Insulating Paint ???
Chgrowth
It is said to have ceramic hollow microspheres in it
and to add the equivilent of R20 insulation.
Has anyone used it????? What did you think???
Worth the $$$'s?????
E-mail or post please
thanks

radiant (infrared) heat that strikes the wall. Most heat is lost through
convection and conduction so I would suspect this paint would not do much.
This would explain why 3o years of research into various energy saving
alternatives have not resulted in wide spread use of reflectant surfaces
inside the home.

There is no way that a paint is going to give you R20. I wouldn't expect it
to give you much higher performance than styrofoam, which (IIRC) gives about
R9/inch.
Chgrowth
they claim R20. I have read the test specs and results. Seems amazing to me
to.
Can anyone substantiate????
Has anyone had good results???

According to the website for INSULADD, the SURFACE temperature of the
walls was 2-6 degrees cooler (tending to 3-4) over all their tests.
That may be an improvement, but it don't sound like no R20 to me!
They talk about radiative improvement, but not a whole lot about
conductive.
I looked at a few sites:
INSULADD - www.insuladd.com
I'm not an expert, really, but (*in my opinion*) it just looks a
bit.... scammy to me. You know? The site is kinda heavy
on "infographics" and buzzwords, but not really much else. I'd be wary.
Also note in the FAQ it says:
<<QUOTE>>
Q:Can I paint over Insuladd at a later date?
A: Yes! However a slight decrease in performance may result.
<<UNQUOTE>>
Which, from a salesman's mouth, means it will be a bugger to paint
over. Careful...
THERMAL CONTROLS - www.thermalcontrol.com/insulate.htm
Well, first they say "better than R20 foam", they they say "equal to or
exceeding..." (which means barely equal to) "...R5 when used on
interior walls *and ceilings*." Very vague on the old promises. The
tests are not documented or clear. Was the other building black? Who
knows?
INCA COATINGS - www.incacoatings.com
This was a GREAT SITE. It is an industrial paint and coatings place.
It has the info on this kind of paint, but note that they are for use
on vehicles and stuff, and they design the whole paints, not just an
additive. Check this out: (heavily edited for length)
<<QUOTE>>
CH-201 is most effective against radiant heat energy, typically
blocking transmission of +90%. A nominal 5 mil (128 micron) DFT coat
is the equivalent of 4 inches (10 cm) of foam insulation, or R-20 [BTU/
(h ft2 °F)] R-3.6 [W/(m2 °C)] against radiant heat gain.
<<UNQUOTE>>
So, a 5 mil (normal coat, according to them, is actually good to R20
**BUT ONLY AGAINST RADIANT**.
<<QUOTE>>
The following are typical results of 30 mils (765 micron) DFT applied
to 10 ga. carbon steel, operating at 200°F (93°C):
Convective – the equivalent of 2.5 in (6.35 cm) of foam insulation. R-
12 [BTU/(h ft2 °F)] [R-2.1 (W/(m2 °K))].
Conductive - the equivalent of 1.5 in (3.8 cm) of foam insulation. R-8
[BTU/(h ft2 °F)] [R-1.4 (W/(m2 °K))].
<<UNQUOTE>>
So, to get even an inch and a half of foam equivalence, you have to
apply **SIX** full thickness coats.
MY CONCLUSION
So, the last site was actually good enough that it made me think that
there actually might be something to this stuff, but they don't
recommend it for much but sheet metal, in thick coats. The other sites
that say they have a cheap and easy additive (but quote the same
effectiveness as the expensive industrial custom paint) are more than
likely crap.
Boy, I have too much time on my hands... but thanks for giving me
something interesting to surf on for a while. :-)
My 2 cents.

Will only work if you also put magnets on your water pipes to
neutralize the particles coming into the house. :-)
IMHO, it is another way to seperate you from twice the money for a
paint job.
