Insulating and Adding a Rainscreen on a Wall Without Siding
Hi there, I am located in Zone 6, Western NJ. I realized I have one wall with no siding – just #15 Felt over plywood over 2×4 studs w/ R11 fiberglass. The rest of the house has stucco – but they skipped this wall. As you might imagine this wall gets cold in the winter. You can clearly see the thermal transfer from the studs to the room on the IR camera. 🙂
Since there is no siding, I think it would be easy to add external foam. It looks like they just painted the felt. I assume I would need a rainscreen on top of the felt – is that right?
After that I am planning to attach 2 inch foam (wall is exactly 4×8 tall so that should be easy!) and then have someone do an EIFS finish. Does that make sense? Or is there any reason not to add the rainscreen? Thanks, Jay
