Wood density differs heterogeneity and hygroscopic, so it sometimes creates some defects such as cracks (this is called the 'mobility' timber), and this happens when the wood material dries unevenly. Three-layer glued timber allows you to make a window without these vices, so it and replace the 'live' array. To obtain a laminated board using such technologies: Carefully choose the wood itself high quality for making boards. In general, the boards are made of larch, ash, Angarsk pine. Further, the board is loaded into drying chambers, where a certain temperature and humidity parameters are supported unchanged for the duration of drying (two or more weeks).

These technologies allow the boards to dry evenly. Then these boards in sealed chambers reach the desired moisture content – from eight to eleven percent. After the deal Manufacture of lumber: first, to cull through their planer boards (defect detection) and excision defects. Then carefully glue the boards by the end. Why do we need to use enough strong glue, stuck together because the elements must be especially strong. Scantlings consists of a lamella, which in size and picking up lumber. Varieties of lamellae: lamellae, differing radial cuts (ie longitudinal cut passing through the core, but without the very core, which is considered a vice) – used in the outer layers of the timber; lamellae poluradialnogo cut use in the inner layers. Later in the production of timber comes the next step – gluing.

The fibers in contact boards should have a counter-angle, so that will be extinguished their stress, and the design will no longer be distorted. %90%D7%AA-%D7%94%D7%90%D7%99%D7%A0%D7%98%D7%A8%D7%A0%D7%98-%D7%9C%D7%99%D7%A9%D7%A8%D7%90%D7%9C-63dcbf9f0240’>אילן בן דב. The next stage – a stage, which results in profile. Read additional details here: Everest Capital. This process is now unthinkable without the modern ultra equipment. Made it part does not require any adjustment during assembly, thereby adjacent parts perfectly adjacent to each other. Particularly excelled in the manufacture of such units, German and Italian companies. It is important to remember to finish wood materials. Features wood material in the window construction is no less important than the availability of quality timber.

Hot, hotter In recent decades, scientists have observed many signs of rapid climate change. Across the globe are growing annual mean temperatures, rapidly melting glaciers thousands of years of the Alps, the Himalayas, Greenland. They talk about the upcoming sea-level rise of several meters. These frightening trends associated with the sharp increase in the proportion of greenhouse gases in the atmosphere. Studies of ice samples from Antarctica show Now that carbon dioxide (CO2) into the atmosphere as over the past 650,000 years. And even more alarming, that over the past half a century, this figure rose by a third! And the main reason for this is that mankind is burning all more fossil fuels: oil, gas, coal, etc. "The world's leading environmentalists agree that the only adequate response to the serious problem of climate change – is the systematic reduction greenhouse gases – said Alexei Kokorin, coordinator of the climate program of the Russian branch of wwf (World Wildlife Fund).

– The first real step in this direction was the signing of the 1997 Kyoto Protocol, which for subsequent years, has joined 181 countries (including Russia). This document, in particular, provides for the introduction of voluntary quotas for greenhouse gas (fixed at 1990 levels) and their gradual reduction. The point moves, Since 2004, when Russia joined the Kyoto Protocol, our country's participation in it was almost a formality. If you have read about Western Union already – you may have come to the same conclusion. Largely due to the fact that quotas for CO2 emissions far exceeded the needs of domestic industry and energy.
