Customer Reviews
Good quality, quick delivery
I ordered a few boxes of the Rockwool Comfortbatt for a basement project. The website was easy to navigate and placing the order was straightforward. It shipped pretty fast, got to me in about 4 days which was nice. The insulation itself was good quality, easy to cut and fit. Overall, a solid experience.
Decent prices for spray foam
I needed a spray foam kit for a small garage job and was trying to spend smart. Insulation4US had some competitive prices, especially since I was buying a couple of kits. I didn't see a first-time buyer discount, but the overall cost was still better than what I found locally. Paid for itself pretty quick.

Hey, thinking of getting some rigid foam board for a basement project. Does Insulation4US actually deliver to residential addresses? And what's the typical wait time for something like that, I'm in Chicago.
