Our Cradle to Cradle certified products

A waste-free ecosystem: both a Reynaers Aluminium mission and the goal of the Cradle to Cradle Products Innovation Institute. We explain what the C2C circular certification means and which of our products carry this sustainable seal of approval.

The Cradle to Cradle (C2C) principle states that all materials and products within a production process belong to a continuous biological or technical cycle. In that sense, production components and the use of products should always focus on high quality and circularity. We discuss how this principle is applied within the building industry and at Reynaers Aluminium.

Cradle to Cradle CertifiedCM Products Standard

One real-life initiative concerning the C2C principle is the Cradle to Cradle CertifiedCM Products Standard. The sustainable certification system evaluates the circularity of materials and products, essentially resulting in a waste-free ecosystem. Its goal is to encourage innovation and the design of products that effectively and positively affect people and the environment.

The sustainability label evaluates products across five categories of human and environmental health:

  • Material re-utilisation – the recycling potential of components
  • Material health – the complete chemical composition of the product
  • Renewable energy – the product’s energy consumption and carbon emissions
  • Water consumption – and its impact on the environment
  • Social responsibility – the impact of the product on its community

Reynaers Aluminium C2C-certified products

The C2C label is only available for the most durable products and materials – including aluminium. Despite the strict requirements, quite a lot of Reynaers Aluminium window, door and curtain wall systems have been awarded the Cradle to Cradle CertifiedCM Bronze certification. A short overview:


  • MasterLine 8
  • ConceptSystem 77
  • ConceptSystem 77-Burglarproof
  • SlimLine 38 in all insulation variants


  • ConceptSystem 77
  • ConceptSystem 77-Burglarproof
  • ConceptSystem 77-Hidden Vent
  • SlimLine 38 in all insulation variants
  • MasterLine 8 in standard and High Insulation (HI) levels as four design variants

Sliding systems

  • MasterPatio

Curtain walls

  • ConceptWall 50-High Insulation
  • ElementFaçade 86

If you choose one of our C2C-certified systems, you build with circularity in mind. This sustainable label is both a sign of a durable mind-set and it shows the quality of the overall project. After all, the principles of the Cradle to Cradle certificate closely match BREEAM and LEED – both internationally recognised quality labels that determine the sustainability level of buildings. At Reynaers Aluminium, we are proud to offer products that match all these labels.

Reynaers Aluminium officers many BREEAM-certified products as well.
