Several decades ago, only logs and planks were used to build houses. The industry does not stand still, and since then more affordable and practical materials have been invented. Timber for building a house is one of them. Made from coniferous or deciduous trees, it is distinguished by strength, durability, and aesthetic appearance. The variability of sizes and lengths of up to 6 meters allows you to use the bars for different needs:

  • installation of the support frame;
  • laying floor joists;
  • construction of lathing for external and internal finishing.

Common raw materials for making construction timber are pine, spruce, and larch. Choose solid trunks, the thickness and length of which allows you to cut bars of the desired size.

Types of timber for building a house

The aesthetic and performance properties of lumber are influenced by the chosen processing method. According to production technology, timber for building a house is divided into types.

Having your own warm and reliable home is the dream of many people. A house built of wood is not only warm and reliable, but also environmentally friendly. Modern construction technologies offer various options for constructing wooden houses. Perhaps the best thing is to build a house from timber.

Timber minimizes the unpredictability of wood behavior during operation, and therefore is the optimal building material. The construction of timber houses is completed within one season, and the durability of these houses is at least 50 years. There are 4 types of timber used in the production of wooden houses: solid non-profiled, solid profiled, glued profiled and the so-called LVL timber (from the English LVL - Laminated Veneer Lumber).

Which one is better to use to get a house with the best price/quality ratio? Let's look at the pros and cons of each type.

Solid non-profiled

The timber is made from a single log, with a round edge cut off on four sides. For the construction of residential buildings, as a rule, 150x150 mm naturally dried timber is used.

  • low cost;
  • availability at any sawmill, that is, by choosing the nearest one, the issue of delivery of building material is easily resolved.
  • warping, shrinkage and cracking are the disadvantages of naturally dried wood;
  • wood defects - internal rot, flying knots, pests, fungus that appear after construction is completed;
  • the need for additional finishing - it is not subject to finishing, therefore it needs additional finishing;
  • the need for enhanced insulation of the seams - it does not have strict transverse dimensions and evenness of the cut, as a result - large gaps between the crowns;
  • low manufacturability - initially it is not suitable for the construction of walls, so it is necessary to make additional strengthening of the load-bearing walls and corners of the house, and this is unnecessary labor costs and time.

The price of a solid non-profiled timber with natural humidity is about 9,500 rubles. per cubic meter Plus the cost of finishing, mandatory treatment with fire-retardant compounds and additional work.

Conclusion: not the best material for building a house, but if you have the labor, patience, accuracy and attention to detail during construction, you can build a house from it, and for reasonable money.

Solid profiled

The timber is also made from a single log, only it is driven through special equipment, where it is given ideal geometric dimensions, a special lock profile is selected and, of course, planed to give it an aesthetic appearance.

  • low probability of warping - industrial wood drying technology makes it possible to achieve 10-15% humidity in the final material with virtually no deformation consequences;
  • does not require additional processing and finishing of the walls;
  • high precision connections (no gaps);
  • manufacturability - locking profiles greatly facilitate the construction process.
  • all possible wood defects mentioned above;
  • the need for additional time for shrinkage - after all, the existing possibility of shrinkage and warping of solid beams requires time for the finished walls to shrink.

The price for a solid profiled timber kiln-drying is on average 12,000 rubles. per cubic meter More expensive than non-profiled, but the final result is much higher in quality.

Conclusion: after treatment with fire-bioprotection, subject to construction technology, it is perhaps the best choice in terms of price/quality ratio, but you must be prepared to deal with possible “surprises” of solid timber.

Glued laminated timber

As the name implies, this type of timber is also calibrated and equipped with a locking profile. However, it is not made from a single log, but from separate blocks. They are glued together under pressure with a special glue.

  • all the advantages of profiled timber;
  • resistance to warping - thanks to the combination of different types of wood when assembling blocks for one log, further deformation, cracking is absolutely eliminated and shrinkage of the finished beams is practically eliminated;
  • no need for additional time for shrinkage - a house built from laminated timber does not shrink and is suitable for habitation almost immediately after construction is completed.
  • high price;
  • low environmental friendliness compared to solid timber - glue is a foreign material;
  • The natural circulation of moisture inside the timber is somewhat disrupted; due to the use of glue, moisture is not able to circulate between the layers, which may result in a slight disruption of the microclimate inside the house.

The price of laminated veneer lumber is on average 25,000 rubles. per cube - twice as expensive as a whole one. However, it should be noted that the cost of a project of wooden houses made of laminated veneer lumber is no different from similar projects of houses made of solid timber, and in the costs of the construction itself, the cost of the walls is approximately half of the entire construction budget. Consequently, the final house will not rise in price by much. In addition, when construction time is reduced, and when using laminated timber, as mentioned above, it is minimal, the cost of work also decreases.

Conclusion: If you have the opportunity to spend money on this expensive version of timber, then for the quick construction of a turnkey wooden house this is the best option, otherwise, it is probably better to stick with a solid profiled timber.

LVL timber

The manufacturing technology of LVL timber is reminiscent of the technology of laminated timber, only it is glued not from blocks, but from 3 mm veneer. Plywood is produced in almost the same way, only, unlike it, the wood of adjacent layers in LVL timber is located parallel to each other relative to the fibers. This allows you to process this type of timber in the same way as solid or laminated timber. When gluing, the density of the various layers is selected in such a way that the denser layers are located on the outside and the soft ones on the inside.

  • all the advantages of profiled laminated veneer lumber, only elevated to the rank of absolute;
  • increased strength and elasticity, as well as unlimited length, makes it possible to manufacture spans of any size;
  • increased moisture, fire and bioresistance.
  • highest price;
  • lowest environmental friendliness.

The price for LVL timber is about 35,000 rubles/m 3. This price makes it unprofitable when building walls of houses made of timber, but since it makes it possible to increase spans without the use of support pillars and beams, in combination with other types of timber it significantly expands the possibilities when choosing a project.

Conclusion: It is not a rational material for the construction of walls, but it is quite suitable for auxiliary structures.

All conclusions are quite clearly shown in the final table:

Thus, what the house will be like is always decided by whoever will live in it. Materials for construction must be selected based on your needs and available funds. From the analysis we can conclude that the most preferable for building a house from timber are solid profiled and glued profiled beams, however, there is also a place for other types.

When choosing wood for building a house, the question of which timber is best for construction interests any user. The number of buildings made of lumber is increasing, and, consequently, the demand for materials is growing, which allows manufacturers to offer more and more new products with a wide variety of quality and practical characteristics. As a result, the owner of the construction site is given a good choice, which needs to be carefully sorted out so as not to make a mistake when purchasing materials.

Types and types of timber

When planning to build a log house for permanent residence, it is worth remembering that wooden lumber looks like a long beam with a rectangular cross-section measuring 6 meters in length and 100-300 mm in thickness. This is a standard size, considered the most optimal for the construction of buildings.

Advice! If this length of timber is not enough, you should pay attention to elite Finnish wood: manufacturers offer elements up to 12 meters in length.

Materials differ according to various indicators, for example, according to the degree of processing; there are the following types of timber:

  • Raw edged/sawn;
  • Planed;
  • Polished;
  • Profiled.

According to the manufacturing method, lumber is divided into:

  1. whole;
  2. glued;
  3. hollow, supplemented with thermal insulation materials as filler.

Now a little more about the types of timber for building a house, modifications and characteristic features.

Edged timber

Considered a classic material, it is an element obtained by cutting the body of a tree. During processing, a solid log is freed from edges, the result is a building material in the form of a square beam with smooth, unprocessed, rough planes on all four sides.

The product has natural moisture, so it is possible to inspect the material for distortions that occur during improper storage. Section sizes: 250*250; 150*200; 150*150; 100*150; 100*100 mm. A large range of sizes allows you to choose the optimal batch of lumber to build your own.

Affordable price, high quality and practicality of the material are advantages, but among the disadvantages it is necessary to note the mandatory use of sealing material. It is mounted between the crowns so that precipitation does not get into the cracks, leading to the destruction of the building. In addition, there is a possibility that the lamellas will lose their shape when the natural drying process begins.

Planed, polished timber

This is an edged product made from wood, which undergoes a sanding process during processing. The result is lumber with smooth planes (on one, two or all sides), sometimes with a removed corner chamfer, which gives an aesthetic appearance and facilitates the construction process.

Advice! Dishonest manufacturers often pass off planed timber as sanded timber, so you need to be especially careful: the price of sanded timber is higher than planed timber. The differences are obvious: planed material does not have the smoothness of sanded material.

Profiled wood building material

It is considered the most progressive and practical for building a house. Each element is equipped with a locking connection, and, therefore, the crowns are adjacent with maximum density. In addition, the smoothness of both sides and the presence of fasteners make it possible to build a warm and strong structure, so the increased price of the product does not frighten consumers.

Advice! There are two profile options on the market: tongue-and-groove (German) and bowl-shaped (Finnish). The choice depends on the construction technology and the preferences of the developer.

Glued laminated timber

The material consists of several separate lamellas obtained by cutting the body of a tree, glued together. Thanks to pre-drying, as well as gluing taking into account the direction of the fibers, the product is considered one of the most reliable and high-quality for building a house. High-tech laminated veneer lumber does not shrink, does not require additional processing of wall panels and has high energy saving rates. Developers consider the lack of deformation and moisture resistance to be one of the main advantages of the material. The high cost of the material is due to its practicality and quality.

Advice! The material labeled LVL is also laminated veneer lumber, but has regular veneer as components. This causes it to be hard on the outside but soft at the core. It is considered the most expensive and high-quality wood material. Due to increased strength, elasticity and moisture-repellent properties, the timber is not subject to corrosion and does not rot; the product range has a different set of lengths, which makes it possible to call the piece goods universal for building a house.

Finnish timber

Elite wood with the following characteristic features:

  1. the annual rings in the lamellas have a unique direction opposite to each other, that is, they “look” at the center of the section.
  2. Strength and flexibility are also due to the vertical splicing of component parts every 4-6 meters.
  3. To obtain the finished product, thick elements are spliced ​​together, so the question is: which beam thickness to choose is of utmost importance. Standard technology recommends impregnating the elements with an adhesive composition for at least 2 cm, due to which the material is not completely impregnated, but only in the upper layers.

Important! Finnish laminated timber has a price that is 2-2.5 times higher than its Russian counterpart.

Composite timber materials

The packaged and hollow types of timber that have appeared on the market are also suitable for the construction of houses and buildings for various purposes. Representing a wooden block that is hollow inside, the structure consists of a pair of boards equipped with end elements and lintels.

The differences are:

  1. The package material is internally filled with insulation, which has a base made of mineral wool or foam glass.
  2. Hollow timber has no filling.

The main feature is increased energy-saving characteristics, which allows you to build a house with high energy efficiency indicators. Due to their technological features, composite beams are extremely affordable, but they are superior in quality to foam blocks, and experts say: a piece of composite timber product retains heat 2 times better than masonry made from brick, gas blocks and other standard materials.

Advice! For areas with high temperature fluctuations, the latest development is suitable - thermal timber. It is also a composite material consisting of hollow timber filled with polyurethane foam. The price category of a finished house is comparable to the cost of a house made of glued solid timber, however, when deciding what thickness of timber to take, choosing a glued one, you will have to make a wall of 390 mm, an alternative thermal timber can be taken of 160 mm. This means that with equal cost and energy saving indicators, wall panels made of composite thermal timber will be thinner.

When calculating the disadvantages and advantages of lumber, it is worth paying attention to the optimal humidity. This figure should be approximately 15-20%. Quality is achieved by drying in special chambers. The process should be carried out immediately after cutting the body of the log, and only then, the dried lamellas are processed, sanded, and so on.

Choosing the thickness of timber for building a house

Everything here is quite simple: standard timber for construction comes in square or rectangular cross-section with side dimensions of 100, 150, 200 mm. Some manufacturers offer sides measuring 250 mm on order, but here you will need to focus on the price of lumber. It turns out that the wall panel, determined by the dimensions of the beam, can be 100-250 mm thick. And the parameter is selected depending on the needs of the owner: the thicker the beam, the higher the rigidity of the structure. In addition, the wall must provide protection from the cold.

Important! The strength of wall structures is based not only on the thickness of the timber. When building a house, the presence and number of openings, the configuration of the walls and other indicators are taken into account; the assembly, or rather its quality, should also be taken into account.

Experienced developers advise choosing timber with a thickness of 100-150 mm for a one-story building, but parameters of 150-200 mm are better for building a house of 2 or more floors. It is also important to understand that when constructing an all-season heated building, it is necessary to insulate the walls from the outside; without this element, all modern houses will not meet accepted energy saving standards.

If we compare wall structures made of timber of different thicknesses, a weak dependence of the thermal resistance, determined by the thickness of the elements, is noticeable. For example, an insulated wall made of 150 mm timber is only 12-15% “warmer” than a wall 100 mm thick. Conclusion: with high-quality insulation and thorough waterproofing, it is enough to choose a good timber, as well as insulation. The calculation is approximately this: for walls made of 100 mm timber (100*150-200 mm), purchase mineral wool insulation of the same thickness (100-150 mm). This will be enough to maintain the high energy efficiency of the building.

But, nevertheless, when choosing what thickness of lumber to buy, it is worth remembering that building from thick timber has many other advantages, in particular, the structure will have less ability to warp when drying, greater strength and heat capacity.

Advice! Houses for seasonal living, bathhouses and outbuildings do not need to be sheathed with heat-insulating material, but it all depends on what size of timber is chosen. Experts recommend not to go cheap, but to build a bathhouse or summer house from lumber with a thickness of 150 mm or more. Heat accumulation is higher, which means that when warming up, the optimal temperature will remain longer.

Types of beam connections

The technology for constructing timber walls is different, but it is important to know the types of timber connections. Today developers offer the following typical connections:

  1. Angular. It happens with a residue (in the bowl) and without a residue (in the paw). With a remainder - a type that represents the protruding ends of the log house at a distance of approximately 0.5 meters. It is expensive, but heat loss is reduced and the strength of the building increases. Without remainder - the type when the end of the frame ends at the level of the wall. The connection occurs using staples or spiked plates with nails.
  2. Longitudinal connection is used when the length of the timber is insufficient. The increase in size occurs by connecting two elements. There are several ways:
  • tenon with key;
  • half a tree;
  • root thorn.
  1. T-shaped connection. It is used when it is necessary to fasten the outer and inner walls. The options are as follows:
  • by creating a trapezoidal symmetrical tenon in the log house;
  • creating a triangular tenon in a log house;
  • a locking groove on an insert tenon;
  • straight groove on the main tenon.

Despite the variety of connection types, there are some general recommendations:

  • the beam is rounded from the outside to minimize the threat of water accumulation in the grooves;
  • the place where the logs touch must be smooth and carefully polished.

It is a good idea to give the elements additional tightness by coating the joints with a composition of resin and sand.
