Glazings: what's about?

Energy saving, environmental protection, land and climate are great social and political issues worldwide. In this context the capacity of thermal insulation of buildings is a current topic of general interest. Halting the loss of energy inside the building exterior has favorable consequences on thermal comfort and enables reduction in the amount of fuel used for energy production, causing reduction of carbon dioxide released into the atmosphere. Insulating windows have appeared in more than three decades ago, production technologies are continuously perfecting and gaining ground on the market. Since 1980 the company Pilkington, England - world-renowned company producing glass technology inventor "float" - launched glass type "Low-E" (low emisivity) with heat transfer coefficient Ug = 1,4 W / mpK ˚ C . This high performance glass has a surface covered with an extremely thin film of noble metal, applied during the production process at a temperature of 600 ˚ C. Layer is almost invisible, positioned inside the window to protect it from climatic influences and potential mechanical damage. Special film that covers this type of glass reduces heat loss by 90% - as is lost through normal glass - only 10%. Glass with low emissivity (Low-E) significantly reduce energy loss, a solution to the western demands.

What is insulating glass?

Is a set of two glass sheets, between which there is an insulating layer of gas that can be air or inert gas, quality performance is different depending on the type of glass used, thickness of oil, gas environment used, achieving perfect seal the space between the glass was Various types of insulating glass performance evidenced by the heat transfer coefficient - Ug - measured in W / mpK ˚ C As low as the Ug will provide comfort to increase by 4 mm thick plain glass Ug = 5.4 W / mpK ˚, clear insulating glass with the air heat transfer coefficient Ug = 2,8 W / mpK ˚ and an insulating glass with Low-E (obtained by deposition on float glass, a layer of noble metal, silver, microscopic size, imperceptible to the human eye, the role of reducing heat loss) is air Ug = 1.4 W / mpK ˚. If replacing the air with a layer of gas with low heat conduction coefficient (argon, krypton, xenon, etc..), We can lower heat transfer coefficients. For example, if the cavity introduce Low-E insulating glass with argon (colorless, odorless, non-toxic) or krypton (noble gas, colorless, odorless and tasteless) transfer coefficient is 1.0 W 1.1 respectively / mpK ˚. Xenon (odorless and colorless gas, is to liquefy - 108 ˚ C is a colorless liquid, in solid state is in the form of a white mass) heat transfer coefficient can be decreased below 1W/mpK geamuliu ˚. Using quality glass termizolator pay less money for heat. Worth to look at those mentioned and see the difference in annual fuel consumption for a conventional square meter heated surface to use different types of glass. Using Low-E glass instead of ordinary glass reduces heating fuel needs 19 liters of oil, or 22 cubic meters of gas annually report on each square of glass!

Much of the glass surface corresponding opening (70-80%) and as such must be considered when analyzing thermal and acoustic insulation. Heat loss through windows Romanian homes were not subject to special interests and the sound insulation is not remembered, housing rehabilitation program and the improvement of thermal comfort is a new way of addressing the issues mentioned. Nr.29/2000 Government Ordinance, now the law, the certificate provides energy getting any new construction, and construction of entering the rehabilitation program. About 40% of Western studies on energy saving building energetics refers to the problem. It aims to build the best possible price, using appropriate materials and then building once built, to ensure energy needs at lowest cost. Consider the possibilities that we make available modern joinery firms producing insulating glass with such performance. You can convince the utility of installing at home with PVC joinery, Low-E glass and argon. For further details and analysis of the optimum quality glass in light of the situation of your home you should contact the firm for advice given by specialists of your choice.
