Planed beam is a building material widely used in construction. It is used for attaching a block house to it, lining, imitation of timber, for lathing walls and ceilings, lag for the floor. From the beams of certain species of trees, interior partitions, doors and furniture are produced. The thickness of the beam is at least 10 cm, if it is less, then this is already a bar.
Planed timber can not be attributed to durable building materials, but nevertheless, with proper care, it can stand up to a hundred years. This type of timber is cut out from a whole log, all four sides are processed with special tools. It can be either square or rectangular, while its width should not exceed a thickness of more than two times. The beam is planed to the cleanliness of the first class.
In construction, you can not do without bars, but at the same time not only planed is used. Profiled timber is also very popular. Although it costs more than a planed beam, it is not subject to deformation, does not shrink, and no cracks appear on it. Planed timber has natural moisture, so that it dries, the boards need to be aged for about a year. In addition, the beam can present a rather unpleasant surprise, twisting and forming gaps.
After natural drying, the beam must be caulked. It can only be painted with breathable colors. The profiled beam does not need caulking. But be that as it may, it still requires some attention in the assembly, because it is not so simple to build airtight walls from profiled timber.
Planed and profiled - these bars are completely different, but they have a lot in common. Both one and the second are quite fire hazardous, therefore it is necessary to treat them with special means. It must be remembered that this is primarily a tree that is susceptible to decay and destruction under the influence of fungi, atmospheric phenomena, insects. In order to extend the operational life, planed timber must be treated with an antiseptic and renewed impregnation from time to time.
In construction, the boards are used, both natural humidity and dried in a special chamber. Dry planed timber has a moisture content of only 8 - 12%, while dried planed timber has a moisture content of about 18%. In construction, both the first and second types of wood can be used , which is preferable - it already depends entirely on the type of work.
The beam is used in the construction of any structures, because it has established itself as a light, strong and durable material with a low coefficient of thermal expansion. The price for it is quite acceptable, since the beam is made very simply, and the raw materials are not so valuable.
Dry timber is widely used for the construction of residential premises, it is good for creating eurolining. This material has the lowest humidity because it is dried in a special chamber. However, it does not lose its properties and remains a completely ecological material.
The bars should be stored in a well-ventilated room, with little humidity. They stack in stacks, while the air should circulate normally. For safety, the boards are covered with roofing material.
