An increasing number of people are inclined to build environmentally friendly chopped houses. The market instantly reacted to ever-increasing demand: the arsenal of building materials continues to be replenished with various types of semi-finished wood products, which indicates an active phase of technology development in this direction.
A high-tech beam or a classic log - which is better for building a wooden house
Puzzled by the construction of a building made of wood, you should familiarize yourself with the nomenclature of raw materials. It is the form of the latter that determines the principles of construction technology and the final cost of the issue. The following types of lumber are common:
After analyzing the task from the aesthetic side, it becomes obvious that the log house in the classic old Russian style looks much more elegant than a house made of standard-format lumber. To unleash the fundamental uncertainty in the question of what is better to choose from the proposed types of timber or logs , it becomes possible only after a detailed study of the advantages and disadvantages of each.
Prefabricated blanks obtained by gluing several previously dried boards were actively used in the construction of buildings in the early 20th century. Modern technology for the production of glued lumber allows you to get almost natural building materials with exemplary properties. The undoubted advantages of blanks of this type can be considered:
- the resulting shrinkage value is negligible, which makes it possible to immediately begin installation of double-glazed windows and doors and to the interior decoration after the construction of the building;
- hollow fiber structure prevents the occurrence of a phenomenon such as warping;
- giving preforms at the final stages of production a specific profile significantly reduces the complexity of construction;
- with the right choice of section, the need for additional cladding of the building disappears;
- the likelihood of cracks and foci of decay is reduced to zero.
When deciding which beam is best for the home , it is strongly recommended that you pay attention to the type of product made of recycled wood in question. There are only two reasons that can push a consumer away from using a glued product:
- quite high price - about 25 thousand rubles. for 1 m3 ;
- lack of air conditioning function, which is natural for solid wood, due to artificial layer (glue);
Solid profiled lumber
Named in this way, the blanks are a monolithic product milled from a log. A characteristic feature is the presence of profiled cut-outs that serve as a barrier to atmospheric air currents and facilitate the connection of semi-finished products with each other .
The logical solution to the bilateral problem of which material to choose, timber or log, and what is better to use from the point of view of reducing time costs and economic feasibility, will be a shift in emphasis towards the use of profiled lumber . The solution is a priori supported by such positive aspects :
- there is no need for a labor-intensive caulking operation;
- the consequence of drying - 4-10% against 13-17% for logs;
- assembly processes intensified;
- operations for the formation of angular joints are less complicated than the cutting of the corners of a log house.
It is worth noting that in this class there are two subspecies of materials : a chamber-dried timber and natural humidity . The main difference is that the former hardly shrinks over time, as a result of which the probability of cracking is reduced. However, a dried tree can absorb atmospheric moisture and change geometry. Therefore, when using chamber drying lumber, it is strongly recommended to reduce the time interval between the final production of the semi-finished product and the start of wall laying to a minimum . The cost of raw materials is about 10 thousand rubles. for 1 m3
Pay attention to this material only if you are looking for a solution to the question of which beam is best for a seasonal home (for example, a summer house), which does not have special aesthetic requirements.
Budget material has a combination of such disadvantages :
- blanks with straightforwardness necessary for construction - a rarity in this class;
- the need for an expensive facade and interior decoration;
- tendency to crack;
- the absence of a tongue-and-groove system increases the likelihood of blowing seams;
- since the material is naturally moist, the likelihood of a fungus infection is increased.
Simple and round log
The cost of a pre-processed round wood profile is comparable to the price of a profiled semi-finished product. Focusing on the fact that it is better to use a log or timber , it should be borne in mind that the construction of a log house even from rounded lumber is a complex process that requires a lot of time and a set of skills related to the creation of corner joints . Caulk interventional joints when using logs is necessary several times. To organize the inner lining of the log house is a task subject to a highly skilled worker. The use of a simple log further increases the complexity of construction, since it is necessary to carry out a diameter adjustment and form an interventional groove . The lumber in question is also prone to cracking. Of the logs quite often build country houses and baths.
And yet, what is the best way to use the beam for the construction of a house, cottage or suburban building?
During the construction of a massive chopped building for year-round use, it is recommended to use glued lumber , which has high load-bearing capacity and is not prone to cracking. The downside of this solution is one - the lack of natural air exchange through the wall .
Considering which timber is better to use for a small private house , you should focus on the profiled lumber of chamber drying . The accuracy of the mutual arrangement of the surfaces of these blanks is very high, the resistance is also at the level, and the walls "breathe". The only requirement is the inadmissibility of storing blanks for a long time .
It is advisable to use edged timber in the construction of "seasonal" buildings and outbuildings due to the lack of solidity of the walls of the structure .
Analysis of the nomenclature of building materials from wood shows that glued workpieces are the most technologically advanced. Pre-heat-treated profiled lumber has optimal properties. It is advisable to use logs in pursuit of the aesthetic component of the building. When using the latter, it is worth remembering that the decisive influence on the thermal conductivity of the overlap is not the diameter of the log, but the width of the interventional groove.
