GENERAL INFORMATION
FIELD CONDITIONS
All material to be installed must be plumb, level and true. Aluminum to be placed in direct contact with masonry
or incompatible material should be isolated with a heavy coat of zinc chromate, bituminous paint or non-metallic
material.
After sealant is set and a representative amount of the wall has been glazed (250 square feet or more), run a
water hose test in accordance with AAMA 501.2 specifications to check installation. On large projects the hose
test should be repeated during the glazing operation.
CLEANING MATERIALS
Cement, plaster terrazzo, alkaline and acid based materials used to clean masonry are very harmful to finishes.
Any residue should be removed with water and mild soap immediately or permanent staining will occur. A spot
test is recommended before any cleaning agent is used.
EXPANSION JOINTS
Expansion joints and perimeter joints shown in these instructions and in the shop drawings are shown at
nominal size. Actual dimensions may vary due to perimeter conditions and/or differences in metal temperature
between the time of fabrication and the time of installation. For example, a 12 foot unrestrained length of
aluminum can expand or contract 3/32” over a temperature change of 50º F. Any movement potential should be
accounted for at the time of the installation.
