PAC-3000 CS

PAC-3000 CS is the caulk joint composite wall panel system of the PAC-3000 family from PAC-CLAD | Petersen. It is a rout-and-return wet system: an engineered assembly of composite panels with clips, trim and flashings, whose joints are sealed with sealant over backer rod. Each fabricated panel is individually adjustable, and staggered angle clips support its installation and alignment. It is used as composite metal wall panel cladding.

The face and back skins are 0.020 inch, bonded to a polyethylene or fire-retardant core. Panel properties are:

• Panel type: Reynobond ACM with the standard fire-rated (FR) core, designation RB160FR.
• Thickness: 4 mm, 0.157 in.
• Weight: 1.53 lbs per square foot.
• Face sheets: 0.020 in. aluminum, 3000 series or equivalent.

Materials in the CS family include 3 mm, 4 mm and 6 mm composite, .063 to .125 inch mill finish aluminum, zinc, stainless steel and anodized aluminum. Welded corners are available.

The CS section shows composite panels of 3 mm or 4 mm fixed to a plywood substrate over a vapor barrier. Attachment clips take 10-16 x 1 inch Tek 3 fasteners, and a continuous factory-applied aluminum extrusion forms the composite track, with a 1 inch typical joint and continuous backer rod at the sealed joint.

The finishes are a wide variety of non-PAC-CLAD colors; PAC-CLAD colors carry an extra fee. The composite coating is a coil-applied Kynar 500 or Hylar 5000 PVDF finish with a 0.2 mil prime coat and a 0.8 mil finish coat of 70 percent Kynar 500 resin. Salt spray resistance passes 4,000 hours (ASTM B117) and humidity resistance passes 4,000 hours (ASTM D2247). Exterior exposure is 10 years at 45 degrees in South Florida with a maximum fade of 5 and chalk of 8. The paint meets AAMA 620.

The composite material manufacturer warranty is 20 years against fade, chalk and delamination. The installer warrants fabrication and installation workmanship for 1 year.

• ASTM E330: 60 psf design pressure with no deformation or failure of structural members; maximum span deflection L/60.
• ASTM E283: not more than 0.06 cfm per square foot at 1.57 psf.
• ASTM E331: no water penetration at 6.24 to 12.0 psf static pressure.
• AAMA 501: no uncontrolled water leakage at 10.00 psf dynamic pressure.

The ASTM tests apply to the composite material only. ASTM E84 Class A and NFPA 285 are passed. Peel strength is 40 in-lb per inch under ASTM D1781, both as manufactured and after 21 days in water at 70 degrees F.

Fabrication is by rout and return, with a protective film left on the finished face during fabrication, shipping and erection. Sealants and gaskets follow the manufacturer's standards. Flashing is aluminum of 0.040 inch minimum thickness, and post-painted spray-applied flashings are not accepted. Dissimilar metals are separated with gaskets and suitable fasteners.

Panels are formed by a rout-and-return process on computer-controlled routing equipment, and welded corners are available. Staggered angle clips are mounted to the panel, so each panel can be installed and adjusted individually. The skin options run from .063 to .125 mill finish aluminum, zinc, stainless steel and anodized aluminum, alongside the 3 mm, 4 mm and 6 mm composite.

Colors in the PAC-CLAD color guide do not apply to composite panels. The panels are offered in a wide range of finishes and colors from the composite-panel offering.

Published details cover the outside corner, inside corner, and horizontal and vertical joints, with PDF and CAD drawings for a wood substrate (door jamb, jamb, parapet, sill, soffit, window head and sill, and window jamb conditions). BIM files exist for the PAC-CLAD 3000-CS Composite Wall Panel. The related systems are the PAC-3000 RS rain screen and the PAC-4000 RV and DRV field-assembled systems.
