Keystone Premier Spray Foam Insulation to an attic is the most economical way to weatherize your home. It’s also a project that most homeowners can handle themselves, especially if the attic is easily accessible and you’re comfortable working in confined spaces.
Before you start adding insulation, take a look at what’s already there and determine its R-value, which measures how well it resists heat flow. R-values are calculated for different climate zones, and the higher the number, the better the insulating power. If your current attic insulation isn’t up to R-38, you can add additional blown in insulation to reach that level.
Top Benefits of Attic Insulation Every Homeowner Should Know
You can add loose-fill fiberglass or cellulose, or rolls of fiberglass batts that have a built-in vapor barrier. Whichever you choose, it should be “unfaced,” meaning it doesn’t have a paper or foil backing, and it must be installed over any existing insulation. If you’re adding a second layer, install it perpendicular to the first to avoid creating air pockets.
Don’t forget to seal air leaks between the attic and living spaces, which can diminish your insulation’s effectiveness. Leaks typically occur around windows, ductwork, pipes and vents, but can be sealed with caulk, spray foam or weather-stripping.
Remember to wear protective gear during the insulation installation process. Fiberglass insulation can irritate your skin and lungs, so use long sleeves, pants, goggles and a dust mask or respirator. It’s also important to lay down temporary plywood flooring instead of standing directly on the joists, and make sure there’s plenty of lighting in the attic.
