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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
