gman,,good to see you post again! i would recommend 3-4" of closed cell in the 1.7-2lb range.... the open cell would work if you could get enough depth for an R-25 minimum...just dont forget the vapor barrier on the WARM side of the wall,,, you will notice most prefab panels are ~5" polystyrene with the aluminum skins... re: soyfoam: foam is foam if processed correctly...polyol is polyol whether soy, canes, petro or PET,,,, have a great weekend!! |

We just did a cooler for a customer of ours, and we did 3-4" of 2lb closed cell foam. By using this type of foam the customer didn't have to worry about having to add a moisture barrier to the unit. I wouldn't recommend using an open cell foam due to the amount of water that is known to appear inside of coolers. The one that we sprayed will mostly hold case's and kegs of beer, so moisture will be around. We will have some photo's of the cooler posted in our photo gallery later today if you would like to take a look. |

coolers are typically fairly "dry" due to the dehumidification process that accompanies the cooling process... heat flows from hot to cold... inadequate insulation and a leaking structure will cause condensation when the warmer outside air infiltrates,, flowing to meet the colder inside air,, a closed cell foam would be my recomendation,,again.. but open cell will work fine if a vapor barrier/retarder is used on the warm side of the wall and if there is adequate Rvalue to reduce the transfer of hot to cold... |
