I don't know if all Hanse 342s look the same but this is how it looks on mine. (The outside of the cooling box looks wet because I sprayed it with water to prepare for foam to be sprayed.)



The way I made sure I could spray foam into a confined space was to put pieces of extruded polystyren in the opening. It looks like this:

I don't. That's why I practised with the foam in my garden so I would get a good idea of how it will react when I do it in the real situation.

The task to insulate the fridge is now in its final stages.

I have sprayed foam around the box on all sides. There has however not been possible to spray under the box, which is the most important place as cold wanders downwards.

I have solved this by cutting a 50 mm thick piece of extruded polystyrene to put at the bottom of the box, from the inside. I was considering putting two layers but thought 100 mm less from the bottom of the box would make the box too small.

I have finished the job by putting a piece of aluminium at the bottom of the box and on the sides to cover the holes that I made to spray foam. Now I only have to do some polishing and put the lid back. I will also try to find a new spring for the lid as the old one seems have lost some of its former tension.
