Icebox re-insulating

[Harman]

I am rebuilding my icebox on my Cal 28.The icebox I have in there doesn't seem to have enough insulation (the top is just a wooden board on hinges).Does anyone have any advice to to this?Should I use the old liner or should I make or get a new one made?Any insight would be greatly appreciated.

Doing the same.

Like yours my top is just the counter and formica. And it has two 3/4" wood "doors" on top, one in the galley and one in the lazarette. My plan is to glue 1" thick insulation to the inside of the top and permanently close off the lazarette opening. I could use thicker insulation but do not want to give up the space. For the same reason I am not doing the sides nor bottom.In my boat there is no way to do anything on the outsides of the box. The only other option would be to rip open the galley and install a new box with six-inch thick walls. Might do that someday when time permits.

Be sure to seal the lid.

Adding some insulation on the top is fine. As we know, cold air sinks so it is really best if you can find a way to do more in the lower part of the chest. All insulation helps. Another thing (if you have access) is to place any type of insulation to the areas that may intrude into a lazarette. You can sometimes just glue sheets of foam on the outside of the existing box.I found that using some of the 'P' type weather stripping that they use on doors and windows around the lid help a lot. We have a Technautic refrigeration system and before we added this to the lid there was a large build up of ice on the holding plate. Now there is very little ice build up.
