Wooden House in favor

Natalia Tyannikova According to recent statistics, more than 40% market share of low-rise residential buildings are buildings constructed out of wood. Also in the top three - construction of laminated veneer lumber. Built the house from a tree, you can not only realize the most daring architectural dreams, but also to create an environmentally comfortable habitat. This home was created by nature, so inside the person feels more secure, healthy and happy. Russia and the other course, Russia - a country with ancient traditions of wooden architecture. But for the holiday season and for the permanent wooden houses are built on almost all continents of the globe. For example, Americans annually buy 500,000 such buildings in Japan, erecting more than 300 000 houses per year, while in Europe - 100 000. In the Scandinavian countries, almost 90% of all houses made of wood. Yeah sure, if only in one Finnish wooden houses built annually 4000 for permanent residence and not less than 5000 homes for a country holiday. Stone and wood - who wins? Application of new technologies revolutionized wood in a modern house building. Now the wooden structures are not simply inferior stone or brick, and in many positions and surpass them. Appearance, ecology, ie the ability of wood to "breathe" (to maintain a constant exchange of air in the room and create a favorable microclimate), relatively high speed of erection of structures - these are the main advantages. Wooden houses can be called a strong and durable, and, moreover, and cost-effective, because for them is not required to build a strong foundation. Coefficient of thermal conductivity of wood is 0.18 W / sq. mxgrad. that is 4 times smaller than the thermal conductivity of masonry - 0,76 W / sq. mxgrad. This makes it possible to create a warm home with a wall thickness much smaller than in a brick building. It is worth noting that under the terms of comfort and health standards in accordance with SNIP 11/03/1979 for the north-western regions of Russia the required value of the coefficient of heat transfer resistance R = 3,49 sq. mxgrad. / watt. And the walls of laminated veneer lumber fully comply with this requirement. Pluses of laminated veneer lumber traditional materials - timber or solid timber - have some drawbacks. First of all, the manufacturer of log cabins involves highly skilled carpenters. The process is lengthy, time-consuming and requires an individual approach to handling the material. The calculation must be taken and significant sediment home construction. The logs have a moisture content, usually more than 30%. When drying them in the wooden house within one to two years, the shrinkage of the walls is 10-20 cm on the floor. This means that the finishing work to be delayed for a considerable period of time. Tendency to cracking and warping during use, exposure to weathering and biological factors (mold, insect infestation) - is the bane of all houses of logs and solid timber. In recent years increasingly used a more advanced manufacturing techniques of wooden houses, devoid of the above disadvantages. In accordance with her traditional log becomes a raw material for production of high-tech and better building materials - plywood. Modern corrugated laminated veneer lumber is manufactured as follows: - timber sawn into boards (slats) - the board is dried in drying chambers to 8-10% moisture - boards glued together a special two-cleaner glue under pressure (using a press) - of dry wood package on the four-machine profiled wall beams or joists of the special form - ready to board "the end" (trimmed) for the project and zapilivaetsya "in a cup" or "paw" on high-precision milling equipment - each item is labeled, as a result What is going home, as a designer, and does not require a long carpenter's work. Thanks to modern technology bonding may be used on glued wood in virtually all structural parts of wooden houses (for wall beams, trusses, floor beams, etc.). The use of laminated wood economically justified, and has undoubted advantages in comparison with the whole. High surface quality. It is due to the fact that before the gluing of wood cut out swirls and defects, billets are selected by color, texture. Therefore, products made of laminated wood differ flawless appearance. The stability of geometric parameters. In contrast to the solid, laminated wood retains its shape and size over time. She does not shrink, twist and bend. This is explained by the lack of laminated wood of internal stresses, as well as the fact that she is made of pre-dried material. Strength. Constructions made of laminated wood are 50-70% higher strength compared with the whole. High thermal performance of wooden houses. This factor greatly reduces the cost of acquisition and operation of expensive heating equipment, transportation and storage of fuel. The cost of heating a house built of laminated veneer lumber, will be 10-12 times less compared with brick. How we build it? Terms of home construction from laminated veneer lumber, of course, far less than solid. Since all parts are made with high accuracy at the factory at a constant temperature and humidity, the assembly house construction is easy and fast installation on a finished basement does not exceed 5-6 weeks. In addition, the House of laminated veneer lumber does not require time for shrinkage (shrinkage of the house is only 0,5%). Dates of the finishing work is significantly reduced, and start building the cottage at any time of year. A separate question - warming houses. Horizontal joints between the logs warm and condense complex than between bars. Profiled glued timber tightly connected to the assembly, so no need to put insulation in the slots between them. In addition, the profile bars are calculated so that rainwater does not fall between them. This prevents the design from rotting. There is yet another technological feature. When gluing in the timber selected fins mutually opposite direction of wood fibers (annual rings). Due to this increased strength is achieved. Even with a good fit separate log blockhouse, the walls in this house are still quite rough surface, which considerably complicates the finish. At the same time the surface of laminated veneer lumber, made in accordance with all technological requirements, level and smooth. Collected from such a timber wall look monolithic. Exterior finish it virtually unnecessary. But due to lack of cost is significantly reduced finishing cost of the project. At first glance, it is difficult to trace the dependence of the construction boom the last five years, the popularity of the simple, albeit high-tech laminated veneer lumber. However, the position of this material in the construction market strengthened, and homeowners who are satisfied with your purchase, it becomes more and more.
