NEWS ARTICLE ARCHIVESLow Emissivity Glass Energy Tech™ from ViridianViridian EnergyTech™ A clearly superior Low E glassThe foundation for better insulation and solar control. The selection and placement of glass is one of the most important elements in designing a home or building for energy efficiency and year round comfort. Viridian EnergyTech™ and SolTech™ is the first step in the range of energy efficient glasses to economically meet energy rating criteria. Description Viridian EnergyTech and SolTech have a transparent Low E coating applied using patented technology, to form a highly durable hard coating that is integrated onto the glass surface. Unlike ordinary glass, Viridian Low E products provide insulation that keeps your home or building warm in the winter by reflecting heat back into the room, and cool in summer by reflecting the sun's heat. Keeping your home or building cooler in summer and warmer in winter, reduces the need for air-conditioning and heating, which reduces wasteful energy use and greenhouse gas emissions. Viridian EnergyTech and SolTech Low-Emmissivity glass is used either monolithically, as the inner glass in Viridian Thermotech insulated glass units or in solar control laminated glass such as Viridian ComfortPlus. What is low emissivity? Emissivity measures the rate a product emits absorbed heat. The lower the number, the more efficiently the glass reduces heat gain or heat loss, which means a lower U Value and better insulation. For comparison, normal glass has an emissivity of 0.84 and EnergyTech and SolTech is 0.17, which means only 17% of heat absorbed is re-emitted. Likewise, if a solar control glass is used, it acts as a barrier to the absorbed heat in the glass, passing to inside the building. For buildings that require passive heat gains, it allows direct solar radiation to pass through the glass and then traps it inside. So in combination with the correct selection of solar control or thermal insulation glass, EnergyTech and SolTech reduce energy use. Features and benefits
