We know that the final appearance of your building is influenced by the fixing method you choose. Fixing is not simply a technical requirement but is vital to achieving your vision.

There are many types of fixings that can be used with our Rockpanel boards:

  • visible (screws and rivets)
  • semi visible (nails)
  • hidden fixing (glue)

The advantage of Rockpanel Lines² is that it can be fixed safely using traditional nails or screws or by using the innovative Rockpanel clip for that ‘invisible’ look, requiring no pre-drilling or special tools.

Rockpanel Lines² 10 on Timber

Traditional fixing of Rockpanel Lines² 10 on a timber sub-frame

The Rockpanel Lines² 10 tongue-and-groove panels can be fixed invisibly, which results in an attractive traditional groove effect, using:- Rockpanel ring shank nails (EN10088, material nr. 1.4401 or 1.4578) 2.1/2.3 x 27mm with an ultra-flat head. For an even better result we recommend pre-drilling of the tongue with a steel drill Ø 3 mm on the edges and Ø 2 mm in the middle of the board.- Stainless steel flat-top screws 3.5 x 30 mm. The tongue should be pre-drilled with a steel drill Ø 3.5 mm on the edges and Ø 2.5 mm in the middle of the board and the hole for the flat-top screw head should be sunk with a countersink drill bit. The top of the screw head should be level with the surface of the tongue. Tension in the mounting of the tongue can be avoided by torqueing the screw to a set limit and by ensuring they are driven in to the batten correctly.

In collaboration with Bostik, a fire safe European-certified adhesive fixing system called Rockpanel Tack-S has been developed. The system is compliant with the strict fire-safety rules of exterior cladding systems. With Rockpanel Tack-S your boards can be bonded safely, reaching a fire-class of B-s2,d0, onto a

  • timber sub-frame using a Rockpanel strip

or onto an

  • aluminium sub-frame

Follow the instructions provided by Bostik in order to secure your Rockpanel boards safely. If you prefer to use another adhesive system always verify with the system supplier whether this is technically approved and guaranteed for bonding Rockpanel boards.
