Spline Panel - Army Museum

Efficiency and fascinating free-floating effects are hallmarks of Metalwërks® Arcwall wall systems.

Econowall floating metal panel - Product Image

With Arcwall, the cut edges of the faceplate material are the panels’ edges, a capability in metal you can only achieve with plate. When Arcwall attachment hardware is concealed from view, architects achieve a fascinating floating panel effect.

The fabrication efficiency of Arcwall, combined with Metalwërks simplified panel attachment options that speed installation, make for a highly competitive, high-end rainscreen wall system. Arcwall panels are factory assembled with a flat plate facing structurally adhered to an extruded aluminum panel frame and may be flat or curved. Two-dimensional geometries of panel facings are virtually limitless and panels may be installed in any direction. Joint sizes can be variable and reveals can use a complimentary or contrasting finish. There are three primary design methods.

All Arcwall systems install with concealed fasteners over continuous masonry, concrete, or as the outer cladding in a wall assembly that incorporates continuous insulation and a suitable air and water barrier. Solid metal panels are particularly useful where metal panels are used in pedestrian areas due to superior impact performance compared to other composite metal panel cladding products.

Arcwall Spline Details

Arcwall floating metal panel - Montgomery County Science Center
  • Manufactured from solid aluminum or stainless plate with extruded aluminum framing
  • Spline design method is achieved using a locking clip which can be engaged at any point along the panel. Panel joints receive a mating spline which conceals the anchor clips and allows for multidirectional panel installation.
  • High resistance to denting and puncturing, ideal for high-traffic or abusive areas
  • Mitered aluminum extrusion corners
  • 0.5” (12.7 mm) standard horizontal and vertical joint with variable options
  • Integrated knife plate reveals
  • Floating plate appearance with deep perimeter reveals
  • Adjustable furring to address variable construction tolerances and ensuring vertical sealing to air and water barrier, minimizing shims
  • Non-Combustible: minimal smoke or fuel contribution
  • Avoids NFPA 285 complications by using thermo-plastic cores
  • All panel systems are reinforced/stiffened to resist deflection limits
  • Multidirectional panel installation options
  • Concealed fastened using corrosion-resistant self-tapping screws into an engineered screw pocket with integrated drip edge
  • Aluminum: post-applied finishing for long-term performance and uniform aesthetic
  • As rainscreen systems rely on gravity to drain water, all skyward facing surfaces, copings, sloped conditions and all perimeters must be sealed
  • 100% recyclable with high percentage of post-consumer and industrial content, which may contribute to LEED credits
  • Seamless integration with other Metalwërks wall systems

Arcwall Spline Design Options

Arcwall floating metal panel- Columbus AP
  • Panels may be flat or curved
  • Variable reveals: Horizontal 0.25"-4" (6.35 mm-101.6 mm) and Vertical 0.25"-6" (6.35 mm-152.4 mm).
    Consult with Metalwërks for Arcwall joint options.
  • Available with appliqués or perforated face skins
  • Virtually unlimited color options for aluminum plate
  • Options for #4, #6, #8, and non-directional finishes for stainless steel plate
  • Matching perforated and louvered panels
  • Projecting eyebrows with integrated framing can be included
  • Enclosures for exposed columns, beams or pilaster features can be clad using materials and joint treatments to achieve matching aesthetics
  • Ideal for flat, curved, sloped or vertical walls and soffits where the design intent is for pronounced reveals between the panel units and extremely sharp panel edges.
