polyethylene sheeting w/ Zip Huber

user-7502255 | Posted in GBA Pro Help on

I am building in western Colorado, we have low humidity, located in climate zone 5. I have 2×6 construction with Zip Huber sheathing with 1/2″ foam. My question is, should the interior wall have polyethylene sheeting? It is my understanding that the Zip product has a fluid applied membrane to protect against water and air infiltration. I am concerned that with polyethylene on the interior I will trap water vapor and have mold issues. I have inquired to Zip Huber, they did not respond. Thanks in advance.
