We have never used this type of insulation so I don't have personal experience. I do know that after Sandy hit the Jersey Shore some people were using it. However, we were told that if you are in a flood prone area and this stuff gets wet and it has to be removed to remove other damage.........it is a mess to deal with. I also did hear that it is hard once the house is built and drywall is installed to make sure you get the foam insulation in all parts of the walls because you can't see exactly what you are doing and they have to get it in all the bays between the studs. Here is a link to an article about the pros and cons...maybe it will help you decided for your situation.
