The National Fenestration Rating Council (NFRC) is an international coalition that administers testing, certification and labeling of windows, skylights and doors. NFRC sets energy test standards and administers ratings by independent labs. The NFRC energy performance label helps code officials, builders, retailers and consumers reliably compare one product to another by providing detailed performance measures.
The NFRC label, required for code compliance, contains the following performance data:
From a code compliance perspective, there are requirements in Texas code for U-factor, Solar Heat Gain Coefficient (SHGC) and Air Leakage ratings, so having this information in one easy-to-access location in invaluable.
For commercial projects, the NFRC provides the Component Modeling Approach (CMA) Program for Non-Residential Energy Certification and Rating. The CMA Product Certification Program enables whole product energy performance ratings for non-residential fenestration. The NRFC Label Certificate pictured below is used to capture all information needed for non-residential code compliance.
