Fiberglass batt insulation is one of the most common blown-in Insulation options. It is made from flexible fiberglass or mineral wool and comes in rolls or sheets that can be cut to fit between joists and studs in an attic space. The material is easy to install and offers cost-effective thermal and acoustic insulation, but it can settle over time, reducing its R-value.

Blown-in or loose-fill insulation is composed of small particles of fiberglass, cellulose, or rockwool that are blown into attics using a blowing machine. It provides comprehensive coverage and fills gaps better than batt insulation, but it can also settle over time, reducing its R-value. It is often made from recycled materials and can reduce noise transmission. It can absorb moisture, promoting mold and mildew, especially in humid climates.

Spray foam both air-seals and insulates in a single step. It is typically spot-applied as an air-sealing treatment prior to filling an attic with cellulose or fiberglass insulation, but it can be used in more generous quantities to eliminate the need for other types of attic insulation. It is also the most expensive attic insulation option, but it offers the best performance.
