Alyuminievyiy a profile — the best decision for svetoprozrachnyih designs

In modern building of a design from aluminium acquire the increasing popularity. New forms of architecture force designers and builders to search for the materials differing not only ease and durability, but also having high aesthetic qualities and firmness to all negative effects of environment. All these qualities are answered with the aluminium which durability is estimated in the semicentenial period of a life.

Today it is difficult to present itself many facilitated designs without use of aluminium profiles. It to thefull concerns manufacturing of doors, windows, facades, winter gardens and svetoprozrachnyih roofs. Items from aluminium are successfully applied in interiors of premises - facing of walls and columns, easy frame partitions, the exhibition cases directing profiles for cases-compartments. Modern systems of aluminium profiles supply unique and stylish appearance to structures.

Recently along with foreign designs of profiles the increasing demand is found by domestic aluminium designs. Their richest architectural possibilities allow to create interesting structures which differ high reliability and a long economic life in any climatic zones of Russia. Probably, that fact is not less important also, that they are simple in service. Aluminium designs completely meet high requests modern GOSTov and new SNiPov both on heat - and sound insulation, and on air permeability.

The big spacious premises and a lot of natural light - one of the basic requests of modern architecture. The people who have got tired of small gloomy premises, constraining their individuality, realise now aspiration to visual freedom in space, using new architectural technologies in building. Modern light decisions is use svetoprozrachnyih designs: atriumov, antiaircraft lanterns, transparent roofs, stained-glass windows. The technical decision in building of similar forms with the big flights is the combination of steel and aluminium designs. Steel designs (farms, beams, columns, raskosyi) not only increase prochnostnyie characteristics, but also give to all structure a modern kind in style Hi-Tech. Aluminium profiles, along with their firmness to external effects, have elegance and refinement of forms. For example, in bow-shaped roofs which are used actively by architects for realisation of the ideas, glass application is expensive. In this case polycarbonate can be worthy replacement. This material allows to build designs of difficult forms. As acknowledgement that is served by many objects of new office buildings, hotels, banks, industrial buildings, cottages and inhabited complexes. In them metal and polycarbonate are used.

One more dignity of aluminium — its harmlessness and ecological compatibility. Therefore use of designs from an aluminium profile in inhabited and civil buildings does not cause any counteractions.

If to speak about design features of a material, its high durability at low specific weight allows to create the glazed surfaces of very big sizes (winter gardens, for example), any forms and with various methods of opening. Frames and shutters thus will be thin, "air", not begin to interfere with natural illumination.

Those who believe, that at aluminium poor colour scale, are mistaken. There are two technologies of colouring: galvanic and drawing of powder cover. At use galvaniki on a surface the colour transparent film is formed, natural metal shine therefore is saved: kinds «under gold», «under bronze», etc. Powder cover does not require some toxic solvents, and "is baked" at a heat. The colour scale of powders includes some tens colours.

Aluminium, as well as all metals, has high heat conductivity which like would do its unsuitable for a thermal protection. However manufacturers have found antidote — the window frame is made of two polovinok (external and internal) between which keep within teploizoliruyuschie the laths named the thermobridge or a thermoinsert. A thickness of inserts — from 18 to 34 mm, a material - the polyamide reinforced by fiber glass or politermid. The profile with the thermobridge is called as "warm" and can quite be used for manufacturing of windows and balcony doors. The profile "cold" (without the thermobridge) suits only not heated verandahs on a summer residence and for ostekleniya balconies and loggias.
Thanks to that structure of window aluminium profiles same as at PVC, that is has some chambers (2-3 and more) divided by partitions, their characteristics differ high technical indicators. It first of all concerns heat-shielding properties which are especially important at low (to-40°S) temperature of outside air, and also shumozaschityi which is lowered on 38-40 dB, that allows to apply these designs in windows of any residential buildings at the most noisy highways. On enough high level and protection against a dust and a moisture.

Because of dearness of metal cost of windows from an aluminium profile above, than plastic, but more low, than the qualitative wooden. As numerous researches and practice of operation of any profile, including aluminium show, the thermal protection in many respects depends on quality of a profile and, first of all, is defined by quantity of chambers. For our climate profiles with three-five chambers are optimum. The important indicator also is the number of things in common of a frame and shutters - them there should be not less than three-four. A total thickness of a profile not less than 55 mm.

Not less important element svetoprozrachnoy window designs — a double-glazed window consisting of two glasses, connected among themselves on perimetre speysernoy a tight framework. More often in a package there is the usual air only dried that in a cold season on an inside there was no condensate. For the same purpose in a double-glazed window place silikagel — a powder, capable it is good to involve in itself water steams. Sometimes a double-glazed window fill in not with usual air, and inert gas argon that improves zvuko - and teploizolyatsionnyie properties.

The optimal variant for modern windows — a two-chamber double-glazed window which answers climatic conditions of an average strip of Russia. Parametre defining for a double-glazed window on which its isolating properties — depend a thickness. It is defined by width speysernoy frameworks and makes usually (for a single-chamber package) 20-24 mm.

The last years at many international exhibitions manufacturers of glass began to offer builders new kinds of glass with the lowered factor of thermal transfer — K-glass. Its main feature — the raised reflecting effect. Later working out — E-has flown down, at which reflecting ability still above.

These new kinds of glass inserted into aluminium profiles, create real possibility for better and reliable protection of buildings and structures from teplopoter.Victor STRASHNOV Source: "the Building Season" #17 (2003)
