PM2 Hooks

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

Acoustic filling

• ALPHA Offer: as standard, a black veil from PLAFOMETAL is thermally bonded to the back of perforated ceilings.
• ALPHA PLUS Offer: two filling options are available. The specific surface-treated insulation for optimal performance or the specific bagged insulation to avoid fibers.

The acoustic performance of ceiling systems is guaranteed for defined, controlled, and fully delivered products 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 recommend certain disinfectants more particularly 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 precoated, 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 precoated/post-lacquered steel or aluminum products in 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
• Gridding installation: hanger spacing 1200 mm with wall start at 300 mm and band-spacing up to the self-supporting panel.

Disassembling for access to the plenum

• By lifting the panel in the grid.
