A properly insulated attic is one of the best home energy upgrades you can make to reduce heating and cooling costs. The Department of Energy recommends a minimum R-38 insulation level. However, over 90% of homes are under-insulated. In addition to wasting money, poorly-insulated attics allow cold air to seep into your home, leading to uncomfortable temperatures and increasing your energy bills.

Keystone Premier Spray Foam Insulation can be installed in a number of ways. Fiberglass rolls are the easiest to install and can be purchased at any home improvement store. When installing, ensure that the fiberglass is unfaced and not treated with a vapor retarder. It’s important to lay the second layer of roll insulation in a perpendicular direction to the first, avoiding any gaps and seams. It’s also important to keep all insulation at least 3 inches away from recessed “can” lights, unless they are rated IC (Insulated Ceiling).

Blown-in Insulation

Loose-fill insulation such as fiberglass or cellulose is sprayed into your attic with a blowing machine. It is a more expensive option but provides better coverage and R-value than fiberglass batts alone. It can also be a good choice for older homes with fewer obstructions in the attic space. However, blown-in insulation can settle over time, reducing its R-value, and moisture absorption can lead to mold and mildew. It also requires professional installation.

Spray foam insulation is a two-part liquid that expands into a foam upon curing. It can be applied to any attic surface and fills all cracks, holes and crevices. It is available in open- and closed-cell, with closed-cell offering more resistance to moisture and a higher R-value. It’s also more expensive but it does seal air leaks in your attic, making your house more energy-efficient.
