Unfortunately this response is not going to be much help for you
however for the group, we have solved this problem a few times by
insulating the slab under the in-floor radiant heat with one of our
multi ceramic insulations. Here is a link to some pictures of one of
Granted this is not the optimum application for this technology. See
the Note at the bottom of the page!
ie. NOTE : In this particular application the SUNSHIELD 2000 is
completely buried in concrete and consequently only 2 of the 4
ceramics will come into play. The 2 reflective ceramics are
ineffective in this type of application because the coating is facing
direct contact, low temperature, front side conduction. This will
reduce the R value equivalency to approximately R10. Additional R
value equivalency can be achieved by adding more thickness.
An addition 7 mils DFT will only equal an additional RE3.
Prior to the application on the first project I worked with the
Engineering Firm involved and we completed a successful test of this
method of insulation using thermocouples buried in the test slab as
well as taking top and underslab temperature readings.
Hopefully this information will be helpful to others that are faced
with the lack of space constraint.
I tried ceramic paint additive and found no r value using an IR
thermometer on painted heating ducts. I like to see an INDEPANDANT
test of R value. on your product
I used 1 " R 7.2 foamboard under my concrete basement floor , that is
proven to work. But a perhaps better way would be using a natural
product such as pearlite , but something harder
As I recall, soil has a thermal resistance of about R10, so
it looks like your 14 mils of miracle stuff adds about R0.0,
as anyone knowing some physics might expect from its thickness.
You seem extremely confused, if not a serious crook, exceeding
HVAC criminal standards by a very large margin.
