Finnish glued laminated timber is a new generation building

Thanks to environmental friendliness, excellent technical characteristics and beauty, wood is considered to be one of the best building materials. Due to the unique properties of natural wood in a wooden house, there is always a charming and unique microclimate. Finnish timber is popular among private developers due to its excellent technical characteristics and guaranteed quality.

What is the difference between Finnish-made glued laminated timber from domestic analogues? Starting the construction of a house or a country cottage, it is extremely important to choose the right material. Consider the production technology and features of the structure of the Finnish timber, so that you can make a reasonable and balanced choice.

Production technology and profiling

Since the construction of houses made of wood for many centuries is relevant and in demand, manufacturers are constantly trying to improve and modernize not only the production technology, but also the configuration of wooden lamellae. The main goal is to eliminate the disadvantages of wood, which, by the way, is not so much.

Production technology of laminated veneer lumber

One of the major drawbacks of conventional logs is the instability of the geometry. The material expands under the influence of moisture and cracks and warps when sudden changes in temperature.

Improved technologies for the production of glued wood structures, which were developed relatively recently, almost completely eliminate the drawbacks of wooden lamellae.

Profiled timber Finnish profile is produced under strict observance of the following conditions:

• Logs are sawn into lamellae of the same thickness, which relieves the internal stress of the material and ensures the stability of the lamella geometry. Timber is not deformed and does not crack under the influence of adverse weather conditions;
• The low moisture content of the material (no more than twelve percent) ensures 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 lamellae are guaranteed;

• After the boards are calibrated and the wood defects are eliminated, the lamellas are spliced ​​and ground. This treatment allows you to achieve the perfect geometry of the bars;
• Gluing lamellae is carried out under pressure. As an adhesive, manufacturers from Finland use only environmentally friendly materials that do not affect the basic technical characteristics of wood. Finnish-made glued laminated timber has the property of “breathing”, which creates a unique comfortable microclimate indoors.

Important. The strength and durability of the material also gives the direction of the fibers of the glued lamellae. The cut fibers of two adjacent lamellas are arranged in annual rings in opposite directions. This arrangement of annual rings reduces the internal stress inside the laminated timber, which significantly increases the strength of the material.

• Since the bars with high accuracy are profiled and protruded, the assembly is easy to do with your own hands. The spike - groove system allows you to connect structural elements without gaps and skews;
• Every detail is labeled and packaged according to the specification, as required by the instructions, so the construction of the house of this material can be carried out as soon as possible.

Projects from Finnish glued laminated timber are deservedly popular 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 bar is characterized by the presence of the locking connection of the lamellas, therefore the rims of the bars tightly and securely fastened.

There are two common types of profile:

• German profile - equipped with a lot of combed (tongue-and-groove) connections;
• The Finnish profile of a bar - differs in crown cups of connection of lamels.

Important. Each manufacturer company always has its own know-how to improve the connection profile. But at the same time, the essence of the profiled joint remains unchanged - the locking longitudinal joint eliminates the lateral shear of the material and eliminates cracks and gaps during assembly.

The main features of timber from Finland

Finnish timber belongs to the elite construction materials, as its cost is quite high. But almost everyone can afford to build a small bath or sauna from Finnish wood.

What is different from Finland bar?

• The arcs of the annual rings of the glued boards are directed toward the center, and the core is outward. This arrangement of wood fibers ensures increased strength and durability by reducing internal stress in the timber; (See also the article How to choose a bar: selection by parameters.)

• Different species of coniferous trees do not mix, which guarantees a beautiful and uniform tone;
• The strength of gluing is ensured by splicing vertically through four to six meters, but not more than three meters. As can be seen in the photo, this gluing technology guarantees a great appearance and an almost imperceptible seam;
• According to the Finnish technology, only wide lamellas are used. This is due to the fact that the adhesive base permeates the wood a half to two centimeters. Therefore, thin lamellae are almost completely impregnated with glue and lose the ability to "breathe." Finnish timber with a thickness of 200 millimeters is made from three spliced ​​lamellas with glue impregnation of not more than eight millimeters. This allows you to fully preserve all the positive technical characteristics of natural wood.

It should be noted that the high-quality imitation of the Finnish timber is almost identical to the technical and aesthetic characteristics, but the cost of such material is much lower.

Council When purchasing building material from wood, give preference to timber from winter wood. It is more dry and durable. A distinctive feature of winter wood is a lighter color of the ends and the absence of fiber on the longitudinal saws. Experts advise to check the material in the following way. Put iodine on the cut of the timber - if the stain turns blue - it means there is a lot of starch in the wood, and this is a distinctive feature of “winter” lumber.

Advantages and disadvantages of glued laminated timber

Since the price of this building material is quite high, we will focus on its main advantages and disadvantages. Is the advertising performance fair and is it worth overpaying for foreign guaranteed quality? After all, offers from domestic manufacturers are great.

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 eliminates long-term shrinkage of the building.

Council But glued laminated timber is wood, so minimal shrinkage of the house eventually occurs. Therefore, it is better to start interior finishing work several months after the construction of the house.

• Wood guarantees excellent thermal insulation;
• Processing lamellas with antiseptic and flame retardant impregnations prior to gluing ensures the strength and durability of the building;
• Deadlines for work. A house made of timber is a kind of designer that can be assembled even with your own hands. Marking all the details and detailed instructions allows you to build a cottage for the month (not taking into account the foundation of the device).

The main disadvantages of laminated veneer lumber that you should pay attention to:

• Availability of falsification on the construction market - carefully study all certificates of conformity and labeling;
• Finnish houses also shrink over time, although not as significant as log buildings. Therefore, finishing work should be carried out after some time - the occurrence of cracks and cracks is not excluded;
• The price of Finnish wood is several times higher than domestic;
• A typical project of a Finnish assembly house cannot be altered according to individual preferences - all the details of the construction assume the standard architecture of the house or cottage;
• Combining multiple materials is difficult. For example, inserts made of stone or brick will be difficult to carefully and reliably fit to the details of the structure.

Conclusion

The beauty and unique aura that natural wood creates will leave few people indifferent. Household of wood not only pleases the eye, but also preserves the mental and physical health of the inhabitants.
