Attic insulation is one of the best energy-saving home upgrades that you can make. It creates a dead air space between your attic rafters, keeping warm air from escaping in winter and cool air from seeping into the house during summer. In addition, it reduces your HVAC workload and lowers your energy bills.

A good attic insulation should have a high R-value rating. This refers to how well the material prevents heat from passing through it, per inch. The Department of Energy recommends that you choose a minimum of R-30 for your attic, though homeowners in very cold climates may need a higher R-value. The type of attic insulation you select will also depend on your budget and installation needs.

Blanket or batt commercial insulation is commonly made from fiberglass and other materials like cellulose and mineral wool. This type of attic insulation is available in blankets or sheets, which can be easily affixed to unfinished areas of your attic. It’s a popular DIY option, but it can be problematic if it’s not installed properly. Fiberglass batting can be susceptible to moisture, and it’s a favorite snack of raccoons. It can also emit harmful gases during and after installation, requiring a vapor barrier to be installed along with it.

Signs Your Attic Needs an Insulation Upgrade

Rigid foam insulation is a more expensive option, but it can offer the highest R-value of any attic insulation. It comes in panels or boards of polystyrene, polyisocyanurate, or polyurethane. It isn’t as easy to install as batt insulation, but it can be a good option for a homeowner who is comfortable doing DIY projects. It can also help with soundproofing, but it’s important to note that a vapor barrier is necessary for the material to work effectively.
