About this detail

An aluminum curb extending a minimum of fourteen inches high is mounted over an opening in the roof deck, with its curb flange fastened directly to the structural deck. Continuous rigid insulation wraps the curb assembly beneath a flashing membrane and continuous caulking at the joint. An ice insulated curb extension sits atop the base, enclosed by an aluminum cover. Exit seals accommodate conduits, pipes, and refrigerant lines ranging from one-quarter inch through fifteen inches outside diameter through the housing walls.
