I have no experience with fish houses (not alot of ice fishing in MO) But I have quite alot of "spray" foam experience. Will the foam be exposed or do you fill a cavity in the floor? Be very careful you know the expansion rate of the product you are going to use, It can easily deform your bottom if you overfill it.

I have heard too many problems with people using this. It really expands!

I did the underside of my with 2" rigid last summer, works well and no need to put anything over it, just leave it exposed to the world. This stuff will last a lot longer than anything you could possibly put over it.

I did my 8x16 house for under $100. Insulation, glue (PL300) and I used some plumbing straps to secure the insulation in case it ever comes unglued. Don't need to see a piece fly out from underneath it while on the highway!

I think it depends on which type you would use. My dad used to work on Schwans trucks that were damaged and sometimes they would have to re-spray the inside of the cooler with the stuff. I have often thought that would work great, but also know it probably would not be cheap. That stuff is durable though. You may want to check with a local truck repair shop to see what they say. All refridgerated refer trailers use this stuff to insulate. If you find a great deal, let me know - I will post if I do as well.

Great Stuff makes a MINIMAL expanding spray foam. It might get expensive though. I would think it would take a lot of cans to do an entire floor.
