Types of Attic Insulation

316 Insulation is one of the most cost-effective ways to improve energy efficiency in your home or commercial building. However, it is important to consider the different types of attic insulation and how the material will perform in your space. It is also important to choose a professional installation company, especially for more expensive and advanced insulation options like spray foam, which require special equipment and training to install properly.

When it comes to attic insulation, the most common and budget-friendly option is fiberglass batt or roll insulation. It is available in pre-cut batts and long rolls, which can be easily fitted between the framing members (like joists and trusses) in your attic. Fiberglass is relatively inexpensive, doesn’t promote mold growth, and is resistant to fire. However, it does have a lower maximum R-value than other insulation materials and can decrease in effectiveness over time due to moisture damage or compression. Additionally, it is a favorite snack of raccoons!

DIY Attic Insulation: What Homeowners Need to Know

Loose-fill or blown-in insulation is another popular attic insulation choice. It is usually made from recycled paper, mineral wool or fiberglass and is blown into the attic using special equipment. This type of insulation is good at reducing heat loss or gain, and it is available in different R-values depending on your needs. It is also a great choice for eco-friendly homeowners or those who are concerned about the potential fire hazard of other insulation materials like cellulose.

Closed-cell spray foam is a more advanced option that is applied as a liquid and expands into place, filling all gaps, crevices and cracks. It is a great choice for attics as it is extremely resistant to heat and acts as both an air barrier and moisture vapor barrier, which helps prevent the penetration of water into your home. Spray foam is more expensive than other attic insulation types and must be installed by professionals due to its chemical handling.
