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.

Reviews

"We had a large picture window and two side windows replaced. Everyone from the person who took our order to the installers were top notch. We got exactly what we wanted. Granted, we had to wait a few months, just like you do for everything these days, but we were told that up front. The windows were well worth the wait. We've replaced windows before by going to home maintenance stores. Don't waste your money on those. Our Renewal by Andersen windows look great, they operate like a dream, and are worth every penny. Quality through and through."
