Insulation in the attic optimizes a home’s energy efficiency and comfort while lowering monthly bills. In fact, some homeowners have reported savings as high as 32%.
While the spray foam insulation cost of a attic insulation project can seem high, many utility companies offer rebates and other incentives that reduce or offset the installation costs. Additionally, federal programs like the Weatherization Assistance Program help low-income households afford attic insulation. Check with your local ENERGY STAR Home Upgrade Partner to find out what incentives are available in your area.
Proper attic insulation reduces heating and cooling bills by slowing the transfer of heat between your living space and the attic, ensuring your HVAC system doesn’t work overtime to maintain a comfortable temperature. It also prevents moisture from forming on cold surfaces, including wood joists and roof sheathing. Moisture buildup can cause mold and mildew, reducing indoor air quality and putting strain on your HVAC system.
If you have existing attic insulation, it’s important to make sure it is in good condition and adequately sized. Use a ladder to inspect your attic floor and check the depth of your existing insulation. If it is shallow, consider adding more fiberglass batts or hiring a contractor to blow in loose-fill blown-in insulation. If you do choose to add additional insulation, ensure the unfaced side (without paper or foil moisture barrier) is placed against the attic joists.
Attic ventilation is essential to proper attic insulation performance. It helps your insulation perform better by expelling excess heat and moisture in the summer, while preventing condensation during winter. It can even protect against ice dam formation and help minimize water damage in the event of a leaky roof. Install a programmable smart vent, such as the GAF QuickConnect, to precisely control your attic ventilation. The app enables you to set the desired temperature and humidity triggers, and the connected vent will power on automatically whenever those conditions are met, ensuring efficient airflow at exactly the right time.
