re: Insulation for Raised Houses

In my experience any insulation under house creates more problems then it’s worth, hides leaks until wood is rotten, hard to get termite contract on it, etc..... if you decide to do it, make sure to use open called foam, leave a good foot or two open around any water/drain pipe penetrations(especially toilets), and treat underneath with Borate before spraying foam. Pier and beam homes are supposed to breath and to ensure it’s long term health the more air flow underneath the better
