Low E Window Coatings

The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit.

Low e window coatings.

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. 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. Types of low e coatings passive low e coatings hard coat. The following are used to measure the effectiveness of glass with low e coatings.

Window manufacturers product information may not list emittance ratings. The passive low e coatings are manufactured using the pyrolytic process which. Then you just determine which flame that is and that indicates what surface the low e coating is applied to. Most companies that manufacture vinyl windows offer loe 180 included in the price of the window.

Not all low e coatings are the same. 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. Visible light transmittance is a measure of how much light passes through a window. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes.

Low e glass includes a microscopic transparent coating that reflects infrared energy or heat. Long wavelengths or heat are filtered out while short wavelengths the visible light spectrum are allowed to pass through. 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 argon gas windows.

U value is the rating given to a window based on how much heat loss it allows. Solar heat gain coefficient is the fraction of incident. Recommended for north facing windows. Hold a lit match or a pen light up in front of the window.

If all the flames look identical there is no low e coating present. By comparison low e glass coatings can have an emittance as low as 0 04. Solar control low e coatings soft coat. Low e low e4 glass most people can enjoy optimal energy performance and comfort with low e low e4 glass.

Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation. Homeowners can test for the low e coating in a window by doing the following. 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.
