Types of Attic Insulation

Attic insulation is a great way to reduce energy waste and improve indoor comfort. It is an important part of any ENERGY STAR Home Upgrade and also provides significant financial benefits.

Keeping conditioned air inside your home rather than letting it escape through attic ceilings results in lower utility bills, improved comfort and a contribution to climate change mitigation efforts. Insulation can also help to prevent moisture issues and pest infestations in attics.

There are several different types of insulation and the ideal option for your home will depend on factors like the attic’s use, your climate zone, the amount of space in your attic and more. It’s important to consult with an experienced professional to make sure that you get the most efficient and cost-effective solution for your attic.

How Attic Insulation Improves Indoor Air Quality | A-1 Insulation Insight

Fiberglass batts are made from glass fibers and may be a good choice for attics in many homes. They are relatively inexpensive and easy to install. They are not moisture-resistant and can degrade over time if they become wet, so installing a vapor barrier in conjunction with fiberglass insulation is recommended.

Cellulose or mineral wool insulation is a more eco-friendly option that can be blown or sprayed into attics. It is fire-resistant and is more expensive than fiberglass, but it is also moisture-resistant.

Spray foam insulation is a high-end option that can be sprayed into attics or walls and provides excellent thermal resistance and a great air barrier. It is more costly than other types of insulation and may require professional installation.
