Low E Window Coatings

Low e glass includes a microscopic transparent coating that reflects infrared energy or heat.

Low e window coatings.

Hold a lit match or a pen light up in front of the window. There are three common applications of low e coatings for residential 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. 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.

Solar control low e coatings are manufactured using the magnetron sputtering. U value is the rating given to a window based on how much heat loss it allows. Not all low e coatings are the same. 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.

By comparison low e glass coatings can have an emittance as low as 0 04. Recommended for north facing windows. Visible light transmittance is a measure of how much light passes through a window. Low e argon gas windows.

Solar control low e coatings soft coat. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes. The passive low e coatings are manufactured using the pyrolytic process which. Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation.

The following are used to measure the effectiveness of glass with low e coatings. Window manufacturers product information may not list emittance ratings. If all the flames look identical there is no low e coating present. Types of low e coatings passive low e coatings hard coat.

Low e coatings were developed to minimize the amount of ultraviolet and infrared light that passes through glass without compromising the amount of visible light that s transmitted. Low e low e4 glass most people can enjoy optimal energy performance and comfort with low e low e4 glass. Loe 180 the standard low emissivity coating helps keep the warmth inside your home and reduces harmful effects of uv. Solar heat gain coefficient is the fraction of incident.

Most companies that manufacture vinyl windows offer loe 180 included in the price of the window. The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit. 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.
