Challenge nature, defy gravity
Rockpanel Stones
Since visionary architecture has always disregarded limitations – why not challenge nature itself? With Rockpanel Stones, gravity appears to have been outsmarted. Let yourself be inspired by the astonishing characteristics of this natural material and incorporate the impressive versatility of Rockpanel Stones in your creative planning.
Material and use
The Rockpanel 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 cladding boards are suitable for use as exterior cladding, applications along the roofline and for building detailing.
The boards are treated with a 4-layer water-based high quality coating that locks in their appearance, colour and finish for years to come. Plus the whole range is finished with an additional protective ProtectPlus layer.

ProtectPlus, extra protection
Rockpanel Stones comes with a transparent ProtectPlus layer as standard, the most powerful protective layer for Rockpanel board material.
The benefits of the ProtectPlus finish are:
Self-cleaning
UV-protection
Anti-Graffiti
Because of its composition, our boards offer excellent properties when compared with traditional building materials such as:
wood, fibre cement board (FCB) and High Pressure Laminate (HPL) board material.
Unique composition and properties
Creating fire-safe buildings to protect the people living and working inside is an increasingly important issue. With Rockpanel FS-Xtra we developed an exterior cladding board which meets the European fire class A2-s1, d0 (non-combustible according to national building regulations) when fixed on a metal sub-frame with rivets. Next to that we offer the Durable grade, which is classified as B-s2, d0. When using Rockpanel boards you can create façades with a high level of fire safety with a broad range of aesthetic finishes.
| Property | Value |
| Fire Classification (Euroclass) | EN 13501-1 |
| - Rockpanel Durable | B-s2, d0 |
| - Rockpanel FS-Xtra | A2-s1, d0 |
If you are looking for a truly unique façade with a personal touch, you have the option to engrave Rockpanel boards with your own creative design – corporate logos, text, graphic images – the only limit is your creativity! Designs can be made with a CNC router on a 10mm thick board (maximum engraving depth of 2mm). A further advantage of engraving on Rockpanel boards is that the engraved parts don’t need any additional protection.
Rockpanel boards can be curved and bent easily to create amazing facades.
