Create an extraordinary and surprising perception to your building

Ever changing, ever evolving


Take a look from ever angle, it’s never the same twice – that’s the power of the ever changing ROCKPANEL Chameleon cladding board. Affected by natural light or artistic spots and the angle and height viewed – your vision becomes an eye catcher, ever changing and always inspiring.

Material and use

The ROCKPANEL Chameleon 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 external cladding 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 range is finished with an additional protective ProtectPlus layer.

Getting great grades

ProtectPlus, extra protection

ROCKPANEL Chameleon comes with a transparent ProtectPlus layer as standard, the most powerful protective layer for ROCKPANEL board material.

The benefits of the ProtectPlus finish are:

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

Take no risks - be on the (fire-)safe side

Creating fire-safe buildings to protect the people living and working inside is an increasingly important issue. With the ROCKPANEL FS-Xtra grade 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.

Add your personal signature

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.
