Floor Insulation - New Truck Build 92' P30
Hello, I'm new to the site, and have been getting a ton of great info so far from all of you! I'm embarking on my first catering/food truck build, and am hoping to get a few things figured out (I will get all photos etc. us ASAP).
Because of where I live I know I need to insulate the truck as best I can. My question is; have any of you ever put rigid foam insulation over your existing floor, before your plywood sub-floor? If so, did you then float your plywood sub-floor over the insulation, or did you secure it in some way?
Thank you in advance!
