Insulated curbs for metal buildings are custom-designed to accommodate any rooftop equipment and to conform to any roof pitch. They are fabricated using 14- and 18-gauge AZ-55 Galvalume material with welded construction, built-in diverter, and integral conforming notches for compatibility with Galvalume roof panels, and a water-tight seal. Factory-installed rigid insulation is included. Optional features include aluminum construction, extra height, noninsulated construction, fully welded curb to roof panel, double curb for rooftop units over 2,000 pounds, and separate retrofit cell caps.
