Retro-Curb from ThyCurb makes it easier to install roof curbs on standing seam metal roof systems.

Installation of roof curbs on metal buildings is made easier with the Retro-Curb from ThyCurb, Addison, Ill. These insulated curbs allow for unrestricted positioning on standing seam roof systems, and are custom designed to accommodate any roof slope for rooftop equipment. The curb has an oversized, flat, prepunched base flange that can be cut out to allow proper alignment with the seams on the roof.

Standard construction includes: #18 ga. AZ-55 "Galvalume," with mitered and fully welded corners; formed-in water diverter; and loose cell caps to match most standing seam configurations. Other standard features include a 11/2-in. 3# density fiberglass insulation, 8-in. minimum height, and T-bar reinforcing in sizes over 36 inches.
