On modern market building materials there are several modifications of profiled timber. There are products with a semicircular front edge, straight, smooth with a chamfer of sizes 20x20 cm - 10x10 cm of square, rectangular cross-section.
Before you purchase profiled timber, you need to find out which profile is better, and how specialist consultations will help.
Regardless of the cross-section, type of decorative front edge, wood material, profiled timber can have one of two main profiles or an intermediate one. The main profiles include Scandinavian (Finnish), German (“comb”), intermediate profiles are combinations of tongues/grooves.
Scandinavian timber profile
IN Finnish version longitudinal locking connection, the timber has two wide tenons in the upper part with a recess between them. A mirror pattern is milled on the opposite side - a middle protrusion, wide grooves on the sides. When laying the walls of a log house, the profile is additionally thermally insulated and sealed with a sealant:
- jute, tow, polymer materials, sealant fill the lower part
- the middle wide tenon of the upper crown fits into a reciprocal groove with a small gap intended for shrinkage of the structure when the material is completely dry during operation
Classic rounding is similar in installation scheme to this version of the beam profile. Profiled products with a Scandinavian longitudinal lock are more convenient for redevelopment and the manufacture of extensions:
- The crowns are easily disassembled and installed in place
- There is no complex cut when making bowls
Having chosen profiled timber for construction, you need to decide which profile is best for a particular project. Many experts believe that the sealing tape, which is used only in the Scandinavian type of longitudinal lock, adds reliability to the joints.
German timber profile
Design wooden houses with longitudinal locks of the German timber profile ensures a permanent connection after a short period of operation. After drying, the labyrinthine circuit is reliably jammed, and the walls become inseparable.
Externally, the locking connection resembles a comb in cross section, which is where the material gets its name. Depending on the cross-section of the profiled beam, there may be 4-6 medium grooves on the edges (20x20 cm, 10x10 cm, respectively).
- in this case, the geometry of the products is unstable;
- problems arise in the construction area when the tenons/grooves do not match;
- when choosing a German profile, a seal is not used - the grooves are too small to accommodate foreign material;
- there is an opinion that German locks are easier to operate due to the lack of insulation;
In the classic Finnish timber profile, the bowls are semicircular; for sealing, a wide tape is placed in the middle part, and a sealing cord is placed in the side grooves. In practice, straight bowls are more often used, compaction only in the central part of the profile or only on the sides polymer materials. In the German profile, the sealing technology in the bowls is selected individually, depending on the gaps present in the connection. Complex labyrinth geometry is considered optimal for the absence of blowing through the walls.
Experts, answering the question: “what profile for construction wooden house better?" - they agree that, in all respects, the material with factory bowls wins. Their production in the building area is too complicated, the gaps increase, requiring excess sealant, and the aesthetics of the perception of the log house decreases.
When building wooden houses, timber with various types profiles: several teeth, comb or “Finnish” profile. What are these types of materials, why are they good and how do they differ from laminated timber? Let's try to clarify all these questions.
About glued and profiled timber
Glued laminated timber is made from a set of boards glued to each other, and profiled timber is a monolithic log.
The timber with the profile dries for about a year. The glued version is sold dried.
The sound and heat insulation properties of laminated veneer lumber are lower than those of profiled timber. The glue between the boards can sometimes dry out, and this reduces the thermal insulation of the wall.
Profiled material is cheaper.
Laying profiled timber requires a certain level of professionalism from installers.
Properties of various types of profiled material
Comb
A “comb” shaped beam is a product with a large number of cut teeth.
Their presence is a big plus, since there is no need for insulation. The tight contact of the teeth prevents cold air from penetrating through the walls.
The disadvantage of such materials is the complexity of the connection. With changes in temperature and humidity, the original shape is lost. Logs sometimes have to be fastened together using a sledgehammer, which can compromise their integrity.
If the “combs” are connected correctly, you will get very warm walls.
Best type for cold northern regions.
Finnish type profile
In terms of installation, this is a more convenient connection. The profiled beam has two tenons along the edges, which greatly simplifies the assembly process. Walls with this profile are practically not subject to shrinkage.
Proper connection requires experienced professionals.
In order for the profile to have good thermal insulation, insulation should be laid between the logs.
More suitable for regions where the climate is not very harsh.
Beam with three to four teeth
A more versatile option with wide studs. They practically do not deform during storage.
Collecting such a profile is much easier.
Each type of profiled timber has its own pros and cons.
Advantages of profile beams
This is a 100% solid wood monolith.
Profile basis - tree species from pine, spruce.
Products are processed using high-precision equipment.
The grooves are connected without gaps to the tenons of the opposite beams.
The purchase of various fasteners is excluded.
There is no adhesive in the timber. Therefore, it is durable even after time. There are no emissions harmful to human health. Therefore, the indoor microclimate, due to the absence of artificial layers, is quite comfortable.
In houses from profile material cool in hot weather and warm in cold weather.
Walls made of profiled timber reduce the cost of maintaining heat during the cold season.
It is not necessary to finish the walls. They already have an original natural look.
Profile beam not processed during construction protective compounds. This procedure is performed in a factory autoclave, which is much more efficient than manual coating.
There are also some disadvantages.
Disadvantages of profiled timber
Finishing of the house should be done only after it has settled. And this is about one year.
Dried logs may develop cracks.
The appearance of the buildings does not pretend to be modern style. Log walls look natural. Houses made from profiled timber are chosen by developers who give preference to naturalness and environmental friendliness.
One way or another, the pros of the profiled material are much greater than the cons. Depending on certain conditions, it is successfully used in construction.
is modern lumber, usually made from spruce, pine, cedar or larch, which is given a certain geometric shape. Having found out what profiled timber is, let’s clarify its main benefits, because in construction and subsequent operation it is considered more convenient than traditional cylindrical lumber.
So, this massive lumber is obtained from planing on 4 opposite sides solid log. Perfect mechanical restoration gives us a beam that is even along its entire length, and its humidity is within 20%.
Material properties
Some companies produce such timber directly during the installation of the house. And it is much more economical when selecting logs the right size: we often need short lumber, which means we can use a smaller and cheaper log. By the way, raw logs are deformed when delivered for construction, which will complicate the construction of a house.
Advantages of profiled timber
Solving the question what better timber or profiled timber, let us specify the advantages of a high-tech new product:
- speed and ease of construction of walls from quadrangular profiled material;
- the optimal dimensional accuracy of these products, manufactured on special sawmills and milling machines, guarantees excellent quality of work at the level of eurolining;
- The presence of planting cups, grooves for insulation, and vertical cuts in this type relieves tension in the wood and prevents cracking when it dries.
Now we know about profiled timber - that it is beautiful, warm, saves time and money. In addition, a house built from of this material, after settling it does not require caulking with insulation at all.
Note! The ideally precise design of the timber does not allow even the smallest drops of rain to settle between the logs, so the log house is reliably protected from rotting.
Obviously, walls made of such spectacular natural wood are very attractive and do not require expensive siding or labor-intensive plaster.
Varieties
Advice! Let's determine the degree of drying. After all, the timber is voluminous, and high-quality drying in compliance with technology will prevent shrinkage of the structure and deformation of the walls.
We clearly understood what profiled timber is, since now they also produce laminated veneer lumber, which does not shrink or deform, but also does not guarantee environmental safety: We cannot be sure whether the glue used in its production is harmless.
An ideal healthy microclimate can only be created by natural wood. And its price and high quality will satisfy our requests.
The instructions clarify the methods for producing this lumber and its varieties.
Classical
- Rectangular, simply sawn or carefully planed with a section of 200x200, 200x150, 150x150, 150x100, 100x100.
- Cracks and large shrinkage of up to 5% of the height of the house are possible within six months.
- We can minimize this disadvantage by cutting the logs.
- The cost of such log houses is 20% higher than their analogues made of round logs. Therefore, when deciding whether a profiled beam or a regular one is better, let’s take this into account.
Latest advanced cross-matching configuration profile:
- D-shaped;
- Tongue and pile.
It is more expensive than a square, but provides maximum joint rigidity.
Carriage
Carriage is a type of lumber obtained by trimming a log from 2 opposite sides.
- It is possible to make a carriage with your own hands.
- Made according to this " Norwegian style» half beam is a refined product for an exotic wild log house.
- The structure is light, beautiful, warm, with natural ventilation, does not require a powerful foundation and heavy equipment.
- Columnar.
Comparison of rounded material and profiled
- Design. The spirit of centuries emanates from rounded fairy-tale log houses, however a large number of cracks is a disadvantage that profiled timber does not have. Longitudinal compensation slots will eliminate possible cracks.
- The rounded one slides and is mobile during laying, subject to both longitudinal and helical deformations. Features of laying a quadrangular beam: the flat sides are easy to fold, like a Lego construction set, and are less deformed.
- Which lumber is warmer? Seat the cylinder is 3 times thinner than the profile. Cold bridges form here, and there are no freezing points in the profiled wall, but the teeth and grooves in any log will provide the house with warmth due to the complete absence of ventilation.
Profiled timber this is modern construction material which is made from coniferous trees by milling and planing. At the same time, a special profile is attached, such material is easy to lay, thanks to the tenons and grooves, the walls are assembled from it like a constructor, which significantly saves time and money, the walls remain geometrically smooth, thanks to the rigid coupling, in the form of a lock and do not require further finishing.
Types of profiles and sizes
Exists three main sizes profiled timber: (dimensions are indicated in clean form)
- 140 per 90 mm (wall thickness 9 cm) - For country houses and mainly goes like a partition beam
- 140 per 140 mm (wall thickness 14 cm) the most popular timber size, the so-called “golden mean”
- 140 per 190 mm (wall thickness 19 cm) used for cottages and houses for permanent residence
By profile type:
- Finnish- the beam profile has two pronounced spikes
- Comb- has a large number of thorns
- Scandinavian- this is a subspecies with a comb profile.
- Lunar- or in other words, a “block house”, semicircular on the outside and smooth on the inside, the most popular look timber
- Smooth- the profile is smooth on both sides, with beveled chamfers.
By degree of humidity:
- timber natural humidity (25-40%)
- Chamber drying timber (forced) (no more than 20%)
By harvesting season:
- Winter forest(raw materials for timber, prepared in winter)
- Summer forest
Production technology
For the production of profiled timber they use conifers wood, spruce or pine. We take blanks of unplaned timber measuring 150 by 100, 150 by 150 or 150 by 200 mm, depending on the size we want to obtain. Using the milling method, 0.5 cm is removed from both sides, while the beam is given a profile (a semicircle on one side or even sides, two tenons or a comb), in the other two a profile is formed in the form of a “tenon and groove” At the output we get a planed timber profiled on 4 sides, the whole process takes 1-2 minutes per 1 piece. (beam 6.0 meters long). Profiling is carried out on special four-sided planing machines profile cutters.
The photo shows standard blanks of unplaned timber, ready for milling and profiling

Important: Finish walls made of such timber must be sawn down and cut into a root tenon (another name for a “warm corner”) or its variety, dovetail. Between the crowns they always lay interventional insulation jute.
Cutting the corners of houses, only in the root tenon, according to GOST 30974−2002
Jute insulation between each crown of timber main walls and partitions
Thanks to the tenons and grooves, the timber is connected into a rigid, geometrically even structure
For reference:
In one cube of timber 150 by 100 mm - 11 pcs.
In one cube of timber 150 by 150 mm - 7.0 pcs.
In one cube of timber 150 by 200 mm - 5.5 pcs.
This affects the cost of a log house; for example, a house of equal size and area made of 150 by 200 mm timber will always be more expensive. Since the number of beams in a cube is smaller, which means more cubes are needed for construction, take this into account when requesting or planning the construction of a future home
The choice of timber profile does not affect the cost (you can choose either a lunar profile (under the “block house” from the outside) or even on both sides).
- We have own production profiled timber.
- There are two in production drying chambers, at your service, chamber drying timber.
- And also timber for winter harvesting.
Profiled timber is a high-tech material used in all branches of construction. They make it from coniferous trees: larch, pine, cedar, spruce.
Profiled timber differs from ordinary timber in its appearance, as well as in its functional properties. In this article we will analyze in detail the functional differences between different types of timber.
If speak about appearance, then the main thing honors is the side that faces the street when building a house. It can be flat, or it can have a semi-oval shape, and the side that will be in the house is always flat.
However, during construction, the most important thing is the upper and lower parts of the beam; they represent a system "Tongue and groove" for perfect joints. This means that you can build a building from timber in short time and high quality!
Sometimes the gap between the tenon and the groove is made larger and placed there jute insulation, thereby reducing the thermal conductivity of the house.
Profile beams are divided into types according to the following parameters:
- Raw materials
- Geometric profile
- Size
- Production technology
- Drying degree
Let's focus on the two most important parameters and consider them in more detail - production technologies and drying. According to production technology timber happens:
- Whole. This variety is obtained from planed on four sides solid log. This is the most cheap option construction.
- Glued. This latest trend V modern construction. This material is distinguished by its super strength, aesthetics, and durability compared to solid timber.
But the technology for manufacturing glued analogues is very expensive, and therefore not everyone can afford such building material.
By degree of drying timber happens:
- Dry. Here the criterion is the percentage of moisture in the timber. If the material has undergone a drying process, then there should be moisture in it less than 20 percent. This is dry timber.
- Natural humidity. Timber with natural moisture may have percentage about 50. The lower the moisture content of the timber, the higher its performance, and therefore higher cost.
Basic timber dimensions
In any case, before you start self-installation , it is advisable to consult with a specialist in this field, read literature on this topic, watch videos that clearly show the process.
