Replacing the separating wall between the freezer and fridge

Hi all

The separating wall between the freezer and the fridge on my 1999 H410 is made of synthetic resin coated wood. We all know, that the bottom of the fridge get soaked, especially when thawing after usage. The box itself is made of GRP. The top of the wall also serves as the supporting surface for the two top covers. The sealing lids are pressing against this surface to get the boxes airtight. In the freezer, the cooling plate is bolted on this wall. It has also an opening, in which a small fan is installed, to push cold air from the freezer in to the fridge (the fridge has no cooling plate on its own). There are two more openings in this wall, one for letting the air circulating between the two boxes and one at the bottom, to drain the freezer, as the entire box has only one drain in the fridge for the whole box. Finally, the wall supports the two air cylinders, helping to keep the top covers in an open position. The overall wall thickness is 2 inches.

Now I like to replace this wall. The rotting wood is not what I want in the place where I store my food.

Has anyone already done this project? What material wood you recommend? Any pictures around?

My plan is, to build a frame of square profiles from polyamide PA6, then filling the space with extruded polystyrene. The insulation and profiles will then be covered with a plastic foil to avoid condensation in between the layers. After all, the outside is made of polyamide PA6 sheets. I would screw the whole thing with stainless steel countersunk screws.

Any suggestions / ideas? All much appreciated!

Take a look at King Starboard which is HDPE. http://www.kingplastic.com/products/king-starboard/ No rot. Moderate structural strength. Impossible to glue so use mechanical fasteners only.
Thank you Ralph.
Why would you prefer the Starboard over the Polyamide? I need to seal the separator against the box and thus trying to find a material which is at least somewhat tolerant for a grout material.

Marco, the design sounds similar to mine but I appear to have a foam insulation in the wall, at least where the spill over fan hole was cut.
Would it be possible to remove the skin on the refrigerator side of the wall using a Fein type saw ? Then repair and insulate the inside of the wall and then just replace the skin and seal the seam ?

Re: Replacing the separating wall between the freezer and fr

Hi Bob,
would be an easier fix compared to replacing the whole wall. But the wood is really rotten and I expect the cover would not come off easily. So I think by the end of the day, creating a whole new wall is less painful - hopefully! The advantage of replacing the whole thing is, that I can prepare everything here at home, and then just adding the ventilator, the blocks for the gas cylinder and such.
