The See-Thru Windows and Doors Difference
The Label Tells the Real Story
What designations and labels are on your home improvement products are important. Designed to help consumers measure and compare energy performance of different window brands, The National Fenestration Rating Council (NFRC), provides consistent benchmark ratings on performance characteristics of different window and door brands, allowing you to compare different brands by the same fair standards.
Many manufacturers may make claims as to how their products perform, but they may not provide you with the actual printed copy of the NFRC label. Without the label, there’s no guarantee as to how or where the products were tested. We’ve invested time and money to provide consumers certified performance data so you can be certain that our products will perform for you. Our windows are also made in the US, so you can count on quality. We believe all of our home improvement products should be made of the highest quality materials available, and that all of our installers should be experienced so you get the most for your money.
