About this detail

An exterior insulation and finish system parapet wall assembly meets a roof deck at both the front and back conditions. The assembly consists of an approved substrate, expanded polystyrene insulation board adhered with Dryvit adhesive, and a base coat with embedded reinforcing mesh wrapped over the top of the framing or concrete. A metal cap flashing assembly is fastened to blocking above, while a Dryvit compatible sealant with a closed-cell backer rod interfaces with the separate roof flashing and counter flashing. Additional protective elements include Dryvit Aquaflash system detailing and surface preparation with Demandit or Color Prime where sealants are applied.
