Quick basement reno question before installing platon subfloor
I'm finishing my basement, and I'm about to put down the dimpled platon as the subfloor (with 4x8x3/4 T&G OSB on top), and have a quick question.
Would it be a good idea to put a vapour barrier that transitions from the floor to the wall? That is, have plastic sheeting that extends 6" under the platon, and runs 6" up the wall, sealed with PL Acousti-Seal?
Perimeter walls are poured foundation with 2" foam board (O-C Celfort 200) glued on (PL300). Once the floor is down, 2x4 stud walls will be framed and insulated against the foam board. Just wondering if it's a good idea to do something now - that's cheap & easy - to mitigate any potential moisture from migrating from the slab to the stud wall.
