NSP/ Southpoint Snap

Today I recieved a snapped NSP/Southpoint longboard to repair.Does anyone know anything about the thermoformed polymer (PVT) skins? The ad on their website says they are glassed with multiple layers and densities of fibreglass fabric.The only glass that I can see on the board I have is Chopped Strand Matt.Any info would be appreciated.Seems like a waste of time glassing and then thermoforming a board if you are going to use CSM. Even more so if you are using epoxy.David.
