The roofing assembly / material information published below and in the RCABC Roofing Practices Manual 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. For more information about this product or system, consult the manufacturer.

OVERVIEW

The Knudson KR-21 VP Varipan standing seam panel is formed with an on-site/in shop continuous metal roofing panel roll forming machine ( New Tech SS Multipro ). This machine produces a standing seam panel with a seam height of 38 mm (1 1/2") and profiles can vary from 305mm (12") wide up to 500 mm (20") wide.

On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to 300'.

SYSTEM DESCRIPTION

  1. General: The Knudson KR-21 VP Varipan is standing seam concealed fastener roof panel. The maximum spacing of screws in the built in nailing strip is 635mm (24")
  2. Range of application: Installed on wood or steel sloped roofs, in commercial, institutional, industrial and residential construction. For re-roofing or new construction.
  3. Panel Attachment: Fastening is site specific, engineer must confirm fixing specifications.
  4. Fasteners (Screws): Fasteners used to attach panel clips to steel must be No. 10-16 by 25 mm (1") long self-drilling, self-tapping pancake head plates steel screws. Use two fasteners per panel clip, inserted into panel clip guide holes.
Fasteners used to attach panel clips to plywood must be No. 10-16 by 25 mm (1") long pancake head plated steel screws for wood. Use two fasteners per clip, inserted into panel guide holes.
  1. Panel Clips: One piece assembly 38 mm (1-1/2") wide, 47 mm (1-5/8") high, manufactured by Knudson (or approved equal). Minimum thickness 0.022 in. (No. 22 MSG). Clips spaced maximum 600 mm (24") O.C.
