No water infiltration shall occur in any system under a differential static pressure of 6.24 lbf/sq. ft. (300 Pa) after 15 minutes of exposure in accordance with ASTM E 331.
4.
Pressure Equalized Rain Screen Systems shall comply with AAMA 508 Voluntary Test Method and Specification for Pressure Equalized Rain Screen Wall Cladding Systems.
2.5
ACCESSORlES
A.
Extrusions, formed members, sheet, and plate shall conform to ASTM B 209 and the recommendations of the manufacturer.
B.
Panel stiffeners, if required, shall be structurally fastened or restrained at the ends and shall be secured to the rear face of the composite panel with silicone of sufficient size and strength to maintain panel flatness. Stiffener material and/or finish shall be compatible with the silicone.
C.
Sealants and gaskets within the panel system shall be as per manufacturer's standards to meet performance requirements.
D.
Fabricate flashing materials from 0.030 inch (0.76 mm) minimum thickness aluminum sheet painted to match the adjacent curtain wall / panel system where exposed. Provide a lap strap under the flashing at abutted conditions and seal lapped surfaces with a full bed of non-hardening sealant.
E.
Fasteners (concealed, exposed and non-corrosive): Fasteners as recommended by panel manufacturer. Do not expose fasteners except where unavoidable and indicated on the approved shop drawings. Match finish of adjoining metal.
PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Surfaces to receive panels shall be even, smooth, sound, clean, dry and free from defects detrimental to work.
B.
Do not begin installation until substrates have been properly prepared. If substrate preparation is the responsibility of another installer, notify Contractor and Architect of unsatisfactory preparation before proceeding.
3.2
INSTALLATION
A.
Erect panels in accordance with manufacturer's requirements and approved shop drawings, plumb, level, and true.
B.
Attachment system shall allow for the free and noiseless vertical and horizontal thermal movement due to expansion and contraction for a material temperature range of -20 degree F to +180 degree F (-29 degree C to 82 degrees C). Buckling of panels, opening of joints, undue stress on fasteners, failure of sealants or any other detrimental effects due to thermal movement will not be permitted. Fabrication, assembly, and erection procedure shall account for the ambient temperature at the time of the respective operation.
C.
Panels shall be erected in accordance with an approved set of shop drawings.
D.
Anchor panels securely per engineering recommendations and in accordance with approved shop drawings to allow for necessary thermal movement and structural support.
E.
Conform to panel fabricator's instructions for installation of concealed fasteners.
F.
Do not install component parts that are observed to be defective, including warped, bowed, dented, abraded, and broken members.
G.
Do not cut, trim, weld, or braze component parts during erection in a manner which would damage the finish, decrease strength, or result in visual imperfection or a failure in performance. Return component parts which require alteration to shop for rework, if possible, or for replacement with new parts.
 
** NOTE TO SPECIFIER ** Delete if exposed fasteners are used.
 
H.
Separate dissimilar metals and use gasket fasteners where needed to eliminate the possibility of corrosive or electrolytic action between metals.
3.3
ADJUSTING AND CLEANING
A.
Remove and replace panels damaged beyond repair as a direct result of the panel installation.
B.
Repair panels with minor damage as acceptable to the Architect.
C.
Remove masking (if used) as soon as possible after installation.
D.
Ensure weep holes and drainage channels are unobstructed and free of dirt and sealants.
3.4
PROTECTION
A.
Protect installed products until completion of project.
B.
Touch-up, repair or replace damaged products before Substantial Completion.
