Conventional Roof Curbs (RC-2 to RC-6)
Factory-built, unitized roof curbs for mounting rooftop equipment and flashing it into the roof, in styles matched to the roof build-up: RC-2 for lightweight fill, tapered insulation or single-ply roofs, RC-3 for uninsulated decks, RC-4 for insulated decks, and uninsulated RC-5 and RC-6 versions. The RC-4 is made of 18 gauge galvanized steel with continuous welded corner seams, a raised built-in cant with mitered corners, an integral wood nailer (A style flush or B style overhang) and 1-1/2 in. of 3 lb. density fiberglass insulation, with a standard 9-1/2 in. height and a full base plate that takes up designed deck slope to give a level top.
