What it is

Product overview

KingSeam is Kingspan’s insulated standing-seam roof-panel system. The current US description identifies a vertical side seam with an integral batten, factory cutbacks for selected eave and end-lap conditions, multiple thicknesses, and accommodation for appropriately designed safety or fall-arrest systems.

It is a roof-envelope option where a standing-seam appearance and insulated panel construction are required. Slope, geometry, clips or fasteners, loads, supports, movement, cutbacks, penetrations, drainage, fire criteria, and fall-protection interfaces require current design information.
