Rockpanel facade cladding

Product Description
The true beauty of a facade is sometimes quite puristic. Be brave – let the sun, wind and rain play their part. Without applying paint or surface sealer, Rockpanel Natural allows the elements to take an active role in your facade. Your building fits organically into its surroundings, in an interactive way from day one. When you're looking for a unique and innovative facade, Rockpanel Natural might just be exactly what you need.
Rockpanel Natural has quite an extraordinary feature: the boards change under the effects of the weather. The fresh yellowish green colour scheme turns into a velvety, slightly sparkling brownish red surface over time. The effect is similar to the way wood takes on a patina under the effects of the weather.

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.

Rockpanel Natural: a vibrant façade in harmony with nature
The German family-owned company BRUNNER, based in Eggenfelden, Bavaria, has specialised in the design and manufacture of high-quality stoves and fireplaces since 1946. The company's decision to also develop heating and boiler systems from 2010 onwards led to increasing space constraints and ultimately to the construction of a completely new production facility. The design by architect Prof. Markus Frank consists of two modern buildings with strikingly innovative and distinctive features – both inside and out. The striking exterior façade seamlessly reflects BRUNNER's forward-looking business activities.
