Morin, a Kingspan Group company, has introduced the SymmeTry Roof Series, a mechanically seamed structural roof system that is symmetrical and hydrostatic by design. A symmetrical metal roof system does not “lap” over an adjacent panel like standard asymmetrical panels. Symmetrical panels install side by side and have a mechanically seamed “cap” that has two beads of continuous butyl sealant, creating a watertight seam. MORIN’s SymmeTry Roof Series vertical panel legs range from 1 1/2 to 3 inches in height. Because they are bidirectional, the panels can be installed going left to right, right to left, and start from any point of the roof. Symmetrical panels are specified and installed to allow for unlimited thermal expansion and contraction, providing the advantage of installing panels up to 300 feet in length.
