Low-E Glass for the Home

Low-Emissivity Window Glazing or Glass

Low-emissivity (Low-E) coatings on glazing or glass control heat transfer through windows with insulated glazing. Windows manufactured with Low-E coatings typically cost about 10%–15% more than regular windows, but they reduce energy loss by as much as 30%–50%.

A Low-E coating is a microscopically thin, virtually invisible, metal or metallic oxide layer deposited directly on the surface of one or more of the panes of glass. The Low-E coating reduces the infrared radiation from a warm pane of glass to a cooler pane, thereby lowering the of the window. Different types of Low-E coatings have been designed to allow for high solar gain, moderate solar gain, or low solar gain.  A Low-E coating can also reduce a window’s visible transmittance unless you use one that’s

To keep the sun’s heat out of the house (for hot climates, east and west-facing windows, and unshaded south-facing windows), the Low-E coating should be applied to the outside pane of glass. If the windows are designed to provide heat energy in the winter and keep heat inside the house (typical of cold climates), the Low-E coating should be applied to the inside pane of glass.

Window manufacturers apply Low-E coatings in either soft or hard coats. Soft Low-E coatings degrade when exposed to air and moisture, are easily damaged, and have a limited shelf life. Therefore, manufacturers carefully apply them in insulated multiple-pane windows. Hard Low-E coatings, on the other hand, are more durable and can be used in add-on (retrofit) applications. The energy performance of hard-coat, Low-E films is slightly poorer than that of soft-coat films.

Although Low-E coatings are usually applied during manufacturing, some are available for do-it-yourselfers. These films are inexpensive compared to total window replacements, last 10–15 years without peeling, save energy, reduce fabric fading, and increase comfort.

What is  Smart Glass?

E-Glass stands for Electric Glass and is often known under the names smart glass or switchable glass. The surname(s) electric, smart, and/or switchable refer to the fact that when voltage is applied to the glass, it switches from glazed to transparent and can be set to any opacity level in between to help block out the sun or to only let a little bit of light in. E-Glass can be made into just about any size you need and can be used in many different applications.

What are the benefits of E-Glass for homeowners?

Energy savings. With such a low voltage output, the addition of E-Glass in your home becomes even better by only adding a few dollars to your monthly electric bill. Adding E-glass can also help save money on heating and cooling costs and is a great alternative to motorized light screens, blinds and/or curtains.

Privacy. E-Glass is naturally frosted when the power is not on to give you privacy in your bedroom as a room divider so you can get dressed or to prevent people outside from seeing in your home. When you’re done, simply turn on the power and the glass switches back to clear so you can see what’s happening outside your house or in the other room.

UV protection (99% when frosted). The sun can do very harmful damage to people and pets. With the 99% UV protection given by this glass (when frosted) you can protect yourself from the harmful sun when in your home or if you want to enjoy the weather on your patio without getting a sunburn. All of this UV protection is given by the glass but only when the power to the glass is turned off.

Rear projection displays (when frosted). Rear Projection Displays can add life to any window, door, or pane of glass. Using a thin film that adheres to one side of the window, we make it so that a plain window, door, or pane of glass can become an animated work of art, a sunscreen, or even a movie screen for the whole family to enjoy.

Holographic displays (when clear). E-glass can turn your normal projector into a holographic rear projector by simply projecting your image onto the back of the glass, and it will display on the front of the glass or the “viewing side.”
