What is the maximum panel length available and how are long runs from ridge to eave accommodated?
The typical maximum length is 50’. Endlaps are required for longer runs from ridge to eave. Endlaps consist of an extension of the top metal skin of the panel and butt joining of the foam core and the bottom skin. The end of each panel is supported by the roof structure. The lapped faces are sealed with specially designed sealants and fasteners to create a gasket-type joint that effectively resists water penetration.
