Rockspan is a through-fix architectural wall panel system

Rockspan is an external composite wall panel, it's through fix joint detail enables simple and fast construction an ideal solution for large scale buildings.

  • The through fix joint detail and its single component through wall construction eliminates the requirement for wet trades and speeds up the construction process.
  • Rockspan can be installed both vertically and horizontally and can be finished with an external satin line or architecturally flat profile, suitable for a wide range of building designs.
Widths: From 600, 900, 1000, 1150 & 1200mm
Core Thicknesses: 75 to 300mm
Thermal Performance: U Value of 0.15 (W/m²K) can be achieved
Fire Performance: All systems use a high density stone wool core providing high fire performance requirements.

Fire Performance

Rockspan panels offer a Euroclass A2-s1, d0 Reaction to Fire when tested and classified to BS EN13501-1 when specified with Colorcoat Prisma® by Tata Steel.
Rockspan can offer up to 4 hours fire resistance (to EN 13501-2) to both insulation and integrity but should be technically verified by Eurobond on a project basis, to the correct standards.


As a responsible UK manufacturer, Euroclad Group is justifiably proud of it's environmental record and recognises the importance of sustainable construction.

Our philosophy is one of continual improvement and we strive to manufacture the most environmentally responsible products available whether that is through Life Cycle Assessment (LCA), implementation of Environmental Management Systems or the demonstration of a truly sustainable approach.


Panel Options

Rockspan Ultima offers the most comprehensive fire performance of the entire Eurobond panel range. Up to 4 hours fire resistance can be achieved through the combination of joint stitching and maximum core density (no stitching required for +200mm Rockspan Ultima). This comprehensive system encourages greater spanning capabilities and advanced sound reduction, without compromising on design freedom. It is available in both of Satin Line (Micro Rib) and Flat profile finishes.

Rockspan Extra is available in both a Flat and Satin Line (Micro Rib) profile finishes. Manufactured using a higher density core than Rockspan Lite®, Rockspan Extra® is able to provide up to 2 hours fire performance with increased acoustic performance and spanning capabilities.

Rockspan Lite is manufactured using the lowest density core of the Rockspan® range. The panel system achieves up to 90 minutes fire performance without the need for joint stitching. The lower density core offers increased thermal performance whilst maintaining spanning capabilities due to the structural nature of the stone wool insulation.


A large selection of colours are available for the Eurobond Panel range.

Utilises cutting edge three layer manufacturing technology to create an optimised, robust and chrome free pre-finished steel product. Designed to withstand the rigours of the external environment, versatile, lightweight and strong, Colorcoat Prisma® pre-finished steel is the ideal choice for your building envelope for exceptional UV performance and long lasting colour. The contemporary colour range includes a selection of natural metal colours, as well as a wide selection of inspired Matt shades such as Matt Metallics ideal for facade applications.
