Lightweight aluminium curtain wall facades with Metawall®

The product variation of Metawell® especially for facade cladding is called Metawall®. Because of the ingeniously simple design, a very light and extremely rigid aluminium sandwich panel is created, which is perfectly suitable for curtain wall facades.

The continuous production process allows the fabrication of unusually large facade elements with a flat surface. The element remains dimensionally stable and plane, so a larger effective span can be realised with less substructure. Since the sandwich core is also protected against corrosion, the material has a high resistance to corrosion and is 100 % recyclable without previous material separation.

Different colors, e.g. RAL, NCS, BS, Pantone and metallic colors, can be offered. Individual color schemes are available on request. Unlike other sandwich panels, Metawell® panels can be powder-coated on request – so individual coloring for smaller quantities is also possible.


  • Aluminium sandwich panels with corrugated core for large facade elements
  • Weight savings due to lightweight construction
  • Fire classification acc. EN 13501-1: B - s2, d0 or A2 - s1, d0, NFPA 285 and ASTM E84 (passed)
  • Building inspectorate approval: Z-10.3-708 (DIBt Germany)
  • Economical, due to larger spans and less substructure for big facade elements
  • Various colours available (custom designs, decors, gloss, metallic colours and colours according to RAL, NCS, BS and Pantone)
  • Sustainable, thanks to raw material savings and full recyclability (without previous material separation)
  • Excellent corrosion protection (also of the core)
  • Environmental Product Declarations acc. DIN EN ISO 14025 Type III and EN 15804
  • BIM-objects for ArchiCAD and Revit

Depending on the requirements of static and fire classification, there are two different aluminium facade products:

Rear-ventilated facades with Metawall® A2

With properties similar to Metawall® B1 the aluminium sandwich panel Metawall® A2 offers with a panel thickness of 15 mm a fire classification of A2.

  • Overall thickness: 15 mm
  • Weight: only 6.8 kg/m2
  • Non visible fixing method: riveting
  • Perfect flatness also for big elements (max. 1460 x 6000 mm)
  • Building inspectorate approval: Z-10.3-708 (DIBt Germany)
  • Fire classification acc. to EN 13501-1: A2 – s1, d0 (non combustible), NFPA 285 and ASTM E84 (passed)

Curtain wall facades with Metawall® B1

With the low weight of 5.2 kg/m2 Metawall® B1 is extremely stable and convinces with a panel thickness of 10 mm in terms of energy-efficiency and sustainability by saving raw material and is completely recyclable.

  • Overall thickness: 10 mm
  • Weight: only 5.2 kg/m2
  • Non visible fixing methods: glueing (up to 4300 mm) and riveting
  • Perfect flatness also for big elements (max. 1470 x 6000 mm)
  • Building inspectorate approval: Z-10.3-708 (DIBt Germany)
  • Fire classification acc. to EN 13501-1: B – s2, d0 (flame retardant)

Rear-ventilated facades

Rear-ventilated facades can be realized with Metawall® aluminium sandwich panels. Find out more about the construction of rear-ventilated facades, the advantages and disadvantages and why Metawall® aluminium sandwich panels are particularly suitable for implementation.

Products of Metawell GmbH are technically unsuitable for the following applications:
– wall and roof elements which require an integrated thermal insulation – PU foam core
– roof elements as supporting components
– balcony and parapet fall protections
