what to put on the insulation in icebox

[sailsail]

Our Allmand is 30 years old......the insulation that might have been in there has long since died. There is no way to get to the outside of the box. Yesterday we covered the inside of the icebox with pink hard foamboard insulation (Corning foamular 250). What should we put on top of that to protect it from 'dings' and scrapes, etc? The only thing I can think of is thin bubble wrap. Any other ideas? Anything we could spray on?

Also, will there be a problem with dampness and mold/mildew getting behind the boards? We did not glue the panels in place ....we used velcro tabs so we can remove them if necessary.

Me, I would paint the original IB walls with a TBT mold inhibitor additive to the paint of your choice. Then wrap your insulation with the heaviest aluminum foil available or alu duct tape.But, then I always had to it on the cheap. Also, if you can get any insul outside the engine side, do it. I think you figured it out pretty well, with the givens at hand.

What about something like linoleum or place and press tile? Cheap and waterproof

When I made ours I lined the...

... inside with Wall Board. It has a pebble finish on one side and smooth on the other. I got it from the local lumber yard at home, but Home Depot...

... and others have it in 4 X 8 sheets. I did not glue it to the sides of the foam. If you do make sure you use an adhesive that won't melt the foam or the Wall Board. I held it in with ...

...the trim that is made for the board and since I wasn't sure if I would have to modify something when we got to the boat I also used the duct tape. Since it fit the boat fine I went ahead and caulk the bottom and trim and will do the same to the sides and top when we quit using it this trip and pull the duct tape off.

I can't give you a long term use results, but so far I like it. Here are a couple more pictures.

The above shot is how the galley looked after pulling out the 12/110 volt upright frig (arrow).

This is how it looks after working on it this trip.

The frig is all one unit, about 4 cu. ft. (including the freezer section). It extends about 17+ inches further out than the old one. There are two openings into the top of it (bottom left arrows). One is under the cutting board top, bottom left lower arrow and the other is a new cutout in the old counter top, bottom left upper arrow. The first picture in this post is down into the outer area where we keep things we want to get to more often. The second picture in this post is down into the other opening where the freezer section is also located. It has worked great. The top and lids are 3 inches thick, the sides 4-6 inches and the back and bottoms are 6-8 inches thick.

I also made a large storage area above the frig, top left arrow and a storage area for plates and silverware (in the sugar dispensers) top right arrow.

Good luck with the frig and the insulation will pay off,

Sum

How does that foam board clean up? Wouldn't lining the outside be just as effective? I'm not sure what is on the outside of the ice box on the C-27 since it is enclosed. Does any one know?
I finally got around to cleaning it yesterday. What a mess. The PO rerouted the drain hose to the top of the sink drain hose. I disconnedted it and like a sewer trap the water was black and rancid. Yuck.

I covered mine with very light weight woven fiberglass cloth held in place with 3M spray adhesive and coated with epoxy paint. It had to be that way because my ice box is not completely straight sided one side follows the cure of the hull. After 12 years of servce it has held up very well and has not needed any repairs

 

[sailsail]

Ross, did you put the fiberglass cloth on top of insulation? And I assume the 3M spray adhesive is compatible with the insulation board?
Our box is the same as yours.....ie, follows the curve of the hull on the one side.

I used canned foam to fill all of the joints and smoothed them with knife and very coarse sand paper. The solvent in the spray adhesive is turpentine and the styrene foam is fine with that . I allowed of plenty of overlap at the corners sniped the wrinkles with scissors. did one surface at a time but did them all in one go. I let them dry and the solvent evaporate overnight and then painted the next day . The foam is immune to west system epoxy. I used fiberglass window curtains but I doubt that you can find them any longer. You could use polyester sail cloth just as well. Try some on some scrap and see if you like it. Just an old junk sail would serve.

Ingenuity at work. A host of good ideas.

 

[sailsail]

yes, lots of good ideas. Thanks.

Did anyone ever have problems with mold/mildew accumulating on or under the insulating board?

 

[tigerregis]

sailsaill, yes I did. That's why my TBT reference. I left the foam open. NG. Mold did show up. Sprayed regularly with bleach solution. Good news is everything worked as best it could under the conditions. Great Lakes to Green Cove Springs and back. Summers in Annapolis with its heat and humidity. Early 80's boat with no provision for long term cruising.
