"All homes need a certain amount of fresh air," said Keith Saunders, a Home Comfort Specialist with Larry Janesky's Dr. Energy Saver of Connecticut. "But we usually find most homes, especially older homes, leak more than two to three times what they should."
Saunders should know. He teaches technicians at the country's largest energy conservation training center in Seymour.
That pink fiberglass insulation you've seen for years is not really that good, according to Saunders. Professionals like Dr. Energy Saver use cellulose insulation, which is basically ground up newspaper, and pump that into attics.
Of course, it's not just the top of the house. Drafts can come through any hole in the wall for light switches and outlets, and from the basement, too.
"So, if you're sitting up here and you feel cold air coming up from the basement or cold floors, it's oftentimes because the rim joist, the piece of wood that attaches to the foundation, is not insulated," Saunders said.
Spray foam insulation can solve that problem. Ironically, even your chimney can be making your house colder with gaps between it and the rest of the house.
