Read the label: U-factor and SHGC
| Number on the NFRC label | What it means | In hot climates |
|---|---|---|
| U-factor | How fast heat moves through the whole window | Lower is better |
| Solar heat gain coefficient (SHGC) | How much of the sun's heat comes through the glass | Lower is better: it keeps rooms cooler |
| Visible transmittance | How much daylight comes through | Higher means brighter rooms |
ENERGY STAR sets window criteria by climate zone. Ask to see the label for each window you are quoted.

Frequently asked questions
What windows are best for Texas heat?
Look for ENERGY STAR-certified windows with low-E glass and a low SHGC, which blocks more of the sun's heat. Double-pane glass with an insulating gas fill and a well-insulated frame helps too.
How long does window replacement take?
Most homes take one to two days once the windows arrive. Custom windows are made to measure, which takes a few weeks.
Do new windows reduce noise?
Yes, double-pane windows that are properly sealed noticeably reduce outside noise, and laminated glass reduces it more.
Can hail break windows?
Large hail can crack glass and frames and tear screens. Our free Storm Check shows the hail reported near your address.
Can I finance new windows?
Yes, qualified homeowners can finance windows alone or together with a roof, siding or gutters. See how financing works.
