Kemper System Celebrates 60 Years Building Envelope Solutions

Kemper System is celebrating 60 years of success and building on its strengths to address the entire Building Envelope.

“Kemper System was built on novel approaches to challenges, product quality and customer service, and those continue to be the bedrock of our relationships,” says Richard Doornink, president and managing director of Kemper System America Inc. “Our role is to help architects and other specifiers find the balance between often competing goals on projects across the Building Envelope. The right technology makes those choices easier,” he states.

Today, the company offers an expanded range of Building Envelope solutions to protect against weather, preserve the integrity of surfaces and enhance the comfort and value of public buildings and commercial real estate.

As part of the company’s expansion efforts, Kemper System America acquired STS Coatings Inc. in December along with four flagship brands, and is exploring additional technologies to build its portfolio, Doornink stated. In addition to the technologies from STS Coatings, this encompasses Kemperol reinforced membrane systems, and COLEAN durable coatings systems for protecting surfaces prone to heavy wear.

Technology Roots

Kemper System traces its roots to polymer chemist Heinz B. Kemper, Ph.D., who founded the original company in 1957 after developing a roofing system using a cold liquid-applied resin reinforced with polyester fleece. After conducting over 200 trials, in 1969 he patented Kemperol V210, a reinforced membrane system which proved to be effective, and could stand up to sun, rain, snow, ice and standing water longer term.

That led to further advances in cold, liquid-applied membranes including the company’s flagship solvent-free and odor-free Kemperol 2K PUR membrane system, launched in the U.S. in 1999, and more recently, Kemperol 022 reinforced waterproofing system for indoor tile, and fire-rated Cool Roof systems – the odor-free Kemperol Reflect 2K FR and fast-curing Kemperol AC Speed FR.

Today, Kemper System products protect surfaces under a range of climatic conditions spanning: new and existing roofs, white roofs, green roofs, blue roofs, interior and below-grade waterproofing, parking garages, balconies, terraces, plazas and historic restorations. In North America, Kemperol membrane systems protect projects including the Empire State Building in New York, CN Tower in Toronto and Marketplace Tower in Seattle.

Kemper System America Inc. is a wholly owned subsidiary of Kemper System GmbH & Co. (KG | Holländische Straße 32-36 | D-34246 Vellmar). Kemper System is part of the IBG Group of companies, a mid-sized industrial holding company with more than 50 sales and distribution sites, as well as production companies all over the world.

OMG RhinoBond Projects Are Being Completed Across Europe

OMG Roofing’s RhinoBond System has left marks across Europe with more than 125 completed projects and more in the pipeline. Collectively, these projects represent more than 300,000 square meters (3.2 million square feet) of single-ply roofing.

“In last two years, the RhinoBond System has started to take off across Europe, as more roofing contractors have seen the roof performance benefits that the system can offer,” states Web Shaffer, vice president of marketing for OMG Roofing Products. “We have completed projects across Europe and we are expanding to new countries in the region, most recently, into South East Europe.”

RhinoBond is a method for installing thermoplastic and now also clean EPDM membrane. The system consists of a stand-up induction welding tool and magnetic cooling clamps. Contractors install roofing insulation using fasteners and specially coated plates designed specifically for the type of membrane being installed – PVC, TPO or Clean EPDM. Each plate is then bonded to the roof membrane installed over the top with the RhinoBond plate welding tool. The result is a roofing system that can provide wind performance with fewer fasteners, fewer membrane seams and zero penetrations of the new membrane.

The RhinoBond System is approved for use in Europe by many roof system providers, including Bauder, Carlisle/Hertalan, Danosa, Fatra, FDT, Firestone, GAF, IcoPal, IKO, Renolit, Sika, Siplast, and Soprema/Flag.

Headquartered in Agawam, Mass., OMG Roofing Products is a supplier of commercial roofing products including specialty fasteners, insulation adhesives, roof drains, pipe supports, emergency roof repair tape as well as productivity tools such as RhinoBond. The company’s focus is delivering products and services that improve contractor productivity and enhance roof system performance.

Fleece-Backed Thermoplastic Membrane Exceeds Weathering Tests

KEE-Stone FB 60 fleece-backed thermoplastic membrane stands up agains harsh weather and UV radiation.

KEE-Stone FB 60 fleece-backed thermoplastic membrane stands up against harsh weather and UV radiation.

Garland has released the KEE-Stone FB 60 fleece-backed thermoplastic membrane which exceeds standard weathering tests and stands up against harsh weather and UV radiation. In accelerated weathering tests, KEE-Stone showed no signs of cracking or cratering even at 100 times magnification, which is 10 times more than the ASTM D 6745 standard requires. KEE-Stone’s compound, formulated using DuPont Elvaloy HP Ketone Ethylene Ester (KEE), provides resistance to UV degradation and heat resistance while retaining low-temperature flexibility, which translates into a lasting roof.

KEE enhances the performance of the PVC by permanently locking in its flexibility, eliminating plasticizer migration and allowing the membrane to remain tough and flexible throughout the entire lifecycle of the roof. Garland’s KEE-Stone membranes contain the KEE formulation throughout the entire sheet, further increasing its level of performance. The membrane is also reinforced with a polymer-coated scrim. The design of the scrim allows the KEE compound above and below the scrim to fuse together, imparting puncture, tear and tensile strength to the membrane.

Garland’s two-ply, hybrid KEE-Stone system will provide the protection of a traditional modified bitumen roof system with the appearance of a single-ply system.

Jandrex LLC has released its Mini Breach X, which temporarily seals roof membrane punctures, rips and tears, and other breaches found during inspections, maintenance work and new roof installs. The product also flags these breaches for easy discovery by post-inspection repair workers. The typical “flagging” technique is to place a circle around each breach with a pen or permanent marker, and, in some cases, plot each breach on a roof-plan or drawing. This practice is time-consuming and sometimes difficult for repair workers to find. In addition, it could be weeks before a post-inspection repair worker appears onsite to fix breaches. The Mini Breach X was designed to solve these flaws by sealing and flagging a breach with one system.

Duro-Last Achieves Gold Certification for All Membrane Product Lines

Duro-Last has achieved gold certification for all membrane product lines under the NSF American National Standard for Sustainable Roofing Membranes – NSF/ANSI 347. Certified by UL, this standard represents that Duro-Last manufactures a product that is third-party verified as sustainable, durable and high performing. The certification applies to Duro-Tuff, Duro-Fleece and Duro-Last EV membranes, in addition to Duro-Last membrane, which was certified in 2015.

With the certification of these four product lines, Duro-Last has the most roofing membrane product lines certified in the industry—furthering the company’s commitment to sustainability and transparency.

“Duro-Last believes in the importance of sustainability,” says Jason Tunney, Duro-Last’s executive vice president and general counsel. “These third-party certifications confirm what we already know about our products.”

Duro-Last has worked with UL for many years on product testing, including the UL 790 Spread of Flame Test, UL 1256 Direct to Deck (insulation) and the UL 2218 Hail Impact Test. As the sustainability business division of UL, a premier global independent safety science company that has championed progress for 120 years, UL Environment works to advance global sustainability, environmental health, and safety by supporting the growth and development of environmentally preferable products, services, and organizations.

NSF/ANSI 347 was developed by the NSF National Center for Sustainability Standards (NCSS) through a consensus-based public process with a multi-stakeholder group of participants and, according to their website, is based on life-cycle assessment principles. NSF/ANSI 347 employs an easy-to-use point system to evaluate roofing membrane products against established prerequisite requirements, performance criteria and quantifiable metrics in five key areas:

  • Product design
  • Product manufacturing
  • Membrane durability
  • Corporate governance
  • Innovation

Obtaining this certification will help Duro-Last’s membranes meet the market demand for products that comply with green building standards and codes like the Green Building Initiative’s Green Globes and the International Green Construction Code (IgCC). Product specifiers and purchasers are under pressure to find products that meet their sustainability criteria, and having the NSF/ANSI 347 certification can give them the peace of mind of specifying a third-party verified product.

Duro-Last has also published environmental product declarations (EPDs) for Duro-Tuff, Duro-Fleece and Duro-Last EV membranes. This is in addition to the previously published EPD for Duro-Last membrane—the first product-specific PVC EPD in the North American roofing industry.

Certified by NSF International, the Duro-Last EPD reports environmental impact data, which assists building contractors, architects and designers in making more informed purchasing decisions. EPDs are increasingly used across many industries to enable product manufacturers to bring transparent environmental data to customers.

“Duro-Last is proud to publish product-specific EPDs for PVC roofing,” Tunney says. “We have always known that the Duro-Last Roofing System is a durable, flexible, serviceable and recyclable product, and now these EPDs can give building owners and specifiers peace of mind.”

ARMA Selects Top Installations in North America

The Washington, D.C.-based Asphalt Roofing Manufacturers Association selected the winners of its Quality Asphalt Roofing Case Study (QARC) Awards, an annual program that recognizes exceptional roofing projects in the U.S. and Canada.

The Gold Award honored John Foster, a general contractor in Esparto, Calif., for his company’s installation on a star-shaped home. The homeowners required a roofing system with a style that wouldn’t get lost in the bold architecture. PABCO Roofing Products Premier Advantage Granite shingles provided the necessary aesthetic to complement the home while protecting it from the windy, damp coastal environment to which it is subjected.

The Silver Award was given to Advanced Roofing Inc., Fort Lauderdale, Fla., which was called upon to install a new low-slope asphalt roofing system on two buildings at the PGA National Resort and Spa in Palm Beach Gardens, Fla. The contractor chose a SOPREMA three-ply SBS-modified bitumen roofing system with a base sheet and cap sheet that delivered a pristine appearance while protecting the roof from harsh weather and heavy foot traffic.

Precision Roofing, Hialeah, Fla., received the Bronze Award for the roof it installed on Northeast Regional Library, Aventura, Fla. A GAF hybrid built-up/SBS-modified bitumen roofing system using three plies of GAFGLAS Ply 4 Ply Sheet and a Ruberoid EnergyCap 30 Granule FR membrane was chosen because the contracting company knew the system would meet the project’s durability requirements and budget restrictions.

“Each of the submissions we received this year illustrated the beauty and curb appeal that asphalt roofing can provide,” says Reed Hitchcock, ARMA’s executive vice president. “These winning projects were singled out for successfully using the unique qualities of their roofing materials to deliver superior protection for a building, whether from salty storms, high winds, or other wear and tear.”

Asphalt and Polyurethane Create Durable Membrane

The Garland Co. Inc.’s OptiMax polyurethane-modified asphalt-based roof membrane is developed with a process that combines asphalt with polyurethane to create a durable and long-lasting modified membrane.

The Garland Co. Inc.’s OptiMax polyurethane-modified asphalt-based roof membrane is developed with a process that combines asphalt with polyurethane to create a durable and long-lasting modified membrane. OptiMax becomes increasingly resilient as it ages because, with time, polyurethane molecules are chemically linked with one another. The process was first used in Europe in the paving industry.

When traditional SBS-modified membranes age, the oils within the membrane heat up and “cook out”, causing cracking and eventually leaking. OptiMax utilizes an “active modification” process, which involves chemically reacting the polyurethane modifier to specific molecules within the asphalt. This modification provides enhanced long-term performance characteristics and weatherability.

Its performance is further improved by the fact that minerals are more strongly attracted to the polyurethane in the OptiMax membrane. The result is improved adhesion thus providing UV protection, preventing the likelihood of cracking and leaking issues common in traditional membranes. During advanced surface testing, OptiMax had fewer cracks when compared to traditional asphalt-modified membranes and retained its tensile strength in the face of damaging UV radiation.

“OptiMax has the ability to literally change the face of the roofing industry. This new technology will revolutionize the market and redefine expectations of building owners in terms of performance and protection. OptiMax has been engineered to outperform other commercial roofing products in the industry,” explains Melissa Rus, Garland’s director of research and development.

This toughness combats the negative effects of natural expansion and contraction caused by heating, cooling, light and moisture. In addition, the brilliant white CoolStar surface is factory applied for hassle-free, one-step installation, which helps reduce labor costs.

Creating Visual Impact with Copper and Silver Roofing Membranes

Whether you’re re-roofing a historic building that needs to maintain its aesthetics or you’re working on a new roof construction that has to make a statement, there are many instances in which a building owner would want his or her roof to generate a specific architectural appeal. The most difficult part of this is balancing durability and beauty with cost. Roof systems today have evolved to solve this conundrum. Now, copper and silver synthetic PVC membranes are being used to achieve the desired appearance of a metal standing-seam roof at a fraction of the cost without sacrificing performance.

Alternatives to Metal Roof Systems

Michigan State University replaced the existing slate roof system with SOPREMA SENTINEL Copper Art to provide the desired appearance and required long-term performance.

Copper and silver synthetic membranes are great cost-effective alternatives to metal roofs. As flexible synthetic systems, these roof membranes are economical and easy to install by conforming to complex geometries.

Certain synthetic PVC roof membranes on the market today are offered in a variety of colors, some of which can mimic the look of metal roofing. While these roof membranes offer the proven long-term performance of flexible polyvinyl chloride (PVC), they provide the metal appearance via the addition of pigments that can chalk or fade as the pigmented membrane ages, therefore losing the desired aesthetic feature.

Conversely, SOPREMA SENTINEL Copper and Silver Art PVC membranes incorporate copper or aluminum metallic powder into the PVC formulation, producing an enhanced metallic look. Unlike pigmented membranes, SENTINEL Copper Art provides the same weathering capabilities as traditional standing seam copper—the SENTINEL Copper Art will patina as a traditional copper roof would. Silver Art is unique because the color will not fade due to the addition of metallic powder, and its surface layer is factory embedded with an acrylic shield treatment to resist dirt pickup and chalking. Copper Art and Silver Art membranes provide the long-lasting aesthetic appearance and waterproofing abilities of a metal roof.

Applications for Copper and Silver Membranes

Copper and silver roof membranes are often used on buildings where aesthetics are important. Historic buildings, churches, schools, government buildings and army bases are a few examples of where this type of roof membrane has been installed. These buildings may require a particular appearance or designers may simply wish to update the appearance or provide some panache. Mansards or other areas of visible existing light-gauge metal roof systems may be present on these buildings and flexible copper and silver roof membranes may be used as an alternative aesthetic solution.

SENTINEL Silver Art met Glenside Public Library’s leak-free and architectural needs, plus the roofing contractor liked that the SENTINEL membrane was easy to install and looked great upon completion.

SENTINEL Silver Art met Glenside Public Library’s leak-free and architectural needs, plus the roofing contractor liked that the SENTINEL membrane was easy to install and looked great upon completion.

For example, since 2007, the slate roof of the Snyder-Phillips residence hall at Michigan State University had been leaking. The university needed to replace the existing slate roofing system with a new system that would meet the aesthetic requirements of the historic building. SOPREMA SENTINEL Copper Art was installed as a cap sheet to provide the desired appearance and the required long-term performance.

In addition, the Glenside Public Library had an existing standing-seam roof that was tied-in to a low-slope ethylene propylene diene monomer (EPDM) roof. The tie-in between the two materials was problematic and continuously leaked. The library wanted to preserve the standing-seam appearance, but the noise created by wind and rain on the metal roof was a concern.

SOPREMA SENTINEL Silver Art was selected because it could provide the desired look while eliminating the tie-in issues between the steep- and low-slope roofing materials. SENTINEL Silver Art met the library’s leak-free and architectural needs, plus the roofing contractor liked that the SENTINEL membrane was easy to install and looked great upon completion. In addition to its aesthetic appeal, SENTINEL Silver Art also offered the benefit of significant noise reduction when compared to the former metal roof system.

Roofing Technology Advancements

As roofing technology advances, the options for creating a desired aesthetic have evolved. SENTINEL PVC Copper and Silver Art are high-performance roof membranes that provide the appearance of metal with the flexible, long-term performance of PVC, without the weight, expense or complexity of a traditional metal roof.
