The house made of logs a lot of merit. Wood - a living material. And even after being cut down, it continues to "breathe", radiating energy health. In the log cabins maintained by natural ventilation and in a house breathe freely and easily. In this house made of logs will be much warmer than the stone walls of the same thickness. Wood can generate heat evenly - a measure of giving it, so in this house saved optimum microclimate and temperature.

Unquestionable advantage of logs - smooth rounded shape, which allows for the construction of houses with high precision and density of the crown and corner joints. The shaped beam to a lesser extent subjected to strain aging. The technology works with "Cylindering" avoids obligatory laborious fitting during construction.

An important factor for choosing logs - the unique beauty of the tree stored in its original form. Natural texture patterns fascinate, please the eye and give the interior of wooden houses a wonderful elegance.

Most often in the construction of wooden houses used coniferous trees. The most common - is spruce and pine. Wood has a number of properties that distinguish it from other building materials.

Wood - a material created by nature itself, is absolutely safe for health, and also supports oxygen balance and optimum humidity. Wood has with nothing comparable beauty, radiates heat, and finally, this material can be reused "revive".

Wood - it is environmentally unlike many building materials that can cause an allergic reaction, it has no harmful effects on the human body. Wood is easy to work that provides a wide variety of building materials.

PINE relates to softwood. Live 400-600 years and into adulthood (120-150 years) reaches a height of 30-40 meters. Its trunk is straight, it is easy to saw and planing. Wood has a sound part of the trunk, which is almost the same color from yellowish-white wide sapwood. When drying and storing core darkens and takes brownish-red tint. Early wood lighter late wood. Knots are located in the core at the ends of the annual addition of growth. Shoots are directed upwards at an acute angle to the bore axis, so sectional view (on timber) are oval in shape. Resinous large and numerous. The wood is soft, easy to process, not crack during drying. Thanks to its beautiful colors and clearly defined structure, it is widely used not only in the construction of houses, but also in the production of wood products in the manufacture of artistic carvings and handicrafts turning.

Depending on the degree gummosity are two varieties of pine - tar heavily tarred and dry, containing the minimum amount of resin. Tar may lie at the bottom of the river for decades. Therefore, use it where very damp: the construction of piers, wharves, bridges, parts of wooden ships. Three or four crown of tar carpenters went to lay in the wooden house first. Dry is used to make products not capable of withstanding heavy loads. It is easy to cut and planed, lends itself well to be etched and stained.

FIR prevalence is second only to pine. She lives up to 300 years and into adulthood (120-150 years) sometimes reaches a height of 50 meters. Trunk of her round and straight. Wood - light, soft, without a kernel, uniformly white with a slightly golden hue, for a long time able to retain the natural color. Late wood has a narrow view of a light-brown band, which passes in early stages. Knots on spruce located whorled, almost at right angles to the axis of the barrel; due to this they seem tangential sectional round. Wood has a small resinous, it is resistant to cracking. Spruce wood is difficult to process due to the high hardness of knots, but in some areas, huts were built entirely of spruce. In ancient times the peoples of Western Europe was considered the patroness of spruce animals, birds and plants. Ate good spirit defended human life from every adversity. Spruce was revered as a symbol of eternal life and youth. The ancient Germans, trying to appease the mighty spirit of the forest, living in sacred fir trees, their branches hung up on all sorts of jewelry. Later, when it was lost magical significance rite continued to dress the Christmas tree tradition to the New Year.

Lift off the ground ripe cone and consider carefully. The flakes are disposed so that each lamella overlaps the two lower, in turn, its two upper cover. When the bump is hanging on a branch, rainwater on it, as on shingle roof or Ploughshare flows down. Involuntarily assumption - not at any bumps learned Russian carpenters cover shingles glavks churches, shingles and shingles - rooftops?

Scaly bumps in roof safe and hide under each flake corns are not afraid of even heavy rains. Before the rain, when moist air, the flakes are pressed together more tightly, and in dry weather, on the contrary, open, and mature seeds winged parachutes rotating slowly and carefully lowered down.

To have an idea of spruce wood, widely used in household and industry, cut dry twig and carefully consider all three cuts. Spruce wood is yellowish white, sometimes with a slight pinkish tinge. On all cuts are clearly visible annual layers. Early, spring, layers - lighter, porous and wide, late, summer - dark brown, thick and narrow. Medullary rays are numerous, but so narrow that the naked eye almost invisible. Spruce wood is moderately strong and soft, light and moderately shrinks. She is good in the radial cracks. and tangential directions.

Fir wood is often confused with pine. At first glance, one timber is not much different from the other, although they have different physical and mechanical properties. We must remember that the pinewood much lighter and softer pine on it more frequently overgrown with small knots with a characteristic iridescent luster. And yet - spruce wood in most cases lighter pine.

In many areas of Russian spruce is widely used in construction.
