The technology of manufacturing a hand made house
For walling production we use pine wood logs 32 cm in diameter and up to 12.5 m long. Pine is a wonderful thermo isolating material which meet the requirements for residing in all seasons. Logs are sawn to make a rectangular bar with the standard thickness 160mm or 200 mm. The height (width) of every bar is individual ranging 250-450 mm. The natural narrowing of a log (from the bottom to the top) is used in timber processing.
The production technology allows the difference of 1cm in height per every meter of length. We use two kinds of bars: with the oval facet and with the straight one taken at the angle of 45 degrees. Sawn goods up are dried up to humidity 18-20% and treated by antiseptics. First of all, the timber is kept under shades with enough spacing provided between bars for natural aeration and drying.
Then, before entering a construction site, as required by production technology, a bar is placed into a drying chamber. Processed like this a bar gives less crackles and the wood saves its healthy properties almost fully.
For wall manufacturing the technology of angular joints of the type “Norwegian Cross” is used which is widely spread in Norway for several centuries. Norwegian Cross is known to provide a very good quality for angular connection between the walls. When crossed like this, bars form self-locking joints in a corner which provide proper rigidity of the whole construction. Besides, for strengthening of walls and stiffness of the construction birch pins(nagels) are used for fixing wall bars.
Every wall bar has a natural narrowing that is why in a hand made house every corner joining is performed individually by hands. For this special tools produced in Germany or Norway is used. This enables accuracy and precision of joints. We ensure a high quality of the houses produced (no cracks in angular joints sites). In the middle, along each log a longitudinal anti deformational cut is done which provides control of longitudinal cracks parallel to walls. This cut is the optimum for a log house.
Then this cut is covered by the groove of the overlying log. To adjust logs special carpenter’s tool is used which drawing the line repeats the profile of an underlying log on the surface of the next one. Then by means of the electric saw, a special axe and tesls the necessary groove gets out. As a result an ideal connection of logs is reached which provides a proper density even if humidity of wood is lowered. A forced rigidity of a construction in an assembly contributes to the decrease of settling of the house.
Due to traditional Norwegian elements of rafters systems all design of a roof has a unique appearance outside and high original ceilings inside a house. Elements rafters systems are made of lengthy fir-tree logs (up to 14 meters) planned manually the diameter of which after processing makes 270-350 mm depending on a size of the construction.
The frame work of each building (including a design of a roof) is assembled in an industrial premise of the enterprise. After this all walling bars and roofing elements are enumerated.
Then a house is dissembled, walls are planned with a manual plane which provides a higher degree of smoothness and accuracy.
Then a construction is gathered into packs, fixed with a packing tape and sent to a buyer. As far as the house is manufactured out of well processed material (walls are finished manually) there is no need for additional finishing it is available for residing immediately after its erection. The natural structure of wood creates a special design of walls. The house can be immediately painted from outside so the dried up wood with humidity 18-20% is used for manufacturing a house. This will additionally protect the wood from the penetration of a moisture.
Massive log walls guarantee warmth and comfort, keeping the house warm in winter and cool in summer.
Many manufacturers produce hundreds of complete house sets every year on special lines - conveyors with mechanisms thoughtlessly performing the work. Having an opportunity to compare, people would always prefer a good hand-worked house to the house made serially. Century old pines growing in our woods make a wonderful construction material. A hand worked cabin manufactured with every bar adjusting the profile of the following one and keeping its own individuality not turning into just a "pencil" can stand for centuries. One can order houses which will meet requirements and opportunities of every client.
A Standard complete set of a hand made wooden house:
· walls made out of a pine bar (laft), thickness of a bar 160mm, 200mm, 220mm, 240mm;
· rafters for a roof 200x50, 250x50, 200x100;
· roofing round beams, diameter 30-40 cm.
· additional pine beams for roofing rafters 50mmx50mm;
· birch taps (pins,nagel) for a fastening wall beams.
In addition decorated columns for terraces can be made, roofing boards.
