Abstract
In “An evolution of knowledge,” February 2022 issue, I discussed NRCA’s research examining roofing-related problems with moisture in concrete roof decks. One area where NRCA considered additional research to be necessary was addressing the adequacy of vapor retarder adhesion to newly placed concrete roof decks. NRCA has since undertaken this research, which provides designers with some guidance for proper vapor retarder selection.
