;<u>DESCRIPTION</u>
 
 
The high performance NORDIC CLIP roof is a universal panel. It can now be found virtually anywhere ... from Mansards, low slope roofs on large factories, eye-catching gables and corporate headquarters; all have found these roofs appealing. Most important, Nordic Clip roofs have the proven durability and quality necessary for schools and public buildings. It performs well on roofs with a minimum slope of 1:6 (2" in 12"). It requires butyl tape between laps on roofs with heavy snow loads.
 
 
Nordic clip is 24 ga. (.631 mm) and can be applied over steel, wood, or structural concrete deck with or without insulation using a proprietary hidden fastening system. You can order in a variety of colours with Kynar 500 paint system. Twenty year warranties are available depending on paint type. 
 
 
;<u>PART 1 - GENERAL</u>
 
 
The roofing assembly / material information published in the <b>RCABC <i>Roofing Practices Manual</i></b> DOES NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
 
 
1.1 <u>SYSTEM DESCRIPTION</u>
 
:.1 Metal panels employ a hidden fastening system for securement to a solid substrate. Nordic Clip design allows the panel seams to interlock without having to use a mechanical seaming device.
 
 
:.2 Range of application: on wood or metal sloped roofs and to vertical wall framing in commercial, institutional, industrial and residential construction; also used for roof recovering or roof replacement (retrofit) application.
 
 
1.2 <u>DELIVERY, STORAGE AND HANDLING</u>
 
:.1 Protect against damage and discoloration.
 
:.2 Handle panels with non-marring slings.
 
:.3 Do not bend panels.
 
:.4 Store panels above ground, with one end elevated for drainage.
 
:.5 Protect panels against standing water and condensation between adjacent surfaces.
 
:.6 If panels become wet, immediately separate sheets, wipe dry with clean cloth, allow to air dry.
 
 
1.3 <u>SITE CONDITIONS</u>
 
:.1  Minimum roof slope is 1:6 (2" in 12"). Minimum slope applicable only to roof installations utilising standard details. Severe conditions (heavy snow, ice, winds) will increase minimum slope.
 
 
1.4 <u>PERFORMANCE REQUIREMENTS</u>
 
:<u>Testing and Certification</u>
 
 
:.1 <u>Wind Uplift</u>:
 
 
::<b><i>Note:</i></b> RGC Guarantee Standards do not permit spaced purlins applications.
 
 
::24 ga. (.631 mm) panels rated UL Class 90 when installed over minimum 14 ga. (1.897 mm) steel purlins spaced 1500 mm (5' 0") o/c maximum. The roof panel manufacturer must also subscribe to Underwriters Laboratories&#8217; &#8220;Follow Up Service&#8221; assuring continuing product compliance with UL requirements.
 
 
:.2 <u>Air Infiltration</u>:  Panel (without insulation) to meet the following standard ASTM E283.
 
:.3 <u>Water Penetration</u>:  Panel to meet the following standard ASTM E 331
 
 
;<u>PART 2 - PRODUCTS</u>
 
 
2.1 <u>MATERIALS - PANELS</u>
 
 
:.1  Base Metal; Steel conforming to ASTM A-792 Grade E, minimum yield 80,000 psi, thickness 24 ga. (.631 mm).
 
:.2  Protective Coating: Zincalume conforming to ASTM A-792, AZ 150
 
:.3  Finish: Exterior finish includes a 0.2 mil (.005 mm) thick corrosion-resistant primer and a 0.9 mil (.02 mm) thick finish coat of Polyvinylidene Flouride (PVF2), full 70% Kynar 500 / Hylar 5000 for a total 1.0 mil (.025 mm) dry film thickness.
 
:.4  Colour: Manufacturer's standard selection 
 
::Custom colour as selected by Architect on request.
 
 
:.5  Configuration: Roof panels shall consist of integral standing seams with a rib height of 1-5/8" (40.63 mm) spaced 8" (200 mm) o/c, nominal panel width 16" (400 mm).
 
 
2.2 <u>ACCESSORIES</u>
 
:.1  Westform clip 20 ga. (.889 mm) steel clip, UL-90 rated (Construction #170). For direct application over rigid insulation on to a metal or wood deck.
 
:.2  Fasteners: Per manufacturer recommendation.
 
:.3  End Closures: Material to be weather proof, laminated, semi-rigid, cross-linked polyethylene foam, tightly fit to panel configurations.
 
:.4 <u>Sealant Options:</u>
 
::Caulking: Gunnable grade caulking, Single component Urethane caulk.
 
::Tape sealant: Butyl type mastic.
 
 
:.5  Flashing: Material, gauge and finish to match panels. Do not use lead or copper.
 
 
2.3 <u>FABRICATION</u>
 
:.1  Unless otherwise shown on drawings or specified herein, fabricate panels in continuous one piece lengths and fabricate flashings and accessories in longest practical lengths.
 
:.2  Roofing panels shall be factory formed. Field formed panels are not acceptable.
 
:.3  Turn roof panel upper ends at least 38 mm (1-1/2") up (bread panned) under flashing.
 
:.4  Where slope is less than (3" in 12"): Turn roof panel lower ends down at least 10 mm (3/8") where exposed and turn down into gutters.
 
 
;<u>PART 3 - EXECUTION</u>
 
3.1 <u>EXAMINATION - EXISTING CONDITIONS</u>
 
 
:.1  Verify that structural deck to receive panels is complete, in true plane, secure and otherwise properly prepared.
 
:.2  Prior to starting work, notify General Contractor about defects requiring correction.
 
:.3  Do not start work until conditions are satisfactory.
 
 
3.2 <u>PREPARATION - FIELD MEASUREMENTS</u>
 
:.1  Verify prior to fabrication.
 
:.2  If field measurements differ from drawing dimensions, notify Architect / Professional Engineer prior to fabrication.
 
 
3.3 <u>PROTECTION</u>
 
:.1 Treat, or isolate with protective material, any contacting surfaces of dissimilar materials to prevent electrolytic corrosion.
 
:.2 Require workmen who will be walking on roofing panels to wear clean, soft-soled work shoes that will not pick up stones or other abrasive material which could cause damage and discoloration.
 
:.3 Protect work of other trades against damage and discoloration.
 
:.4 Clean and dry surfaces prior to applying sealant.
 
 
3.4 <u>INSTALLATION - PANELS</u>

:.2 Install panel seams vertically.
 
:.3 Lap panels away from prevailing wind direction.
 
:.4 Do not stretch or compress panel side-lap interlocks.
 
:.5 Secure panels without warp or deflection.
 
:.6 Fully engage interlocking seams.
 
:.7 Extended roof panels to overlap gutter openings 50 mm (2"), but do not restrict opportunity to clean gutters.
 
:.8 Maximum alignment variation: 1/4" in 40' (6.25 mm in 12.31 m).
 
 
3.5 <u>FLASHING</u>
 
:.1 Follow manufacturer's directions, approved shop drawings and <i>RGC Guarantee Standards</i>.
