A wooden beam is increasingly used in construction. It can be used for the construction of low -rise residential and public buildings, products of small architectural forms (garden houses, arbors, wells, etc.D.) in a temperate climate.
Wooden houses from whole logs require significant labor costs and the presence of highly qualified carpenters. The process of such construction itself is longer, since each log is processed individually. Houses made of whole logs give shrinkage for two years up to 20 centimeters per floor. For this reason, it is impossible to proceed immediately to the decoration of the premises.
Currently, manufacturers offer to use a wooden beam for construction. The houses from the beam are deprived of the above shortcomings. In addition, the beam is not subject to the warfare and the occurrence of cracks, which can lead to a violation of geometry and damage to thermal insulation, moisture penetration and rotting. At the same time, they have all the advantages of wooden houses, such as naturalness and environmental friendliness, good thermal insulation and microclimate inside the house, breathability, convenience and comfort. The beautiful appearance of the outer surface does not require finishing.
A beam itself is a variety of lumber. It can be both whole and glued. The beam has a square shape in a section or have a finish on the outer side. Thickness and width can be from 100 mm to 400. It is made by sawing or offsetting logs from one or more sides or gluing several thin layers. The beam is clean, with a stupid or sharp overlap. Obzol is the edge that is partially sawn, or the side surface of the log, which was not subjected to processing. The bars can also be used as beams, risers, rafters, undergrounds and for the construction of doorbells.
