Spray Foam vs. Cellulose Insulation: Which Is Best for Your Home?

Are you tired of rising heating and cooling bills or uneven temperatures and comfort levels in your Manchester, VT or Keene, NH home? Upgrading your home’s insulation can have a dramatic effect on your HVAC system’s efficiency, saving you money, and you’ll provide year-round, whole home comfort for you and your family.

But which insulation material is going to provide the most benefit to your house? Today, let’s examine the pros and cons of two popular insulation types: spray foam and cellulose.

The Pros and Cons of Spray Foam Insulation

Spray foam insulation is a polyurethane foam that is often “sprayed” (hence the name) onto the areas of your home that you’re looking to protect from heat losses and gains. As it dries, it hardens into a protective coating that not only offers superior R-value and insulating properties, but acts as a moisture and air barrier as well.


  • High R-value

  • Protects against air and water

  • Great for sealing and insulating hard to reach or awkward shaped areas


  • Higher cost

  • Less environmentally friendly than other insulation types

While spray foam can be used in a number of different areas of your home, you’ll often see it used for basement insulation (because of the concern over moisture). Another common application is installing spray foam onto the roofline for attic insulation.

The Pros and Cons of Cellulose Insulation

Cellulose insulation is an eco-friendly insulation made primarily out of recycled newspaper that’s been treated to be fire and mold resistant. Cellulose can be installed in two ways: as dense packed insulation in existing walls, or as loose fill insulation spread over attic floors.


  • Environmentally friendly

  • Inexpensive

  • Fire-resistant


  • Vulnerable to moisture damage

  • Can “settle” and lose R-value over time
