How Old Windows & Siding Increase Your Energy Bills?
Many homeowners don’t realize how much heating and cooling loss happens through the home’s exterior.
Most energy loss comes from:
- Drafty windows
- Weak or cracked siding
- Poor insulation
- Gaps, air leaks, and moisture issues
- Old wood frames
- Single-pane glass
According to the studies, up to 30% of a home’s energy loss can come from windows alone. Siding also plays a major role. The older materials often have low R-values. This means that they don’t insulate well. Upgrade to modern windows and insulated siding. This can lead to 15%–40% lower utility bills year-round.
