Material and use

The Rockpanel Lines² boards are produced from compressed natural basalt, a sustainable and readily available volcanic rock and bonded with an organic binder from which all Rockpanel products derive their unique properties. The products combine the advantages of stone and workability wood. The tongue-and-groove panels are suitable for horizontal application in ventilated constructions while Lines² 10 can also be installed vertically. Please feel free to contact us to advise you with regard to a vertical installation.

Traditional or innovative fixing

Lines² S 10 / Lines² XL 10: Traditional fixing

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 with a ultra-flat head or stainless-steel flat-top screws.

Lines² S 8 / Lines² XL 8: Innovative fixing

To make the fixing of tongue-and-groove panels easier and safer, we developed an innovative clip. The clip ensures that the supporting structure is ventilated more effectively, reducing moisture retention and thus increasing the structure’s durability.

Flexible mounting using the Rockpanel clip

Choose between a fixed and demountable installation of Rockpanel Lines² S 8 and Lines² XL 8 tongue-and-groove panels. For demountable installation, the tongue-and-groove board is simply inserted into the clip so that each panel can be removed separately.

Advantages of the innovative installation

  1. To achieve an effective wall design, the working width used can be optimised to fit the height of the wall.
  2. Using the different lines options, different groove widths can be created, meaning even greater variation in the interplay of lines.
