What the ratings mean
Every window carries an NFRC label. U-factor measures how well the window insulates (lower is better). Solar heat gain coefficient (SHGC) measures how much of the sun's heat gets through (lower is better in Southern California). Visible transmittance tells you how much daylight comes in. We'll show you these numbers for every window we quote.
