How Does Spray Foam Compare to Fiberglass?

The easiest way to compare any form of insulation is to place it side-by-side along what most of us know: fiberglass insulation. Compared to fiberglass, spray foams offer a lot of advantages.

Take a look at the following:

  1. Foam is more energy efficient
  2. The R-Value of closed cell foam is 300% that of fiberglass
  3. It’s estimated to last for 80 years
  4. It stops air and moisture from getting in
  5. Adds to the structural integrity of the building itself
  6. Foam spray frequently has a fire-retardant additive

It also costs quite a bit more, which is the biggest reason that it’s not being used as the gold standard in new construction these days.

If you’re looking to make your home more energy efficient then you’ll want to evaluate the costs. The savings of the higher R-value foams and longer lifespan of foams will more than make up for things over the lifetime of a building.

Basically, spray foam insulation is superior to standard fiberglass insulation in pretty much every way but it costs more.
