Thybar Corp.: Insulated Metal Building Curbs
A line of laser-cut, all-welded-construction, insulated, metal building curbs is available. According to the manufacturer, advanced laser technology offers the tightest tolerances and allows for a superior weld. Each curb is custom-designed to accommodate any rooftop equipment and to conform to any roof pitch. The curbs are fabricated using 14- and 18-gauge AZ-55 Galvalume® material with all-welded construction, built-in diverter, and integral conforming notches for complete compatibility with Galvalume roof panels and a watertight seal. Removable duct channels and insulated pans to accommodate duct locations are included. Standard features include built-in rib configuration, integral water-deflecting cricket, 3-inch attachment flanges, 10-inch minimum height, and factory-installed rigid insulation (1 ½-inch thick, 3-pound density) is included. A variety of optional features are available: extra height, uninsulated construction, double curb for rooftop units over 2,000 pounds, separate retrofit cell caps, and stainless steel or aluminum construction.
