Insulated a crawl space addition. This was the best way to go. Sealed and was enough to add 3” of insulation to all the walls. Very pleased how easy and fast it was.

I was very excited to try this product only to find it to be the most I’ve ever paid to make a mess.
In my opinion, this product should utilize professional equipment to disperse it. You can tell the foam does its job when applied as intended (and that’s the only reason I’m giving it 2 stars).
I prepped for this application as the directions instructed. During the entire experience I had the foam disperse evenly for maybe 30 seconds total, the rest came out in uneven globs and just made a mess. I covered maybe half of the intended surface area because of this.
I would not recommend this product to anybody. I have a feeling it wouldn’t have worked much better even if I was applying it to a vertical surface.
Just have a professional with proper equipment apply it or stay with batts.
