Arkema Coating Resins, a business unit of Arkema, has added to its line of waterborne binders for use in formulating roof coatings. The new product is ENCOR Flex 192, a modified acrylic latex binder designed for coatings used in the restoration of low-slope, commercial thermoplastic polyolefin (TPO) roofing membranes. Properly formulated, ENCOR Flex 192 offers outstanding dirt pickup resistance and adhesion to TPO, and can eliminate the need for a solvent primer to help lower roof maintenance and restoration costs.

The AC Cool Roof Binder systems are based on Kynar Aquatec PVDF binders, developed by Arkema’s fluoropolymer group, and ENCOR Flex polymers from Arkema Coating Resins.

Currently three systems are available, allowing greater formulation flexibility across different applications:

  • AC III Binder System – This system uses a Kynar Aquatec FMA-12 PVDF based topcoat and ENCOR Flex 187 all acrylic or ENCOR Flex 192 modified acrylic basecoat to provide the highest possible level of performance and durability. It is designed primarily for the most demanding cool roof coating applications.
  • AC II Binder System – Utilizing a proprietary ENCOR Flex 187 all acrylic polymer or ENCOR Flex 192 modified acrylic latex, this base and topcoat system delivers excellent performance and meets ASTM D-6083, “Standard Specification for Liquid Applied Acrylic Coating Used in Roofing.”
  • AC I Binder System – This ENCOR Flex 3186 styrene acrylic system provides a good mix of performance and value for less demanding applications.

Roof Report

DPR Construction is a national technical builder specializing in highly complex and sustainable projects. In less than 10 months, the design-build team researched, designed, permit-ted, and built a highly efficient and modern workplace with numerous innovative sustainability features.

In addition to natural daylighting, the office features an 87-foot zinc-clad solar chimney, which releases hot air from the building while drawing cooler air in; shower towers that act as evaporative coolers to regulate building temperatures; 87 operable windows designed to open and close automatically (based on indoor/outdoor temperatures); and two “vampire” shut-off switches to keep electrical devices (radios, cell-phone chargers, microwaves) from using plug energy when no one is in the office.

Access to the building was limited during construction. Spray foam roofing, which took about seven days to complete, had to be done in small quadrants because of the tight schedule as work was progressing in the other sections. The roofing workers were challenged by the barrel-shaped roof, which created footing difficulties, and the many penetrations that had to be flashed, including all PV support legs, Solatubes, skylights and HVAC penetrations. Work was completed in the middle of winter, so additional protections and efficiencies were required.

The circa-1972 building has been officially certified as a Net-Zero Energy Building by the Seattle-based International Living Future Institute through its Living Building Challenge program. It also has received LEED-NC Platinum certification from the U.S. Green Building Council, Washington, D.C.

GAF has made a significant investment in upgrading the building, using its own energy-efficient TPO roofing for the roof. The refurbished building brings the company’s departments and functions together under one roof to foster even greater collaboration and teamwork while improving the company’s overall operating efficiency. The current location in Wayne has 11 buildings spread over a sprawling 99-acre campus. The new location is a single, 330,000-square-foot state-of-the-art facility that will house all of the company’s operations on three floors. “We’re all looking forward to the many advantages that our new facility will provide,” says Tafaro. “We’re a very customer-focused company, and the new facility will only enhance our ability to create value for our customers.” The architecture, layout and furniture for the new building were selected to facilitate effective communication, quick decision-making and improved efficiencies.

Over the past few years, GAF has invested $350 million in capital improvements, including several new manufacturing plants for its commercial roofing products.

U-Anchor Solar Attachment System Withstands Hurricane

The U-Anchor 2000 has withstood another blast of hurricane force winds. The 800 kW Trina solar power generation system was secured to a Carlisle TPO roof membrane in a hybrid system, consisting of U-Anchor 2000 attachments and ballast solar racking on top of the Westin Dawn Beach Resort & Spa in St. Maarten. The system provides solar electric power to 317 guestrooms, restaurants, restrooms, laundry facilities and the spa.

The hurricane slammed into St. Maarten on Oct. 13 with no damage to the rooftop attachments and only minor debris-blown damage to the solar panels. Surrounding homes and boats were destroyed and the community’s water and power utilities reported outages. The solar electric power at the resort remained uninterrupted.

Hurricane Gonzalo was the second time the U-Anchor’s held a rooftop solar project securely in place while hurricane force winds blasted a rooftop solar project. U-Anchors shield a project on a large factory roof in Yonkers, New York, from 90 mph wind gusts during Superstorm Sandy in October 2012. Anchor Products completed the project in partnership with Sollega, Inc., which provided the ballasted racking portion of the hybrid system.

Anchor Products, LLC is the manufacturer of the U-Anchor 2000 patented rooftop solar attachment products for the attachment of solar equipment and accessories to ridged and flexible film roof membranes. When properly installed, the U-Anchor can withstand approximately 1,000 lbs of ultimate load force in tension, and approximately 2,000 lbs of ultimate load force in shear.

U-Anchor 200 can be used on ballasted or non-penetrating designs. U-Anchors maintain the roofing manufacturer’s warranty and can be quickly installed at a rate of 12 per man hour. U-Anchor 2000 and all of Anchor Products rooftop attachments come with an industry standard material warranty.

The U-Anchor line of products can also attach mechanical equipment, electrical conduit, plumbing pipes, HVAC ducting, satellite dishes, windscreens, lightning protection and antennas, among many others.

TPO Has Begun Shipping from GAF’s New Cedar City, Utah, Plant

GAF has started shipments from its new thermoplastic polyolefin (TPO) and polyisocyanurate (ISO) plant in Cedar City, Utah. Construction of the state-of-the-art site was announced in spring of 2013; it houses GAF’s third TPO and third ISO production lines (and it’s the company’s second combined TPO/ISO facility). TPO began shipping from Cedar City on Aug. 1 and ISO products are expected to begin shipping in early 2015.

The 541,000-square-foot plant produces the full line of GAF TPO products, including EverGuard TPO and EverGuard Extreme TPO, and it will manufacture both ISO roof insulation and residential sheathing. In addition, the plant will include a new training center for CARE (the Center for the Advancement of Roofing Excellence), to support the continued and growing demand for their training classes.

“Our venture in Cedar City is an example of GAF’s continued strategic investment in the commercial roofing industry,” stated Gerry Messina, GAF’s executive director of commercial marketing. “The facility will give us the ability to better service our customers throughout the country.”

An American-owned company with American-made products, GAF is proud to create additional jobs in the U.S. There are currently 40 employees at the plant, with an additional 10-15 expected. The company also produces TPO at its Mount Vernon, Ind., and Gainesville, Texas, facilities.

Corrugated Metal Applied in Unusual Ways Brings a 1918 Building into the 21st Century, and a TPO Roof Protects Its Icon Status

Dorchester is Boston’s largest neighborhood and one of its most diverse. In July 2013, the Four Corners commuter rail station opened in the Mount Bowdoin section of the neighborhood, setting in motion plans to bring more transit-oriented buildings to Dorchester. Among the first projects to meet this goal is the AB&W Building, a mixed-use facility located about one block from the Four Corners station.

Originally built in 1918 as a car dealership that sold Model T’s, the AB&W Building has become a neighborhood icon.

Originally built in 1918 as a car dealership that sold Model T’s, the building has become a neighborhood icon. Therefore, even though the goal was to create an active center that connected tenants and others with the new commuter station, Project Architect P. Nicholas Elton, AIA, a partner in Elton + Hampton Architects, Roxbury, Mass., still desired to connect the new development to its surroundings as much as possible. “The intention was to create a development that was a little denser than the rest of the neighborhood but still respected and tried to be a little like the neighborhood,” he says.

To achieve this, the decision was made to maintain the front façade of the original building and integrate it with all new construction. Elton used specific building materials to pay homage to the surrounding area. For example, a yellowish brick on the front of the new second and third stories of the AB&W Building mimics the brick used on the 1930s-era building across the street. The addition of fiber-cement and corrugated-metal siding breaks up the enlarged AB&W Building’s scale so it better fits in its location.

Elton, who is a fan of corrugated metal, decided also to have some fun with the material, flexing it in unusual ways for overhangs above windows and doors. “When you start using materials that you are using on the walls on the roof, then you get to play a little game,” he says. “The material will come down a wall and wrap into the roof; there are a lot of materials you can’t do that with but you can when you use corrugated.”

It took a team of three metal fabricators from Lancaster Enterprises Inc., a family roofing business in Dedham, Mass., to carefully curve and flex the corrugated metal to meet Elton’s specifications. Meanwhile eight to 10 of the metal fabricators’ colleagues were installing a watertight TPO membrane on the AB&W Building’s six newly constructed roofs.

The 32,096-square-foot AB&W Building features 24 affordable-housing units, primarily rentals with a few coop ownership opportunities, and 3,300 square feet of ground-floor retail space.

OLD BECOMES NEW

Elton + Hampton Architects concentrates its work on what the firm’s partners—Elton and Bruce M. Hampton, AIA—refer to as socially relevant projects. The firm almost exclusively works with non-profit organizations on affordable housing and housing for special populations, as well as community-resource buildings.

The 32,096-square-foot AB&W Building features 24 affordable-housing units, primarily rentals with a few coop ownership opportunities, and 3,300 square feet of ground-floor retail space. One retail space is an art gallery and there currently are conversations to merge the other two retail locations for a restaurant specializing in Caribbean cuisine.
