The Retro-Curb from Thybar Corp. is an insulated curb that allows for unrestricted positioning on standing-seam roofs. The company said they are designed to accommodate any slope for rooftop equipment. The curb has an oversized, flat, pre-punched base flange that can be cut out to allow for alignment with the seams on the roof. Company officials report that new, advanced laser technology enables Thybar to offer quality and competitively priced Retro-Curbs for metal buildings. Standard construction includes the 17-gauge AZ-55 galvalume with mitered and fully welded corners, formed in water diverter, and loose-cell caps to match most standing-seam configurations. All of this allows for a watertight installation, the company says.
