Primary Decking Materials

IMO/MED Certified deck covering Mobility

Green shipbuilding reaches cruise speed with the help of Amorim Cork Composites’ primary decking materials. Innovative and sustainable cork-based interior primary deck solutions which ensure that ships comply with safety standards while significantly reducing their carbon footprint.

The key factor in ensuring a negative carbon footprint is the cork oak forest itself - which is a carbon sink, responsible for retaining 73 tons of CO2 per ton of cork used for a typical application, which corresponds to 2,7 kilotons of CO2 retention.


Exterior Primary Decking

ACM30 is a cork composite, a material specially formulated to be used as an exterior primary deck covering for levelling and fairing with additional features with IMO/MED certification. 

Due to the materials composition it significantly benefits weight reduction, being 2 to 5 times lighter than available primary decking solutions therefore improving vessel performance and rating, and consequently delivering energy savings. It also serves as a structural damping, soundproofing and thermal insulation barrier of the deck.
