"We realized that using a FleeceBACK membrane and low-rise insulating foam adhesive would be a perfect fit for this project," the roofing supervisor said about his decision to use Carlisle's 100-mil FleeceBACK EPDM membrane with FAST Adhesive.
| (Carlisle, Pa.) - In the heart of the Midwest along the Mississippi River, is a community rich in history. Burlington, Iowa, established in the mid 19th century, was erected by a large number of talented European immigrant carpenters and craftsmen who were part of the settlement. In the heart of Burlington is Autumn Heights, an eight-story housing complex where senior tenants can enjoy a birds-eye view of the daily activities of their quaint historic community. Unfortunately, these activities typically include winds that roll off the merciless river at speeds of more than 30 miles per hour.
"After years of combating windy conditions, the roof atop Autumn Heights began to fail," said Marshal Walz, director of the Low Rent Housing Agency of Burlington, Iowa. "We had to 'sandbag' the original surface to keep it from completely delaminating and knew that we must replace it before the high winds created a bigger problem."
Frank Millard & Company, Inc., located in Burlington, bid out the original specifications. The plans called for placing OSB board on top of the existing 10,000 square foot roof. The board would be mechanically fastened to the concrete deck.
The lengthy and labor-intensive project concerned Mr. Walz. "With a concrete and steel structure, we were worried about noise levels disturbing, and potentially upsetting, our tenants," he said.
Frank Millard & Company's roofing supervisor, Gary Newberry, met with Carlisle's Rob Mulaney to discuss alternative methods of installation. Based in nearby Des Moines, IA, Mulaney, Technical Sales Representative, recommended applying 100-mil FleeceBACK® EPDM membrane directly to the existing substrate.
"We realized that using a FleeceBACK membrane and low-rise insulating foam adhesive would be a perfect fit for this project," Newberry said about his decision to use Carlisle's 100-mil FleeceBACK EPDM membrane with FAST™ Adhesive.

"We had to 'sandbag' the original surface and immediately began to plan to replace it before the high winds created a bigger problem," Marshall Walz, director of the Low Income Housing Agency of Burlington, said.
| The FleeceBACK system offered several advantages for the Autumn Heights project. Not only is the system adhered using FAST Adhesive which reduces application noise, it has achieved a FM 1-945 uplift rating from Factory Mutual (FM). Industrial and commercial companies around the world rely on products and services that are FM Approved and specification tested. The FM Approved mark, which is backed by scientific research and testing, tells customers that products conform to the highest standards.
The FM rating system is based on a wind uplift test that applies an increased amount of pressure to the underside of the roofing system to determine the degree of pressure the material can withstand. The rating of FM 1-945 equates to the resistance to 990 pounds of uplift pressure per square foot. A high FM rated roofing system that can resist heavy winds is essential for areas of the country where Mother Nature produces structurally damaging winds. The roofing system that received an FM 1-945 wind uplift rating was the FleeceBACK system applied over a structural concrete deck similar to the Autumn Heights scenario. The membrane was also attached with the insulating FAST Adhesive that creates a tenacious long-term bond.
To provide added assurance that the FleeceBACK system would withstand the test of time, Carlisle representatives conducted test cuts to make sure the project would be acceptable for warranty. After the test results were in, Frank Millard & Company recommended Carlisle's FleeceBACK membrane to the architect.
"We received excellent technical support from Carlisle. Rob Mulaney helped us throughout the process, including changing specifications and presenting and demonstrating the advantages to the housing agency," Newberry said. "The agency knew that this was going to be our first FleeceBACK membrane installation, but Carlisle assured them that they would have technical support assisting every step of the way."
Frank Millard & Company started the project by removing the existing membrane. By cutting the membrane into squares, the workers were able to peel it back, leaving little remnants on the substrate. After removing the existing membrane, the reroofing team applied the FAST Adhesive using a spray rig. The FleeceBACK membrane was adhered directly to the existing insulation.
Despite high winds, which averaged 25-30 miles per hour throughout the installation process, Frank Millard & Company completed the project in 5 days. According to roofing supervisor, Gary Newberry, by using the FleeceBACK membrane, they were able to drastically cut down on noise and labor, which benefited both Autumn Heights and the roofer.
"By using Carlisle's FleeceBACK EPDM with FAST Adhesive roofing system, we were able to provide Autumn Heights with a quick, easy and quality reroofing solution," Newberry explained. "We set up a crane on site to take our materials to the roof and spent a couple hours setting up. Other than that, we hardly made a sound."

| Frank Millard & Company was very pleased with the support received during their first FleeceBACK membrane installation. "Throughout the entire process, Carlisle really guided us and brought the whole project together," Newberry said. "It was like having an audio/visual instruction manual with us on the job site."
After the project, Frank Millard & Company purchased a spray rig for future installations. "We were impressed by the success and ease of the installation and decided to utilize Carlisle's FleeceBACK membrane and FAST Adhesive on other projects," Newberry added.
Mr. Walz couldn't be happier. "The work has been a complete success. The key was the time savings and noise reduction they achieved," he said. Walz is also confident that with a FM 1-945 rating backed with a Carlisle systems warranty, sandbags will only be needed in Burlington to keep the mighty Mississippi from invading the historic riverfront town during rainy months.
