Attic insulation is a double-duty system that keeps warm air in the winter and cool air in the summer, stabilizing indoor temperatures and reducing HVAC workloads and energy costs. Properly installed attic insulation can save homeowners between $1,200 and $2,700 per year in heating costs alone. This savings is even greater in the summer, when insulated attics help reduce cooling costs by keeping warm indoor air from escaping to hot outside air.

Different attic insulation materials have different R-values, a measure of how much heat it prevents from passing through it per inch. The Department of Energy recommends an R-value between 30 and 50 in most climate zones. Each material has its own unique benefits, so it’s important to consult a professional for advice on the best choice for your home.

Attic Insulation Done Right: Trust Vortex Insulation

Blown-in insulation, also known as loose-fill insulation, is made from small particles of fiberglass, cellulose, or mineral wool. It is installed with a special machine, filling gaps and nooks and crannies more thoroughly than batt insulation. It also offers an excellent sound barrier. Blown-in insulation has a high percentage of recycled content and is eco-friendly. However, it can be prone to moisture absorption if not properly sealed with a vapor barrier. It can also settle over time, reducing its R-value and increasing the need to add more.

Spray foam insulation is composed of polystyrene, polyisocyanurate, or polyurethane and comes in boards or panels. It has a high R-value per inch, acts as an air barrier, and seals leaks. It’s more expensive than other types, and professionals are required to install it due to its chemical handling and safety requirements.
