2. SCOPE

The purpose of this test was to verify performance characteristics of the U.S.Aluminum Series 4500 CW 2-piece vertical with strap when tested in accordancewith AAMA 501-94, Methodsof Tests for Exterior Walls.

3. SUMMARY

The U.S Aluminum Series 4500 CW with 2-piece vertical with strap was tested inaccordance of AAMA 501-94 and passed the short form requirements noted inlaboratorytest specificationssectionfor:

. Air Infiltration @ 6.24 PSF, (.30 kPa) with an air infiltrationrate of <0.01Cfm/Ft2«0.18m3/hr/m2).

. Uniform Load Deflection @ 75.0 PSF (3.59 kpa) with a positive deflectionof .365" (9.27 mm) and a negative deflection of .475" (12.07 mm) with anallowable of .548" (13.92 mm).

. Proof Uniform Load Structural @ 113 PSF (5.41 kPa) positive/negativewith no glass breakageand 0.031" (.77mm) permanent deformation.
