Raised Floor on Piles Insulation in 4A and Floodplain
Building a project in zone 4A that is an exposed wood frame raised floor on piles, in a flood plain. I should also note, that we can’t add a crawlspace or any other obstructions besides the piles due to township regulations. I’ve seen plenty of information on how to insulate for a hot humid climate/flood zone (Lousiana) but can’t find anything directly related to our climate zone, which also requires the floor to be min R30. Trying to decide between flush framing and dropped beam structure, but would likely have 2×12 framing. What is the best way to insulate and air seal in order to make sure this assembly works and can dry correctly?
