By comparison low e glass coatings can have an emittance as low as 0 04.
Low e window coatings.
U value is the rating given to a window based on how much heat loss it allows.
Recommended for north facing windows.
Types of low e coatings passive low e coatings hard coat.
Solar heat gain coefficient is the fraction of incident.
Low e glass includes a microscopic transparent coating that reflects infrared energy or heat.
Solar control low e coatings are manufactured using the magnetron sputtering.
The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit.
Not all low e coatings are the same.
Most companies that manufacture vinyl windows offer loe 180 included in the price of the window.
Solar control low e coatings soft coat.
The following are used to measure the effectiveness of glass with low e coatings.
Such glazing would emit only 4 of the energy possible at its temperature and thus reflect 96 of the incident long wave infrared radiation.
In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes.
Visible light transmittance is a measure of how much light passes through a window.
Hold a lit match or a pen light up in front of the window.
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.
There are three common applications of low e coatings for residential windows.
If all the flames look identical there is no low e coating present.
Homeowners can test for the low e coating in a window by doing the following.
Low e argon gas windows.
Long wavelengths or heat are filtered out while short wavelengths the visible light spectrum are allowed to pass through.
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.
Loe 180 the standard low emissivity coating helps keep the warmth inside your home and reduces harmful effects of uv.
Window manufacturers product information may not list emittance ratings.
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 low e4 glass most people can enjoy optimal energy performance and comfort with low e low e4 glass.
Then you just determine which flame that is and that indicates what surface the low e coating is applied to.
