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

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")
Range of application: Installed on wood or steel sloped roofs, in commercial, institutional, industrial and residential construction. For re-roofing or new construction.
Panel Attachment: Fastening is site specific, engineer must confirm fixing specifications.
Fasteners (Screws):
1. 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.
2. 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.
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.
Deck Requirements: in keeping with the Standard for Architectural Sheet Metal (ASM) Systems.
