UNDERSTANDING LOW-E GLASS ON YOUR WINDOWS

Windows are ideal energy-saving solutions for your home. They provide insulation because of its components, mainly the glass. Through advancements in technology, manufacturers have developed low-E glass for solar and thermal performance.

Understanding Low E Glass Windows

How Does It Work?
When your windowpane absorbs heat or light energy, it radiates it back. This process is called emissivity. The amount of heat radiated depends on the emissivity value and temperature of surfaces. Windows with low emissivity values are better insulators, and this is due to low-E glass.

Low-E glass has a coating that minimizes the amount of ultraviolet (UV) and infrared light that passes through, without compromising visible light transfer. St. Charles, Missouri, energy efficient windows with this type of glass reflects interior temperature back inside your home. This way, cool or warm air will not escape through your windows.

The coating affects the overall performance of all types of windows, including casement windows in St. Charles, MO. This means that it affects the following performance ratings:

  • U-value – This measures how much heat is lost in your windows.
  • Visible light transmittance – This rates how much light passes through the glass.
  • Solar heat gain coefficient – This is the fraction of solar radiation that your window lets pass through.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"We had a wonderful experience with Renewal by Anderson of St. Louis. From sales to office staff communication to installation everything was great. Our new windows are great quality, look amazing and improved the overall look of our house. We had four installed in August and will definitely be purchasing from Anderson for the rest of our windows in the future. I highly recommend! ❤️ Now it just needs to cool off outside so I can open them. 😃"
