Works extremely well, surpassed my expectations and hopes. Expands a lot, and with these extra large cans, there's a lot of spray foam to work with! Very easy to use, cures quickly, little to no smell, and an incredible value for the money.Great insulating properties and the color blends in well so you don't notice it.Buying in bulk like this is the only way to go, and this is a superior product. I will definitely be purchasing again!

I was on the spray foam insulation product and picked a different option on that product in order to get just two cans so I could test it out. Unfortunately I didn’t see that this changed the product from spray insulation to gap filler. Wasted money.

Nice large cans of foam. Sets up pretty quickly, no holes/voids at all.I think this is the second time to order this brand, and there's more in my cart.

I purchased this in August 2024 but didn't use it until early October. From the first bit of application it was obvious something was wrong. It never set up properly, was a mixture of shades of white and browns no matter how much I shook it, and made a real mess while applying as it sagged horribly--it was like applying soft whipped cream. Turns it it had a pull date of April 2024--four months prior to my purchasing it. The website says it has a 12 month shelf life. It was applied by someone with extensive experience with PU foam...and he'd never seen anything like it. Total mess, total waste of time and money.

Expansion in cracks could be better. Thought this was suppose to be better than normal brand.

Let me just say this… if you are used to the old school spray foam from even a decade ago… this stuff is 25x better and a little goes a LONG way. It’s easy to apply, but do not think this stuff doesn’t expand, because 30 minutes later you will see what it can do! I side this to fill various gaps ranging from 2-8 inches and it works fantastic. I will definitely purchase this again.
