4 Types of Attic Insulation and Their Pros and Cons

April 22, 2025

Insulation is a key component to energy efficiency and indoor comfort. Insulation provides a barrier against heat flow, keeping warm air inside in the winter and cool air outside in the summer. Insulation comes in many forms, ranging from fiberglass batts to mineral wool. Its effectiveness is measured by its R-Value, with higher values indicating better resistance to heat transfer.

Keystone Premier Spray Foam Insulation depends on your needs, budget and energy efficiency goals. This article will explore 4 types of attic insulation and their pros and cons to help you make an informed decision.

Fiberglass batt insulation is one of the most common and affordable attic insulation options. It can be purchased at home improvement stores and is easy to install on your own. The main drawback is that it doesn’t react well to moisture and can lose its R-Value if it gets wet. It also doesn’t block noise as effectively as other insulation materials.

Cellulose insulation is made from recycled paper that’s treated with fire retardants and blown into attic spaces. It’s a green option that can help you meet your R-Value goal while also protecting against mold and rodents. However, it can produce a lot of dust during installation and removal. Additionally, it requires more maintenance than other insulation materials and can reduce its R-Value over time.

Spray foam insulation is another attic insulation option that can provide a more complete air barrier. It’s highly effective in preventing air leaks and is available in both open-cell and closed-cell varieties. It can be installed quickly and easily by professional installers. However, it’s important to work with a certified installer to ensure proper spray application and avoid damage to the attic or other areas of the home.
