The increasing number of builders gives preference to this material. This step is justified - at the pro-thinned-out bar optimum ratio of the price and quality.
The dry pro-thinned-out bar
The bar, as well as all materials for construction and repair, most often in specialized shops or in the markets is bought. But it is possible to buy and directly from the producer. Most often reviews of quality of those who already used services of this seller are sufficient occasion to buy from it or to look for another. But anyway, not to be disappointed in the purchase, it is necessary to know some signs on which the qualitative bar differs from goods inappropriate to norms. Most often for production of dry profile bar the preparation from if or pines which grows in the Kirov or Vologda regions is used. The choice of these breeds of tree is not casual, the natural pitches which are contained in coniferous breeds interfere with wood defeat by fungus.
Ratio price quality
The walls constructed their quality bar do not demand additional treatment as all manipulations are carried already out by the manufacturer and are included in the price. Not to overpay for low-quality goods, it is necessary to know properties of bar which meets all requirements of quality.
If on bar there are no propil, it increases clinking probability.
It is necessary to prick up the ears if in price of production company the sizes of bar of natural humidity and dry are identical since the dry bar usually gives drying less than raw. At qualitative bar at least cracks on layers. If there is opportunity to examine the houses built of this bar, it is necessary to make it as such survey can tell a lot of things about quality. The humidity on all volume has to be 18-20%, it can be checked the needle hygrometer with the special extended needles. If the bar is not dried in due form, it will shrink after construction that is in certain cases fraught for all design. Besides, in the course of drying the bar will become covered by cracks. Quite often in the course of drying there is such defect as twisting, and such bar during the work in due form is at once rejected by the manufacturer.
The wide spacing in the stated humidity of bar testifies to its low quality, neprosushennost.
The qualitative bar is hi-tech product which in the course of production has to undergo several types of various processing and demands the special equipment for this purpose. Thanks to it, a lot of things can be told about quality also on condition of shops of the manufacturer. Production of the pro-thinned-out bar has to include wood processing by antiseptics and nonflammable impregnations.
