Due to its environmental friendliness, excellent technical characteristics and beauty, wood is rightfully considered one of the best building materials. Due to the unique properties of natural wood in wooden house always enchanting and unique microclimate. Finnish timber is popular with private developers due to its excellent technical characteristics and guaranteed quality.
What is the difference between Finnish-made laminated veneer lumber and domestic counterparts? Getting started building a house or country cottage, it is extremely important to choose the right material. Let us consider the production technology and features of the structure of the Finnish timber, so that an informed and balanced choice can be made.
Manufacturing technology and profiling
Since the construction of wooden houses has been relevant and in demand for many centuries, manufacturers are trying to constantly improve and modernize not only the production technology, but also the configuration of wooden lamellas. The main goal is to eliminate as much as possible the imperfections of wood, of which, by the way, there are not so many.
Glued laminated timber production technology
One of the significant disadvantages of conventional logs is geometry instability. The material expands under the influence of moisture and cracks and warps during sudden changes in temperature conditions.
The improved technologies for the production of glued structures made of wood, which were developed relatively recently, almost completely eliminate the disadvantages of wooden lamellas.
Profiled timber Finnish profile produced under strict observance of the following conditions:
- The logs are sawn into lamellas of the same thickness, which relieves the internal stress of the material and guarantees the stability of the lamella geometry. The timber does not deform and does not crack under the influence of adverse weather conditions;
- The low moisture content of the material (no more than twelve percent) guarantees minimal wall shrinkage over time. Finnish manufacturers carefully control the drying process. And since the technological process is fully automated, the quality of the material and a certain moisture content of the lamellas are guaranteed;
- After calibrating the boards and eliminating wood defects, the lamellas are spliced and sanded. This treatment allows you to achieve the perfect geometry of the beams;
- The lamellas are glued under pressure. As an adhesive, manufacturers from Finland use only environmentally friendly materials that do not affect the main technical characteristics of wood. Finnish glued laminated timber has the ability to "breathe", which creates a unique comfortable microclimate in the room.
Important. The strength and durability of the material is also given by the direction of the fibers of the glued lamellas.
The fibers of a cut of two adjacent lamellas are arranged in annual rings in opposite directions.
This arrangement of annual rings reduces internal stress, which significantly increases the strength of the material.
- Since the beams are profiled and trimmed with high precision, the assembly is easy to do with your own hands. The spike-groove system allows you to connect structural elements without gaps and distortions;
- Each detail is marked and packaged according to the specification, as required by the instructions, so the construction of a house from this material can be carried out in the shortest possible time.
Finnish laminated veneer lumber projects enjoy well-deserved popularity among private developers. A wooden cottage is not only a spectacular and beautiful building, but also a comfortable, durable and environmentally friendly building.
Profile - why it is convenient and reliable
The profiled beam is distinguished by the presence of a lamellar connection, therefore the crowns of the beams are tightly and reliably fastened.
There are two common types of profile:
- German profile - equipped with multi ridge (tongue and groove) joints;
- The Finnish profile of the bar is distinguished by the crown cups of the connection of the lamellas.
Important. Each manufacturer always has its own know-how for improving the profile connection.
But at the same time, the essence of the profiled connection remains unchanged - the lock longitudinal connection excludes the lateral shift of the material and excludes cracks and gaps during assembly.
Main features of a timber from Finland
Finnish timber belongs to elite building materials, since its cost is quite high. But almost everyone can afford to build a small bathhouse or sauna from Finnish wood.
What is the difference between a timber from Finland?
- The arcs of the annual rings of the boards to be glued are directed towards the center, and the core - outward. This arrangement of wood fibers guarantees increased strength and durability by reducing internal stress in the timber; (See also the article.)
- Different species of coniferous trees do not mix, which guarantees a beautiful and uniform tone;
- Bonding strength is ensured by vertical splicing every four to six meters, but no more than three meters. As you can see in the photo, this gluing technology guarantees an excellent appearance and an almost invisible seam;
- According to Finnish technology, only wide lamellas are used. This is due to the fact that the glue base soaks the wood by one and a half to two centimeters. Therefore, thin lamellas are almost completely saturated with glue and lose their ability to "breathe". Finnish timber with a thickness of 200 millimeters is made from three spliced lamellas with glue impregnation of no more than eight millimeters. This allows you to fully preserve all the positive technical characteristics of natural wood.
It is worth noting that a high-quality imitation of a Finnish timber in terms of technical and aesthetic characteristics is almost identical to an analogue, but the cost of such a material is much lower.
Advice. By purchasing construction material made of wood, give preference to a bar made of winter wood.
It is drier and more durable.
A distinctive feature of winter wood is a lighter color of the ends and the absence of fiber on the longitudinal cuts.
Experts advise checking the material in the following way.
Drop iodine on the cut of the timber - if the stain turns blue, it means there is a lot of starch in the tree, and this is a distinctive feature of "winter" lumber.
Advantages and disadvantages of laminated veneer lumber
Since the price of this building material is quite high, we will focus on its main advantages and disadvantages. Is the advertising characteristics so fair and is it worth overpaying for a foreign guaranteed quality? After all, there are a great many proposals from domestic manufacturers.
The "pluses" include the following characteristics:
- High resistance to deformation due to the absence of internal stress. The building will retain its shape and size and will not deform over time;
- Optimum humidity excludes long-term shrinkage of the building.
Advice. But glued laminated timber is wood, so the minimum shrinkage of the house still occurs over time.
Therefore, it is better to start interior finishing work a few months after the construction of the house.
- The wood guarantees excellent thermal insulation;
- Treatment of lamellas with antiseptic and flame retardant impregnations before gluing guarantees the strength and durability of the building;
- Short terms of work. a constructor that can be assembled even with your own hands. Marking of all parts and detailed instructions allows you to build a cottage in a month (not taking into account the foundation device).
On Russian market For a long time, Finnish glued beams have been very popular in wooden housing construction. It is known that glued laminated timber began to be produced in Finland about 25 years ago. The technological process for the production of timber was constantly being improved: new adhesives were selected, methods for orienting the lamellas of the timber, the thickness of the workpieces, etc. As a result, we got a very high quality material - Finnish laminated veneer lumber. Glued from sorted and specially selected lamellas, the Finnish three-lamellar laminated timber combines environmental friendliness with high strength and durability.
Why is Finnish timber so popular?
1. For the production of timber, special sawn wood is used.
This is a cut down the center of the log, grasping or removing the core, resulting in a radial cut in the wood that is least prone to warping. Used, as a rule, a thin meter (trunks of small diameter), or the top of the tree.
A special feature of laminated veneer lumber using this type of sawing is the orientation of the outer lamellas when glued with the core side out. This technology avoids significant cracks on the outside of the timber during operation.
2. Thick timber.
In the production of Finnish timber, lumber of greater thickness is used - 75 mm versus 50 mm from Russian manufacturers. Art Holz buys thicker lumber from an Austrian company that successfully harvests timber in the Leningrad, Arkhangelsk regions and Karelia.
3. Caring for health.
Just like Finnish companies, we were the first in Russia to use Purbond polyurethane glue in the manufacture of laminated veneer lumber, which is harmless to health due to the absence of formaldehyde and other components hazardous to humans.
The Art Holz company can offer you a house made of high quality Finnish timber, which fully corresponds to the technologies of Finnish housing construction.
