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 Resolite®

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 [.63” (16 mm single panel with exposed interlocking “U” battens 30mm thick in polycarbonate, aluminum, or steel.

Panel Width – Shall not exceed 2’ (600 mm) to ensure best performance for wind uplift, vibration, oil canning and visual appearance. Panels over 2’ wide will not be approved.

Thermal and Solar Performance
1. Thermal Transmission value per ASTM C 518 shall Be__________.
2. Light Transmission (L.T.%)_________ Per ASTM D1003.
3. Solar Transmission (S.T.) _________________
4. Color: ______________________

Translucent Panel Joint System
Panel shall be extruded in one single formable length. Maximum panel width shall not exceed 2’. Transverse connections are not acceptable.

The panels shall be manufactured with a grip lock single tooth upstands that are integral to the unit. The upstands shall be 90 degrees to the panel face. Welding or gluing of upstands or standing seam is not acceptable.

The “U” battens shall have a grip lock single tooth locking mechanism to ensure maximum uplift capability.

The metal retention clip (hook) must be tested to meet a wind uplift standard of 90 PSF per ASTM E 330-97.

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.

Flammability

METAL FRAME STRUCTURE
To meet ANSI/ASCE 7-95 building design load, design criteria shall be:
Wind 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.
