When it Insulation Contractor to energy saving upgrades, attic insulation is one of the best investments you can make. It helps reduce the amount of energy it takes to heat and cool your home, cutting utility bills dramatically. It also extends the life of heating and cooling equipment. But how much you save depends on the type of insulation, the R-value (a measure of its insulating power), and local energy rates.

The Department of Energy recommends a minimum of R-30 insulation for most homes, although colder climates require more. The ENERGY STAR program offers rebates for attic insulation in many areas, as well as for air sealing and other improvements that increase energy efficiency.

There are three types of attic insulation: fiberglass batting, cellulose, and spray foam. The most common is fiberglass batting, which is made from recycled materials and is available in a variety of R-values. It’s inexpensive and easy to install, but it tends to attract moisture and is a favorite snack of raccoons. It’s also prone to settling, so you may need to top it up over time.

Why Attic Insulation is Key to a Comfortable Home – Insights from Spray Foam Genie

Cellulose attic insulation is made from recycled newspaper and other organic materials and has a higher R-value than fiberglass batts. It’s a good choice for colder climates because it provides extra warmth in the winter and keeps cool air from seeping into the house in the summer. It’s also less prone to settling than fiberglass and is more resistant to pests.
