Types of Attic Insulation

If you feel your home getting colder right after you turn off your heating system, or have astronomical energy bills every summer and winter, attic insulation could be the culprit. With a proper insulated attic, you’ll save money on your energy bills while maintaining an even temperature throughout the house year-round.

There are many types of attic insulation, with varying R-values and installation methods. When choosing a material, consider factors such as its R-value, climate, and how easily it can be installed in your attic.

Rigid foam insulation comes in sheets or boards made from polystyrene, polyisocyanurate, or other polyurethane materials. It’s easy to install, has a high R-value per inch of thickness, and resists moisture absorption and mold. However, it off-gases during and after installation and requires a well-ventilated attic.

Blown-in insulation, also known as loose-fill insulation, consists of small particles of fiberglass, cellulose, or mineral wool that are blown into your attic using a special machine. This type is quick to install and fills gaps and spaces more evenly than batt insulation, reducing heat loss and sound transmission. However, it can settle over time and absorb moisture, causing a risk of mold and mildew.
