Glaverbel's Energy glass combines both of these functions in a single product thanks to its invisible, precious-metal coating which prevents loss of heat in winter, while screening out heat in summer.The Energy balance in summer: hot outside, cool and light insideEnergy offers an excellent solar factor (39%), which means that it reflects 61% of the heat produced by the sun's rays to back to the outside world.This is a superb performance level when compared to a conventional low-emissivity glass, which rejects just 30 to 40% of solar radiation.
Another benefit: Energy features a superb light transmission rating of 71%, thereby encouraging the influx of light into the interior of the building. Its extremely low light reflection (12%) and neutral appearance make it an ideal choice for residential applications.
The Energy balance in winter: cold outside, warm inside
When used in double glazing, Energy also offers excellent insulation to protect against the winter cold. With an extremely low U-value of 1.1 (W/m².K)*, Energy leads to a significant reduction in losses of heat to the outside world.
Energy not only provides protection from summer heat waves, but also from harsh winters, by ensuring a higher level of comfort within the building. Energy generates significant energy savings, a bonus for the environment, because by reducing the consumption of heating and/or air conditioning, Energy reduces emissions of CO2.
additional benefits, such as acoustic insulation and security/safety features. It is ideal for residential use and in tertiary applications (hospitals, public services, hotels, businesses, etc.).
