Check out our video "Acoustic metal ceilings" in our Learning Center.
- ALPHA offer: black acoustic fleece bonded on the back of perforated ceilings.
- ALPHA PLUS offer: two options of acoustic inlays are possible. The surfaced insulating wool for optimal performances or encapsulated insulating wool to avoid fibers.
Acoustic performances of ceilings are guaranteed for products defined, controled and entirely delivered by Plafometal.
- Up to 87%.
According to EN 13501-1 :
- Euroclass A1 for the prepainted non-perforated
- Euroclass A1 for the prepainted in the ALPHA range
- Euroclass A2-s1, d0 for non-perforated powder post-painted
- Euroclass A2-s1, d0 for powder post-painted in the ALPHA range
- Euroclass A2-s1, d0 for the product in the ALPHA PLUS range
Our metal ceilings and wall panels have been tested with three types of disinfection chemicals recommended by the World Health Organization against the main viruses, including COVID-19: sodium hypochlorite 2.5%, hydrogen peroxide 6% and ethanol 70%.
Test methods include long or repeated exposures to these chemicals. The results are evaluated according to the standard exposition EN 12720 and the standard disinfection and wet abrasion ISO 11998 (tests carried out with a microfibre cloth).
All metal ceilings are resistant to these three disinfectants. However we recommend some product depending on the use:
- Sodium hypochlorite 2,5%: OK for all ceilings (no visual change)
- Hydrogen peroxide 6%: only black powder-coated ceilings show minor visual change ; no visual change on other ceilings
- Ethanol 70%: only white prepainted and wood finish ceilings show minor visual change ; no visual change on other ceilings
This is valid for all products (steel and aluminum, prepainted and powder coated, with acoustic complement).
Environment and health
- Our ceilings can be fully recycled over an indefinite period of time.
- They are sustainable, easy to maintain, produce no dust, particles or vapor, are inert and odor-free.
- They do not promote microbial growth and do not emit any VOCs or formaldehyde.
- DoP No.: 0007-200.
Indoor Air Quality
The products are classified:
- A+ for all the products non-perforated
- A+ for all the products in the ALPHA range
- A+ for all the products in the ALPHA PLUS range, with a specific mineral wool pad in this plastic film
- A for all the products in the ALPHA PLUS range, with a specific mineral wool pad with black tissue face
