- DESCRIPTION
- The Knudson KR-12 is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 500 mm (20") wide with a seam height of 38 mm (1.5").
On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to nominal 46 m (150').
- 1.1 GENERAL
- The roofing assembly / material information published 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.
- 1.2 SYSTEM DESCRIPTION
- .1 Standing seam panels employ a hidden fastening system for securement to a solid substrate. Panels are seamed together with a mechanical seamer.
- .2 Range of application: on wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for reroofing or new construction.
- .3 Panel Attachment
-
- Fasteners (Screws)
- For panel clip to steel attachment to be No. 12-16 by 22 mm (1") long self- drilling, self-tapping, hex-washer head plated steel screws used without sealing washers. Two fasteners per panel clip used, inserted into panel clip guide holes.
- Roof Deck Fastener (Panel clip)
- Two part assembly consisting of a No. 16 MSG min thick coated steel base approximately 47.6 mm (1-7/8") wide and 40.9 mm (1-5/8") long and a No. 22 MSG min thick coated steel upper tab section. Fastened 600 mm (24") on centre. Height 61 mm (2-7/16") min, 75 mm (3") max, width 108 mm (4-5/16") Knudson Manufacturing Inc. – “KR-24 Low-Floating Clip”, “KR-24 High-Floating Clip”OR

- 1.4 PERFORMANCE REQUIREMENTS
- Wind Uplift Standards: Engineered designs to resist wind uplift may refer to the British Columbia Building Code, Div. B, Appendix C, Table C-2 which lists various types of loads, including wind loads, for specific reference locations throughout the province. See also Guides and Notes (Wind Resistance) for a simplified calculation procedure. Regardless of the resources indicated here, the Design Authority is responsible to perform accurate wind load calculations and specify securement requirements.
- Materials:RoofStar (RGC) accepted metal panel systems shall be formed of steel conforming to the standards published in the Architectural Sheet Metal (ASM) Roof Standards.
