Why Single-Pane Windows Struggle
Single-pane windows are common in older homes, especially in historic cities like New Orleans. While they add character, they lack insulation. According to the U.S. Department of Energy, windows account for 25–30% of residential heating and cooling energy use. With only one layer of glass, single-pane windows allow heat to pour in during summer and escape during winter, forcing your HVAC system to work overtime.
