Soy Based Spray Foam

“I bought some cans of [soy based foam] from home depot. I also bought some “Great Stuff” spray foam. I tested them side by side and the Biobased foam failed. It might have been the cold but it dried dry and crumbly. In comparison the Great Stuff dried like hard chewing gum…

Biobased foam crumbled when touched. This could be because it was cold when we installed it. But Great Stuff was installed exactly at the same time in the same environment…

This is very important because the foam is used to fill cracks. Cracks often expand and contract. The Great Stuff has an elasticity to it that the Biobased does not. Also, I forsee the Biobased foam deteriorating and becoming dust over time.”
