On our previous blog, we discussed the basic information you need to know about attic insulation. Today, let’s focus on the different types so you can determine which one will work best for your budget and needs.
Blanket Insulation
Blanket insulation is available as batts or rolls and is the easiest DIY insulation material. It’s available in fiberglass, mineral wool, plastic fibers, and natural fibers. This type of insulation is ideal for attics with standard spaced beams and joists and very few obstructions.
Batts must be carefully trimmed to fit snugly around vents to retain their R-value effectiveness. Pricing can vary based on thickness and material, but it’s generally 0.15 to 0.50 cents per square foot. You can expect an R-value of 3.1 to 3.8 per inch. (Source: PopularMechanics)
Loose Fill
Insulation fibers are packaged in bags and blown in place to the desired depth and density using special machinery you can rent from a home center. You can pour the fill in place and spread it manually, but the process is much more labor-intensive and the results won’t be nearly as good.
It works best for:
– Attics with irregular or nonstandard joist spacing
– Attics with lots of obstructions and penetrations to work around
– Attics where there is existing insulation to be topped, since it fills gaps and joints well
– Low-clearance attics with limited headroom for maneuvering during installation

Spray Foam
Spray foam insulation is the most expensive insulation, and it is available in open cell and closed cell options. Open cell is the less expensive option; however, it does not provide any vapor barrier. Closed cell, on the other hand, is more dense, and it provides an excellent barrier against air and water. Spray foam insulation sticks to whatever surface you spray it to; so, your installer can apply insulation to the ceiling in addition to the rest of your attic for added protection. Spray foam products are most easily installed in newly constructed homes.
– Best for: Insulating against noise, new construction, outdoor applications (closed cell)
– R-Value per inch: 5 – 6
– Average cost: $2,208 (Source: HomeAdvisor)
