Most residential homeowners understand that old windows are drafty. However, you may not realize that old windows may cost you far more in terms of heating, cooling, and electricity consumption. Old windows allow cool, inside air to escape in warmer months. They also permit warm air to be released during colder weather. These energy inefficiencies cause your HVAC system to overwork, dramatically increasing utility bills. Do new windows help with energy efficiency and improve a furnace or air conditioning unit’s performance? We explore the answer to this question by assessing the benefits of replacing old, drafty windows with new, airtight ones.
The Energy Savings Benefits Of Today’s Windows
Modern glass technology continues to evolve rapidly. Today, energy-efficient windows are coated with a material that reflects the sun’s UV rays (rather than allowing absorption). Additionally, many windows are double- or triple-pane, providing an even stronger barrier against air and moisture leaks.
Window manufacturers also incorporate Argon or Krypton in the space between panes to eliminate energy transfer through the glass. Window sashes are forged from long-lasting materials that seal tight. These innovations represent a 25-30% savings in residential heating and cooling (HVAC) energy use.
Do New Windows Help With Energy Efficiency
Yes. Energy efficiency experts recommend replacing old, drafty windows sooner rather than later. During your evaluation process, make sure to consider the following factors:
Gas Fills
- Gas fills are gases inserted inside insulated glass units (double- and triple-paned windows (a/k/a IGUs) to improve thermal efficiency. Most energy-efficient window spacers contain either Argon or Krypton.
Glazing
- Glazing is a putty-like substance that surrounds the glass outside a window. It seals the gap between the glass and the window frame, preventing air leaks and moisture intrusion, which improves energy efficiency.
Operation
- Most windows are fixed-pane, double-hung, gliding, casement, or bay (bow) style. When evaluating which alternative offers the highest energy efficiency, homeowners must consider the ideal window operation.
Window Frame
- The window frame matters significantly in determining its energy efficiency. Aluminum or metal frames are less energy-efficient than wood or composite frames, but fiberglass or vinyl frames offer the best thermal insulation.
