How are Naturi timber houses built?
Recently I came across an interesting technology for building houses called Naturi. At first I thought that the technology was French, but it turned out that it was developed and applied by a company from Russian Kirov. Well, the region is more than wooded, it has long been famous for its log cabins, so you can study the technology in more detail, I thought.
The first house using this technology was built in 2000 in the Austrian part of the Alps (the owner of the house is Georg Ganaus).
The main feature of the technology is construction from a "vertical" bar. The creators claim that since the trees grow in this direction, then the house will become more stable and will not shrink.
The shape factor of the Naturi bar seemed interesting to me. Thanks to the grooves, heat loss should really be kept to a minimum. In any case, only a thermal imager will give a true picture.
And in this photo there is a cut of a bar made using this technology:
Due to the fact that the beams are joined groove-in-groove in 3 months, builders erect a house with an area of up to 200 square meters. A speed comparable only to the speed of construction using frame-panel (Canadian) technology.
Here is another interesting shot - the upper part of the window opening, bottom view:
Not being a specialist in wooden housing construction, I cannot unequivocally judge how reliable this technology is. One side, grooves remove the main cause of heat loss in log cabins - cracks. On the other hand, the vertical orientation of the logs is very confusing.
