Complete Compiled Specification.pdf - Peck Ormsby Construction

B. Aluminum Extrusions:
1. Perimeter Extrusions
a. Alloy: AA-6063-T5
b. Color: Extrusion color shall be black painted Duracon.
2. Stiffeners
a. Alloy: AA-6063-T5
b. Color: Stiffeners shall have a mill finish.
C. System Sealants:
1. Sealants and gaskets within the panel system shall be per manufacturer's standards.
2. Sealant color shall be black.
D. Gaskets:
1. Gaskets shall be Santoprene or EPDM.
E. Flashings:
1. Fabricate flashing from 0.062” minimum thickness aluminum sheet. Where exposed to
view, finish to match adjacent panels. Provide lap strip under flashing at abutted
conditions; with lapped surfaces sealed with a full-bed of non-hardening sealant.
F. Fasteners:
1. Attachment of the panel system to the primary panel structural supports shall be made
using a Drill-Flex ! Fastener by ELCO Textron Inc.
2. Typical joinery shall be attached with concealed fasteners. When exposed fasteners
are required in isolated conditions, the fastener shall be obscured in the panel joinery.
2.03 FABRICATION
A. Fabricate panel units to dimensions indicated on the drawings based on an assumed design
temperature of +70 degrees F. Allow for ambient temperature range at time of fabrication and
erection.
B. Fabricate panels in sizes shown using composite aluminum panel material and perimeter
extrusion so that the panel thickness at the joinery is no more than 1.75". Completed panel
shall be properly fabricated and designed so that no restraints are placed on the panel, which
might result in excessive compressive skin stresses. The installation detailing shall be such
that the installed panels shall remain flat due to temperature changes and at all times remain
water and air-tight. Oil canning of panel surface is not acceptable.
C. Where practical, shop fabricate units ready for erection. If not shop assembled, pre-fabricate
components at the shop as required for proper and expeditious field assembly.
D. Design, fabricate, assemble, and erect wall panel units, to insure a weather tight system, as
required in this specification section.
E. Where drawings indicate, factory curve panels to required radii. Extrusions shall be factory
stretched formed to conform to panel curve.
F. Provide stiffeners secured to rear face of panels mechanically fastened to edge trim members,
with spacing as required by specific job wind loading.
