What is Low E 270 glass?

The sun doesn't stand a chance against Cardinal Loå2-270 (pronounced low E squared-270). It's the perfect glass for fighting the heat. It reduces solar heat gain by 50% or more when compared to ordinary glass. In fact, its solar heat gain coef- ficient is better than code requirements.

In this way, what is Low E 272 glass?

Low-E 272 Glass delivers year-round comfort, reflecting an intermediate level of heat back into the room in winter and rejecting the sun's heat and uv rays in summer. This product's patented coating provides clarity and high-performance low-solar control, reducing window heat gain by 50% compared to ordinary glass.

One may also ask, are there different types of low E glass? There are two types of Low-E glass: hard coat and soft coat. As you might imagine, they have different properties. In fact, they actually look different. Hard coat Low-E glass is manufactured by pouring a thin layer of molten tin onto a sheet of glass while the glass is still slightly molten.

Similarly, you may ask, what is the purpose of low E glass?

Low-E, or low-emissivity, glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass, without minimizing the amount of light that enters your home. Low-E glass windows have a microscopically thin coating that is transparent and reflects heat.

Is Low E glass worth?

Low-e glass options are definitely worth the investment. For just a few more dollars than standard glass, you get the energy savings and protection from low-e glass. And that little extra cost can pay for itself with the money you'll save on utility bills!

How can you tell if glass is low E?

Homeowners can test for the low-e coating in a window by doing the following:

Hold a lit match or a pen light up in front of the window.
If the window contains low-e glass, one of the images will be a different color than the rest of the images.

Does Low E glass go inside or outside?

In double glazed windows low-e glass can be specified on a particular side of the glass depending on what you want to achieve. For warm climates where summer heat reduction is a priority, the coating should be on the inside facing surface of the outside pane (surface #2).

What is low e4 glass?

Our standard Low-E4 glass package features a double-glazing design that deflects infrared rays from the sun, keeping your interior from getting too hot. This glass package is 56% more energy-efficient in summer and 47 percent more energy-efficient in winter compared to regular dual-pane glass.

What is low e3 glass?

Overview. Low-emissivity coatings consist of ultra-thin layers of tin dioxide, silver or other metals applied to a pane of glass. In 2010, manufacturers introduced low-E3 -- or low-E cubed -- windows, which feature three coats of metal to further reduce solar heat transfer through the glass.

What does the E in low E stand for?

Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy.

What is Low E SmartSun glass?

SmartSun™ Glass. SmartSun™ glass gives you the benefits of Low-E glass, plus it helps shield your home from the sun's heat and filters out 95% of harmful UV rays while letting sunlight shine through. Ideal for: All Climates. Available on: SmartSun™ glass is available on all Andersen® products.

What is soft coat Low E glass?

Soft coat low e uses a thin layer of silver, applied using a 'sputter' process to a pre-cut section of glass in a vacuum chamber at room temperature. The finish is referred to as 'soft coat' as the coating remains fairly delicate (which is why soft coat is always found on face two or three).

What are low E impact windows?

Low-E stands for low emissivity and is basically a microscopic, metallic coating applied to a surface of glass that reflects and re-radiates heat energy into or out of a home depending on climate conditions. Using Low-E is an excellent way to increase the energy efficiency of a window.

How long do low E windows last?

10 to 15 years

How much more expensive is low E glass?

Low-e window film can be installed in most commercial spaces for between $5 and $8 per square foot. Some recently introduced high visible light transmission low-e films (70% visible transmission) are more expensive, with installed costs of $12 to $15 per square foot.

How long has low E glass been around?

It has been 20 years since low-E was introduced to the North American glazing market. The product has developed from a premium option limited to residential windows in cold, Northern markets, to now a standard window component across many glazing applications.

How long does argon gas in Windows last?

20 years

How do you clean low E glass?

Scrub the wet area with a clean, lint-free towel or cloth. Wipe dry with a dry, clean lint free towel or cloth. DO NOT USE A SQUEEGEE on the Low'E' coated (interior) surface. To prevent streaking, stop wiping when the glass is almost dry and there is a uniform film of moisture left on the glass surface.

Do Low E windows save energy?

Low E Windows Reduce Energy CostsLow E applied to windows helps block infrared light from penetrating the glass from the outside. Bottom line: they are much more energy-efficient, helping you save on heating and cooling costs.

How do I know if my windows have argon gas?

Look at the NFRC sticker on the windows. ABOVE the NFRC ratings for the windows, it should tell you the Mfgr., the series, and then give a brief description of the window -- things like "dual glazed", "low-E glass", "argon", The low-E is easy -- the windows will have a slight green tint to them.

What is Low E glass with argon?

Low E or low emissivity coating is a unique microscopic glaze that helps minimize the amount of ultraviolet, infrared and visible light from penetrating the glass keeping you cooler in the summer and warmer in the winter. Another benefit of Low E & Argon Gas windows is the ability to control solar heat gain.

What is the difference between low E glass and clear glass?

Low-e windows do limit the visual quality of the window slightly. When compared to a clear window close up, it is difficult to see a difference. But when the windows are viewed from farther back in sunlight, the low-e coated window has a slight grayish tint.

Can you grow plants with low E windows?

Low-E windows may provide a beneficial growing environment because they block some UV radiation. Select plants that require medium direct sunlight for best results. Place the plants about 12 inches away from the windows for ideal light exposure.
