Podcast episode 44 features Johns Manville's Technical Sales duo, Rick Gustin and Rob Hughes. Rick and Rob discuss their wind convergence presentation at IIBEC's International Convention and Trade Show in Phoenix.
For more than 160 years, people have been at the core of everything Johns Manville does. Recently that commitment took center stage in Georgia, where JM joined forces with the National Roofing Contractors Association to help foster the talents and passions of the next generation of skilled workers.
JM and NRCA teamed up at SkillsUSA's National Leadership & Skills Conference. Held annually in June in Atlanta, NLSC is a week-long celebration of the skilled trades and the accomplishments of career-ready leaders from across the United States, according to SkillsUSA.
The event each year draws more than 16,000 attendees, including students, instructors, industry partners and government officials. The highlight of the gathering is the NLSC, featuring more than 6,000 state champions competing for national gold, silver and bronze medals in 115 competitions.
Limited roof access didn't stand in the way of finding an affordable reroof for The Lighthouse of Houston, a nonprofit that has been serving those with limited vision for more than 80 years. Key to that was a long-standing relationship with Peak Roofing Inc., which worked with the nonprofit to create a cost-effective, 20-year roofing solution that did not alter the aesthetics of the building or disrupt the good work being done inside.
Also key was JM innovation — specifically its new ENRGY 3® HD cover board, which provides greater R value than a gypsum cover board but is lighter, and easier to manage and maneuver in tight spaces.
In addition to ENRGY 3® HD, the recover roof assembly includes 60 mil JM PVC SD Plus membrane.
JM team members got hands-on last month to help girls build construction skills and help the industry build a pipeline of future professionals at Let's Build Construction Camp for Girls Phoenix.
The camp — June 10-14 at Carpenters Local Union 1912 in Phoenix, Arizona — was founded to “ignite the spark within girls to explore the built environment through architecture, engineering, construction and building materials manufacturing-related careers." Started in 2016 by Kirsten Fallon, Jon Lattin, and Janet Grazul, Let's Build “takes a proactive approach to addressing workforce shortages and increasing women participation in the AECM industry by introducing young girls to the opportunities available to them."
A team charged with tackling a reroofing project at the Port of San Diego recently proved worth its salt, even as it dealt with the challenges posed by salt air and high-end cargo.
Chambers, Inc., dba Roof Construction, won the job to reroof National City Maritime Terminal Warehouse 24-B using a Johns Manville TPO system as the basis for design. And JM stepped in to help Sillman Architecture design a system that would meet the job's performance requirements, which included being able to withstand the high-moisture saltwater environment.
Other challenges included being careful not to let any debris fall onto the property, which is the site of a constantly rotating inventory of high-end vehicles.
The Contemporary Art Museum in St. Louisturned to a team of experts who designed and installed a reroofing project that delivered artful results on a tight timetable.
Known locally as CAM St. Louis, the museum is part of the city's popular Grand Center Arts District. Its 500,000 annual visitors are just shy of double the city's year-round population. Exhibits rotate annually from an off-site collection of more than 36,000 objects and display around 2,700 pieces. In 2021, the roof protecting these precious objects started to fail.
The design and implementation for reroofing the two-story, 16,135-square-foot museum posed challenges, including retaining aesthetic features while improving detailing, the addition of permanent rooftop safety equipment, and performing all work within a scheduled two-month shutdown of the museum.
Thanks to our distribution partners, the versatility and reliability of JM's Mod Bit roofing systems took center stage this month in Florida. Teaming with SPEC Building Materials and Beacon Building Products, JM hosted a Modified Bitumen Roofing Day 2024 in both Orlando and Medley.The two one-day events featured technical savvy mixed with food and a dash of fun. Attendees learned application techniques from JM technical experts for a variety of Mod Bit roofing system components including APPEX®, DynaGrip®, DynaWeld® and PermaFlash®.They watched and participated in live demos, dined on local food truck fare, networked with their industry peers and vied for a chance to win raffles for Patriot Coolers.
