For many homeowners, the different labels and energy ratings plastered on window installation products can be quite puzzling. It’s one of the trickiest parts of trying to make the most energy-efficient choice. Two of the most common labels you may find on these windows are the ENERGY STAR® and the National Fenestration Rating Council (NFRC) labels.
You know that they indicate a window’s energy efficiency, but what do they exactly mean to you and how can you use them to your advantage? Most especially, what’s the difference between the two? Renewal by Andersen® of Connecticut, your trusted local window company, has the answers.
Key Difference Between the ENERGY STAR and the NFRC Labels
When planning for a new window installation, the two labels you should make sure to find are the ENERGY STAR and NFRC labels. While the ENERGY STAR label tells you evidently if a window is energy-efficient, the NFRC label guides you in choosing which product is more energy-efficient by breaking down their energy performance.
The NFRC label compares window products according to various ratings, such as:
- U-Factor – It measures the amount of heat lost or gained through your window.
- Solar Heat Gain Coefficient (SHGC) – It tells you how much solar radiation and heat enters your home through your window.
- Visible Transmittance – It indicates the amount of light that is allowed to enter your window.
- Air Leakage – It measures how much air a window allows to pass through.
To put it simply, the ENERGY STAR label is like the “less sugar” tag in drinks and the NFRC label is the nutrition information box. Both labels work together to help you determine the most suitable and energy-efficient option for your home.
