CENTRIA 07 42 13 Metal Wall Panels of 18

CENTRIA IW SeriesTM Metal Wall Panels

CENTRIA IW SERIESTM Concealed Fastener Metal Wall Panels are a versatile design choice for both new and retrofit projects. Panels are available with hot-dip galvanized, Galvalume®, or Galvalume Plus®

coated steel and aluminum and stainless steel substrates. They are manufactured with a variety of

profiles and surface treatments; and are available in over 60 standard colors plus custom colors.

CENTRIA IW SeriesTM Metal Wall Panels coated with CENTRIA's own Fluorofinish® Kynar 500® or Hylar

5000®-based fluoropolymer or Versacor® corrosion- and abrasion- resistant finishes will last for decades. Highly UV resistant and durable in the face of chemical and air borne pollution, salt spray and wind-

driven sand, CENTRIA coatings set the standard for the industry. IW Series Metal Wall Panels are

available in over 60 standard colors and additional custom colors.

CENTRIA Metal Wall Panels are used in both horizontal and vertical configurations, and are available with

a factory-installed sealant in the side joint to help minimize water intrusion. They may serve as the exterior cladding components of an overall wall assembly that includes CENTRIA MetalWrap® insulated

composite metal backup panels that provides an insulated substrate complete with moisture, air, and vapor control.

CENTRIA Microline extrusions offer the designer an integrated trim system that ensure aesthetic control

over the profile of visual components of the wall assembly. CENTRIA MicroSeam® mitered trimless corners accentuate horizontal lines.

Specifier: Retain one, two, or three following paragraphs as appropriate to Project.

C. Framing: Inspect framing that will support metal wall panels to determine if support components are installed as indicated on approved shop drawings. Confirm presence of

acceptable framing members at recommended spacing to match installation requirements of metal wall panels.


D. Openings: Verify that window, door, louver and other penetrations match layout on shop

drawings.

E. Air/Moisture Barriers: Confirm that work has been completed, inspected, and tested as

required.

F. Advise G.C., in writing, of out-of-tolerance work and other deficient conditions prior to

proceeding with metal wall panel system installation.

G. Correct out of tolerance work and other deficient conditions prior to proceeding with panel installation.

3.2 SECONDARY FRAMING INSTALLATION

Specifier: Retain article if secondary framing is part of work of this Section.

A. Secondary Metal Subgirt Framing: Install secondary metal framing components to tolerances indicated, as shown on approved shop drawings. Install secondary metal framing and other

metal panel supports per ASTM C 1007 and metal wall panel manufacturer's recommendations.

3.3 METAL WALL PANEL INSTALLATION

A. General: Install metal wall panels in accordance with approved shop drawings and

manufacturer's recommendations. Install metal wall panels in orientation, sizes, and locations indicated. Anchor metal wall panels and other components securely in place. Provide for

thermal and structural movement

requirements of Division 07 Section "Insulated-Composite Backup Panel System."

B. Attach panels to metal framing using recommended clips, screws, fasteners, sealants, and

adhesives indicated on approved shop drawings.

1. Fasteners for Steel Wall Panels: Stainless-steel for exterior locations and locations

exposed to moisture; carbon steel for interior use only.

2. Fasten metal wall panels to supports with fasteners and spacing recommended by manufacturer.

3. Provide weatherproof escutcheons for pipe and conduit penetrating exterior walls. 4. Dissimilar Materials: Where elements of metal wall panel system will come into contact

with dissimilar materials, treat faces and edges in contact with dissimilar materials as

recommended by manufacturer.

C. Joint Sealers: Install joint sealants where indicated on approved shop drawings.
