When Rockpanel boards are fixed mechanically,
- use Rockpanel fixings on an aluminium or timber sub-frame
- ensure the fixings are free of tension
When determining the fixing distances keep in mind the following:
- wind loading
- Determine the fundamental local basic wind velocity
- Determine the maximum height of the building
- Determine the site altitude
- Determine the distance from the coast
- Determine the distance to the edge of the city - the building area (see image below)
- type of Rockpanel board, thickness and fastening system
- the required ventilation provisions
- static load absorption, for example 1-field- or 2-field span
- legal local requirements
