Types of Attic Insulation
A well-insulated attic helps prevent heat loss that drives up energy bills. It also reduces humidity, stabilizes indoor temperatures, and minimizes outside noise.
Upgrading attic insulation is a simple, cost-effective home improvement that can dramatically improve energy efficiency and comfort. However, it is important to select a material that will meet the specific requirements of your home. For example, you may need a different R-value for humid climates.
There are four primary types of attic insulation: fiberglass, cellulose, mineral wool, and spray foam. Each has advantages and disadvantages. Here are some key points to keep in mind:
Fiberglass Quality Insulation is made from tiny strands of recycled glass and is available as blanket or batts that can be cut to fit attic space. It is non-combustible and does not release harmful gases during or after installation, which makes it a good choice for all regions of the country.
Cellulose insulation is an eco-friendly option that is a mixture of recycled paper treated with fire retardants and boric acid. It is blown into the attic, where it fills gaps and spaces more thoroughly than many other forms of insulation. It has a higher R-value than fiberglass and can help reduce air infiltration.

Mineral wool is a natural option that comes in sheets that can be attached to attic floors or walls. It can be a good solution for humid climates because it is resistant to mold and mildew growth. Rigid foam is available in panels or boards made from polystyrene, polyisocyanurate, or polyurethane. It can be installed over existing attic insulation or placed underneath a new roof, providing an airtight seal that can reduce energy waste.
