Low E Glass Windows

Visible light transmittance is a measure of how much light passes through a window.

Low e glass windows.

The following are used to measure the effectiveness of glass with low e coatings. Low e stands for low emissivity. Low e glass windows have a microscopically thin coating that is transparent and reflects heat. So a low emissivity glass will emit less heat than one with high emissivity.

Greater reflection screens out more uv light and is important where solar heat gain is the primary concern. By blocking most ultraviolet uv radiation low e glass helps protect fabrics leather carpeting. Solar heat gain coefficient is the fraction of incident. Two types of low e glass soft and hard coat look and perform differently.

Low e glass might be placed between two panes of glass. Get free shipping on qualified low e glass sliding windows or buy online pick up in store today in the doors windows department. This glass is an energy efficient way to control the heat being allowed in and out of a home or environment. Windows can be responsible for 25 of a home s wintertime heat loss.

This is but a small sampling of how specific the new generation low e coatings can get. When we talk about low e in windows we are generally referring to coatings inside the glass unit that reflect outside heat and light from the sun. Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. Low e or low emissivity glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass without minimizing the amount of light that enters your home.

Low e glass windows offer insulation against heat and cold. U value is the rating given to a window based on how much heat loss it allows. 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. Emissivity refers to the amount of heat that the glass is able to emit.

Low e has the ability to keep the temperature of the surface of the glass facing the interior very near that of the room itself regardless of outside temperatures. This table will compare glass r values. Low e glass is a type of treated glass that that conducts visible light while controlling the passage of heat. Low e stands for low emissivity and has become a standard material for windows and doors since it first arrived on the scene in earnest in the 1980s.

In addition to reducing. Soft coat low e glass has a higher r value.
