Ice box gasketing

[scgunner]

     It was a stock install on the C34, but like many things on the boat it can always be upgraded.

Does everyone have the 2" or so, thick,  insulated fiberglass panel screwed to the underside of the lid?  I assumed it was factory installed in my '86.  Or do some people have just the plywood lid?  I always assumed I was getting some leakage around the opening lip but never thought it was too bad.
I also installed some 2" rigid styrofoam pieces on the underside of the countertop between the refer opening and the edge of the icebox.

I do have the same inner piece.
