If you have plans to invest in replacement windows, one of the things you need to consider is how well they can contribute to your home’s energy efficiency. To help you make informed choices, it helps to understand the labels that come with them. One such label is provided by NFRC, or the National Fenestration Ratings Council. It is the organization responsible for creating energy performance metrics for windows, as well as doors and skylights.
Understanding NFRC Labels
The NFRC labels indicate information about the windows’ interactions with heat and air — two elements that impact your home’s energy efficiency and comfort. It lists down energy performance metrics with their corresponding ratings. In the context of replacement windows, the following are the most notable:
- U-Factor, which measures heat insulation.
- Solar Heat Gain Coefficient (SHGC), which measures how much solar radiation a window can allow.
- Visible Transmittance (VT), which indicates how much visible light a window can let in.
These metrics are expressed by a figure between 0 and 1. Windows with lower U-Factor and SHGC means they provide better insulation and allow less heat into your home, respectively. A higher VT means more natural light can enter your home through the window.
The Role of NFRC Labels in Window Replacement
When planning a window replacement, the NFRC label becomes a handy tool. It allows you to compare windows and choose one that balances energy efficiency with cost. You might prefer a unit with a lower U-Factor for better insulation in colder months or one with a higher VT for brighter home interiors.
