3 Types of Insulation for Your Home

Before deciding on insulation, it’s important to understand that different types of insulation are right for different applications. Different types of home insulation can change the temperature inside your house depending on the weather conditions outside.

We carry three of the most popular types of insulation: spray foam, cellulose and fiberglass. Each has distinct benefits.

Spray Foam Insulation in Eastern Washington


Spray foam insulation is intended to seal gaps and leaks inside existing walls, doors, windows and vents. It is a form of liquid polyurethane mixed and sprayed into the wall cavity, where it then expands and hardens into a solid foam.

It’s great to use in hard-to-reach areas such as attics, basements, interior walls and exterior walls.

Benefits of Spray Foam Insulation

Spray foam insulation was more popular in commercial buildings for many years. However, more and more homeowners are learning about the benefits of spray foam, and it has become a wise choice.

  • Enhances structural integrity: Spray foam adds strength to your home’s structure when applied to the walls, floors or ceilings.
  • Provides air and moisture barriers:Spray foam prevents air from seeping in or leaking out. It also helps prevent moisture from penetrating the home, keeping your home drier, healthier and more comfortable.
  • Has higher R-values: Spray foam comes in two constructions: open-cell foam or denser closed-cell foam. Closed-cell foam has the highest R-value of any insulation. At Intermountain West Insulation, we carry Homeseal N.A.I.S., an innovative closed-cell foam that is particularly good at stopping noise transfer.

Because spray foam must be applied carefully by a trained technician, we recommend you call our home insulation experts to handle your insulation installation!

Cellulose Insulation by Intermountain West Insulation

For the eco-minded homeowner looking for a more organic way to insulate your Eastern Washington home, cellulose insulation is the answer.

Cellulose insulation materials are mainly recycled paper, recycled newspapers, finely shredded recycled cardboard and other kinds of papers consisting of up to 80% recycled content. The loose-fill content is treated with chemicals to improve the protection of your home from moisture, heat and pests.

Benefits of Cellulose Insulation

  • Reduces waste:Cellulose insulation helps reduce the amount of paper and other recycled materials in our landfills.
  • Allows for easy installation:This type of material can be installed dry or wet and is blown in. No measurements, cutting or rolling out are needed with cellulose insulation.
  • Resists damage: Cellulose insulation is chemically treated to resist mold and fire and helps reduce the cost of energy in your home.

Batt & Blown-In Fiberglass Insulation in Eastern Washington


Fiberglass insulation is the most common form of insulation and is available in either loose-fill or batts. Fiberglass insulation is typically made of tiny glass fibers, although some are made of cotton, mineral wool, plastic fibers, or sand and recycled glass. It is mainly installed between joists, beams and studs.

Blown-in (loose-fill) fiberglass is very lightweight and is ideal for oddly shaped crevices or cavities. Batt fiberglass is available in rolls and pre-cut panels and is typically used for floors or walls.

Benefits of Fiberglass Insulation

  • Helps with noise reduction: Fiberglass insulation offers natural sound-dampening properties, which reduce the level of noise coming into your home and significantly reduce sound transmission in your home’s walls, ceilings and floors.
  • Is environmentally friendly: Because fiberglass insulation has significant recycled content, it helps reduce the impact on the environment.
  • Provides moisture resistance: Fiberglass insulation is nonflammable and protects your home from water damage.
