Fire safety you can trust

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.

Sustainability and environment

Rockpanel boards have a third-party verified Environmental Product Declaration (EPD), in all according to the EN15804, where we transparently communicate the environmental performance of our products.

The influence on air quality and release of dangerous substances to soil and water has been determined to achieve the European Technical Assessment. The analysis showed Rockpanel boards contain no dangerous materials such as biocides; the manufacture of Rockpanel boards does not involve the use of flame retardants or cadmium. The formaldehyde concentration is ≤ 0.0105 mg/m³ which relates to formaldehyde class E1.

Award-winning sustainable home in Germany

There are many ways to build a smart and sustainable home. The architects at Cousin Architekt opted for an efficient, modular construction method for a new residential home in the German region of Soltau. The timber frame that forms the basis of the house can be completely dismantled. In addition, only ecologically and biologically suitable materials were used. Rockpanel Colours and Rockpanel Lines² were chosen as façade cladding because of their sustainable nature and excellent fire-resistant properties.
