Was that measured? I don't see any insulation values in the catalog.
TIA.

Yes, with K thermocouples between tank and insulation and under tie
wraps and with IR before and after.

What am I missing here? I would put the TC on the OUTSIDE of the insulation to
measure the temperature drop. For what its worth, the external temperature of
the boiler would RAISE with the addition of insulation, all things being equal.

Uh, "under tie wraps" is on the _OUTSIDE_ of the insulation.
http://www.ielogical.com/coffee/BoilerInsul.JPG shows the tie wraps on
the _OUTSIDE_ of the boiler. ;-)
To be perfectly clear :
TC 1 between boiler and boiler side of insulation
TC 2 between insulation and tie wrap on air side of insulation on
rear, non group, side of boiler.

Probably so, but I set boiler temp lower with PID than with pStat.
IR measurements made on side of boiler _AWAY_ from thermosyphon.
Thermosyphon side of outside of insulation gets warmer [scientific
term] than opposite side due to heat radiated by thermosyphon and
reflected from rear of front [where the group [where the coffee water
comes out] is mounted] panel of machine. WHEW!!! ;-)
Note : Measurements made with shell of machine removed. There is
likely to be some variation in temperature difference due to 'cover
effects.' I'm planning a white paper with Dave, Robert, Ken and Jim on
the effects on shots of 'cover effects'... ~<:-P

Yee gawds! 136 bucks for a 24" by 24" piece?! I don't think so.

I wonder if your basic sillycone rubber counter protector would work?
They are safe up to almost 500F and are food grade. Although they
are thin. I use a silicone oven mit for moving the wood box in my
smoker and it's upwards of 240F.

Didn't evaluate these, but we have some siliicone cooking sheets and
they are solid, with no bubbles, so not sure how well they would
insulate.

I'm looking to break even in 2020.
It's the only thing I could find that provided adequate insulation and
had no issues of smell, fibres, density, flexibility, ease of use,
resistance to smog, rot, etc., etc.
Believe me, I evaluated everything from glass fibre to wool to wood to
neoprene to felt to styrofoam to urethane foam to foil 'bubblewrap' to
ceramic mat to ...
I have a 24 x 17 piece with a 6" diameter hole in one corner if anyone
is interested. Will easily do another machine.

What's wrong with the professional grade ceramic felt? Cuts with scissors,
amazing insulation cabalities, 25 bucks for a few square feet.

Not sure if this is the same thing, but it didn't give me warm and
fuzzies for ceramics

I appreciate the link, but I'm not working with it on a daily basis. If I
had had the link before, I would have worn a mask while cutting (for five
seconds) the felt, and I would have wrapped the boiler outside instead of in
the kitchen. Otherwise, I don't think any particles are shedding inside the
Giotto.
I admit that when cutting it, there probably were invisible particles. But
now?
Anyway, it's very good insulation, and easy to cut relatively exactly.

Yeah, they had other stuff on that page that might work for much less
money. I don't think it needs to be FDA approved unless it's *inside*
the boiler.
