I am remodeling my bathroom with a new alcove tub. The short wall of the tub will be on an outside wall that currently has batt faced insulation. I will be using Kerdi over Durock on the three tub surround walls.

Is it necessary to change insulation to un-faced or cut slits in the faced insulation on this exterior wall.

I am concerned about creating a moisture sandwich between the kerdi and the faced insulation.

I am located in Southern NY by New York City.

Any help would be appreciated.

Thank you...

That's a good question, I'll be doing the same thing soon (albeit in Idaho, but we both get cold winters). My assumption would be it shouldn't matter a whole lot either way, because if you have moisture coming through the kerdi and durock then you have a problem that batt facing will neither help or harm. But I will defer to the wisdom of others...
