Low E Window Coating

The owner may think that they have low e windows but have no paperwork to confirm that fact.

Low e window coating.

There are three common applications of. 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. This is but a small sampling of how specific the new generation low e coatings can get.

Fortunately the answer is yes. 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. Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. The solar reflectance of low e coatings can be manipulated to include specific parts of the visible and infrared spectrum.

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. Window manufacturers product information may not list emittance ratings. A low e glass window which stands for low emissivity is simply a windowpane coated in microscopic layers of metallic oxides. 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.

In common use especially building applications the. However though transparent this coating also protects your home from unwanted uv rays. In that case without the use of a low e detection meter is there a way to determine if a window has a low e coating and on what surface of the glass it is applied. Homeowners can test for the low e coating in a window by doing the following.

Stanek windows are made with a variety of high performance energy efficient glass options that can meet your energy performance and budgetary needs. For complete technical information about designing with low e glass read vitro architectural glass technical document td 131. The low e coating is usually placed on one of the inside glass pane surfaces of the insulating unit. Low emissivity low e or low thermal emissivity refers to a surface condition that emits low levels of radiant thermal heat energy.

In addition to energy savings low e also effectively reduces the amount of transmitted ultraviolet light which can damage carpets fabrics and drapes. Hold a lit match or a pen light up in front of the window. What is a low e window. 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.
