Mineral Fibre Cladding

These prefabricated compressed mineral wool cladding boards with thermo-setting synthetic binders offer the longevity of stone and the added flexibility of being as easy to work with as wood, in one product. These unique properties result in highly durable, workable, and low maintenance cladding boards and are a direct alternative to fibre cement cladding panels.

In addition to the vast range of standard colours available (almost all RAL and NCS colours), these mineral fibre boards are also available in a range of special finishes such as Rockpanel Woods, Stone, Metallic and Chameleon - where the colour of the boards change depending on the viewers vantage point and the amount of natural light available. These flexible and robust boards can be applied easily and can even be shaped, curved and perforated.

The European Reaction to Fire classification system (Euroclasses) of all Rockpanel products is based on testing with non-combustible mineral wool insulation. For high-rise buildings and high-risk buildings, Rockpanel recommends the application of non-combustible (Euroclass A1-A2) cladding and insulation.

Testing and Installation

These cladding boards offer high performance when assessed for reaction to fire. Due to the nature of the stone wool fibres and the low binder content, the boards have a low calorific value, this means that they will hardly contribute to a fire when exposed.

The Rockpanel products are tested in accordance with the European harmonised technical specification (EAD 090001-00-0404) and are classified in accordance with EN 13501-1.

Mineral fibre cladding boards are lightweight and can easily be cut to size on-site using traditional cutting tools and their edges do not require sealing. They are quick to install with screws, nails, or in some cases adhesives, requiring no special tooling, meaning construction and installation costs are kept to a minimum.
