Hi,
For basement insulation in my area it seems that XPS is difficult to find in 3", so is there any problem with adhering 2" to the wall then 1" board to that?
The final layer will then be taped and sealed at the bottom.
I figure it may be easier to do that versus roxul in the joist bays?
thoughts?
