Low E Window Coating

However though transparent this coating also protects your home from unwanted uv rays.

Low e window coating.

Stanek windows are made with a variety of high performance energy efficient glass options that can meet your energy performance and budgetary needs. A low e glass window which stands for low emissivity is simply a windowpane coated in microscopic layers of metallic oxides. 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. 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.

Rather the effect of the low e coating is incorporated into the u factor for the unit or glazing assembly. The signs of this failure may appear as small round spots within the window cavity. Low e emiscity glass is actually a coating put on one of the inner surfaces of the glass to save energy either by keeping the sun out of the home in the summer or keeping the warmth of home from radiating out of the home in the winter in some cases as the window ages the coating may deteriorate. The coating appears invisible to the naked eye allowing as much natural light into the house as possible.

The solar reflectance of low e coatings can be manipulated to include specific parts of the visible and infrared spectrum. Argon is an inert gas which has higher resistance to heat flow than air and is non toxic colorless and odorless. In hotter climates with east or west facing windows the low e coating is applied to the outer layer of the glazing to help keep the heat out. Window manufacturers product information may not list emittance ratings.
