House 10 for 12 two-story project. Plan of a one-story house: options for finished projects with photo examples
Due to 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 bewitching and unique microclimate. The Finnish beam is popular among private developers due to its excellent technical characteristics and guaranteed quality.
What is the difference between glued timber of Finnish production from domestic analogues? When starting to build a house or a country cottage, it is extremely important to choose the right material. Consider the production technology and structural features of the Finnish beam, so that you can make a reasonable and balanced choice.
Production Technology and Profiling
Since the construction of houses made of wood 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 the shortcomings of wood, which, by the way, are not so many.
Technology for the production of glued beams
One of the significant drawbacks of conventional logs is the instability of the geometry. The material expands under the influence of moisture and cracks and warps with sudden changes in temperature.
Advanced technologies for the production of glued structures from wood, which were developed relatively recently, almost completely eliminate the disadvantages of wooden lamellas.
Profiled timber Finnish profile is 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 ensures stability of the lamella geometry. The beam does not deform and does not crack under the influence of adverse weather conditions;
- Low moisture content of the material (not more than twelve percent) ensures minimal shrinkage of the walls 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 humidity of the lamellas are guaranteed;
- After calibrating the boards and eliminating the defects of the wood, the lamellas are spliced \u200b\u200band ground. This treatment allows you to achieve the perfect geometry of the bars;
- Bonding lamellas is carried out under pressure. Manufacturers from Finland use only environmentally friendly materials as adhesives, which do not affect the basic technical characteristics of wood. Finnish laminated veneer lumber has the ability to "breathe", which creates a unique comfortable microclimate in the room.
Important. Strength and durability of the material also gives the direction of the fibers of glued lamellas.
The cut fibers 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 bars are profiled and trimmed with high accuracy, assembly is easy to do with your own hands. The spike-groove system allows you to connect structural elements without gaps and distortions;
- Each part 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 as soon as possible.
Projects from Finnish glued beams are well-deserved 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 castle connection of the lamellas, so the crowns of the bars are tightly and securely fastened.
There are two common types of profiles:
- German profile - equipped with many ridge (sheet pile) joints;
- Finnish beam profile - distinguished by crowned cups for lamella connection.
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 connection remains unchanged - the castle longitudinal connection eliminates lateral shear of the material and eliminates cracks and gaps during assembly.
Main features of timber from Finland
Finnish timber is an elite building material, as 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 the timber from Finland?
- The arcs of annual rings of glued boards are directed toward the center, and the core is facing out. This arrangement of wood fibers guarantees increased strength and durability by reducing internal stress in the timber; (See also article.)
- Different species of conifers do not mix, which guarantees a beautiful and uniform tone;
- Bonding strength is ensured by vertical splicing after four to six meters, but not more than three meters. As can be seen in the photo, this bonding technology guarantees a great appearance and an almost imperceptible seam;
- According to Finnish technology, only wide slats are used. This is due to the fact that the glue base impregnates the wood with one and a half to two centimeters. Therefore, thin lamellas are almost completely impregnated with glue and lose their ability to “breathe”. Finnish timber 200 millimeters thick is made from three spliced \u200b\u200blamellas with adhesive impregnation of not 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 the Finnish beam in terms of technical and aesthetic characteristics is almost identical to the analogue, but the cost of such material is much lower.
Tip. By acquiring construction material from a tree, give preference to a bar from winter wood.
It is drier and more durable.
A distinctive feature of winter wood is a lighter coloration of the ends and the absence of fibrousity on the longitudinal cuts.
Experts advise checking the material in the following way.
Put iodine on a section of the beam - if the spot turns blue - it means a lot of starch in the tree, and this is a distinctive feature of the "winter" lumber.
Advantages and disadvantages of glued beams
Since the price of this building material is quite high, we will dwell on its main advantages and disadvantages. Are the advertising characteristics fair and is it worth overpaying for guaranteed foreign quality? After all, there are a lot of offers from domestic manufacturers.
The "pluses" include the following characteristics:
- High resistance to deformation due to the absence of internal stress. The construction will retain its shape and size and does not deform over time;
- Optimum humidity eliminates long-term shrinkage of the building.
Tip. But glued beams are wood, so minimal shrinkage of the house still occurs over time.
Therefore, it is better to start internal finishing work a few months after the construction of the house.
- Wood guarantees excellent thermal insulation;
- Processing lamellas with antiseptic and flame retardant impregnations before gluing guarantees the strength and durability of the building;
- Deadlines for the work. A designer that can be assembled even with your own hands. Marking all parts and detailed instructions allows you to build a cottage in a month (not considering the foundation device).
In the Russian market of wooden housing for a long time, Finnish glued beams were very popular. It is known that glued beams began to be produced in Finland about 25 years ago. The technological process for the production of timber has been constantly improved: new adhesive compositions were selected, methods for orienting the lamellas of the timber, the thickness of the workpieces, etc. As a result, we got very high quality material - Finnish glued beams. Glued from sorted and specially selected lamellas, the Finnish three-lamellar glued beam combines environmental cleanliness with high strength and durability.
Why is the Finnish beam so popular?
1. For the production of timber using wood special cut.
This saw cut in the center of the log, grabbing or removing the core, resulting in a radial cut of the tree, which is least prone to warping. As a rule, a tonometer (trunks of small diameter) or the top of the tree is used.
A feature of glued beams using this type of sawing is the orientation of the external lamellas when gluing the core side out. This technology avoids significant cracks on the outside of the beam during operation.
2. Lumber of large thickness.
In the production of Finnish timber, lumber of greater thickness is used - 75 mm versus 50 mm for Russian manufacturers. Art Holtz purchases thicker lumber from an Austrian company that successfully harvests timber in the Leningrad, Arkhangelsk regions and Karelia.
3. Health care.
Like Finnish companies, we were the first in Russia to use Purbond polyurethane adhesive, which is harmless to health, due to the absence of formaldehyde and other components hazardous to humans in the manufacture of glued beams.
Art Holtz can offer you a house from a Finnish beam of high quality, which is fully consistent with the technology of Finnish housing construction.
The price of the Finnish beam slaughtered for the project
The price of a house kit consists of the cost of external walls, internal partitions, glued beams, Mauerlat and power roof structures, which were slaughtered for the project.
