Acoustic filling
- ALPHA Offer: as standard, a black PLAFOMETAL veil is thermally bonded to the back of perforated ceilings.
- ALPHA PLUS Offer: two filling options are available. Specific surface-insulated for optimal performance or specific bagged insulation to avoid fibers.
The acoustic performance of ceiling systems is guaranteed for defined products, controlled, and fully delivered by PLAFOMETAL.
Light Reflexion
- Up to 87%.
Fire reaction
According to standard EN 13501-1 :
- Euroclass A1 for non-perforated pre-coated products
- Euroclass A1 for pre-coated products from the ALPHA range
- Euroclass A2-s1, d0 for non-perforated powder coated products
- Euroclass A2-s1, d0 for powder coated products from the ALPHA range
- Euroclass A2-s1, d0 for products from the ALPHA PLUS range
Chemical resistance
Metal ceilings are resistant* to sodium hypochlorite 2.5%, hydrogen peroxide 6%, or ethanol 70% disinfectants. However, we particularly recommend certain disinfectants based 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 also applies to all pre-lacquered/post-lacquered steel or aluminum products from the ALPHA, ALPHA PLUS, and DECIBEL offerings.*exposure according to EN 12720; disinfection and wet abrasion according to ISO 11998
