Surface

The surface of Rockpanel boards is treated with layers of water-borne polymer emulsion primer and paint on one side. An additional ProtectPlus coating comes standard with Rockpanel Metals, Chameleon, Stones and Woods. This ProtectPlus layer makes the board extremely easy to clean; even graffiti can be washed off. ProtectPlus is available as an option for the Rockpanel Colours boards.

Fire Safety

Rockpanel 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. As a result, the addition of environmentally unfriendly flame retardants is not needed. The Rockpanel products are tested in accordance with the European harmonized technical specification (EAD 090001-00-0404 and EAD 090001-01-0404) and are classified in accordance with EN 13501-1. The Euroclass classification of all Rockpanel products is based on testing with non-combustible mineral wool insulation. For the field of application covered by the classification, please see the relevant Declaration of Performance. For high-rise and high-risk buildings, Rockpanel recommends the application of non-combustible (Euroclass A1-A2- s1,d0) cladding and insulation.
