Ice box insulation

[Fou Du Large]

Hello!

I'm looking to add insulation on the exterior of my (C-34 no-58 1986) ice box.
As i see, i can't see any insulation.

Is someone know how much insulation is in original boat from Catalina?

Thank you.

Fou : There wasn't much insulation around my 1988 fridge box.  There are a number of posts and tech note articles on how, what kind and where to add more insulation and keep the cold in.

We recently started bulking up the insulation around our icebox and found that the icebox walls are actually a sandwich of insulation between two layers of fiberglass. The insulation isn't very good; too thin in general (less than an inch) and full of large voids. We drilled holes from the inside of the icebox (through the first layer but not the second) and blew low-expansion foam insulation ("Great Stuff") into the voids. Where we hit a pocket of insulation we couldn't get any more foam in, but where we hit a void we put lots of foam in.

The next step is to insulate more around the outside of the sandwich, as has been described elsewhere on this website. We're planning to do it with more expanding foam; you can basically paint the outside of the icebox with it (at least where you can reach it). As for the starboard side, which is unreachable without cutting a hole in the hull, I think we'll drill more holes from the inside, all the way through the sandwich this time, and then repeat the foam trick.

Good luck,
Tim
