Chemical resistance

Our metal ceilings are resistant to sodium hypochlorite 2.5%, hydrogen peroxide 6% or ethanol 70% disinfectants (according to standards EN 12720 and ISO 11998). Please refer to the Maintenance page of the appendices for more details.

Type of installation

• Installation in circulation areas
• Grid installation

Implementation

• Installation in circulation: fixing range to be attached to the wall every 300 mm and hanging profile to be assembled with self-drilling screws under the fixing range every 300 mm. Maintain a minimum space of 15 mm between the wall and the edge of the panel.
• Grid installation: hanger spacing 1200 mm with start of the wall at 300 mm and carrier spacing equal to the panel length (up to its self-supporting capability) +3 mm. The edge finish can be created with the profiles and the hollow joint used during installation in circulation under the condition that the panel length is compatible (full panels on the edge) with the room dimension. The hollow joints, whether butt joints or edge-to-edge, should be balanced during installation to ensure visual consistency (use of shims recommended).

Disassembling for access to the plenum

Disassembly of the panel by vertical push then lateral translation to escape the hook-on profile (and the neighboring panel in the case of a tramway installation). Clearing from underneath by tilting it on one side. Reinstallation in reverse order while respecting the alignment of one element with the other.
