NFRC LABEL
The NFRC label provides the only reliable way to determine the window energy properties and to compare products. The NFRC label appears on all windows, which are part of the ENERGY STAR program. All of our windows at A. Caspersen Company exceed ENERGY STAR guidelines. NFRC labels on window units give ratings for U-factor, Solar Heat Gain Coefficient (SHGC), Visible Light Transmittance (VT), and optionally Air Leakage (AL) and Condensation Resistance (CR) ratings.
