For cork over 15kg/m3 (1#) i do 4oz cork 2mm 4oz for bottom of wingboard and longboard surf it’s strong enough. For top on wing board 4oz cork 6oz biax carbon foot pad 4oz glass. Longboard: 4oz cork 9oz biax and for next better 5oz biax + 4oz warp.
On eps 20 and 25kg/m3 (1.25 and 1.5) i go fiber only bottom and sandwi h deck: 4oz cork and 4 to 9oz deck. Simple and cost effective build.
