Low-e Glass

What is Low-E glass ? Low-emission glass (Low-E) is a clear glass, it has a microscopically-thin coating of metal oxide. This allows the sun's heat and light to pass through the glass into the building. At the same time it blocks heat from leaving the room, reducing heat loss considerably. Low-E glass became available in 1979 and has been gaining in popularity ever since. It is treated glass that conducts visible light while controlling the passage of heat. Low- E stands for low emissivity. This glass is an energy efficient way to control the heat being allowed in and out of a home or environment. Different types of low-E glass are available to meet the needs of varying climates. Low-e benefits: It's been two decades now since low-e was first introduced to the market. Nobody questions its excellent thermal performance, yet insulating glass wit low-e coating is rarely used in construction. Glass On Web would like to remind you about the benefits and the cost savings achieved by using low-e glass. During the energy crisis of the 1970's the whole world was determined to reduce the natural resource consumption. The major problem in case of glass was the significant heat loss through the glazing surface. The consequence was a lot of wasted energy and money. In 1980 the commercial development of thin, transparent, low emissive coatings literally revolutionized the concept of energy savings in windows. The low-e coating, placed on the inside of the insulating glass unit, enables the sun's short-wave energy to enter the room and at the same time prevents internal warm air from leaving the room. To know more about the benefits, energy and money savings take a look at the related links on the web which we have prepared for you. Low-E glass is glazed with an ultra-thin metallic coating. The manufacturing process applies this with either a hard coat or soft coat process. Soft coated low-E glass is more delicate and easily damaged so it is used in insulated windows where it can be in between two other pieces of glass. Hard coated low-E glass is more durable and can be used in single paned windows. It can also be used in retrofit projects. Obviously, the price tag of windows with Low E glass or even applying Low-e glass coating on the windows you have right now would probably not be cheap. What you would have to look forward to would be decreasing energy bills and the amount you have saved in time will pay for the windows.
