Learn about high-performance, dual-paned windows
Get details on replacing windows
Although PG&E no longer offers a rebate for installing high-performance, dual-paned windows for single-family homes, we still encourage energy-efficient windows as a retrofit product. Such windows are widely available on the market.
Use the information provided on this page to make an educated decision when purchasing energy-efficient windows.
Consider important energy performance ratings
When shopping for windows, search for units with the following energy performance ratings:
- Solar Heat Gain Coefficient of 0.32 or less
- U-Factor of 0.35 or less
These figures are indicated on the National Fenestration Rating Council (NFRC) label affixed to each window or on the manufacturer's order confirmation sheet (available from your contractor).
Increase home comfort and reduce energy costs
Installing high-performance windows can increase the comfort of your home and help you reduce energy costs, condensation and color fading due to sunlight.
Use our window square footage calculator to determine the total area of windows needed. For any questions, call the PG&E Smarter Energy Line at 1-800-933-9555.
