Our windows are built to resist the heat and cold, offering four-season comfort. This not only keeps you comfortable, but also saves you money through energy savings. Need proof? We meet or exceed the current standards for ENERGY STAR® Version 6.0 requirements in all 50 states and can exceed requirements for the Northern Zone, by up to 48% with select glass packages. Below are four common ratings that are provided for windows certified by the National Fenestration Rating Council (NFRC).
- 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 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.

Energy Miser glass options keep you warmer in the winter and cooler in the summer.
All Energy Miser Options Are UV Resistant
Harmful UV rays can do more damage to your home than you might think. For example, if you don’t use the proper precautions on your windows, these rays can fade valuable items you have inside your home. Our UV resistant windows can act as a sunscreen for your house, blocking damaging ultraviolet rays without noticeably reducing the light coming inside. The Low-E coating options on our windows increase window performance and help to significantly reduce fading and sun damage to your furnishings, carpets and floor, so they stay colorful and beautiful. In the winter radiant heat produced by your heating system is reflected back into your home. In the summer radiant heat from the sun is reflected so that the load on your cooling system is greatly reduced. Unlike dark tinted glass, LowE glass allows almost all visible light to pass through. All of these energy saving features will save you money!

"I wish I could give more stars on the review! The experience of purchasing from The Window Source could not have gone any better! Such great professionalism in the work team, the installers worked amazing and were polite, words can't Express how great everything turned out."
– Arturo Acosta, 5 Star Review via Google
"We needed all our windows in our house replaced due to a catastrophic hail storm. Our windows in the front of the house were boarded up due to the storm. Window Source was so helpful to come by and measure, order and replace our windows. They did a very professional job and made sure we were satisfied with the work. I would recommend them to anyone who wants a reasonable price to replace windows and a quick professional installation."

"Sandy with the Window source by far has the best customer service, she kept me informed and far exceeded our expectations when finding us the best price that fit our needs. I don't ever write reviews but was so happy with the experience I felt the need to share. We love our new windows and would highly recommend The Window Source to anybody looking to replace their windows!"

"I’ve been remodeling and flipping homes for several years now and believe me when I say this, “Window Source of West Texas is the BEST and EASIEST company to deal with!” In the past I’ve had horrible experiences with contractors showing up late, not showing up at all, leaving a mess, making a mess, doing mediocre work & the list goes on.
Abraham Loewen has been the same technician on 2 of my job sites and he has further exceeded my expectations every time. Not only did he pick up after he was done, he went back and cleaned every window plus frame individually. The time it took him to finish was a few hours for 10+ windows.
I’m extremely happy with the service/work/quality they provide. Huge thanks to Vanessa the sales lady that helped us choose our windows and provide us a quote. Sandy was super nice and scheduled everything to go as smooth as possible. I would highly recommend using them. I will refuse to use anyone else!"

"The Window Source of West TX is an EXCELLENT place with a top quality product, quick & meticulous install, and exceptional customer service! They gave us the best pricing from all previous estimates we've had in the past. We had 15 windows replaced and wrapped and the difference it's made to my home is unbelievable. They not only look amazing, but it feels amazing inside as well. I actually got cold for the first time during the summer. They made the entire process from start to finish so easy and I would highly recommend them to anyone! One happy customer for sure."
