<br />A. Exposed -Fastener, Lap -Seam Metal Wall Panels: Factory -formed, designed to be field assembled by lapping side edges of adja-
<br />cent panels and mechanically attaching panels to supports using exposed fasteners in side laps. Include accessories required for
<br />weathertight installation.
<br />1. Manufacturers:
<br />a. Berridge Manufacturing Company.
<br />b. MBCI; Div. of NCI Building Systems.
<br />C. Petersen Aluminum Corporation.
<br />d. Reynolds Metals Company.
<br />2. Profile: Tapered rib or as indicated on Drawings.
<br />3. Material: Metallic -coated steel sheet, 0.0159 inch.
<br />a. Exterior Finish Pre -finished to color indicated on drawings.
<br />b. Color: Match Architect's samples where applicable.
<br />2.6 ACCESSORIES
<br />A. Wall Panel Accessories: Provide components required for a complete metal wall panel assembly including trim, copings, fasciae,
<br />mullions, sills, corner units, clips, flashings, sealants, gaskets, fillers, closure strips, and similar items. Match material and finish
<br />of metal wall panels, unless otherwise indicated.
<br />1. Closures: Provide closures at eaves and rakes, fabricated of same metal as metal wall panels.
<br />2. Closure Strips: Closed -cell, expanded, cellular, rubber or crosslinked, polyolefin-foam or closed -cell laminated polyethyl-
<br />ene; minimum 1-inch- thick, flexible closure strips; cut or premolded to match metal wall panel profile. Provide closure
<br />strips where indicated or necessary to ensure weathertight construction.
<br />B. Flashing and Trim: Formed from 0.0179-inch- thick, metallic -coated steel sheet. Provide flashing and trim as required to seal
<br />against weather and to provide finished appearance. Locations include, but are not limited to, bases, drips, sills, jambs, corners,
<br />endwalls, framed openings, rakes, fasciae, parapet caps, soffits, reveals, and fillers. Finish flashing and trim with same finish
<br />system as adjacent metal wall panels.
<br />2.7 FABRICATION
<br />A. General: Fabricate and finish metal wall panels and accessories at the factory to greatest extent possible, by manufacturer's stan-
<br />dard procedures and processes, as necessary to fulfill indicated performance requirements demonstrated by laboratory testing.
<br />Comply with indicated profiles and with dimensional and structural requirements.
<br />B. Sheet Metal Accessories: Fabricate flashing and trim to comply with recommendations in SMACNA's "Architectural Sheet Metal
<br />Manual" that apply to the design, dimensions, metal, and other characteristics of item indicated.
<br />C. Protect mechanical and painted finishes on exposed surfaces from damage by applying a strippable, temporary protective covering
<br />before shipping.

<br />3.1 PREPARATION
<br />A. Substrate Board: Install substrate board over wall sheathing on entire wall surface. Attach with substrate -board fasteners.
<br />1. Install substrate board with long joints in continuous straight lines, perpendicular to direction of metal wall panel seams with
<br />end joints staggered between rows. Tightly butt substrate boards together.
<br />2. Comply with UL requirements for fire -rated construction.
<br />B. Install flashings and other sheet metal to comply with requirements specified in Division 7 Section "Sheet Metal Flashing and
<br />Trim."
<br />3.2 METAL WALL PANEL INSTALLATION, GENERAL
<br />A. General: Install metal wall panels in orientation, sizes, and locations indicated on Drawings.. Anchor metal wall panels and other
<br />components of the Work securely in place, with provisions for thermal and structural movement.
<br />1. Field cutting of metal wall panels by torch is not permitted.
<br />2. Rigidly fasten base end of metal wall panels and allow eave end free movement due to thermal expansion and contraction.
<br />Predrill panels.
<br />3. Install screw fasteners in predrilled holes.
<br />4. Locate panel splices over, but not attached to, structural supports. Stagger panel splices and end laps to avoid a four -panel
<br />lap splice condition.
<br />5. Apply elastomeric sealant continuously between metal base channel (sill angle) and concrete, and elsewhere as indicated or,
<br />if not indicated, as necessary for waterproofing.
<br />6. Provide weatherproof escutcheons for pipe and conduit penetrating exterior walls.
<br />B. Metal Protection: Where dissimilar metals will contact each other or corrosive substrates, protect against galvanic action by paint-
<br />ing contact surfaces with bituminous coating, by applying rubberized -asphalt underlayment to each contact surface, or by other
<br />permanent separation as recommended by metal wall panel manufacturer.
<br />C. Joint Sealers: Install gaskets, joint fillers, and sealants where indicated and where required for weatherproof performance of metal
<br />wall panel assemblies.
<br />1. Seal metal wall panel end laps with double beads of tape or sealant, full width of panel. Seal side joints where recommended
<br />by metal wall panel manufacturer.
<br />2. Prepare joints and apply sealants to comply with requirements in Division 7 Section "Joint Sealants."
<br />3.3 ACCESSORY INSTALLATION
<br />A. General: Install accessories with positive anchorage to building and weathertight mounting and provide for thermal expansion.
<br />Coordinate installation with flashings and other components.
<br />l . Install components required for a complete metal wall panel assembly including trim, copings, corners, seam covers, flash-
<br />ings, sealants, gaskets, fillers, closure strips, and similar items.
<br />2. Comply with performance requirements, manufacturer's written installation instructions, and SMACNA's "Architectural
