Fixing guidelines ROCKPANEL boards

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
    - 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 figure below
  • type of ROCKPANEL board, thickness and fastening system
  • the required ventilation provisions
  • unimpeded movement of the boards
  • static load absorption, for example 1-field- or 2-field span
  • legal local requirements

For processing and fixing of ROCKPANEL Natural and ROCKPANEL Lines² there are some additional requirements and guidelines to be aware of.

The calculated maximum fixing distances for the ROCKPANEL board material and maximum building heights for ROCKPANEL Lines² are based on the following characteristics:

  • ROCKPANEL Durable boards;
  • 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 approval.

General

Building area:

A = Corner area
B = Area between the corners
h = Total building height

Basic wind velocity

The map below can be used as indication for the fundamental basic wind velocity according to BE-EN 1991 1-4. If you are unsure on the exact zone the building is located in, please contact ROCKPANEL.
