Exterior foam detail for soffit/J Channel
Greetings!
I’ve been reading for a while but have not posted. The information contained has been valuable.
Background:
The house that I am working on was built in the 1950’s and is a stick framing with vinyl siding. The house at some point had 1/2″ exterior foam applied. We are located in Pennsylvania. I added overhangs and gable ladders to provide an overhang. My questions are these:
My question today is:
When replacing the exterior foam on the house, I am unsure of where to terminate the foam. I will be doing a soffit under the overhangs all the way around the house. I will be using aluminum J Channel to secure the soffit on the house side. Should I mount the J or F Channel on top of the 1/2″ foam or should I terminate the foam at the J Channel on the wall? Attached is a wall detail.

i would run the foam up past the j channel location. mostly because if your foam is not cut on a perfect line you will more than likely be able to notice it as the channel will wave up and down with the uneven cut.
