Low E Window Coatings

Low e 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.

Low e window coatings.

Types of low e coatings passive low e coatings hard coat. The passive low e coatings are manufactured using the pyrolytic process which. Loe 180 the standard low emissivity coating helps keep the warmth inside your home and reduces harmful effects of uv. If one of the flames looks slightly clearer and is a different color or hue from the other three that indicates a low e coating.

Then you just determine which flame that is and that indicates what surface the low e coating is applied to. Low e low e4 glass most people can enjoy optimal energy performance and comfort with low e low e4 glass. Solar heat gain coefficient is the fraction of incident. Visible light transmittance is a measure of how much light passes through a window.

The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit. Window manufacturers product information may not list emittance ratings. There are three common applications of low e coatings for residential windows. Solar control low e coatings are manufactured using the magnetron sputtering.

Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation. Hold a lit match or a pen light up in front of the window. Homeowners can test for the low e coating in a window by doing the following. The following are used to measure the effectiveness of glass with low e coatings.

Not all low e coatings are the same. U value is the rating given to a window based on how much heat loss it allows. Low e argon gas windows. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes.

Recommended for north facing windows. Low emittance low e is a coating that increases a window or door s ability to diminish heat transfer thus saving heating and cooling costs. Low e glass includes a microscopic transparent coating that reflects infrared energy or heat. Solar control low e coatings soft coat.

If all the flames look identical there is no low e coating present. Low e meaning low emissivity is an extremely thin layer of metallic particles or more commonly several layers applied to the glass that in simple terms allows the glass to act like a sieve. By comparison low e glass coatings can have an emittance as low as 0 04.
