John writes from Williston, Vermont: "We have blown-in (loose) insulation in our attic that is about 6 to 8 inches thick. I am thinking this is not enough. You recommend about 15 inches of regular insulation on your web site "insulateyouratticnow.com". Do the same inches of insulation needed apply to loosefit type of insulation as it does to regular insulation?"

Answer: Additional inches of blown-in insulation maybe needed depending on the type used. I recommend contacting a contractor for more details.
