What are the basics to specify and detail energy-efficient windows?
Specify the NFRC Label »
An NFRC label is the only way to establish accurate energy performance characteristics of a window. In order to take advantage of most incentive and energy efficiency/green building programs, NFRC labels on windows are required to establish window performance. NFRC labels are also referenced in many state building codes. Designers should always specify windows with NFRC labels.
Specify ENERGY STAR Windows »
The ENERGY STAR Windows Program is the most prominent national program to recognize superior performance in window products. Designers should always specify windows meeting ENERGY STAR criteria for their region.
Apply Proper Window Details and Installation Practices »
No matter how advanced the glazing and frame materials may be in a window unit, the ultimate performance also depends on the quality of its installation. Designers should always draw and specify proper window installation practices.
