Spray Foam Insulation vs. Fiberglass Insulation

If you’re building a new home or business and are looking at the options available to insulate it with, you may have encountered the option of spray foam. You may be wondering, “What makes spray foam insulation better than traditional fiberglass insulation? It’s all just insulation, right?”

Depending on your needs, spray foam insulation can offer vast advantages to fiberglass insulation.

Foam insulation vs. fiberglass:

Here are some of the most popular reasons people make the switch to spray foam insulation.

Energy Efficiency and Climate Control

Because traditional fiberglass insulation allows for air to escape, it makes it more expensive and less energy-efficient to heat or cool your business. Spray foam insulation does not allow air to escape, making it easier on both your wallet and the environment.


Fiberglass insulation needs to be replaced every 10 to 20 years, and that’s if your insulation stays dry. If this insulation becomes wet, it will need to be replaced immediately or you risk mold growth. This downtime for replacement is time that your business could be open and earning money. In contrast, spray foam insulation can last 80 years or more. In other words, a lifetime of insulation. No downtime, no recurring expenses for replacement.

Condensation Prevention

If you’re in business in the Pacific Northwest, you don’t need to be told about the significant levels of moisture in the air. With traditional fiberglass insulation, this moisture can become trapped allowing for mold and bacteria to grow. This could potentially create poor air quality conditions. Again if you’re fiberglass insulation gets wet, you’ll need to replace it. Spray foam insulation doesn’t retain water. With no water retention, there is no moisture buildup that leads to mold or allergens growing.
