Specifications Roof curbs shall be, prefabricated of PRIME MILL GALVALUME. AZ-55-ASTM-792 steel, minimum 18 gauge. Construction shall conform to commercial quality specifications, with fully mitered and welded corners, and shall include a formed-in integral water diverter. All welds shall be continuous, and shall be coated with one coat of aluminum colored urethane sealer. Curbs shall be internally reinforced, factory insulated, with 1 1/2" thick 3# density fiberglass insulation. Height shall be a minimum of 10" above the plane of the roof panel or as detailed. Top of all curbs for roof top equipment shall be level, with pitch built into curbs. Curbs for roof hatches, skylights and smoke hatches shall be constant height curbs following pitch of the roof unless specified otherwise. All curb flanges shall be prepunched at 3" centers with 1/4" holes, 1" in from outside edge of flanges. Roof curbs for Standing Seam roof panels with trapezoid seams and 12" rib screw down roof panels shall have separate cell caps for field location. Cell caps shall be of the same material as curbs and shall have flanges prepunched. Curbs shall be furnished with “ERECPAKS” which include: 2 1/2" triple bead tape mastic, urethane caulk, self-drill screws for flanges, self-tap screws for the sides or tops of the cell caps, and 3/4" tape mastic for the base flanges of the cell caps. Installation Instructions Installation instructions shall be shipped with all roof curbs. Roof curbs
shall be supported by a framing system, which fully supports all curb flanges
and the weight of the equipment being supported by the curb. Framing system
shall allow the curb to float during expansion and contraction of the roof panel.
Roof curb and frame shall not pin the roof panel to the building structural
system. Roof top equipment on Standing Seam roofs, which exceeds 2000 lbs.,
shall be supported on a “Structural Double Curb” which has an inner
curb to transfer the equipment weight to the building structural system and
an outer curb which flashes to the inner curb, preventing the unit from pinning
the roof panel to the structural system. The double curb shall also be used
for screw down roof panel with units exceeding 2500 lbs.
