Profiled dry timber and its application

Relatively recently, a serious competitor to the log and glued laminated timber came to the market - dry timber 150x150 or, in other words, “chamber drying” timber. Now many people who want to rebuild their country house or bath, are paying more and more attention to it.

That is why we will devote this article to such material. We plan to tell you about what parameters, advantages and disadvantages a dry bar has, how it is made and how you can build a house with your own hands.

Characteristics of the material and its production

First of all, consider the material production process.

It can be divided into the following main stages:

1. The raw materials received by the company (as a rule, it is a bar of natural moisture with a rectangular section) are sorted by size and type of wood. Defects are detected (blue, rot, etc.) and the rejected beams are returned to the supplier.

Note! At this stage, the entire timber from dead wood (dead, affected by pests, wood) is rejected. If you have such an opportunity, be sure to check the quality of the material before purchase.

1. Then calibration is performed, i.e. selected timber of certain sections. Cuts are made on selected beams in order to avoid cracking during drying;
2. Upon completion of the preparatory stages, the bar is placed in a special drying apparatus, where the material dries to the desired state in a soft mode for up to 3 weeks.

1. Upon completion of drying, the material is subjected to planing on a spindle machine, acquiring its final shape in the process.

1. If a typical house or a bath is built from a dry timber from a material, then a facing will be made and all the necessary fastenings for the project will be cut out;
2. Before sending the material to the site, it is packed in plastic transport bags.

Now you know how to make the chamber drying beam. Let's talk about the advantages that are at home from a dry bar.

The advantages of chamber drying beams

1. First of all, the material is environmentally friendly and does not cause complaints on this issue (unlike, for example, glued, because you do not know exactly what kind of glue a particular manufacturer uses).
2. The meager “drying” of not more than 3% serves as a guarantee that the structure does not “warp” and “twist”;
3. All warped beams are rejected at the end of drying, besides soft drying by itself prevents the occurrence of a large number of cracks;
4. If you are planning to order the house on a turnkey basis, then this material assumes the shortest possible time for putting the house into operation;
5. The material has such pleasant performance characteristics as:
6. low thermal conductivity;
7. high moisture resistance, with proper pretreatment;
8. does not need prokopachivanii upon completion of the "shrinkage";
9. nice looking surface does not require a mandatory finish;
10. As a result, we can say that the material is perfectly balanced in the ratio "price - quality".

Other distinctive features of a dry bar

In this paragraph, we consider the basic parameters of the material with specific numbers, as well as compare it on some items with the "competitors" - a bar of glued and natural moisture.

• sizes for all types of timber are standard: a six-meter beam with a cross section of 100 per 100, 50x50 or 200x200.
• humidity: 16-22%, for comparison: natural 25-85%, glued 8-22%.
• shrinkage period: from 2 to 5 months, compare with the year for the "freshly sawn" competitor;
• shrinkage percentage: 2-3%, natural 3-5%, glued 1-2%.
• insulation is better than glued, but worse than a solid log.
• strength depends on the type of wood used (most often use conifers);
• the appearance of the rebuilt walls after shrinkage is quite good: solid timber with a woody structure, cracking in no more than 5% of the area;
• the appearance of the ends of the building: as a rule, there are cracks, leaving under the decompressive cuts;
• resistance to harmful insects increased due to mechanical drying;
• ventilation is fully carried out, since the wood structure is intact, unlike glued laminated timber, the glue in which does not allow the house to be ventilated
• 100% natural material, which can not be said about glued laminated timber - depending on the quality of the adhesive, it is only 40-90% natural;
• the cost of the material is fully justified and amounts to 15 thousand rubles. per cubic meter, which is about twice cheaper than glued "fellow".

But, of course, no material is perfect, and there are some flaws.

Cons of dry timber

1. Unlike a log house, the whole structure of its growth rings is disrupted during the production of a timber. Because of this, it is necessary to take care of it more carefully: it must be soaked with antiseptic, in some places even tint;
2. Compared with the same log house, the house of dry beams stores heat worse, due to voiced in paragraph 1;
3. The massive timber inevitably dries out, which leads to the deformation of its seemingly ideal surface. But nevertheless there is a way out of such a situation: a unloading cut will reduce stress and will not allow a large number of cracks to appear.
4. Since the house is made of wood, it will be easy prey for decay and insects. The salvation from the situation will be the periodic impregnation of the surface with antiseptics.
5. Due to its “woodenness” the house is subject to fires, therefore it should be treated with special protective compounds.

How much weighs the material that interests us

Many ask, what is the weight of dry timber. Speaking about this, you should definitely clarify the beams of which breed in question. After all, for your money you can make a bar even of mahogany.

We are talking about the most common types of wood. In our country, we are interested in the timber is made, as a rule, from pine, growing in central Russia.

Note! Being interested in weight, be sure to ask the supplier where the tree that served as raw material was cut down. For clarity, the Siberian pine is 1.3-1.4 times heavier than the pine from the middle band.

In addition to the above facts, you should not lose sight of the fact that the degree of moisture of a material is always different and there is no reference. Therefore, we can give you only the average weight, and it is 820-860 kg per cubic meter.

The process of building a house of dry beams

Note! The following instructions only stipulate the main stages of construction. For more details - refer to the video in this article.

Let's sum up

As you can see, timber can be a smart alternative to solid wood. Now you know about its advantages and disadvantages, and, perhaps, even decide to build a house on your own, without overpaying to developers. Stay with us, we will tell you a lot more interesting about this interesting material.
