8,000 square foot house located in Kitsilano, overlooking English Bay, will be heated on all 3 floors with infloor radiant heat
Because of inclement weather, the local ambient temperature and relative humidity, a tarp was used to cover the house during the
SUNSHIELD ® coating process.
NOTE : In this particular application the SUNSHIELD ® 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 thermal barrier for SUNSHIELD ® and 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 insulation effectiveness can be achieved by adding more thickness. This is amply demonstrated with our new HPC® COATING when the surface temperature can be reduced from 1000°F to only 163°F with a mere 1" DFT as certified by the TEMPERATURE REDUCTION CHART - VTEC LABORATORIES.

Bill recently ( October 2005 ) applied SUPERTHERM ® Multi ~ Ceramic Insulation Coating as the thermal break under newly installed in floor radiant heating. His results match the results achieved on our projects.
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.
