H8-E15

Acoustic absorption

• αw up to 0.80 (NRC = 0.80) with the ALPHA range
• αw up to 1 (NRC = 1.00) with the ALPHA PLUS range

Discover our video "Acoustic Metal Ceilings" in the Documentation/Videos section.

Acoustic filling

• ALPHA offer: as standard, a black veil PLAFOMETAL is thermally bonded on the back of perforated ceilings.
• ALPHA PLUS offer: a specific encapsulated insulant to be applied on the back of perforated ceilings.

The acoustic performances of the ceiling systems are guaranteed for defined, controlled, and fully delivered products by PLAFOMETAL.

Light Reflexion

• Up to 87%.

Fire reaction

According to the EN 13501-1 standard:

• 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 post-coated products
• Euroclass A2-s1, d0 for powder-coated post-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 recommend specific 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 on other ceilings
• Ethanol 70%: only white pre-lacquered, black post-lacquered, and wood finish ceilings show minor visual changes, no visual changes on other ceilings

This also applies to 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

• Grid installation

Implementation

• Implementation according to DTU 58.1
• Grid installation: hangers every 1200 mm with wall starting point at 300 mm and carriers every 1200 mm.

Disassembling for access to the plenum

• By simply lifting the panel within the grid.
• Access door available, please contact us.
• Potential anti-lifting of the panel by adding CA113 brackets at the perimeter.
