Without a doubt, this is one of the most common types of home renovation, and it's not hard to see why. Installing fiberglass insulation in the attic isn't an attractive home improvement, but it can help lower your utility bills. If the attic isn't properly insulated, it can be a problem during home inspections when it's time to sell. Insulation probably won't add much value to your home, but not having any type of insulation could be seen as a negative thing for buyers.
