Which insulation is best for my attic?

If you know you need insulation, but you just aren’t sure of what type, it’s time to do a little homework on the subject. When you hire professional insulation contractors in St. Louis, you will be given expert advice on which type is best for your unique situation. From spray foam and fiberglass batts to cellulose and loose-fill fiberglass, there are many choices out there. Let’s go over the pros and cons of each.

Blown In Insulation

Blown in insulation, made of cellulose or fiberglass, is quickly becoming the insulation of choice for both professionals and DIY homeowners. Also known as loose fill insulation, this type is comprised of loose particles that can be blown into an attic or wall. Because it fills all the air pockets, heating and cooling can’t escape. This is a great, all-over option that can help you control the comfort level in your home while slashing energy bills.

Pros of Blown In Insulation


  • Fills gaps efficiently
  • You can layer it for added protection.
  • It flows down around wall studs.
  • It’s flame resistant.
  • It’s non-toxic.

Cons of Blown In Insulation


  • Can get messy
  • Requires professional installation.
  • Can cause sagging of the ceiling.
  • Can lead to fungal growth.
  • Creates problems when wet.

Spray foam Insulation

With a high R-value and air sealing quality, spray foam insulation is available in open cell and closed cell foam. Because of its vapor-retarding qualities, this results in a pretty good savings on utility bills each year.

Pros of Spray Foam Insulation


  • Has a high R-value.
  • Is a very good air barrier because it hardens when dried.
  • It fills tight, hard-to-reach spots.
  • It can be applied to attic ceilings.
  • Features zero heat transfer through convection.

Cons of Spray Foam Insulation


  • They’re more expensive than other types.
  • They require professional application.
  • Can pose health risks due to chemicals in the spray foam.
  • Reduces the need for other home weatherizing tasks, like caulking.

Fiberglass Batts & Blanket Insulation

This is the most common insulation, available in rolls that are pre-sized to fit between joists and studs. Blankets and batts fiberglass insulation are both readily available and affordable, great for both new construction and gut-renovation projects. Batts usually come in 16 or 24 inches wide to fit between studs and four or eight feet tall to fit the height. This is most common in new construction and remodeling projects, as they fit snugly into the space between studs and joints.

Pros of Fiberglass Batts and Blankets Insulation


  • Does not contain harmful chemicals.
  • It’s fire-resistant.
  • They do well against burst pipe water damage.
  • Are the best option for DIY jobs.

Cons of Fiberglass Batts and Blankets Insulation


  • They don’t conform to odd or tight spaces.
  • They can leave gaps.
  • The material will compress with time.
  • Need to wear personal protection gear when working with fiberglass.
  • Can irritate your lungs and leave you feeling itchy.
