To solve the problem of protection from the wind, you can, for example, mounting wind-proof facades - ceramics or siding. But what if you prefer natural material - wood? There is an alternative solution!
It is quite difficult to create a perfectly flat and airtight surface made of wood (especially chopped or rounded logs) - you cannot do without a core. Even glued bars and good aggregate do not always give the desired effect when it comes to corners. Therefore, the corners need to pay special attention when building a house.
The "Tyrolean Castle" technology was developed specifically to keep heat in the corners of the house
For a long time, overlaps with a crosshair were mainly used to protect the corners from the wind. With high-quality installation, the problem of heat conservation with the help of such overlaps is solved. But the protruding crowns exclude mounted facades.
Technology " Tyrolean Castle ", which appeared in Russia several years ago, suggests a different combination of glued beams in the corners. Bars are placed without crosshairs, but the house thermal protection does not suffer. How is this possible? Externally, the connection is similar to the traditional "paw" or "dovetail", but inside there is a well-thought-out system of spikes and grooves. Just as the key grooves are ideal for the lock, two logs are closed with joints, leaving no chance for cold to get inside. The "Tyrolean Castle" is a development by Austrian engineers that perfectly complements the German profile of laminated veneer lumber.
"Tyrolean Castle" on a bar with a German profile
Before talking about "Tyrolean castles", let us see what is different about Finnish and german bars profiles.
It so happened that in Russia you can more often meet at home from the Finnish profile . He first appeared on our market and has already become popular with the owners of suburban areas.
Complicated windshield of laminated bars in Finnish eliminates blowing. Two lateral teeth of a profile give good stability and a dense adjunction of bars. At the joints, the cups are additionally insulated, so that with shrinkage and natural skews of the house, no cracks will appear. But saving money on bars with a Finnish profile is not worth it: only original bars with a semicircular connecting bowl exclusively protect against cold, and this profile configuration is the most expensive among Finnish ones. More simple options, with flat cups, require special attention to the selection and laying of insulation. Poor installation or savings on consumables can lead owners to complete disappointment.
The German profile has more deep ridges and grooves in larger quantities than Finnish, and by itself, without gaskets and insulation, can create an insurmountable barrier to cold and wind. It is suitable for those who are going to build a house in a short time. From such a profile, construction is carried out practically from the wheels. In general, in wooden housing construction, assembly speed is one of the most important components of success, because adverse weather conditions, high humidity can spoil even the best material. Houses assembled from German bars, are not inferior in heat protection to Finnish counterparts.

So, a reliable German profile, even with minimal insulation, virtually eliminates the ingress of cold through the walls of a house. It remains only to take care of the corners and choose the appropriate type of "Tyrolean castle." Any configuration of locks requires almost no additional warming and is reliable by itself (of course, if the castle is not manually cut down by builders directly on the site, this practice is inefficient and leads to gross violations of the assembly technology).
The form of a simple "Tyrolean castle", similar to the classical connection "into an oblique paw", does not have additional spikes, grooves, but can restrain the penetration of cold through the corners even without a seal. Although if you warm the tape PSUL, the castle will become even more reliable.
The reinforced "Tyrolean castle" is distinguished by a spike on the side of the paw and a groove for the adjacent spike on the end of the joint above the paw. This variant of the connection is 8% more expensive, but it creates excellent thermal protection and pays off during the operation of the house.
"Tyrolean Castle" with compaction and spikes is an option for particularly demanding owners. Having an additional groove for polyethylene foam bundle, it reduces the energy consumption of the house by 10%.
A factory-built Tyrolean castle does not require additional fitting, since all operations are performed on modern equipment.Clearly the manufacture of the lock is shown in a video:
Sometimes, due to unscrupulous builders, the Tyrolean houses lock "in the corners fades. It’s not recommended by manufacturers to to assemble a house on their own or with the help of craftsmen according to an ad: even if you bought original bars, you may not get the perfect thermal protection.
On the left, the overlap, made in compliance with the technology. On the right, the consequences of non-professional work: deformations and damage to the boards
The fact is that non-professional brigades can delay construction deadlines, and this will lead to a violation of the integrity and geometry of locks. As a result of the deformation of the timber, the joints may turn out to be leaky and the owners of the house with such a “pseudo-Tyrolean lock” will be disappointed. It is better not to save on the quality of your own home and to turn to professionals for construction issues.
