length of vapor barrier in basement
I am finishing my basement...its about 7ft. below grade and I have just finished the framing. I am about to put the insulation in and then the vapor barrier (plastic sheeting) but I have been told two different ways in which to do this.!!!
One way is to take the vapor barrier right down to the concrete floor, and leave the top (by the ceiling) open.
The other way I was told was to leave about 1 - 2 inches between the end of the vapor barrier and the floor, and leave the top the same (open)....
Which way is correct? Thanks...
