Product Group: STANDING SEAM METAL ROOF SYSTEM – KNUDSON KR-12
- 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 1/2"). Panels are produced with two stiffening flutes.
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: Wood
- Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 762 mm (30") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #10 x 22 mm (1") long pancake head type A plated.
- Two piece assembly to be used for longer panel lengths, clip to be Knudson 22 ga 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre.
- Panel Attachment: Steel
- Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #8-16 x 22 mm (1") long self-drilling, self tapping wafer head, plated screws.
- Two piece assembly to be used for longer panel lengths, clip to be Knudson 22 ga 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre.
- 1.3 SITE CONDITIONS
- .1 Minimum roof slope is 1:6 (2" in 12"). Severe conditions (heavy snow or ice) minimum slope is 1:1.5 (8" in 12").
- 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.
