Market St„ Suite B <br /> York, PA 17403 <br /> 18 April 2007 <br /> Rich Gibson <br /> Gorell Windows & Doors, .LLC <br /> 1380 Wayne Avenue <br /> Indiana, PA 15701 <br /> RE: Florida Evaluation Report, Mullion #981 15 <br /> Dear Mr. Gibson; <br /> The following Gorell Windows & Doors, LLCC product, Huricane Mullion #98115, has <br /> been tested and analyzed in accordance with the 2006 Supplement to the 2004 Florida <br /> Building Code, Section 1714.5.5 Mullions Occurring Between .Individual Window and <br /> Glass Door Assemblies. The testing was done at Architectural Testing. Inc., and the <br /> results are in their report 65355.01- 109 -44. Structural testing in accordance with AAMA <br /> 450 -06 was done on a 3 wide. mulled PVC picture window Series 5301 assembly with <br /> overall dimensions of 13' 0" wide by 6' 0" high and each window being 4' 4" wide by 6' <br /> 0" high. The mullion is a composite steel and plywood, attached to the PVC frames. <br /> From the test results. I have calculated the moment of inertia of the mullion and <br /> determined that deflections are critical for design wind pressures of +/ -50.0 psf. Then. <br /> using rational analyses. I have calculated the maximum mullion lengths for various <br /> window widths, the results of which are in the following table. <br /> DESIGN WIND PRESSURE +1- 50.0 PSF <br /> WINDOW WIDTH 1' 6 " 2' 4" 3' 0" 4' 4" 5` 1" 6 ' 0 ,. 7' 0" 8' 0" 9 ' 0„ 10' f)• <br /> MULLION LENGTH 6' 8" 5'10 5' S" 5' 2 " 5' 1" 5' 1" 5' 1" 5' 1" 5' 1" 5` 1" <br /> The above loads are allowable design wind pressures and are in conformance with the <br /> 2006 Supplement to the 2004 Florida Building Code. Tables 1609.6.2.1(2) and <br /> 1609.6.2.1(4). A limiting factor for this mullion is that it does not qualify for the High - <br /> Velocity Hurricane Zones. Installation drawing by Gorell is attached to test report. If <br /> there are any questions about this evaluation report, or if anything additional is required. <br /> please contact me. <br /> Sincerely yours: <br /> Allen N. Reeves.
