Attic Insulation: Spray foam or Cellulose

Attic insulation is an important aspect of any home. Many homeowners don’t think about attic insulation, because it is a place they don’t see very often if at all. Just because you don’t see it on a daily basis, that doesn’t mean that it isn’t important to choose the very best products for it. There are several options to choose from for attic insulation. We are going to discuss two options for attic insulation: spray foam insulation and cellulose insulation.

Attic Insulation: Spray foam or Cellulose

  • Spray foam insulation – Spray foam insulation is an excellent insulator. There are two types of spray foam: closed cell and open cell. Closed cell has an R value of 6.5 and open cell has an R value of 3.6 per inch. The nice thing about spray foam is that it is sprayed so that it fills every crack and hole, no matter how tiny. Spray foam does tend to be more expensive, but it is the most effective for eliminating air leakage.
  • Cellulose insulation – Cellulose insulation is made from recycled cardboard. When professionally installed, it is mixed with water to help cut down on dust being kicked up in to the air. The R value of cellulose insulation is 3.5 per inch. This type of insulation is dense enough to stop air from traveling outside and reduces the chance of frost building up in your attic.
