Adding attic insulation is one of the most effective ways to make your home more energy efficient. It keeps heat in during the winter and cool air in during the summer, reducing HVAC workload and energy bills. It also reduces noise and improves indoor comfort.

Erawl space encapsulation are five primary types of attic insulation, and each type is ideal for specific situations and climates. Some are DIY-friendly, while others require the expertise of a professional installer.

Blown-in cellulose insulation is made from recycled materials such as paper, cardboard, and wood products and is flame-resistant thanks to boric acid applied during production. It offers a slightly lower R-value than spray foam, but it is more environmentally friendly. It also helps prevent the buildup of moisture in the attic, which is a common cause of attic mold.

Why Attic Insulation Is Essential for Energy Efficiency

Fiberglass batt insulation, also known as blanket or batt insulation, is a popular DIY option because it’s easy to install and affordable. It’s suitable for standard stud and joist spacing, and it’s often used in conjunction with a vapor barrier. However, fiberglass is moisture-prone and a favorite snack for raccoons.

Mineral wool and rigid foam boards both offer high R-values, and they’re moisture resistant. They’re usually installed in the attic with a plywood backing and can be used in combination with a vapor barrier or a ventilation system.

Spray foam insulation requires a professional installer to properly apply it. It’s a fast-acting product that expands to fill gaps, but it can be dangerous to work with because of its highly volatile chemicals. Protective equipment is required, including a mask, eye protection, and gloves. It’s best to start with a test application in an inconspicuous area to ensure proper safety procedures.
