What are people saying?

InSoFast, thanks for your help.

PS: We (two 73 year old men) installed 1,200SF of insulation on relatively tricky walls (lots of fitting) in 12 man hours. This was the first time for both men, and we simply watched your video for guidance. We plan to incrementally go through all our buildings with your product.

When I saw InSoFast EX 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.

InSoFast is ideal for both basement, retrofit and exterior applications. I found the product easy, fast and economical to use and recommend it first and above all other options to all my customers when the application is appropriate. Attached are photos of a job I did in 2010.

I just finished the walls with your InSoFast panels. I’m not a carpenter, I just found it very easy to work with. I just love it. I ordered some extra so I am going to use it on a floor in another room, too. I will be ordering more soon. Thanks for a great product.

Even simpler than I thought. It is a great product!

Your product is making the framing so much easier and faster for the guys, but also I think it was the best application given the condition of that side of the building!

Ed, a few months ago we talked. Since then I have done the install of your product in Perryopolis PA. Was very impressed. Two guys, 7 hours, 140 ft x 9 ft. No sweat.

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

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!
