Portable RhinoBond Hand Welder Designed for Use in Tight Spaces

OMG Roofing Products has introduced the RhinoBond Hand Welder. Based on patented Sinch Technology, the portable RhinoBond Hand Welder is designed to help roofers weld RhinoBond Plates in tight spaces such as under raised rooftop equipment and on vertical surfaces. The ergonomically designed tool features a vibrating handle and an indicator light that lets roofers know when the tool is activated and when the weld cycle is complete. The base is recessed and features centering indicator lines to help users properly align the tool over installed RhinoBond Plates for optimum bonding and improved productivity.

The new tool weights just six pounds (2.7 kg), and operates on 110V and 220V power sources for global use. Each tool comes with three, eight-inch tall magnets, and a durable carrying case that protects the induction tool when not in use. Using a 12-gauge RhinoBond Power Cord (sold separately), the independent Hand Welder can be operated up to 100-feet (30 m) from the power source. A quick connect power cord pig-tail enables international users to quickly switch to the local plug configuration for global use (international pig-tails sold separately).

“Many roofers understand the tremendous productivity and performance benefits that RhinoBond offers,” said Web Shaffer, vice president of marketing for OMG. “In fact, some roofers have seen productivity rates increase by 30%. To enhance the systems’ overall productivity, we wanted to offer a solution that can be used everywhere on the roof, even in tight spaces. This new product makes that possible.”

The RhinoBond System is designed for use with TPO and PVC roofing membranes and approved by most roofing system manufacturers. The System uses advanced induction welding technology to bond roofing membranes directly to specially coated plates used to secure the insulation to the deck. The result is a roofing system with improved wind performance that requires fewer fasteners, plates, and seams, and zero penetrations of the new membrane. Since it was introduced in 1998, nearly 2.0 billion square feet (185 million square meters) of membrane has been installed with the RhinoBond System around the world.

Temporary Roof Membrane Offers Solution for Storm-Damaged Roofs

FiberTite Blue Roof FiberTite Roofing Systems introduces its new temporary roofing membrane, FiberTite Blue Roof. The FiberTite Blue Roof is a fabric-reinforced thermoplastic roof membrane designed for use on flat commercial and industrial roofs to offer a temporary solution for damaged roofs until permanent repairs can be made. The coating on the temporary roof membrane provides UV resistant performance for up to one year, as well as abrasion resistance. The fabric reinforcement provides both tear and puncture resistance. It is available in rolls that are 100 inches wide by 100 feet long. According to the manufacturer, it is ideal for temporary repair of damage caused by disastrous weather events, and it can also be used for tear-off areas or new construction until the final roof assembly can be installed.

The temporary membrane can be made watertight by conventional commercial hot-air weld seaming equipment. Alternate temporary seaming and sealing methods may include the use of FiberTite FTR-101 General Purpose Sealant, waterproofing caulk sealants, or adhesive tapes including duct tape. FiberTite accessories, such as molded pipe seals and corners, flashing membrane and FiberTite FTR-101 Sealant, can be used to temporarily seal roof penetrations.

Polyiso Sump Panel Arrives Ready to Install

Hunter Panels Target SumpTo provide contractors with a faster and easier way to create roof sumps, Hunter Panels introduces its new 4-foot-by-4-foot Target Sump.
