For Manufacturers

What is the process to become a recognized energy-efficient window manufacturer?

Join NFRC and Label Products »

In order to take advantage of most incentive and energy efficiency/green building programs, manufacturers are required to use NFRC labels on windows to establish window performance. NFRC labels are also referenced in many State building codes.

Join the ENERGY STAR Windows Program »

The ENERGY STAR Windows Program is the most prominent national program to recognize superior performance in window products. Participation in the ENERGY STAR Windows Program is contingent on using NFRC labels.

Join the EWC Product Database »

The Efficient Windows Collaborative Window Selection Tool links consumers directly to a database of participating window manufacturers and their products. Participation in the EWQC product database is contingent on using NFRC labels and participating in the ENERGY STAR Windows Program.
