What type of insulation is generally recommended for attics?

In the context of attic insulation, various materials can be effective depending on specific needs and circumstances. All of the options listed—fiberglass batts, foam boards, and cellulose—are commonly recommended for attic insulation, each providing its own unique benefits.

Fiberglass batts are widely used due to their affordability and ease of installation. They offer good thermal resistance and can be placed between rafters or joists, helping to maintain comfortable temperatures within the home.

Foam boards are another effective option, particularly for attics with irregular spaces. They are highly efficient at preventing heat transfer and can be cut to fit various configurations, providing a continuous insulation layer that reduces thermal bridging.

Cellulose insulation, made from recycled paper products, is environmentally friendly and has a higher density than fiberglass, which can enhance its thermal performance. It is also effective at sealing gaps and providing soundproofing, contributing to a quieter living environment.

Using any or a combination of these insulation types will promote energy efficiency, reduce heating and cooling costs, and maintain a consistent temperature in the home. Therefore, the recommendation of "All of the above" is appropriate, as each type serves a distinct purpose and can be beneficial in different attic conditions or preferences.
