Two vapor barriers in one wall
I have a new home under construction in very cold climate ( more than 8,000 heating degree days). Walls are insulated with 1and1/2 to 2 inches of closed cell foam and r13 batts in 6 inch walls. The insulation contractor has also placed plastic sheeting over the walls, stapled in place.
I told the buildert that the walls now can not breathe, but he says all of his recent houses have been done this way, and have been done this way by several different insulation contractors.
The home has a HRV and electric heat with wood stove backup.
Should I have them tear off the plastic? Any advice greatly appreciated.
