Energy Star Performance
Meeting the most stringent requirements for energy efficiency.
As a long-standing Energy Star Partner, we’re dedicated to designing, building and engineering our windows and patio doors for optimal energy efficiency.
In addition to Energy Star ratings, the National Fenestration Rating Council (NFRC) has established testing criteria that measure three areas of window performance:
- Thermal performance
- Solar heat gain
- Visible light transmittance
So when you really want to find out how good any Hurd product is, just check the NFRC label right on the window. Our Product Performance Guides also contain this information.
