Since my boat is on the hard, I decided to add to the insullation in my freezer/frig on the 36T. I have had 2 layers of the 1 inch foam insullation with the "aluminum" backing and can keep ice for about a week in a compartmentalized freezer that spills over to the frig. What have others used to add to the basic CS insullation?
I purchased a roll of "bubble" astro-foil from home depot that claims R values of from 15 (down) to 7 ( horizontal) to 5.4 (up) and plan to add this layer to the other 2 of the foam panels. Any experience that can add to my project?

Terry,
I'm assuming that this is an icebox and not a powered fridge? I know Nova Kool recommends 3-4" of foam insulation on their webite for the most efficient operation. If they ae talking about the rigid blue of pink stiff, this represents an R20.
I assume that for an iceox setup, this would be the ultimate number you'll want to achieve as well. Assumint the foam you have is the rigid extruded stuff, you've already got an R10. I dont know the R value of the white foam per inch. Two wraps of that bubble stuff and ou should have quite the cozy icebox.

Dan:
It is a powered ice box and the foam is the rigid pink stuff...two layers. I am almost happy with it but would still like to cut down the hours needed to keep it cold, especially down here in Texas' summers. I have to raise the holding plate a couple of inches so I can add the bubble stuff underneath the plate.

Terry,
Another question since you are in a hotter climate is how is our condenser cooled, air or water? If you have the water option, they recommend that in hotter climates. This will also improve he efficiency of the unit.

Dan:
I have both water and air, but have found the water option to be less than useless...the pump eats amps as you know and I can see no improvement in cooling. In addtion, I was cruising a site and the moderator was sort of a fridg guru and he said not to use the water option especially in salt water since it corrodes the pipes quickly. I flushed out the unit and disconnected the pump from the fridg and only use it to prime the A/C when it looses its prime.
