windowsWindow replacements can save

Beware of inflated savings claims of "up to" 40% or more. Realistically you may save:

  • About $2 to $8 per window per year, or
  • About 10% to 15% of a typical home's heating bill.

Valid reasons to buy new windows

  • Existing windows are beyond repair.
  • Easier maintenance.
  • Improved comfort.
  • Better resistance to condensation.

What to shop for

  1. ENERGY STAR® qualified windows.
  2. NFRC labels on ENERGY STAR® windows will tell which is more energy-efficient. The lower the NFRC-rated U-factor, the more efficient the window.

Proper installation

Proper installation is necessary:

  • For optimal window performance.
  • To ensure an airtight fit.
  • To avoid water leakage.

Installers should make sure:

  • To follow manufacturers' installation guidelines.
  • All gaps between the window and framing are completely filled with insulation.
  • All air leaks are sealed.
