Cascade Gasket projectThis is a 50,000 square foot, retrofit roof project in Auburn wa.
The existing roof is a corrugated steel roof panel over a condensation blanket, fastened to 9 s-purlins, 5 on center.
The bottom layer, of new roof system ( white material) is an eps, dense foam, flute filler. This flute filler is manufactured to the exact profile of the existing metal roof. Two different sized pieces, perfectly fill the panel voids, flush to the top of the panel rib.
2nd layer is a 1 1/2, polyiso, dense foam, rigid insulation.
Insulation is fastened with 4x #14, fasteners, through 3, round, insulation plates.
This is the cool part. The black discs you see, in straight lines, 1 on center, are GAF, PVC clad welding plates. These discs/ plates are fastened with 4 3/4 purlin fasteners. The gray membrane (top layer) is a 60 ml. GAF PVC rolled over the rest of the system.
The Rhino Bond welder, locates the disc through the membrane and welds the membrane to the PVC clad plate, through the membrane. What!?!?!!
This is super cool, highly sophisticated technology and the perfect system for this application.
