Window low e coating.

Window manufacturers product information may not list emittance ratings. Rather the effect of the low e coating is incorporated into the u factor for the unit or glazing assembly. Low e coatings play a pivotal role in the performance of your windows can save you money on energy costs and can drastically reduce fading to furniture and décor by blocking uv rays. However though transparent this coating also protects your home from unwanted uv rays.

Most people can enjoy optimal energy performance and comfort with our standard low e low e4 glass offerings. Low emissivity low e or low thermal emissivity refers to a surface condition that emits low levels of radiant thermal heat energy. The solar reflectance of low e coatings can be manipulated to include specific parts of the visible and infrared spectrum. What is a low e window.

A low e glass window which stands for low emissivity is simply a windowpane coated in microscopic layers of metallic oxides. Low e low emissive 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. This is but a small sampling of how specific the new generation low e coatings can get. Double pane windows can be clear tinted or have a low e coating.

However low e coating is not a standalone material. Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. A great advantage of the low e add on for your new energy efficient windows is that you as a consumer have a choice as to just how much insulation you want in your window. A single low e coating on one pane in a double pane unit would likely have a similar insulation value as a standard triple pane unit.

In common use especially building applications the. Additional glass performance options include smartsun glass that blocks 95 of the sun s. There are three common applications of. 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.

However low e coatings play an equally important role and significantly affect the overall performance of a window and the total heating lighting and cooling costs of a building. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes. All materials absorb reflect and emit radiant energy according to planck s law but here the primary concern is a special wavelength interval of radiant energy namely thermal radiation of materials. The coating appears invisible to the naked eye allowing as much natural light into the house as possible.

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. The term double pane refers to a window that has two pieces of glass while low e is a coating technique.
