Selection guide

  • Acoustic comfort
  • Active fire protection

The advantages of the system

  • Installation: standard and cost-effective panel solution
  • Aesthetic: modular panels with various edge effects
  • Opening: very easy by simple lifting
  • Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)

Description


  • Wall-to-wall closed suspended ceiling composed of metal expanded panels laid on a conventional T-grid on all four sides
  • Steel or aluminum panels with different edge finishes compared to the grid: flat without edge (D0), straight edge (D1s), or recessed edge (D8-E15 and D8-E24)
  • Compatible only with T24 grid: D0, D1s, and D8-E24
  • Compatible with T15 grid: D8-E15 only
  • For a better finish in the panel module corners, prefer T-grids with Lay-On hooks without covering the flange on the transverse profile
  • Optional acoustic enhancements

Bulk cut

Dimensions in mm.

Appearance

  • Expanded mesh

    Dimensions

    • Mesh: Geometry WL x WD - LG x Th
    • Panel: width in the WL direction of the mesh, length in the WD direction
    • The recessed panels D8-E15 and D8-E24 are only compatible with the following meshes: KD100, KD200, KD300, RB15, and RB25

    Installation

    • The direction of light entry through the mesh depends on its laying direction, visually recognizable by its inclination.
    • Depending on the desired visual effect, the panels can be installed in the same direction or every other one can be reversed.

    *Aluminum is possible, please consult us.

    • From the ALPHA PLUS range, with specific bagged insulation

    Class A for all products from the ALPHA PLUS range, with specific surfaced insulation

  • Sound absorption

    According to the standard EN ISO 11 654

    • αw up to 1 (NRC = 1) with the ALPHA PLUS range

    Refer to the table in the Metal Acoustic Ceilings brochure.

    ALPHA PLUS offer: specific acoustic insulation surfaced with a veil or packaged in a PE film
    Refer to the Acoustic page in the Product Catalog appendices for more details.

  • Corrosion resistance

    Ceiling indoors

    • Class B according to standard EN 13964 for Steel frameworks
    • Comparable to Class A according to standard EN 13964 for Steel MESH panels (MESH not covered by this standard)
    • Comparable to Class C according to standard EN 13964 for aluminum MESH panels (MESH not covered by this standard)

    Suspensions and fixings to supports are to be selected according to the desired class
    Refer to the page Implementation in the Product Catalog's annexes for more details.

  • Cleanability

    By nature, our metal ceilings require minimal maintenance. However, various types of cleaning are possible. Refer to the Maintenance section of the Product Catalog appendix for more details.

  • Reservations, integrations

    Custom factory cutting on request.

  • Opening

    Access to the plenum by lifting the panel in the grid.

  • Resistance to disinfection chemicals

    Our metal ceilings are resistant to 2.5% sodium hypochlorite, 6% hydrogen peroxide, or 70% ethanol disinfectants (according to EN 12720 and ISO 11998 standards).

    Refer to the page Maintenance in the Product Catalog Annexes for more details.

  • Active fire protection

    According to standard EN 12845

    • If sprinklers are installed above the open cell suspended panel, the total open flat surface, including lighting fixtures, must not be less than 70% of the flat surface.
    • In practice, a percentage of void greater than 80% is commonly required for panel elements

    Ceiling void percentage

    • More than 70%: RB35, RB55, RB55 XL, RB75
    • More than 80%: RB55 XL
  • Reaction to fire
