. It might be more in corners but rough estimation about 6 layers of 300 g/m2 is at least enough (thickness about 2mm) twill glass fiber. you can also make one pillar so that you take out the foam from inside and see what is the effect to rigidy.

It's enough with one layer of glass on each side, when foam is still in the middle. Extra laysers of glass cloth in corners, stress points ect. 6 layers will add too much wheight, and is not needed when the foam is encapsuled with glass and resin on boths sides.
