He used 1/2" foam insulation board from Home Depot. I noticeyou are in Belgium, so I don't know what stores you would have. You should be able to get it at a store that sells construction materials. Cork would probably work, but it would be much heavier and probably more expensive. He used 2 pieces of 4' X 8' foam board at about $13 each. Good luck and feel free to pm me if you have any questions.
