Vapor retarder paint doesn’t work with open-cell SPF – Reference?
On 10/29/15, there’s a nice response by Martin that says, basically, vapor retarder paint has been proven not to work. This was in response to the question, “Vapor barrier or vapor retarder paint on open-cell spray foam?”
The response mentions the proof came from Building Science, but I just can’t find the reference.
Would someone be able to direct me on where to find that? Many thanks in advance.
