General Considerations

The following is a summary of conditions and considerations that we consider important to the design and specification of PAC-CLAD PANEL projects. For more specific information concerning your projects, please contact us directly on our technical service line: 1-800-PAC-CLAD. We will gladly provide you with any additional information you may need.

Finishes

PAC-CLAD PANELS are available as standard with a full strength Kynar 500¿ or Hylar 5000¿ finish. Please refer to the color chart on page 7 for color selection. Samples and photo-accurate color charts are available for your assistance. Other finishes available include PAC 300 Clear and PAC 500 Bronze anodized coatings; Siliconized polyester and acrylics.

Special Colors

Special colors are available for most applications of greater than 15,000 square feet and may be applied to either aluminum or G-90 galvanized steel. Contact Petersen for information concerning relative costs and availability.

Installation

Special care must be taken to insure that panels are installed over a flat substrate. For roofing applications, panels typically must be installed over 5/8" or 3/4" plywood decking with 30# roofing felt (minimum)horizontally overlayed from eave to ridge. It is recommended that clips be installed on 18" centers for all applications except Snap-Clad (consult specific UL Construction assemblies for clip spacing). Consult a local architect/engineer for requirements of local codes and conditions.

Accessories

Most applications require additional metalwork including fascia, storefront trim, copings, gravel stops, downspouts, etc. Such metalwork may be specified for fabrication by manufacturer or for fabrication from flat sheet as provided by manufacturer. Flashings fabricated from PAC-CLAD flat sheet are fully covered under Petersen's 20 year finish warranty. PAC-CLAD flat sheet provides an exact color match to PAC-CLAD PANELS.

Lengths

All panels are custom cut-to-length before roll-forming and are available in lengths up to 40'. Minimum length is 4'-0". Lengths are accurate to 1/4". Custom cut-to-length is available at no up-charge and helps to improve project economy. Consult factory for lengths over 40 feet.

Panel Widths

Most of our PAC-CLAD Panels are available in non-standard on-center dimensions. Contact Petersen Aluminum for product availability and cost.

Pitch

SNAP-CLAD Panels have been designed to be installed on applications as low as 2:12 pitch. Integral Panels and Snap-On Panels have been designed for a minimum 3:12 pitch. Greater pitch may be required in snow country and in areas of extreme climate conditions.

Fire Ratings

PAC-CLAD Panels have been evaluated by Underwriter's Laboratories for inclusion in a variety of fire-rated ╥P-Assemblies" and are classified in section CETW of the UL Fire Resistance Directory - Vol. 1. Several panel assemblies have been evaluated as Class A fire rated. Contact PAC for complete information on components and assemblies.

Oil Canning

All Petersen material is prime quality aluminum and G-90 galvanized steel. All materials used are specified for roll-forming

applications and are, as such, stretcher and tension leveled. Panels are inspected in the plant for flatness before shipment. Job-site conditions such as temperature variation, unlevel substrate and/or improper installation may aggravate this condition. Oil canning does not affect the finish or structural integrity of the panel and is therefore not cause for rejection.

Warranty

A full twenty year warranty is available covering cracking, peeling and color fade on all PAC-CLAD applications. PAC-CLAD is a full Kynar 500¿ or Hylar 5000¿ finish and is, therefore, the highest quality 20 year non-prorated finish available. Full test results and SPEC-DATA¿ information are available from Petersen.

Storage

Materials should be stored in a clean, dry place. Suitable facilities for storage and protection of material should be provided at the job-site. Store materials out of traffic areas to prevent dents, bending, abrasion, etc.

Limitations On Liability

Neither Petersen Aluminum Corporation nor its customer shall be liable for special, indirect, or consequential damages. The liability of Petersen Aluminum Corporation in the event of the sale of its products shall be limited to replacement of any defective or nonconforming products or refund of the purchase price.
