Low E Window Coatings

There are three common applications of low e coatings for residential windows.

Low e window coatings.

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 argon gas windows. If all the flames look identical there is no low e coating present. Low e low e4 glass most people can enjoy optimal energy performance and comfort with low e low e4 glass.

Window manufacturers product information may not list emittance ratings. Recommended for north facing windows. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes. Homeowners can test for the low e coating in a window by doing the following.

Hold a lit match or a pen light up in front of the window. Loe 180 the standard low emissivity coating helps keep the warmth inside your home and reduces harmful effects of uv. The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit. Solar control low e coatings soft coat.

U value is the rating given to a window based on how much heat loss it allows. Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation. Types of low e coatings passive low e coatings hard coat. Not all low e coatings are the same.

By comparison low e glass coatings can have an emittance as low as 0 04. Most companies that manufacture vinyl windows offer loe 180 included in the price of the window. Solar control low e coatings are manufactured using the magnetron sputtering. 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.

Low e glass includes a microscopic transparent coating that reflects infrared energy or heat. Solar heat gain coefficient is the fraction of incident. Long wavelengths or heat are filtered out while short wavelengths the visible light spectrum are allowed to pass through. Visible light transmittance is a measure of how much light passes through a window.

Then you just determine which flame that is and that indicates what surface the low e coating is applied to. The following are used to measure the effectiveness of glass with low e coatings. 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.
