A beam is a log evenly sawn from four sides. It happens natural moisture, profiled, glued, still distinguish planed timber. The cheapest and environmentally friendly material for residential construction is a bar of natural humidity. The rectangular cross-section makes it convenient for construction; a house from a bar of natural humidity is being built for about 20 days. Bypassing the drying stage in special chambers, this material loses moisture gradually, ready for use, it is more humid than planed, past chamber drying.
Manufacture
A quality beam is obtained from any wood, but when using it, the properties of the breed are taken into account. Lumber is obtained by processing a regular round log at sawmills. The material has a standard section of 100 x 100 mm or 200 x 200 mm. The log can be carefully sawn into boards of the right size and with the help of a band saw, a multi-saw machine.
Properties of timber from different types of wood
Pinestrong and light, its wood has a pleasant yellow color, easy to process. The resin protects it from decay, contributes to the fact that the product will withstand weathering. Drying does not cause warping of pine wood; its loose surface absorbs varnishes and paints well.
Spruce - the second most common type of tree. Having a larger number of knots, it is worse than pine in processing, while it contains less resin, which makes it more vulnerable to moisture.
Cedar surpasses pine and spruce in technological characteristics, but is more prone to decay in a humid environment.
Hardwood not protected by resins is used for interior decoration of buildings.
Storage of finished products
The finished timber of natural humidity is stored neatly stacked in piles under a canopy or in ventilated warehouses. Uneven moisture or a scorching sun can cause cracking, warping or decay.
Benefits
- Ecological cleanliness is ensured by the absence of glue.
- Beautiful appearance of natural wood.
- Universality in application, simplicity in work.
- Budget cost for construction.
- No need for additional external processing.
Disadvantages
Continued gradual drying during operation often leads to cracking. To avoid their exit from the outside, special cuts are performed in advance. It is better to build buildings from this material in spring and autumn, then the evaporation of moisture will be uniform and gradual.
To keep the exterior of the building decorative, it is necessary to regularly update the antiseptic protective coating.
Using
From this material erected houses, farm buildings, baths, gazebos. The building, built according to the rules, will evenly shrink, will be strong, durable and beautiful; shrinkage of a bar of natural humidity occurs within six months.
It speeds up construction even more, makes it easier to use a beam with a cut profile; profiled bar of natural moisture has grooves for reliable connection of adjacent parts; planed profiled timber is the most geometrically stable lumber.
A wooden house from a budgetary timber looks no less respectable and is not inferior in quality to buildings made of more expensive materials.
