Green Tip: Smart Approaches to Stopping Air Leaks


Air leaks in a house are not created equal. Cracks or openings halfway up a house are not likely to leak much air at all, while leaks at the top and bottom of the structure have a big impact. Warm air rising in a heated building puts pressure on the highest ceiling. Any small openings around lights, fans or skylights are very important to seal. The warm air rising in the home (called stack effect) will suck in air at any openings at the foundation of the house. Make sure you seal along the top of the concrete foundation and around basement windows, as well as any piping or wiring penetrations in basement walls.
