How Attic Insulation Reduces the Burden on Air Conditioning Units
Attic insulation acts as a thermal shield that prevents outdoor heat from migrating into the living spaces of a home. During hot summer months, roof surfaces can reach temperatures exceeding 150 degrees Fahrenheit, causing the attic space below to become a massive heat reservoir. High quality insulation blocks this heat from radiating through the ceiling, which keeps the house cooler and allows the air conditioning unit to maintain a comfortable temperature with much less effort. By reducing the amount of heat entering the home, attic insulation directly lowers the cooling load on the mechanical system. This means the air conditioner does not have to run as often or for as long to achieve the desired thermostat setting. Experts in residential energy efficiency observe that homeowners with upgraded attic insulation barriers experience significantly shorter cooling cycles and lower utility bills, as the home retains its "coolness" for extended periods without mechanical inter...
