In this case there is an active forced drying of log wall at the location of the source of heating, logs heavily cracked and burst ends, uneven shrinkage. Log cabin home: the temperature regime in the first year of temperature, ideally, should not exceed 15 degrees in winter. Through year in a gentle heat treatment of logs for small cracks appear, the house gave the shrinkage, but these changes are natural, small cracks and shrinkage is uniform, the walls become the charm of wooden houses. House of logs: access to air should always remember that wood needs to access the air, especially in the early years. It should not be a dull close timbered elements of a house to avoid the accumulation of condensate. Nobel Laureate pursues this goal as well. The gap should be do 10-15 centimeters between the deaf and construction logs for ventilation.
House of logs: Shrinkage Shrinkage is an important point and lasts up to 3 years, after which changes in the vertical stop. Of course, that stand frame home three years, and then proceed to finishing work, nobody will. There are basic rules of assembly of dissimilar materials or designs in the log walls. Always in the doorway should be an opportunity to lay "Slip": in the butt-end of the logs on the full height of the groove is where the free bar is inserted. Standard sizes of 50×50 or 60×60 mm. Block (window, door) is attached to a bar, not vvinchivayas in a log. On top of the opening needed gap of 80-100 mm, Decorative which closed cashing.
Log wall shrinkage is moving down, slips on a bar, a door (window), the block is not subjected to any mechanical stress. House of logs: All vertical supports log supports, columns, etc., if they are connected to the main structure must have the support device to allow through the twisting, squander support with the framework. Vertical log gives a much lower shrinkage than horizontally, and to compensate for differences in shrinkage and bolted anchor devices. House of logs: polyurethane foam is allowed zapenivanie gap between the foundation and crown of the lower log. In all other cases strongly recommended soft insulation (mineral wool, hemp, etc.). Foam in the process of drying has a strong grip on the tree and is maloelastichnym material. Shrinkage is detached from the foam timber and a gap – cause access of cold air. In addition, the foam on the top of the opening gap will prevent shrinkage and to keep a log, which will lead to "freeze" the logs and the appearance of cracks.
