Quick Answer:

LoĒ-366 features a triple-layer silver coating that blocks up to 95% of UV rays and significantly reduces solar heat gain compared to standard Low-E glass. For south- or west-facing rooms exposed to intense sunlight, upgrading to LoĒ-366 provides maximum cooling savings, interior fade protection, and year-round energy efficiency.

If you have a room in your home with South or West exposure, you know exactly how hot it can get when the sun shines down throughout the day. Standard window glass lets an excess of solar heat pass through it. This allows for extremely high air conditioning bills, along with interior damage.  At FixHomeGlass, we specialize in high-performance glass replacement solutions that use advanced Low-E (Low Emissivity) coatings, which will send this infrared heat back outside while still allowing visible light to come into the home.

The Evolution of Solar Protection

There are many advantages to using low-e coated glass instead of untreated or clear glass. However, the performance of different types of coatings can vary. The majority of Low-E coated windows create a balance between heating and cooling efficiency depending on the time of year, so when selecting a low-e window for south-facing rooms, you’ll want to select either a product with the greatest amount of heat reflectivity or one that provides the most effective solar control, known as the “ultimate solar barrier” or LoĒ-366.
  • Standard Low-E: This microscopically thin metallic coating reflects heat and blocks a significant portion of UV rays, protecting your carpet and fabrics from damage. Standard Low-E coatings are an excellent choice when improving energy efficiency throughout your home by upgrading from untreated or clear glass.
  • Cardinal LoĒ-366: This superior-quality Low-E coating is manufactured by Cardinal Glass Industries. This coating consists of three layers of silver-based coating on the outside of the glass to provide the most solar control and UV protection available in the industry.

Is the Upgrade Worth the Money?

Many homeowners in the Chicago suburbs ask, “Is high-performance glass really worth the extra cost?”. Statistically, LoĒ-366 glass has many advantages for rooms which are highly sunlit. Here are just a few of the most important:
  • Maximum Cooling Savings: By reflecting most of the sun’s heat energy off your windows, your air conditioner won’t have to work nearly as hard, which means your monthly utility bill will be significantly lower.
  • Best UV Protection: Regular windows allow in those damaging rays which fade your furniture and hard wood floors and LoĒ-366 will block 95% of those damaging rays, allowing the beauty of the interior of your home to be preserved longer.
  • Unmatched Clarity: Even though LoĒ-366 has a coating on it, it will still provide a great deal of visibility so your rooms will always be well lit without letting heat into your home.
  • Year-Round Performance: When it’s cold outside, the LoĒ-366 coating will provide warmth by reflecting the heat back into your home that would otherwise be lost through the windows, allowing the existing framing of your windows to be more energy efficient

Frequently asked questions

What is the difference between Standard Low-E and Cardinal LoĒ-366 glass?
Standard Low-E uses a thin metallic coating to reflect heat and block a portion of UV rays. Cardinal LoĒ-366 uses a triple-layer silver coating designed for maximum solar heat control, UV blockage, and energy efficiency, particularly in rooms with heavy sun exposure.
South and West-facing rooms receive direct sunlight for long stretches of the day, causing significant heat buildup. LoĒ-366 acts as an "ultimate solar shield," reflecting solar heat away from the glass to keep interior spaces cooler and reduce air conditioning costs.
Yes. FixHomeGlass performs glass-only replacements year-round in any weather. The installation process is fast and minimized to prevent long exposure of your home to outside elements.
