Window Low E Coating

What is a low e window.

Window low e coating.

The solar reflectance of low e coatings can be manipulated to include specific parts of the visible and infrared spectrum. 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. However low e coating is not a standalone material. 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.

The term double pane refers to a window that has two pieces of glass while low e is a coating technique. Window manufacturers product information may not list emittance ratings. In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes. In common use especially building applications the.

Additional glass performance options include smartsun glass that blocks 95 of the sun s. The coating appears invisible to the naked eye allowing as much natural light into the house as possible. However though transparent this coating also protects your home from unwanted uv rays. 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.

It requires a sheet of glass as a base material for its application. For complete technical information about designing with low e glass read vitro architectural glass technical document td 131. 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.

Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. 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. 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.

Rather the effect of the low e coating is incorporated into the u factor for the unit or glazing assembly. 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. Stanek windows are made with a variety of high performance energy efficient glass options that can meet your energy performance and budgetary needs. 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. 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.
