What You Need To Know About Window LabelsNovember 14, 2016
When you venture on a window replacement project, you can see countless window advertisements promising excellent features. Considering the sheer number of options, it can be daunting to identify which products actually perform. Let Renewal by Andersen® of Milwaukee help you understand window labels so you can choose better materials for your replacement units.
NFRC and ENERGY STAR® Labels
The National Fenestration Rating Council (NFRC) is a non-profit organization that tests, certifies, and brands doors and windows based on their energy performance. They help homeowners make a sound decision when it comes to shopping for these products.
ENERGY STAR, on the other hand, is a voluntary platform initiated by the US Environmental Protection Agency. This sets stringent criteria to determine the durability and energy efficiency of products. When you see this label on your replacement windows in Milwaukee, it means you can expect quality performance and longevity.
Energy Performance Ratings
Look for the NFRC and ENERGY STAR labels on the window, as they usually contain information regarding energy efficiency. Here are a few terms you need to be familiar with:
- Visible Transmittance
This specifies the expanse of light that goes through a product. It is often portrayed as a number between 0 and 1. A higher value means more light can enter through your window.
This rate measures the windows’ resistance to heat flow and typically registers between 0.20 and 1.20. Products with a higher value have poor insulating properties. Only a few window choices contain extremely low U-factor like our casement window in Milwaukee. This option is highly energy-efficient and can provide your home with great savings.
- Air Leakage
This indicates the rate of air circulation in windows and doors. A low value means that the seals are tight, preventing leakage and providing more energy savings.
