that conform to the following standards:
1. Structural: The design load / deflection criteria and fastening patterns in accordance with ASTM
E72.
a. The deflection criteria shall be L/180 for walls.
2. Air Infiltration: Air leakage shall not exceed 0.001cfm/sq. ft. of wall area at a pressure differential
of 20psf in accordance with ASTM E283.
3. Water Penetration: No uncontrolled water penetration through the panel joints at a pressure
differential of 20psf in accordance with ASTM E331.
4. Methods of Test for Exterior Walls in accordance with AAMA 501-94
5. Thermal Resistance:
a. Panels shall provide nominal thermal resistance of R=7.5 per inch of thickness in
accordance with ASTM C518.
b. Panels shall provide nominal thermal resistance of R=7.2 per inch of thickness in
accordance with ASTM C1363.
6. Fatigue: The panel shall withstand at least 2 million alternate cycles of L/180 deflection without
any evidence of delamination, foam core cracking or permanent deformation.
a. Positive wind pressure and negative wind pressure (suction) are continually bending
interior and exterior composite panels.
7. Freeze / Heat Cycling: Panels shall exhibit no delamination, surface blisters, permanent bowing or
deformation when subjected to cyclic temperature extremes of -20°F (-29°C) to +180°F (+82°C)
temperatures for twenty one (21), eight-hour cycles.
