Why is there moisture in the walls of my REMOTE wall construction?
Hello
I finally built my shop! The final construction is gyproc, furring, r15 batts, 2x6, osb 1/2, membrane blueskin vp160, 2 sheets of 4inch EPS foam (total of 8 inch), furring, siding.
I put Lunos for air exchanger.
But I noticed some issues lately. I checked the osb under the batts and in some areas, it is humid. I checked the humidity level of the room and it is high (around 60%).
For context, I started the glycol heating around 2 weeks ago and the air exchanger just 2 days ago. I am hoping to decrease the level of humidity with the Lunos and I will add a dehumidifier also.
My plan is as follow: I will try to decrease the humidity level of the room to an acceptable level (like 40%) and see the effect on the osb. If it is still a problem, I will remove the batts and live with only the foam insulation outside.
I would like to know what you think about all that.
All the best
David
