The raw mineral wool touches the keg. The side that touches the flashing received a coating of 3M super 88 and so did the flashing. If you don't plan to take it apart much ( haven't yet), then adhesive is not necessary. The key is to keep wort and water out of the mineral wool.

Brilliant Bobby! I'm going all electric but I'm still planning on doing the "Bobby_M Insulation" to all my vessels as I think it looks a lot better than what I presently have (aluminum bubble wrap). Thanks for the idea.

thanks so much for the clarification. I look forward to receiving the sightglasses I ordered from you today = no more measuring with a stick, etc.

cheers

Anyone have any experience with the mineral wool with the wire mesh backing on it? I know it's 3x the cost, but I was thinking about using that and just fastening it to the keg using ratchet straps or bunjee cords. Do you all think that the mesh will give it enough structural support to keep it from breaking apart?

I doubt it. The wool wants to disintegrate into tiny pieces if you look at it the wrong way.

Hey I found this site if anyone wants to check it out. Some custom cut sheeting for like 5 dollars more that flashing.

Bobby,

Over a year later how is your setup holding up?

I just stumbled across this thread. I am interested in giving this a try.

I tried the reflectix and aluminum tape a year ago, and ran into melting issues when heating my strike water. Not only that but the fumes that came off the solvents in the tape were horrible! Never again! I have considered rigging up reflectix with velcro and not tape this time but this post looks promising.

Bobby, how stinky has this new setup been? Silicone is stinky when first applied but usually fades, but I have never heated it before. How about that 3M adhesive and mineral wool? Has the seal maintained overtime?

thanks!
Mike

It's holding up like a beast. Honestly the most wear and tear it has seen so far is the random interested party poking at the silicone seal at the top to try to figure out what it is. My previous solution was doubled reflectix with velcro but even thought it was easy to remove didn't mean I'd remember to remove it when the flame was lit.

I have not removed the insulation or metal wrap since it was installed as I've always just cleaned in place. It doesn't appear that the silicone seal has been compromised at all and I don't think the wool has gotten wet. The silicone smelled solventy when it was first applied but it was gone within a week. I don't notice any smells at all during heating. The very bottom layer of wool is exposed to the heat but it doesn't flinch or smolder.

I could probably start my own thread, but Bobby maybe you can answer this. I've got an E-HERMS and want to insulate my mash tun. My three options are:

1. Your aluminum armored insulation
2. Reflectix
3. the adhesive backed foam insulation from McMaster

What would you recommend as my best option? The vessel is a keggle.
