How do you read a NFRC label for windows?
NFRC certified product allows consumers to compare the efficiency of windows. NFRC labels for windows include ratings for U-factor, Solar Heat Gain Coefficient (SHGC), Visible Light Transmittance (VT), and optionally Air Leakage (AL) and Condensation Resistance (CR).
U-Factor measures how much heat escapes through a window. This is important if you live in a cold region. The lower the number the less heat will escape.
Range: 0.20 – 1.20
SHGC measures how much solar radiation is admitted through a window. This is important in hot regions. The lower the number the less heat is admitted.
Range: 0 – 1
VT indicates how much visible light is transmitted through a window. A higher number means more natural light.
Range: 0 – 1
The air leakage rating tells us how much air will enter a room through the window. A lower number indicates less air will pass through cracks in the window assembly.
Range: 0.1 – 0.3
All windows are prone to condensation The condensation resistance rating measures how well a window will resist the formation of condensation on the inside surface. Lower is better.
Range: 1 – 100
