Selection guide

  • Acoustic comfort
  • Active fire protection

The advantages of the system

  • Aesthetic: panels with a pronounced appearance due to wide hollow joints
  • Dimension: choice of different panel widths and lengths
  • Access: easily removable from below with wide access to the plenum
  • Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)

Description


  • Wall to wall suspended ceiling made of expanded metal panels suspended on carriers forming a large concealed joint
  • Self-supporting steel panels
  • The panels are equipped with an interior hook-up at their ends allowing them to be suspended on the structure
  • The carriers are made of steel
  • Optional acoustic additions

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

    Installation

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

Performance

  • Indoor air quality

    Class A+ for all products:

    • Unfilled
    • From the ALPHA PLUS range, with specific encapsulated insulation

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

  • Sound absorption

    According to standard EN ISO 11 654

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

    Refer to the table in the Acoustic Metal Ceilings brochure.

  • Acoustic complement

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

  • Corrosion resistance

    Ceiling indoors

    • Class B for standard steel frameworks according to standard EN 13964
    • Corrosion resistance C1 according to EN 12944 for standard steel MESH panels (not covered by EN 13964)
    • Corrosion resistance 2a according to EN 13096 for aluminum MESH panels (not covered by EN 13964)
    • Suspensions and fixings to supports must be selected according to the intended class
    • Refer to the Implementation page of the Product Catalog Annexes for more details.

  • Cleanability

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

  • Reservations, integrations

    Customized factory cutting on demand.

  • Opening

    Access to the plenum by vertical push and then lateral translation to escape the hanging carrier. Clearance from below by tilting it to one side.

  • 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 Maintenance page in the Product Catalog annex for more details.

  • Active fire protection

    According to standard EN 12845

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

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

Ideal for tertiary buildings, hospitals, airports, parking areas...

Aesthetics:

  • Wide range of meshes for different optical effects with natural or artificial light coming from the plenum
  • Depending on the installation direction and observation angle, the metal appears more or less open
  • Ideal solution for elegantly delimiting technical areas
  • Various finishes with shadow joints depending on the systems

Acoustic:- Possibility of absorption αw up to 1.00 (NRC = 1.00)Practical:

  • Easy installation and opening
  • Robustness during handling
  • Allows active fire protection networks to operate through the ceiling

Sub-family : Plafond MESH suspendu
