The Sarnafil RhinoBond system. This system uses Sarnafil’s proven PVC membrane, which is attached using RhinoBond’s advanced induction
Installation involved tearing off the built-up roof, replacing the decking, filling in some skylights, putting on a tapered insulation system and also filling the flutes of the metal roof with recovery board. Then the Sarnafil membrane was installed with RhinoBond induction welding. RhinoBond secures the membrane directly to specially coated plates, all without penetrating the roofing membrane. The result is a roofing system with improved wind performance that requires 25 to 50 percent fewer fasteners and plates.
In addition, since the fastening points are spread out across the roof deck in a grid pattern rather than concentrated in the seams of the membrane, the wind uplift load is distributed more evenly. The result is less point loading on each fastener, enabling the system to achieve higher wind ratings with fewer fasteners.
