Attic crawl spaces and knee-walls
If you have a 1.5 or two-story home with slanted ceiling chances are you have knee-wall spaces, also called crawls spaces.  As originally constructed these homes have huge areas of energy loss.  Read how we air seal and insulate knee-wall spaces.

Can I add new insulation on old?
Absolutely!  As energy costs increase so does the recommended level of insulation.  Adding new insulation on top of the older fiberglass, rock wool, vermiculite or cellulose is  the way to go.  What type of insulation should you add?  Read about the fiberglass vs cellulose debate.

How much insulation do I need?
In zone 6 the final attic R-value should be between R49 and R60.  This requires approximately 15 inches of cellulose or 20 inches of fiberglass. You can view the full details at the US Energy Star web site: Recommended Levels of Insulation
