I am helping a buddy finish his project, and we have a few days before fishing season starts. The cabin in the upper Mat-Valley, and it's a 12X16. The crawl space is about 2 feet off the ground ,with the siding coming to the ground and an access hole to get under. The floor joice's are 2x6 on 16"centers. There's not alot of room to work, but can be done.
The problem is the past owners put regular insulation in between the joice's then capped it off with a plastic vapor barrier, I think it's 6mm, the thick stuff.The critters have made a Mega Mess of the whole thing, and his floor is really cold. All the material will be new. I was thinking that the vapor barrier should be on the warm side and not on the cold side, meaning that you should start with a vapor barrier first then insulate. We're scratching our heads trying to come up with a bullet proof setup.The crawl space pony walls are not insulated ,and theres no vapor barrier on the ground. Here's what we are thinking ,but sure could use some advice/help
Start by stapling foil bubble insulation to the underside of the subfloor, or thick plasticbetween the joices,then putting the insulation in and then possible stapling chicken wire to keep critters away, Or to start with the foil bubble wrap or plastic and then put about 6" of blue board, glued and foamed in on the edges. Thanks for the help and advice
