Not all windows are the same, which is why you should always look for the NFRC label on all replacement windows in Rochester, MN you purchase. Ryan Windows & Siding will help ensure you’re in compliance with the latest energy efficiency standards.

Both the quality and performance of the replacement windows you buy for your home can vary widely, and price is not always the best way to decide which is the best window for you.

The NFRC is the National Fenestration Ratings Council, a lab that tests the thermal performance of windows and will affix a label bearing the NFRC’s name if approved. If you don’t see this label on windows you’re considering, it means the manufacturer has not submitted it for testing and there is no safe way to ensure its performance. That is why homeowners throughout Southeastern Minnesota should always go with a window company with a name and reputation you can rely on to install approved products, Ryan Windows & Siding.

There is a lot of valuable information behind the NFRC label; namely, how well a window has performed in a series of laboratory tests that measure energy efficiency. Check out these important factors:

‍U-value: how well a glass system prevents heat from getting out. The lower the U-value, the better the glass.

‍Solar Heat Gain Coefficient (SHGC): how well a product blocks heat brought on by sunlight.

‍Visible Transmittance (VT): how much light gets through a product.

‍Air Leakage (AL): how much air passes through cracks in the window assembly.

‍Condensation Resistance (CR): how well the product resists condensation on the interior surface.

One of the most important reasons to invest in the products we install as your trusted window company serving homeowners in Rochester, Red Wing and the rest of Southeastern Minnesota, is knowing we install replacement windows from the country’s leading manufacturer — Renewal by Andersen.
