The 4 Energy Performance Ratings by the NFRC

Before you invest in window replacement in Columbia, SC, make sure your choice will increase the energy efficiency of your home. Aside from the improved lighting and ventilation, your windows should also help regulate the climate in your home throughout the changing seasons. This will enhance the overall efficiency of your home, which can lead to cost savings on your energy bills.

When it comes to choosing the right window for your home, we recommend that you evaluate their energy ratings first to ensure that they will satisfy your needs. To help you make an informed product choice, the National Fenestration Rating Council (NFRC) has set a standard for energy efficiency that you can refer to. Here are the four performance ratings that are typically included in an NFRC label:

1. U-Factor – Usually rated between 0.15 and 1.20, this measures the window’s ability to stop heat from escaping your home. Windows in Greenville, SC, with lower U-Factor are more energy-efficient. This can reduce your heating expenses during cold weather.
2. Solar Heat Gain Coefficient (SHGC) – Expressed as a number between 0 and 1, this determines how well a product can block outdoor heat. Smaller SHGC means there is lesser heat transmission in your room. This can help in keeping your room cool during the summer.
3. Visible Transmittance (VT) – Ranging between 0 and 1, VT measures the amount of natural light that can enter through your window. Expect more daylight to flood in your room if the windows have a high VT.
4. Air Leakage – Rated between 0.1 and 0.3, this measures how much air can enter your home through the window. A low air leakage value indicates that there is less chance of draft through the windows. Since this is an optional rating, manufacturers can decide not to include it in their label.
