Sailing Dog... I have already determined what I need for insulation to achieve R-30 so it doesn't come into play in this question. The insulation will be added afterward. Your first question "How thick does the FRP have to be to support the loads?" comes closer to what I am asking.
Is 1/8" Fiberglass Reinforced Plastic sheets thick enough for a 4 cu. ft. icebox, if anyone has used this material before? Otherwise, how thick is the material you used in your icebox of about this same size?
An online marine refrigeration company suggested that this should be thick enough but I wanted others opinions...
