Whether you’re building a new construction home or retrofitting an existing house, proper attic insulation is vital to your property’s comfort and energy efficiency. The Department of Energy recommends insulating to an R-30 rating or higher depending on your location.1 In addition, a poorly insulated attic can lead to ice dams and roof damage.

Common Signs You Need New Attic Insulation

Fiberglass batt insulation is a popular choice due to its low cost and ease of installation during new construction or renovations. It also offers high R-values and moisture resistance.

Blown-in or loose-fill insulation is made from tiny particles of fiberglass, cellulose, or mineral wool. A blowing machine spreads the material into your attic to fill gaps and cover surfaces evenly. It provides comprehensive coverage and is quick to install. However, it tends to settle over time, reducing its R-value. It can also absorb moisture, which can lead to mold and mildew.

Cotton insulation, or cellulose, is an eco-friendly option that’s made from shredded and treated recycled denim. It’s a greener alternative to fiberglass, and it’s softer and more breathable than other types of insulation. It’s a good choice for reducing sound transmission, and it’s treated with borate for fire resistance. It has a higher R-value than other types of insulation, but it’s not as durable or affordable.
