What our customers are saying.

A neighbor is having her basement finished. I was laughing watching all the stuff they are lugging in for the project! It was SO handy to just slide the lightweight boxes down the stairs. I did all the EX Panels by myself in 10 hours. They have a good 6 guys working on it for days so far...suckers!


When I saw InSoFast I realized there was an opportunity here to help us meet energy codes and simplify installation...The thing I liked about [it] is that it's the insulation and the furring strips all in one piece. It adheres to the wall or it can be mechanically fastened to the wall. I think it's so simple anyone can do it.


What a pleasure the EX panels are! Having finished basements with both wood and metal stud framing before, I tried InSoFast EX in the hopes of increased performance over traditional methods, but I wasn't expecting the panels to be quite so fast to install. The system has been well thought out, and is a pleasure locking the panels together. Electrical and custom stereo wiring was as straightforward as all other aspects of the project -- from ordering through drywall install. Thank you.


InSoFast is one of the few products out there that is as easy to work with as it's advertised to be. It goes up quickly and is much less time consuming than framing a traditional wall...I highly recommend this product.


I could not believe how easy and effective this product is. I'm sixty-three years old and I was able to install InSoFast throughout my entire basement, large room, bathroom, hallway and mud room by myself in one day...Every one of the workers from electrician to drywaller and plumber could not get over the product and the service that went with it.


You have revolutionized basement finishing. InSoFast should have been invented 30 years ago!


You can't justify using stud framing and spray foam when InSoFast is available!


I didn't believe it was the same cost as framing and insulation, so I had to figure out the framing and insulation myself. It was virtually the same. I ordered the InSoFast had it shipped directly to my home. I didn't have to make multiple trips to the lumber yard or worry about loading framing lumber in my vehicle. By myself it took about 6 to 8 hrs to install the panels. InSoFast is an awesome product!
