Attic Insulation - Poor Attic Insulation and Exposed Can Lights

Can lights are a major culprit of energy loss in homes, approximately 10 Cubic Feet per Minute (CFM) leak out of each can light in your home. If you're having a hard time imagining what 10CFM looks like, think of 10 basketballs flying out of just one can light every minute. Now multiply by how many can lights you have in your home. That's a lot of energy loss!
