Chemical resistance

Metal ceilings are resistant to sodium hypochlorite 2.5%, hydrogen peroxide 6%, or ethanol 70% disinfectants. However, we particularly recommend certain disinfectants depending on the type of ceiling:

• Sodium hypochlorite 2.5%: no visual changes on all ceilings
• Hydrogen peroxide 6%: only black post-lacquered ceilings show minor visual changes, no visual changes are observed on other ceilings
• Ethanol 70%: only white pre-lacquered, black post-lacquered, and wood finish ceilings show minor visual changes, no visual changes are observed on other ceilings

This is also valid for all pre-lacquered/post-lacquered steel or aluminum products from the ALPHA, ALPHA PLUS, and DECIBEL ranges.*exposure according to EN 12720; disinfection and wet abrasion according to ISO 11998

Type of installation

• Framed installation

Implementation

• Installation according to DTU 58.1
• Grid installation: hanger every 1200 mm with wall starting at 300 mm and grid spacing up to the self-supporting of the panel.

Disassembling for access to the plenum

• By raising one edge of the panel (covering side) in the grid.
