RE: I cannot see that polyU will outperform Styrofoam in compressive or tensile strength - maybe the shear capability is the issue?
I question strength being an issue at all, when deciding on what foam to use I thought that is was just there to be shaped and covered with glass. Is this a wrong conclusion?
