Hello i have built a cabin about 2 years ago. ( knowing then alot less then i know now ) and just in general i am wondering if what i have done will be sufficiant for the long haul.
Basically i have a raised floor on pier and beams . The layers of the floor go as such from outside ( bottom) to inside ( top)
-2" foam board insulation with gaps around edges sprayfoamed
-r20 rockwool insulation in between floor joists
- layer of subfloor (1"×8"x 12' pine boards) running E to W
- 6 mil poly barrier over entire floor inside ( but only to the egdes of the walls where its tied into the 6 mil on the interior walls )
- then a second layer of 1"x8"x12' pine boards running N to S. Used as my interior flooring .
I cant help but think something may have been done wrong here any help or suggestions will be appreciated.
