What to compare before you choose
- Insulating value. Lower U-factor means less heat loss. Look for ENERGY STAR ratings for your climate zone.
- Solar heat gain. Lower SHGC blocks more heat from sunlight, useful in hot climates.
- Frame material. Vinyl is affordable and low-maintenance. Fiberglass and wood cost more but offer other strengths.
- Full-frame vs. insert. Insert windows fit existing frames. Full-frame replacement costs more but fixes rot and air leaks.
