Types of timber for home construction and their features

+ The merits of a solid bar

1. Accessibility. Since the process of manufacturing a solid timber is not difficult, then you can buy it almost everywhere, with minimal waiting time from order to delivery of products.
2. The low cost of this material is due to the simplicity of its manufacture and the lack of costs for drying wood.
3. Environmental friendliness. This timber is able to regulate the level of humidity in the house, absorbing the excess moisture that accumulates in the premises in the process of human life.

- Disadvantages of a solid bar

1. Difficulty laying log house. Since the timber does not have longitudinal profiled furrows, it is rather difficult to achieve a high-quality surface of the house walls when making a log house.
2. Increased construction time. Given that the solid timber has a natural moisture content, after the end of the felling device, it must undergo shrinkage, which can last more than a year. This process includes additional work on filling the joints with a compactor.
3. Cracking of a non-profiled bar. Shrinkage of a house made of wet timber causes cracks, twists and bends to appear in the timber, which increase the gaps in the joints between the crowns.
4. The spatial rigidity of the house throughout its operation is ensured only by the strength of the dowels, which keep the rims in a predetermined position, resisting the possible deformation of the beam, especially during the shrinkage of the log house.
5. Significant costs for finishing and insulating work. A solid timber house needs finishing work both inside the building and outside due to its minimal aesthetic appeal.
6. Exposure to fungus. Natural shrinkage of wood does not eliminate the risk of fungus. It can be eliminated with the help of modern means of protection, but this is another additional item of expenditure.

+ The merits of a solid profiled bar

1. The presence of longitudinal grooves on a timber reduces heat loss through inter-joints and increases the spatial rigidity of the finished house.
2. The identity of the dimensions of the cross-section of the beam, provided by high-tech manufacturing, significantly reduces the time of assembly of the log house and improves its quality. In addition, additional longitudinal cuts in the timber remove the internal stress of the wood, which appears during the natural shrinkage of the timber, which reduces the risk of significant cracks and twisting.
3. The quality of the side surfaces of the finished walls reduces the cost of finishing them.
4. Environmental friendliness. Made of solid array, profiled timber has the ability to regulate the humidity of the air in the room, providing natural ventilation.
5. The cost of this timber compared to non-profiled is the most expensive by 40-50%. But when negotiating the price you need to take into account the moisture level of the timber offered to you.

- Disadvantages of a solid profiled bar

1. Shrinkage of the house.If the profiled bar has a natural moisture content, this will require a long break in construction, during which the log house will shrink. The closer the moisture percentage to the natural level of wood, the longer (up to 12 months) the shrinkage process of the finished log house of your house will take place.
2. The appearance of cracks during shrinkage. Yes, they will appear, as it is typical for massive wooden elements, although their sizes will be minimal.

+ Advantages of glued profiled beam

1. The terms for building a house are reduced due to the fact that the frame of this material does not need long shrinkage.
2. Made of dry wood, such a timber retains its geometrical dimensions throughout the life of the building.
3. The surface of the walls of the house from this timber is almost ready for finishing immediately after the end of the felling device and does not require additional preparation for applying varnish or painting.
4. There is no risk of cracking due to the construction of individual slats.
5. The strength of such a bar increases by 1.5 times compared with an analog made of solid wood, which positively affects the strength and durability of the whole house.
6. Good heat saving performance. The high quality of the horizontal joints between the flanges of the log house, as well as the absence of cracks in the timber provide a comfortable temperature inside the house, while reducing heating costs.
7. Possibility to order a bar of the desired section according to your project, since it is not tied to the need to search for solid logs of the required diameter.

- Lacks of glued profiled bar

1. The cost of glued profiled timber exceeds the cost of its analogue of solid wood by 2.5 times;
2. Despite the fact that all the adhesive compositions used in this technology are developed on the basis of PVA and comply with permissible standards, the ability of wood to "breathe "significantly reduced;
3. Since this technology of manufacturing a timber has been developed relatively recently, there is no verified data on its behavior in the construction of a house through the floor century and more.

+ The advantages of the thermo-bar

1. The increase in heat-saving indicators is 1.3-2.1 times as compared with a laminated timber, which significantly reduces the cost of heating such a house.
2. The cost of a thermo-bar is similar to the cost of a profiled glued timber.
3. No shrinkage.
4. Willingness of the surface for finishing immediately after making a log house.
5. Strength and durability of the walls of this material.

- Defects of the thermal bar

1. Material is present in the building materials market relatively recently. There is no information about his behavior in building structures in a few decades.
2. Walls of the house do not “breathe” as expanded polystyrene is an air-tight material.
