Image Text: That chill in your house isn’t a spooky ghost – it could just be signs of a poorly insulated home. Most existing homes are not insulated as well as they should be. If you want to substantially reduce energy costs and decrease the amount of energy required for heating your home, attic insulation is a great place to start. Attics need to be insulated to the highest R-value because of the critical location in the flow pattern of air exchange. A well-insulated attic must be adequately ventilated to prevent moisture accumulation and promote proper air movement throughout your home and increase the efficiency of your HVAC system.
