Should the entire top plate along with the adjacent 2 inches of drywall be covered with open cell foam in my foam insulated attic?
I have posted a few questions on a totally open cell foamed Attic in Texas in hopes of findOmg the source of humidity in our attic. I have consulted with contractors but most are interested in full insulation work vs fill in type jobs. I appreciate all the advice that has been given.
The RH levels are going down but the humidity still remains higher during the day vs at night (55% day/51% at night).
I have noticed the top plate is exposed with insulation filling in the top corner where it meets the outside wall, but rarely is it totally covered. I am also able to see where the drywall and the top plate meet throughout 90% of the attic. Would this be done by design or would insulating this be best practice?
