MR-24 Panel Splice Support
On wider buildings, roof panels are placed end to end, creating a splice. Most manufacturers allow their splices to occur in midair—without direct structural support. Installers and other roof traffic—even the weight of snow—will push down on midair splices and cause strain on the splice, providing the opportunity for the splice to open. Butler prevents this by designing splice locations to occur directly over supporting steel while still allowing for thermal expansion and contraction of the splice.
