Energy Savings

Windows are usually the largest source of heat loss in your home, taking up 30% of total energy consumption. The EPA’s Energy Star Buildings Manual says, “windows almost always represent the largest source of unwanted heat loss and heat gain in buildings.”

Many of the homes built in the Atlanta area have low cost wood-framed with single glass panes that let the cold air out in the summer and heat out in the winter. Even many of the replacement windows homeowners typically focus on are of low cost rather than high performance.
