I pulled the floor in the v-berth and the sandwich material looks like 3/8 balsa. I'm still debating pulling the cabin floor. The post I 've suggest that this is sandwich with vermiculite.
1. Is vemiculite distincntly different than balsa?
2. Since the v-berth area is small, I could use the rest of the balsa sheet(2x4) for the cabin. Rather than order two different materials, is there and problem with using balsa in the cabin floor?
thanks
