Question: Why is spray foam better than fiberglass?

Answer: Spray foam can air seal while fiberglass can't. Without a complete air seal, it cannot insulate properly. Have you ever looked at the fiberglass in your attic or in your basement rim joists (the area between the wall and floor above)? After a short period of time the fiberglass becomes dirty and dark looking. This is because the air is passing THROUGH it like a filter on your air conditioning system. That air will eventually find its way into your home. Also, fiberglass is very rarely installed correctly. This flaw leads to reduced initial R-values estimated at more than 28% less than the manufacturers' specifications.

Question: What is the difference between closed cell foam and open cell foam?

Answer: Closed cell spray foam is a rigid, medium density product that uses a blowing agent made by Honeywell called 245FA. Closed cell has a much better permeability rating than open cell. Closed is 0.95 perms at 1.5” thick and open cell is 15 perms at 2” thick. Closed cell has a much higher R-value at >6.3 per inch while open cell is 3.9 per inch. Closed cell foam expands 25x its liquid form and open cell expands 100x its liquid form. Both are applied as a liquid that expands, fills gaps, and cures into a plastic like material.

Question: Will spray foam insulation deteriorate over time?

Answer: No. Spray foam that is left undisturbed will stay intact, will not sag or settle, and will not deteriorate. This cannot be said for its counterpart fiberglass and cellulose. Every year that goes by, fiberglass and cellulose based insulations will lose R-value, settle or compress, and deteriorate which will leave your home exposed to thermal and moisture problems.

Question: Is spray foam insulation more expensive than fiberglass and cellulose?

Answer: Yes. The upfront cost of using spray foam insulation is higher than fiberglass and cellulose. However, when you add up the sustainability of foam, the reduced energy costs, and the overall comfort. The return on your investment can be as little as 4 years depending on the reduction in energy use after spray foam is applied.
