etalbond® Aluminium Composite Panel

The composite consists of essentially two layers of aluminium, each 0.5 mm thick, and a mineral core layer of 3 mm (2 mm and 5 mm also available on request).


Aluminium:

The aluminum used for the production of etalbond® is largely made from recycled raw materials, since aluminum can be reprocessed in the recycling process and made into new products without any loss of quality. An additional advantage of the manufacturer ELVAL COLOUR is that it is able to obtain aluminum strips from its own parent company ELVAL for the production of etalbond®. ELVAL is a casting and rolling mill in the direct vicinity, which avoids long transport routes and ensures complete traceability with regard to recycling.


Core layer:

The non-toxic core layer of etalbond® FR consists of min.70% mineral fillers and max. 30% polymer, the A2 core is min. 90% mineral filled and max. 10% polymer. Both of the polymer core and the aluminium sheets are recyclable and can be used in the production of new material.

Further details in the respective EPDs (environmental product declaration) are available on request:

EPD etalbond FR (B1 - flame retardant)
EPD etalbond A2 (A2 - non-flammable).


Durability:

etalbond® aluminum composite panels have been developed for long-term use on building facades or similar applications. The production of etalbond® started in 1996 and today there are still significant facades from the first years of production. Internationally, there are already positive empirical values of composite panel facades with a lifespan of more than 60 years. 


Recycling:

etalbond® can be fully recycled. In the recycling process, there are different ways of separating the composites, as shown in following illustration:

LEED, BREeAM, MINERGIE® and DGNB Enviromental Assessment Systems

Generally used for the purpose of sustainability assessment in buildings or neighborhoods and even economic and ecological issues, the various certification systems (national and international) are quantitative standards to measure the concept of sustainable development.

They focus on buildings in their construction or operatation phase and evaluate individually their environmental quality from quite similar aspects: impacts on ecosystems, impacts on climate change, impacts on hydrology and landscape, consumption of non-renewable energy resources, environmental aspects of used materials, quality of indoor building environment, construction and operation processes, etc.

There are precisely defined so-called credits or criteria for each certification, which, if fulfilled, equals  to assigned points or an overall score. The resulting "score" (for a LEED sum total, for a BREEAM summed weighted average) means achieving a certain level of rating; the DGNB System does not evaluate individual measures but the overall performance of a building based on criteria. The MINERGIE® eco-label focuses on highering the valuation of energy-conscious construction that pursues a superior living comfort.

According to the overall score or reached criteria, the building /project receives an evaluation as follows:

  • LEED scale is: Not certified, Certified - Silver - Gold - Platinum.
  • BREEAM scale is: Unclassified - Pass - Good - Very Good - Excellent - Outstanding.
  • DGNB scale: Certificate or Pre-Certificate - Bronze - Silver - Gold - Platinum.
  • MINERGIE® standards: Minergie, Minergie-P and Minergie-A. With the addition of ECO, MQS Bau, MQS operation and the "PERFORMANCE" fro larger buildings. 


All of the above mentioned assessments are commonly reviewed by an independent party. The results of these can be useful for different groups, e.g. national and local governments, users, planners, builders, owners, investors, etc.

etalbond® aluminium composite panels can contribute towards sustainable architecture and can aid with meeting the environmental requirements for eco-labels / certifications.
