A quick guide to fixing and fixing distances

Fixing a Rockpanel board couldn’t be easier, but there are a few guidelines to follow

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

The calculated maximum fixing distances for the Rockpanel exterior cladding boards and maximum building heights for Rockpanel Lines² are based on the following characteristics:

  • Rockpanel boards in Durable grade
  • Location in country
  • Distance from the coast > 10 km
  • Site altitude ≤ 50 m
  • Building height ≤ 10 m (only applicable for Rockpanel Boards)
  • Strength class timber: c24 according EN338
  • Aluminium according ETA
