Cost of Replacing Home Windows in Atlanta

Windows can be one of your home’s most attractive features. Windows provide views, daylighting, ventilation, and heat from the sun in the winter. Unfortunately, single pane windows account for 30 to 45% of your energy bills.

The following is from Paul Fisette from Fine Home Building: “In a cold climate we welcome the sun’s heat and light most of the time. And once we capture the heat, we don’t want to give it up. In a warm climate, we don’t want the heat, but we do want the light. Advances in window technology let us have it both ways.  Low-E coatings improve the insulating value of a window roughly as much as adding an additional pane of glass does. And combining low-E coatings with low-conductance gas fillings, such as argon or krypton, boosts energy efficiency by nearly 100% over clear glass.”

Home Window Replacement Cost Estimates

During the summer, your air conditioner must work harder to cool hot air from sunny windows. Install ENERGY STAR®-qualified windows and use curtains and shade to give your air conditioner and energy bill a break.

If your home has single-pane windows, consider replacing them with double-pane windows with high-performance glass— low-e or spectrally selective coatings. In colder climates, select gas-filled windows with low-e coatings to reduce heat loss. In warmer climates, select windows with spectrally selective coatings to reduce heat gain.

Cold-Climate Windows Keep Heat In

Double-pane windows with low-e coating on the glass reflect heat back into the room during the winter months.

Warm-Climate Windows Keep Heat Out

In the summertime, the sun shining through your windows heats up the room. Windows with low-e coatings on the glass reflect some of the sunlight, keeping your rooms cooler.

$ Long-Term Savings Tip Installing high-performance windows will improve your home’s energy performance. While it may take many years for new windows to pay off in energy savings, the benefits of added comfort, improved aesthetics, and functionality can offset the cost.

Shopping Tips for Windows

  • Look for the ENERGY STAR® label.
  • Check with local utilities to see what rebates or other incentives are available for window replacement.
  • Choose high-performance windows that have at least two panes of glass and a low-e coating.
  • Choose a low U-factor for better insulation in colder climates; the U-factor is the rate at which a window, door, or skylight conducts non-solar heat flow.
  • Look for a low solar heat gain coefficient (SHGC)—this is a measure of solar radiation admitted through a window, door, or skylight. Low SHGCs reduce heat gain in warm climates.
  • Select windows with both low U- factors and low SHGCs to maximize energy savings in temperate climates with both cold and hot seasons.
  • Look for whole-unit U-factors and SHGCs, rather than center-of- glass (COG) U-factors and SHGCs. Whole-unit numbers more accurately reflect the energy performance of the entire product.
  • Have your windows installed by trained professionals according to manufacturer’s instructions; other- wise, your warranty may be void.
  • Consider windows with impact- resistant glass if you live along a coast or in areas with flying debris from storms.
