In our country - the state forests - the tree at all times was the most available building material.
Laminated veneer lumber still enjoys deserved popularity (10 to 20% of home buyers initially prefer the wood, not brick or monolith) because it has a number of very attractive characteristics.
First, the tree has a low thermal conductivity coefficient. This means that a wooden house will heat up more quickly and cools down much slower. So the wall of wood, you can do much thinner brick. This leads to a reduction of the weight of the structure, it is possible to put on a light Foundation that is almost a third cheaper construction compared to brick. But not in the same economy business: breathing properties of wood allow at any time of the year to maintain a comfortable indoor climate; therefore, by the way, most of the wooden buildings refuse from interior.
Second, the qualitative treatment of the wood itself is very aesthetic: the interior of a wooden house with no additional finishing is not only environmentally friendly but also beautiful.
However, the natural material has significant drawbacks. The main ones are - change of the geometrical dimensions with changes in moisture (swells with moisture, shrinks and is deformed at low) and the susceptibility to decay and microorganisms carpenter. These shortcomings quite long ago learned to eliminate due to the "artificial" laminated wood and the processing of special compounds.
The technology of creating building materials out of wood, does not shrink and is resistant to decay has long been known: glulam distributed in our market (a patent for connecting wooden slats by means of glue obtained in 1890) with the 90-ies of the last century. And last quarter-century has provided an opportunity to ensure its reliability for many years are on the sites of our compatriots built garden homes and winterized cottages of laminated veneer lumber.
But progress does not stand still. Appear all new and new building materials, which are based on natural wood - with new properties and improved consumer qualities. To those - occupying their niches in the construction market today - can be attributed to the CLT panel, turned, glued laminated timber, wood brick, wood "sandwiches". Relatively new technologies (still developing) includes the manufacture of insulated timber of laminated wood with cork oak. Despite the fact that wood is a good insulator, to meet the modern standards the thickness of the wood walls must be pretty big. At least, is much wider than the frame construction, where the insulation is used more effective materials. That had to choose between sustainability and aesthetics of natural wood - and the warmth of a "sandwich".
Insulated profiled beam (termobrus) and created as a compromise for construction in the Northern regions. It looks no different from the "real" wooden counterparts, but are significantly greater than their thermal insulation properties. This is achieved by the fact that the core of the timber is part of lamellas are glued sheets of high quality thermal insulation material - polystyrene, polyurethane, tube. Or the remaining cavities are filled with cellulose wool. This timber is much warmer: the heat-transfer resistance of termobrus thickness of only 16 cm is equal to the resistance of the glued laminated timber in 49 cm, and normal is 60. And the same "warmth" masonry must be with a thickness of 2.6 meters! In this case equal to the thickness of the insulated rail is approximately twice lighter than usual, which allows for a lightweight Foundation to build country houses in which it is possible to live year-round.
In the end we have home heating is comparable with the frame, but with better environmental performance, as to turn it into a "flask", sealed insulating insulation sandwich panels from the inside heated space (to avoid dampness and subsequent freezing), is not necessary. And if the glued timber quality insulation - with the environment at home, everything is in order.
We offer you to look projects houses from glued beams.
