Retrofit Roof Drains Feature Integrated Vortex Breaker

OMG Hercules-Plus RetroDrainsOMG Roofing Products introduces a new line of retrofit roof drains called Hercules-Plus. The drains feature integrated vortex breaker technology. Vortex breaker technology helps improve drain performance by improving water removal off the roof.

According to the manufacturer, independent performance testing shows that Hercules-Plus RetroDrains provide up to 2.5 times greater flow capacity than original Hercules Drains without vortex breaker technology. Faster water flow off the roof also means that the drains get excessive weight off the roof faster. In addition, integrated vortex breaker technology greatly reduces the chugging effect that occurs when a vortex collapses, which can overload the plumbing system.

“Ponding water weighs approximately five pounds per inch per square foot. That means one-inch of water covering 20-square feet on the roof weighs 2,000 pounds,” said Dan Genovese, product manager with OMG Roofing. “That’s an additional ton of live load added to the building’s roof, and not entirely uncommon given the number of extreme weather events we’ve seen in the past few years. The new Hercules-Plus RetroDrains can get that water – and excessive weight – off the roof faster.”

Hercules-Plus RetroDrains are available in four sizes: 3 inches, 4 inches, 5 inches and 6 inches, and with an optional TPO or PVC coated flange for direct membrane attachment. Strainer domes are made of heavy-duty cast aluminum which will not rust for long life on the roof. In addition, the safety yellow powder coat makes the Hercules-Plus strainer domes highly visible to help minimize rooftop trip hazards.

Roof Edge Solution Offers Long-Term Structural and Thermal Performance

Eliminailer-TMetal-Era releases the Eliminailer-T, a heavy gauge aluminum extrusion that gets installed directly onto the building substrate in place of wood nailers to support increased long-term structural and thermal performance at the roof edge.

According to the manufacturer, more than half of recorded roof failures are attributed to the roof’s perimeter. Since 1980, Metal-Era has been addressing this issue with products designed to withstand severe weather conditions and engineered to exceed the latest code requirements.

“Wood is an organic material that starts its deterioration process the minute it is cut down. Pressure treated lumber introduces chemicals that can be corrosive. It’s a decision between a lesser of two risks,” said Scott Kittilstad, Vice President of Engineering. “We wanted to remove wood from the equation and provide an alternative that could perform and protect as well as our lineup of high performance roof edge products.”

Eliminailer-T is tested and meets requirements for FM 1-49. According to the manufacturer, an independent ANSI/SPRIK/FM 4435/ES-1 test at FM resulted in Eliminailer-T being able to withstand greater than 999 PSF at the corner region. As a result, Metal-Era supports Eliminailer-T with a 215 MPH Wind Warranty. The product can be installed installing up to 60 percent quicker than wood nailers, the manufacturer notes, and it also provides thermal benefits to the building that contribute to an improved system R-Value at the edge, up to 35 percent greater.

The product is currently available in four sizes to meet the majority of re-roof and new construction projects and can be shipped next day. Additional sizes are in development to further fulfill building requirements and an even broader scope of application scenarios, planned to be available in the coming months.

Reinforced EPDM Membrane Offers Tape-to-Tape Technology

JM EPDMJohns Manville unveils a new reinforced EPDM membrane sheet with tape-to-tape technology, JM EPDM R FIT. According to the manufacturer, the product is field tested and proven to speed up installation by as much as four times, leading to lower labor costs. The expense and time involved when using other membranes that require primer is also eliminated since no primer is needed, leading to lower installed costs. The initial bond between tape-to-tape membrane sheets has been measured to be up to 20 percent stronger compared to field-fabricated seams. The watertight seam is never exposed on the rooftop, so the risk of contamination during installation and post installation is minimal.

John Petruzzi, president of FPS Roofing, installed the new product and was impressed with how quickly the crew learned techniques to apply it. “We were sold when we saw for ourselves how fast the seam went together. We were hands-on with the product, the whole crew liked it, and I will continue to use it,” said Petruzzi.

JM EPDM R FIT enables a longer window of application time since the 10-foot-by-100-foot rolls are completely pre-taped. This means there is no waiting on primer to flash off to get to the next step. “Our field tests demonstrate that this product will go down up to four times faster than anything already on the market,” said John Quante, JM EPDM Product Manager, Roofing Systems. “The tape-to-tape creates a stronger initial bond, making the installation more robust from day one. This product evolution will allow roofers to bid more aggressively and no doubt architects and specifiers will see the benefits too.”

Portable RhinoBond Hand Welder Designed for Use in Tight Spaces

OMG Roofing Products introduces 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.
