A friend and myself are building a cabin in southern california. It doesn't snow often where it is located.

The cabin itself is setup on a post foundation and we are almost finished with the subfloor.

My question is, should we put a vapor barrier between the sub floor joists and the plywood sheets we put down? The front of the cabin is about 2 feet off the ground while the back of the cabin is about 6 feet off the ground.

If so, would something like tyvek work?


  • Is the cabin going to be conditioned (heated)? – Steven Feb 27 '15 at 20:44
  • @Steven it'll have a pot belly stove in it for when we are there and the walls will be insulated, but no HVAC if that is what you mean. – Ronnie Feb 27 '15 at 20:56
