Page 30 of 59 September 2015 • 29 A patented composite insulated concrete wall panel system produced at 23 licensed U.S. and Canadian plants has obtained a two- hour fire resistance rating according to ASTM E119 – 11A, Standard Test Methods for Fire Tests of Building Construction and Materials. Under University of Miami Structures and Materials Laboratory staff, staff of Medley, Fla.-based Fenestration Testing Laborato- ry Inc. subjected 10-ft.-square THiN-Wall specimens, with 3-in. concrete layers sand- wiching 4-in. of XPS insulation, to sustained flexural. During the fire exposure, no visual changes to the specimens were observed. The THiN-Wall system uses the non-con- ductive, glass fiber reinforced NU-Tie to pro- duce an extremely strong and energy efficient insulated concrete wall panel. Additional information on the E119 – 11A test result or THiN-Wall licensing can be obtained from Composite Insulated Concrete Systems' Doug Gremel, 800/869-0359; BRIEFS MANUFACTURERES THiN-Wall attains two-hour fire rating WORLD'S FIRST BATTERY-OPERATED REBAR TYING TOOL In 1993, MAX developed the world's first battery-operated rebar tying tool for the Japanese market.
