I am almost done!! In the plans the keg box is lined with thin alumnium sheet. What are these are where can they be purchased?
jpm,
Most hardware stores carry very thin aluminum sheeting in small sizes like 24″x36″ or 24″x48″. The stuff I found was in a Menard’s store (midwest US), but you would probably be able to find similar material in a Home Depot or Lowes. Ask the “floor walkers” for assistance…
I don’t recall the exact thickness, but it’s about twice that of a (vintage) beer can…probably .01″ thick and is easily cut with an aviation snips or metal scissors. (modern beer cans are probably .001 thick).
If you have a nearby metal scrap yard, as them if they have any old Litho Plates from a printing company. These work well too, just be sure the printed side is “out”. Some yards stopping selling these since some of the graphics on the old plates could be copyrighted material. I used sheets like this for the siding of an Ice Fishing shack I built a few years back and when I told them what the use was, they sold me the sheets (only in Wisconsin eh?)
I used the aluminum primarily on the floor, to allow the keg to slide easily and on the inside of the door panel and around the inner door frame.
When you place the sheeting on the floor, first cut it and test fit, then apply a layer of foam (great stuff) between the wood and the aluminum. This creeats a thin thermal barrier and also acts as a good adhesive.
For the keg box door, be sure the majority of the door’s core is filled with styrofoam, but before putting the strofroam in place, use foam again so there is a layer between all wood surfaces and the styrofoam which should fill any air spaces.
The whole idea is to fill every single possible air space with foam. The aluminum sheeting is a great thermal conductor, but that layer of foam stops the cold from penetrating the door and the floor.
The wall of my keg box are just 1.5″ thick Owens Corning Pro Pink (R factor of 7.5) and I doubled that up when ever possible. Between the layers of Pro Pink, guess what I used…yup!, another layer of Great stuff foam!
If you have any other questions, fire away!
