Should I upgrade to double-pane windows?

If your home still has single-pane windows, upgrading to double-pane windows with low-E coating and argon gas fill can reduce energy loss by 25 to 50 percent. They also reduce outside noise, improve comfort near windows, and reduce condensation. Replacement windows cost $400 to $1,000 per window installed. The payback period is typically 10 to 20 years through energy savings alone, though comfort and home value add benefits.

Why It Matters

Single-pane windows are the weakest link in your home's thermal envelope. Upgrading improves comfort, reduces energy bills, and increases home value.
