Best Low E Glass Windows

U value is the rating given to a window based on how much heat loss it allows.

Best low e glass windows.

In summation low e windows can block more heat in the summer than clear glass depending upon the low e coating. Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. This means that not all windows with a low e coating provide the same. 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.

Low e coatings are applied to the various surfaces of insulating glass units. 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. Low e windows provide an advantage in performance over standard glass primarily in winter heat retention. Tempered glass low e coatings.

How to find windows with the best low e rating. Low e glass comes in many forms. Additional glass performance options include smartsun glass that blocks 95 of the sun s. 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.

The coating is nearly invisible and its purpose is to slow the rate at which heat transfers through the glass. The following are used to measure the effectiveness of glass with low e coatings. 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. Low e glass windows have a microscopically thin coating that is transparent and reflects heat.

Low e glass reduces the amount of harmful rays like ultraviolet and infrared that enter the house through the 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.

This is but a small sampling of how specific the new generation low e coatings can get. Most people can enjoy optimal energy performance and comfort with our standard low e low e4 glass offerings. 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. 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.
