PART 2 PRODUCTS
TRANSLUCENT INSULATING INTERLOCKING POLYCARBONATE GLAZING AND SYSTEM: BDL® 16mm-HD4
The design and performance criteria of this project are based on products manufactured by CO-EX Corporation, Wallingford, CT,
(203) 679-05090 and (800) 888-5364, Fax (203) 679-0600,
Substitute products must be proven equal and approved by addenda prior to the published bid date.
TRANSLUCENT PANEL PERFORMANCE
APPEARANCE – Panel assembly thickness shall be a minimum 1.57” (40mm)
PANEL WIDTH– Shall not exceed 20.86" (530 mm) to ensure best performance for wind uplift, vibration, oil canning and visual appearance.
AIR INFILTRATION: Must meet standard of ASTM D 283 at test pressure of 12 PSF – 0.06 SCFM per linear ft. of panel “U” joint connection.
WATER PENETRATION: No water penetration of the panel “U: connection length at a test pressure of 12.0 PSF per ASTM E 331.
Free movement of the panels shall be allowed to occur without damage to the weather tightness of the completed system.
Fire certifications available and subject to limitation on weight, colors, etc. Please contact CO-EX Corporation 1-800- 888-5364 for further information.
The panel shall not change color more than 5.0 units (DELTA-E BY ASTM D 2244) after 60 months outdoor weathering in Arizona determined by an average of at least two samples.
THERMAL AGING – the interior and exterior faces shall not change color in excess of 0.75 Delta E by ASTM D 2244 and shall not darken more than 0.3 units (Delta L by ASTM D 2244) and 0.2 units Delta Y by ASTM D 1925 and shall not show cracking or crazing when exposed to 300 degrees F for 25 minutes.
Panels shall consist of a polycarbonate resin with a permanent, co-extruded, ultra-violet protective layer. Post- applied coatings of films of dissimilar materials are unacceptable. Fiberglass faces (FRP) are unacceptable.
Panels shall have a factory applied ventilated tape at the sill to restrict dirt ingress.
METAL FRAME STRUCTURE
To meet ANSI/ASCE 7-95 building design load, design criteria shall be:
Wind Load _____________PSF
Snow Load _____________PSF
The Skylight framing is designed to be self-supporting between the support constructions. The deflection of the structural framing members in a direction normal to the plane of the glazing, when subjected to a uniform load deflection shall not exceed L/60 for the unsupported span. The skylights will impose reactions to the support construction. All adjacent and support construction must support the transfer of all loads including horizontal and vertical, exerted by the skylights. Design or structural engineering services for the supporting structure or building components not included in the scope are not included under this section.
Extruded Aluminum shall be ANSI/ASTM B 221; 6063-T6; 6063-T5 or 6005-T5.

Sheet metal flashings/closures/claddings are to be furnished shop formed to profile when lengths exceed 10 ft. in nominal 10 ft. lengths. Field trimming of the flashing and field forming the ends is necessary to suit as-built conditions. Sheet metal ends are to overlap at least 6” to 8”, set in a bed of sealant and riveted as required.
All fasteners for aluminum framing to be stainless steel or cadmium plated steel, excluding the final fasteners to the building.
All exposed aluminum shall be (Clear Anodized) (Color Anodized) of Standard Kynar 2 or 3 coat finish, or (other).
PART 3 EXECUTION
