Energy Saving Glass Improves Our Windows’ Performance

Our windows at The Window Source of Mankato are designed to withstand extreme heat and cold while also providing four-season comfort and energy savings. This keeps your house warm while also saving you money throughout the course of the windows’ lifetime.

Want proof? In addition to meeting or exceeding the requirements for ENERGY STAR® Version 6.0 in all 50 states, we also surpass those for the Northern Zone by up to 48% with certain glass packages. The National Fenestration Rating Council (NFRC) certifies windows and provides the following four common ratings:

  • U-Factor – A measure of the rate of heat flow through a window. A lower U-Factor indicates a higher performing window that can help reduce heating and cooling costs.
  • Solar Heat Gain Coefficient (SHGC) – The amount of solar radiation allowed to pass through a window. The lower the number, the less solar heat gain and UV rays the window permits to enter.
  • Visible Light Transmittance (VT) – Ranging from 0 – 1, visible transmittance is a measure of how much light passes through the window. The higher the number, the more light that can pass through.
  • Condensation Rating (CR) – CR measures how well a window resists the formation of condensation on the inside surface. CR is expressed as a number between 1 – 100.The higher the number, the better a product is able to resist condensation.

See What Our Customers Are Saying About Us

We just had The Window Source install 6 new windows and a sliding door. They look fantastic! All the windows are triple pane and are very efficient and high quality. The fact that they were about 1/2 the price of the competition was a sweet bonus! Aaron and his team did a great job and showed up on time and were very professional. And no high pressure sales tactics – very refreshing. I would recommend The window Source to all my friends and family.

I am so happy with our new windows and new door. Ben installed everything for us, and he did an amazing job! I cannot say enough about the installer, he was on time, professional, fast, and his quality of work is superb . His work ethic is none like I’ve ever seen. We will definitely be using The Window Source again in the future!
