Low-E windows

Glass and frames chosen for San Diego sun

In this county the energy conversation is usually afternoon sun, not a frozen January. West and south glass is where a low-E coating and a second pane change how a room feels. The permit, if one is required, will care about the label on the unit, not about a marketing name. Pane Pro SD refers a contractor who should read that label with you.

What do homeowners ask about Energy-efficient windows?

What should I look at on the label?

U-factor and solar heat gain coefficient, on the NFRC label for the unit being ordered. Ask the contractor which climate zone the building department uses for your address and what that zone expects.

Is this the county weatherization program?

No. County and utility assistance programs have their own rules and income tests. This page is about buying replacement windows. Eligibility is decided by those programs, not by Pane Pro SD.

Is a gas fill between the panes required?

Not by this site. Some insulated units use argon. Ask what the quoted unit actually contains and how that shows up on the label. Do not pay for a feature that is not written down.

Will new glass cut my bill by a set percent?

Nobody honest can promise that from a webpage. Sun, shade, the rest of the house, and how you cool it all matter. Ask for a scope, not a savings guarantee.
