PLAFOMETAL-EM-240

MESH ceiling hooked on concealed carrier with D91s and D91t panels

Ideal for :

Entrance halls and wide corridors

PLAFOMETAL-EM-240 is a system with a modern aesthetic appearance. The D91s and D91t expanded metal panels are self-supporting, hooked between concealed carriers, and are suitable for wide corridors where the self-supporting feature of the EM-110 system is not sufficient. Their robustness combined with a wide opening will facilitate maintenance phases throughout the life of the building.

Selection guide

Active fire protection

The advantages of the system

Aesthetic: panels with a modern look featuring hollow joints between panels and the wall.
Dimension: selection of various panel widths and lengths.
Opening: demountable with wide plenum access.
Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1).

Description

Wall to wall suspended ceiling composed of expanded metal panels hung on carriers forming a concealed joint
Self-supporting steel panels
The panels are equipped with an interior hook-end (BRIC) at one end for suspension on the grid and at the other end with a Z-shaped hook-end (BRZ) resting on the end of the adjacent panel
The carriers are made of steel
Optional acoustic enhancements

Bulk cut

Appearance

Expanded mesh
Dimensions
- Mesh: Geometry WL x WD - L 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 laying direction, visually recognizable by its inclination
- Depending on the desired visual effect, panels can be installed in the same direction or alternated every two panels

Performance

Indoor air quality
Class A+ for all products:
- Unfilled
- 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 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.
Acoustic complement
ALPHA PLUS offer: specific acoustic insulation surfaced with a veil or bagged in a PE film
Refer to the Acoustics 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 cleaning methods are possible. Please refer to the Maintenance section in the Product Catalog Appendices for more details.
Reservations, integrations
Customized factory cutting on request.
Opening
Access to the plenum by vertical push 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 sodium hypochlorite 2.5%, hydrogen peroxide 6%, or ethanol 70% disinfectants (according to EN 12720 and ISO 11998 standards).

Refer to the Maintenance page 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 light fixtures, must not be less than 70% of the flat 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
