Closed cell spray foam insulation could be a perfect fit for your project, but first, you want to learn a little more about it. You've come to the right place -- in this episode of Foam University, the Brainiac explains exactly what closed cell spray foam is, what it's made of, and which projects are the best fit.

0:00 - Intro
0:26 - Closed cell spray foam is a low-expanding, rigid spray foam that creates an air seal and has a high R-Value.
0:35 - Closed cell spray foam insulation is a great fit for pole barns, vans, tiny homes, and commercial buildings.
1:08 - Closed cell rejects bulk water, and it doesn't absorb moisture.
1:19 - The benefits of closed cell spray foam include that it's durable and can be left exposed, it's mold-resistant, and it has a low expansion rate.
1:52 - The spray foam is made from an "A" side, which is the isocyanates, and a "B" side that contains resins, blowing agents, flame retardants, and catalysts.
2:12 - Make sure to ask your insulation contractor whether the closed cell spray foam they offer has low VOCs, is Class One Fire-Rated, and what the reoccupancy time is.
2:25 - There is some prep work before the closed cell spray foam insulation is applied to the cavities.
