Best Low E Glass Windows

Low e low emissive glass reflects heat in the summer and helps keep heat inside in the winter making this a good choice in climates where both heating and cooling costs are a concern.

Best low e glass windows.

That means that depending on the type of fuel used in a home low e windows can pay for themselves in 5 to 10 years. A low emittance low e coating is a thin layer of metal that is applied to one side of the glass during the glass manufacturing process. U value is the rating given to a window based on how much heat loss it allows. The coating is nearly invisible and its purpose is to slow the rate at which heat transfers through the glass.

While low e coatings add 10 to 15 percent to the cost of a window research has shown that they cut energy expenditures by about 25 percent over plain insulated glass. Whether a low e coating is considered passive or solar control they offer improvements in performance values. Low e coatings are applied to the various surfaces of insulating glass units. How to find windows with the best low e rating.

The coating can be applied to one or multiple panes of glass and different types of coatings are designed to allow for high moderate or low solar heat gain in cold temperate or hot climates. Low e or low emissivity glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass without minimizing the amount of light that enters your home. The e in low e stands for emissivity which is the ability of the glass to radiate energy these glass windows work in a way same as a silver lining thermos keeping cool things cool and hot things hot.

Low e has the ability to keep the temperature of the surface of the glass facing the interior very near that of the room itself regardless of outside temperatures. This means that not all windows with a low e coating provide the same.

In summation low e windows can block more heat in the summer than clear glass depending upon the low e coating. Most people can enjoy optimal energy performance and comfort with our standard low e low e4 glass offerings. The following are used to measure the effectiveness of glass with low e coatings. Low e glass windows have a microscopically thin coating that is transparent and reflects heat.
