Insulation is an effective way to Spray foam insulation your energy costs by keeping hot air out in the winter and cool air out in the summer. It also helps prevent moisture in attics and contributes to healthy and comfortable living spaces. ENERGY STAR® offers helpful resources to help you properly insulate your attic and make your home more energy efficient.

This guide provides a step-by-step approach to attic insulation and energy management. It covers proper attic ventilation, air sealing and moisture control, as well as recommended insulation levels. It also addresses issues that may affect attic performance, such as roof leaks and pests.

It’s important to understand that the order in which work is performed impacts attic insulation results and long-term performance. Health, safety and durability issues should always be addressed before addressing energy efficiency issues. This guide outlines an order of work that prioritizes combustion safety, attic ventilation and durability and ensures that air sealing is completed prior to adding insulation.

The most popular attic insulation materials are fiberglass and cellulose. Both have R-values of about 2.2 to 2.7 per inch. Blown-in fiberglass is quicker to install and offers the flexibility of filling gaps and hard-to-reach areas. Cellulose is a denser material that can fill more gaps and offer better noise dampening. Either of these can be combined with radiant barriers to further reduce ceiling heat gains, especially in warm climates. Adding attic insulation helps to reduce energy consumption, which in turn conserves natural resources like oil and gas and limits greenhouse gas emissions that cause global warming.
