May 19, 2017 – CAC-RCI Conducts 2017 Spring Meeting

The Chicago Area Chapter of RCI, Inc. (CAC-RCI) conducted its annual spring program on May 19, 2017, at the Village Links of Glen Ellyn in Glen Ellyn, IL, with 42 members, guests, speakers, and tabletop exhibitors attending. The tabletop exhibitors included Carlisle Syntec Systems, OMG Roofing Products, Hunter Panels, FiberTite, and Tecta America.

The meeting began with networking and tabletop exhibitor visits followed by lunch, and then the presentations were given. The speakers for the program were Grant Stahl with Hunter Panels, presenting “Continuous Insulation: Energy Efficiency and Performance Comparison,” and Timothy Harris with the Federal Aviation Administration, discussing “How to Fly Your Drone for Business Safely and Legally.”

Grant Stahl of Hunter Panels talks
about continuous insulation.

Grant Stahl’s presentation focused primarily on exterior wall insulation including the various types, properties, and ratings. He talked about polyisocyanurate, SPF, EPS, XPS, mineral wool, and fiberglass batts. He compared the global warming potentials of the various types, taking into account acidification, ozone depletion, and eutrophication. He explained construction difficulties and best materials and methods. He examined air flow and moisture flow through the various materials and computer modeling results. He presented the “ideal wall” with all insulation on the exterior side of the air barrier, and he also discussed the various types of insulation facers including glass fiber, paper, and foil, concluding that permeable glass fiber facer is best for exterior walls.

Tim Harris of the FAA discussed the safe
operation of unmanned aircraft.

 

 

Unmanned Aircraft Specialist Timothy Harris, of the FAA, began his presentation discussing U.S. airspace rules for unmanned aircraft (UA). He discussed the difference between recreational and commercial use of small UAs. He stated that under 14 CFR (Part 107) for commercial use, an operator needs a remote pilot certificate, must be 16 years of age or older, and must pass a TSA vetting process. In addition, to properly operate the UA it must travel under 100 mph, must not be operating over people unless they are part of the operation, and must yield to manned aircraft. Further, for legal operation of the UA, the operator must maintain line of sight, must be 400 feet or less above ground level unless within 400 feet of the structure, must be operating a UA weighing less than 55 pounds, and must operate the UA during daylight hours. He indicated that information is available at FAA.gov/uas/. New unmanned aircraft systems (UAS) facility maps are available for use in obtaining airspace authorizations and waivers of the listed height restrictions, and the maps allow expediting of the petitions. He stated that there are UAS security-sensitive restrictions that protect military facilities, nuclear plants, and other critical facilities. He concluded by recommending that all unsafe UA activities should be reported to the FAA.
