As we end our series about windows, we offer some easy, low-cost suggestions to make your home’s original windows more energy efficient.

  • Caulk around the window opening on the exterior.
  • Caulk around the window trim on the inside.
  • Add weather stripping to the window sash. There are many types of weather stripping to suit various window types, budgets, and needs.
  • Use a storm window or thermal panel.

Last but not least – a tip that requires neither tools nor supplies, and very little time. Check the lock!
Many people think the sash lock is primarily for security. It does help with security, but the lock’s most important job is to ensure that the meeting sash rails are held tightly together. A tight fit greatly reduces air infiltration.
