The right attic insulation will keep the home more comfortable year-round, reduce the load on the heating and air conditioning systems, and pay for itself in energy savings over time. EnergyStar.gov will tell you the R-value (level of insulation) that’s recommended for your region.
If there’s no insulation at all (uncommon, but not unheard of), it’s a matter of sealing things up and selecting the best insulation for your needs. But what if the house already has insulation?
