Climate-Resilient Barrier Systems Training (CSN) The CSN exam digs into thermal bridging calculations, vapor permeability ratings, and hygrothermal modeling—material science concepts that trip up candidates expecting surface-level knowledge. You’ll navigate complex building envelope interactions where minor specification errors cascade into costly moisture problems, requiring precision beyond typical construction training.
