Home preservation specialist Bob Yapp doesn’t believe the myth that you can’t make an older home energy efficient.
He suggests thinking of an older home (or any home) as a chimney. Heat is rising through the building … as it does in a chimney.
The first and best defense is make sure your attic is insulated properly. And then, you should prevent the infiltration of cold air by eliminating openings where it can slip in through the home’s exterior envelope.
Plug leaks with caulk, weather stripping and expandable foam. Then you’ll prevent the chimney effect from robbing your older home of its energy efficiency.
