Fixing guides
When fixed mechanically Rockpanel boards must be assembled with Rockpanel fixings on a suitable subframe (aluminium rail support or timber frame) and free of tension. When determining the subframe the following should be kept in mind:
- wind loading
- the maximum fixing centres for the boards
- the required ventilation provisions
- unimpeded movement of the boards
- legal local requirements
In the table below you will find the designloads for the strength of the fastener [N], the values are to both mechanical and non-mechanical fixing.
 | Panel thickness = 8 mm ar1 = 15 mm ar2 = 50 mm Location of the fastening: M = Middle of the panel E = Edge of the panel C = Panelcorner |
| Max. distance c.t.c. (mm) | Maximum designloads* (N) | ||||
