Glued Laminated Timber

In the modern market of building houses from glued beams occupy a high enough position. This can be explained only one way. In an era of globalization tend to use safe, environmentally-friendly, and best of all natural things. And such a building material as a laminated board is fully fit these requirements. Why exactly glued laminated wood? Glued laminated timber – is a high-tech, with excellent physico-chemical properties of construction material, retaining all the best qualities of wood.

Wooden houses from this material are easy to mount, as are made with great geometric accuracy. Log houses have excellent heat and sound insulation characteristics are known for their longevity. Each organization dedicated to manufacture laminated veneer lumber has its own production technology. There are two types of laminated veneer lumber – is profiled and structural. As a rule, shaped laminated veneer lumber, used for the construction of walls of wooden houses. A structural beam convenient for the formation of load-bearing structures – beams, trusses and similar engineering elements.

In untreated wood in the form of conventional whole-profiled logs there are many significant gaps, and most important of them – it is a long term drying out. That's why the construction of wooden houses some difficulties, one of them – the shrinkage of the house up to 15%. In this case, construction slows down, because after mounting, about a year to wait until the house "sit", and only then start finishing works, installation of windows and doors. Typically, the construction of timber processed by standard methods appears cracking. At home of laminated veneer lumber sit down, but not more than 1%, thus reducing the time construction of the house. The secret of high strength of resistance to various kinds of impact lies in the design, which has a laminated veneer lumber and method of its manufacture. Construction of wooden houses is becoming more fans. According to statistics, at the peak of their popularity is laminated board, adding to the existing volume of production is still 10%.

Commercial Director

"Production of European-style – is not only the latest equipment and technology but also multi-tiered system of quality control – says Leo Minullin, Commercial Director, td propleks (the exclusive supplier of pvc profiles produced in Russia in the Austrian technologies). – We are working on the Austrian extrusion equipment for the compounding of the raw mix, developed by experts of this country for Russian conditions. Composition of components adapted to our climatic conditions, in particular, to a frosty winters. Moreover, additives (pigments, stabilizers, plasticizers, etc.) are delivered to us directly from Austria ". Each batch of raw material input is hard to control quality control laboratory at the plant propleks.

Regularly carried out tests on samples of products according to parameters such as strength, heat resistance, color surface. A special climate control simulated weather effects in real-world conditions. Samples of the profile is subjected to several tens of cycles of wetting and exposure to ultraviolet light, and then examined for signs of damage, changes in color and strength characteristics. If the samples did not pass at least one test, reject the entire batch of profiles, as manufacturing technology is adjusted to eliminate the violations. Such a quality control system to meet most severe European standards, ensure that the profile was released at a factory in Moscow or Siberia, is no different from fellow extruded somewhere Bavaria or the outskirts of Vienna. However, Russian consumers are often unaware that the "pedigree" of pvc profile and its quality – this is not the only conditions for long life plastic window.
