice, it is necessary to understand the key characteristics of these materials and to understand what they have advantages and disadvantages.

Timber natural moisture - what is it

Neutral beam obtained by treating whole logs. The finished product has a rectangular or square cross section. ease of production affects its low price and popularity.

 However, it does have some disadvantages.

It planed natural moisture content of wood. In accordance with GOST 8242-88 dry timber - a tree whose moisture content does not exceed 18-20%. Wood with a moisture content greater than 20% - timber with a natural moisture.

This material begins to be deformed during drying. It can spin the "helicopter" may cause cracks. HouseBuilt out of it sits a long time.

Shrinkage walls is 5%. Do furnish a house built of such material, it is possible only after it settles 6-12 months.

Purchased material must be stored in stacks, providing free circulation of air between the bars, which are laid board 2-3 cm in thickness therebetween.

It is also necessary to provide protection from rain and direct sunlight.

Some developers try to "get around" a number of negative characteristics of the material.

- I've heard that if you take a normal board, with a section of 150x200 mm, and put him to the wide side of the horizon, it would be less twist and tear.

Indeed, it is less crack, but if you compare house built of timber 200x200 mm and a house made of timber 150x200 mm, then the same height buildings cottage built smaller cross-section of a tree, give greater shrinkage (as have laid greater number series).

Timber natural moisture, while its improper storage may start to rot. Its geometry is far from ideal, so a house built from this material requires konopatka. If you do not (and will have to caulk the house more than once), the walls begin to blow the wind. In winter, the owners of the cottage are actually heat the street.

Before starting the construction of a log house is necessary to determine the purpose of this building: cottage or permanent residence.

- In my opinion, if the house is built for permanent residence, you can take 150x150 mm, and then warm it.

If additional insulation is not provided, then the home for permanent residence (depending on the region of residence) is taken the material of at least 200x200 mm. If less, then the house will be cold.

The walls of a house built from conventional timber, due to unevenness and roughness require additional finishing. This leads to additional costs.

Pros:

• Low price, especially in the winter time;
• publicly available;
• Easy to assemble at home - enough carpentry skills.

Minuses:

• The need for repeated konopatki walls leads to an increase in construction estimates;
• The need for additional finishing;
• At drying may strongly change their geometry, leading to deformation of the walls.

Dryshaped beam

This material has a complex cross-sectional shape. Faces his smooth and well rounded. The upper and lower part (when viewed from the end, the so-called working side), a sample of "tongue and groove" or "comb".

Thanks to this profile provides greater sealing compound, decreases the degree of blowing walls. In most cases, the house, built of profiled material requires no additional finishing. Simply paint the walls to emphasize the texture of wood.

When the compound "tongue and groove" between the elements laid mezhventsovogo heater. Even if a little drying timber will lead, the connection is "tongue and groove" will prevent the blowing off of the walls.

Features Connection "comb" lies in the fact that the teeth exactly match each other. Therefore there is no need to use mezhventsovogo insulation. When building a house used bad-dried material, when dry it can change its geometry, which will greatly reduce the reliability of such a connection.

The main advantage of the dry shaped timber is that prior to processing on the machine it is dried and cull defective products, which changed its geometry or started rot.

Thus, to build a house there is a higher quality material.

Drying takes place either in a special drying chamber, either naturally, when the material is placed in a ventilated stack and kept under a canopy for protection against rain. When the drying chamber it dries in chambers equipped with heaters. By automating the process, an optimal drying mode is supported in the chamber. It depends on the timber size, type of wood and its entry-level humidity.

Therefore, the dry shaped beam deforms less than the natural moisture. This material is better retains its geometrical dimensions, fewer cracks and less prone to growth of molds.

What to choose: profiled bar of natural humidity or dry

There is also a profiled bar of natural moisture. It occupies an intermediate position between normal and well dried profiled. The main difference from the usual (except Profile) that prior to processing on the machine it is dried naturally until its moisture content reaches 22%. Also discarded material with apparent defects: cracks, "screw", etc.

Humidity dry profiled bar is in the range of from 12 to 20%. Shrinkage walls composed thereof is 2-3%.

All the advantages of this material may be reduced to "no" when it is improper transportation and storage. Dry timber can quickly absorb moisture from the atmosphere. Measure the moisture level can be hygrometer for wood.

- In my opinion, the main advantage of shaped timber is its high color quality. If a house out of it is going to an experienced team, the structure does not require additional finishing. Yes, and the house looks more solid, more effective.

House near Moscow, assembled from this material.

Cons dry profiled beam:

• High price;
• The material loses all its dignity in violation of the conditions of storage. This may lead to cracking and formation of cracks;
• The assembly should be carried out at home professional brigade, which has experience of working with such material.

Leskos (Member FORUMHOUSE):

- If profiled bars appear gap, it, unlike a simple, does, of course, do not caulk. I also believe that if we take a simple, self-dry it and prostrogat, outwardly it will look better than profiled, but the price will be much less.
