SUNSHIELD 2000 ®
NONDETERIORATING Multi ~ Ceramic
Insulation Coating
applied as a thermal break under infloor radiant heating.
(see
NOTES )
Bare Concrete Slab
SUNSHIELD 2000 ® applied on slab @ 16 mils WFT \ 7 mils DFT
Glue applied to the bottom of the piping rails
Piping rails in place
Heating tubes placed in rails
Concrete skim coat applied over entire system
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 Effective R value to approximately RE6 for SUNSHIELD 2000 ® and RE9 for SUPERTHERM ® as demonstrated by the ASTM C236 - " Steady State Thermal Performance of Building Assemblies by means of a Guarded Hot Box ". A Reflective Paint on the other hand wouldn't work at all in this application and is a further demonstration of the difference between a Reflective Paint and an Insulating Coating. Additional R value Effectiveness can be achieved by adding more thickness. This is amply demonstrated with our new HOT PIPE COATING ® when the surface temperature can be reduced from 1000F to only 163Fwith a mere 1" DFT as certified by the TEMPERATURE REDUCTION CHART - VTEC LABORATORIES.
In an independent test conducted in 2001 by JSA Sales a 10F difference was recorded using SUNSHIELD 2000 ®.
The following is courtesy of Don Pasternak of PRAGMATEK BUILDING SYSTEMS, INC. the distributor for New Jersey. Don is working with Bill Barbera the Vice President of HVAC Alternatives, Inc. Bill recently ( October 2005 ) applied SUPER THERM ® Multi ~ Ceramic Insulation Coating as the thermal break under newly installed in floor radiant heating. His results match the results achieved on our projects.
" I have performed some
additional tests on supertherm ® . Recently I installed radiant on the 2nd
floor of my own home.
One room I coated the sub-floor with 2 coats Supertherm
® Installed 9" wide sleepers & heat transfer plates with 1/2"
pex then Pergo for finished floor.
The rest of the rooms was installed
using 3/4" Dow Polystyrene with heat transfer plates and pex, simulating
the Roth products system for radiant retrofit systems in lieu of the supertherm
® and plywood.
The Supertherm ® room responds twice as fast, with
virtually no heat loss
My Conclusion:
1- I had to reduce the flow to that room to prevent fly wheeling and overheating
2- I wish I used Supertherm ® throughout.
3-Supertherm ® is far superior than conventional insulation.
Supertherm ® is truly an amazing
product. I intend on specifying it in all future energy conservation projects.
