In construction work, wooden products were used at all times. Modern products are made on perfect ones woodworking machines and are used in the finishing of premises, as well as in rough work. The appearance of lumber is, of course, beautiful, but its most important advantage is its ecological value. The tree creates conditions for a healthy microclimate that cures various diseases.
The latest technologies used for the production of wooden products make it possible to achieve excellent strength indicators. The technological process includes careful cutting of logs along the grain, precise sawing. On special machines, blanks are produced first, and then bars, boards, and bars.
A fairly large volume of the output is made from conifers. For example, pine has an optimal resin ratio. Therefore, a change in humidity will not harm pine products in the form of rotting. Such remarkable characteristics of pine lumber are taken into account during construction. Pine beams are required during the construction of the building. There are much less resinous substances in spruce than in pine. However, it is perfectly suitable for mounting the supporting structure.
Modern wooden materials do not have any disadvantages at all. In the old days, when there were no different impregnations to prevent wood from rotting and insect attacks, wooden materials could not be used everywhere. Today's possibilities allow to exclude even the deformation of wooden products when climate conditions change, namely humidity, which is the cause of all negative manifestations.
Such shortcomings are eliminated thanks to effective methods. For example, one of the ways is to dry the tree. A special drying chamber is used for this. After the drying operation, wooden products cease to crack or undergo deformations. The tree becomes pliable and easy to work with. Sawmill products are dried to a certain degree.
The most valuable are boards with low humidity. Lumber with high humidity is used for roofing. So, wooden products with humidity up to:
• ten percent serves for the production of parquet;
• fifteen percent goes to the production of floor boards, door boxes, plinths;
• eighteen percent is suitable for crates, rafters.
