We have a lot of bears here so I sure hope they don't get out there. I used 2 pieces of 2" Foamular glued and screwed to a piece of 1/2" PT plywood.

I am going to improve it by adding a third piece of Foamular and another piece of plywood and bolting it all together in a big sandwich. That will be better than this one. I was in a hurry to get the feeder operational and I thought of the improvement as I was building it. Unfortunately my pond is not any where near a building supply store.

BTW. Foamular is rigid styrafoam insulation. It is very lightweight and denser than plain styrafoam.
