2.5
GLASS AND GLAZING
**************************************************************************
NOTE: Coordinate project window requirements with
aluminum window manufacturer's "standard" glass for
windows and Section 08800 GLAZING. Inside glazing
should be specified but may not be available for
double-hung windows; verify with manufacturer's
data. Double-glazing may be used in accordance with
TI 800-01 Design Criteria. When double-glazing is
used, specify "Thermal Performance" indicated in
paragraph under "WINDOW PERFORMANCE".
**************************************************************************
Aluminum windows shall be designed for inside glazing, field glazing, and
for glass types scheduled on drawings and specified in Section 08800
GLAZING. Units shall be complete with glass and glazing provisions to meet
AAMA 101. Glazing material shall be compatible with aluminum, and shall
not require painting.
2.6
FINISH
**************************************************************************
NOTE: Anodic coatings and baked-acrylic resin-based
coatings are typically used for economic reasons.
High-performance fluoropolymer coatings may cost
more than anodizing or resin-based coatings but is a
very durable coating with excellent colorfastness.
For a broader selection, refer to Aluminum
Association AA DAF-45 publication "Designation
System for Aluminum Finishes" which establishes a
wide range of coatings and colors. Omit the
non-applicable paragraphs below.
**************************************************************************
2.6.1
Anodized Aluminum Finish
**************************************************************************
NOTE: The 0.010 mm (0.4 mil) thick anodized finish
costs less than, but is more easily scratched and
not as durable in appearance and performance as, the
0.02 mm (0.7 mil) thickness.
**************************************************************************
Exposed surfaces of aluminum windows shall be finished with anodic coating
conforming to AA DAF-45: [Architectural Class II, AA-M10-C22-A31, clear
anodic coating, 0.010 to 0.02 mm 0.4 to 0.7 mil thick, 204-R1 Natural
Color] [Architectural Class I, AA-M10-C22-A41, clear anodic coating, 0.02
mm 0.7 mil or thicker, 215-R1 Natural Color] [Architectural Class I,
AA-M10-C22-A44, color anodic coating, 0.02 mm 0.7 mil or thicker]. Finish
shall be free of scratches and other blemishes.
2.6.2
Baked-Acrylic Resin-Based Coating
Exposed surfaces of aluminum windows shall be finished with acrylic
resin-based coating conforming to AAMA 2603, total dry thickness of 0.03 mm
1.0 mils. Finish shall be free of scratches and other blemishes.
