Wrap this foam insulation around ducts and large diameter pipesit's moisture resistant and extremely flexible and soft. Insulation is made of closed-cell elastomeric Buna-N/PVC foam. Cut with a knife. Meets ASTM E84 25/50 for flame and smoke. Size is 36" x 48", unless noted.
Even the closed cell foam is only rated to 220* F.
Correct, we're not talking about an open flame.
Even the closed cell foam is only rated to 220* F. What if you used fiberglass, such as for duct insulation which is lined with alum. foil on one side - cut it to size, then spray it lightly with high-temp. (1200*) paint to hold the fiberglass in place, then totally wrap this in heavy duty aluminum foil and seal up with aluminum HVAC tape? Wouldn't that be able to handle higher temperatures? I'd think that the paint to stick down the fiberglass, plus totally encasing it in alum foil, would pretty much eliminate the chance of getting any fiberglass in your brew?
If (if) you get wort into the insulation, it is a big mess and has to be removed and thrown away. [ Been there. ]
lamarguy, did you get the adhesive backed stuff? If so, how well does the glue hold up?
How does the reflectix secure to the keggle
If you're seeking a higher R factor and higher temperature stability (220+), you may consider purchasing closed cell foam insulation. I believe Reflectix is only rated to 170F.
Good job on finding this product, I have ordered the 1/4 thickness and will wrap my pot with two layers. I have been thinking that I might put a layer of heavy duty foil between the two layers of foam. Does anybody have an opinion on this strategy?

I read on another post at HBT about the Keg Koozy as mash tun insulation. I got one for my eHerms mash tun setup and have had no complaints. Helps maintain the temperature and is easy to clean with a hose if you spill wort on it. I used a razor to cut holes for the sight glass, ball valve, and thermometer.

Anybody have any experience with pre-formed fiberglass pipe insulation? This outfit has some pre-sized for 16"dia pipe, 1" thick, rated to 1000degF, with a foil outer insulation. http://www.amerisafe.net/en/Fiberglass-Pipe-Insulation/FIBERGLASS-PIPE-INSULATION-12-X-12-KNAUF-ASJ-SSL-/10000_Group.aspx
I'm thinking of cutting it to the right length (top of the keggle), spooge the top of it with RTV like Bobby's approach, and it should take only minutes.
Trouble is, it comes in boxes of two for about $75+shipping. Anybody in the San Diego area interested in splitting?
