Blown-In Cotton Insulation: A Guide For Homeowners

If your walls or attic are lacking in insulation, you have several options, including standard fiberglass batt insulation, spray foam, and an option that's quickly gaining popularity: blown-in cotton insulation. Here are some reasons why you, too, should consider going with blown-in cotton as your material of choice.

Cotton insulation is made from recycled and scrap materials.

Have you ever wondered what happens to all of the scrap material that's leftover from making blue jeans? It's used to make insulation! That's right – cotton blown-in insulation is made from denim scraps and pieces of recycled denim. You're not contributing to the production of any more materials when you choose blown-in cotton insulation. You're using up materials that might otherwise be sent to a landfill, and that's a great thing for the planet. If you're trying to meet green building standards, choosing recycled cotton insulation may help you achieve this goal.

Cotton insulation is safe.

If you have fiberglass insulation, you need to worry about inhaling the fibers or getting them on your skin. If pets or kids get into the fibgerlass thinking it looks warm and fuzzy, there's reason for concern. This is not an issue with blown-in cotton. Playing in it or touching it is no different than putting on a pair of jeans. It does not release any dangerous fibers into the air, so you won't have to wear a face mask if you ever do construction that exposes the insulation.

Blown-in cotton fills all of the nooks and crannies.

If you were to unroll fibgerglass batts between the floor joists in your attic or the wall joists in your walls, there would be some gaps between the rolls where they don't quite meet up. And over time, the batts might shrink and shift due to changes in moisture levels. But blown-in cotton completely fills the cavity it's blown into, so there are no big gaps to worry about air seeping through. If the insulation settles a bit with age, you can just have more blown in on top of it.

Blown-in cotton insulation absorbs sound.

Since it is more dense than fiberglass, blown-in cotton insulation does a better job of absorbing sound. Whether you live by a noisy highway or have neighbors who like to mow their lawns at 7 am on a Saturday, this is bound to make your home a more enjoyable place to be.
