Energy Glass

Today more than ever all efforts are focused on saving energy for both economic and environmental reasons. The best economical and environmentally friendly solution is to use energy glass. The need to improve the energy efficiency of buildings has led the global glass industry in the construction of modern dual energy solar control glass (Low-e, Solar Control). The panes are able to improve the thermal insulation compared with ordinary double by about 200% and about 400% compared with ordinary single.

The energy glass is a transparent glass, which has microscopic metallic oxide coating on one side. This coating prevents heat transfer from the interior to the outside and vice versa. It has similar appearance with a common glass but reduces the incoming radiation to quantitative up to 75%. Using energy glass achieve cost reduction in cooling in the summer, after keeping the heat out of the house, and apodotikoteri insulation in winter after holding the heat inside the house.

This coating reflects energy of infrared radiation, thus retained by the radiant heat from the same side of the glass from which, while allowing passage of visible light.

This leads to what efficient glass because the thermal radiation from indoor winter reflected back inside, while the infrared heat radiation from the sun during the summer reflected on the outside of the building, keeping the cooler inside. Such glass is ideal for climates with high sunlight (such as our country), and moderates the solar heat entering the space.
The acquisition cost (or replace existing, either for primary fitting) a proper energy glazing for a typical apartment, no more than 1200-1700 euro. According to studies, the acquisition cost difference between energy windows and ordinary double amortized in about a year. This means that from the second year onwards and throughout the life of the building, energy glazing practically contribute to oikgeneiako budget. We should also mention that energy glazing last generation, practically no life limit, while not absolutely require no special maintenance beyond the typical cleaning like all ordinary glass.Finally syndiazomenoi (with very little extra cost) with safety glass or fire or ichomonotikous ensure buildings further important advantages.

 

WHY MUST USE Insulated GLASS (LOW-E)

The windows are responsible for most of the heat loss in a building. The heat loss of a building caused by 20% on the floor, 25% on the walls, the roof 20% and 35% to parathyra.Diethneis studies have shown that if instead of simple double glazing (U = 2,9W / m²K) energy use double glazed with Ar (U = 1,1W / m²K) can achieve up to 62% reduction in the U-Value. So in winter we can reduce the heat lost from the glass than 62%, and in summer to reduce up to 62% of heat entering the difference in temperature. Furthermore, we can achieve a 65% reduction of the solar factor Solar factor (SF) i.e. the heat which enters said solar radiation (2/3 of total heat), since the solar factor of the double glazing is plain SF = 75% while the energy and reflective double glazing with Ar is SF = 10%. Follows ie, total summer heat reduction up to 64%. Very important is the fact that the glazing contribute much more to heat and at less cost compared to frames after the frame of a window (aluminum or PVC) constitutes 20% of the opening, while the energy pane 80%.

CONTRIBUTION OF DOUBLE GLASS ENERGY ENVIRONMENTAL

According to measurements, for building 15sq.m. dual energy pane Low-e measures released to atmosphere 375 pounds of carbon dioxide CO on the 2nd . By installing, however, estimated to reduce emissions of a household at least 1365 kg CO two , because of the energy savings offered.
