12 Jun Spray Foam vs. Fiberglass Blown-in Insulation: Pros and Cons
Heating and cooling bills can soar when you have air leaks in your attic or need new insulation. If you want to save money on your energy bills, upgrading your attic insulation will make a huge difference. Modern insulation materials like spray foam and blown-in fiberglass last a long time and greatly improve your home’s efficiency. And if you have questions about which type is best for your home, the experts at Energy Saving Pros can help.
Spray Foam vs. Fiberglass Blown-in Insulation
The main difference between spray foam insulation and blown-in fiberglass insulation lies in their materials. Spray foam is a liquid chemical, while fiberglass is made from 20% to 30% recycled glass. Because spray foam releases environmental toxins, fiberglass is definitely the greener choice. Fiberglass also lasts at least 20 years longer, and does not shrink or degrade over time.
Attic Insulation: Foam vs. Fiberglass
Although their materials are very different, spray foam and blown-in fiberglass insulation have very similar effects. Both types offer excellent attic insulation and both types will resist fire, moisture, and mold. Spray foam insulation has the highest R-value, but it comes at a cost—you can achieve the same outcome with blown-in fiberglass for a much lower price.
Pros and Cons of Spray Foam vs. Blown-in Fiberglass
- Provides an airtight seal
- Lasts up to 80 years, but shrinks over time
- Has a higher R-value, but a higher cost as well
- Difficult to install properly
