First of all, it is sometimes suggested that all Ceramic Coatings are the same. This is not true. That's like saying all “air trapper” materials are the same which is also not true. Fiberglass is certainly not the same as Closed Cell Foam. First and foremost it should be understood that all ceramic coatings are not the same and are not created equal. Also there are substantial differences between a reflective paint which only addresses Visual Light (short wave) and a thermal barrier coating which addresses UV, Visual Light (short wave) and IR (long wave) with the primary difference being unlike a reflective paint, a Ceramic Coating still continues to work even after it gets dirty.
Even within our own family of Ceramic Coatings we have different coatings that contain different ceramics in different amounts and are engineered to perform different functions.
SUPERTHERM® Multi ~ Ceramic Thermal Barrier Coating contains four different ceramics and is Engineered to Repel Heat and as per its Certifications references ASTM E1269\ASTM E1461-92 and reduces thermal conductivity by deflecting and repelling thermal absorbtance by better than 90% on an interior application and by better than 95% on an exterior application. As noted by a PhD in Fluid Mechanics "SuperTherm® is repelling better than 95% of the heat to begin with therefore debating the remaining 5% with R-value is trivial.".
HPC® COATING Multi ~ Ceramic Insulation Coating contains seven different ceramics and is Engineered to Block Heat and as per its Certifications references ISO 8302\ASTM C177 and has thermal conductivity of 0.063 W/mK and is engineered to block heat and stop thermal transfer via conduction. i.e. A one inch thickness reduces 482°C \ 900°F down to 61°C \ 142°F which exceeds the Canadian standard of 70°C \ 158°F and is virtually compliant with the OSHA standard of 140°F \ 60°C.
Both are Ceramic Coatings but are engineered differently to address different modes of thermal transfer.
Both however do eliminate CUI (Corrosion Under Insulation) and provide CI (Continuous Insulation) and thus eliminate thermal bridging.

The ISBU (Intermodal Steel Building Unit) Association (this is the Association for building construction using shipping containers) have reviewed and tested some of the different ceramic coatings.
Here are two Very Important NOTES from a report by the ISBU Association.
Note: Just buying Cenosphere powder DOES NOT make a proper Ceramic paint insulation. It truly requires a special mix of the Cenospheres and certain proportions of other ingredients.
NOTE: Not all manufacturers of Ceramic Coatings and Ceramic Microspheres are using credible formulas and materials.
OUR NOTE: This is why it is so vitally important to review each product's specifications and certifications in general and CERTIFIED THERMAL TESTING in particular.
Here is a link to some excerpts from the ISBU ASSOCIATION REPORT ON CERAMIC COATINGS which contains some excellent information on this technology and is well worth the read.
As noted in said report:
"Are ceramic coatings an insulation?
Absolutely! But since IBC and other building codes are rated in R-value it is difficult to conduct studies that will comply. R-values are rating thermal resistance related to thickness and not necessarily thermal and insulative efficiency.
Unfortunately the only approved R-value testing methods are according to ASTM (American Society of Testing and Materials) guidelines and to begin a test your insulative material must be a minimum 1" thick. We hope that standard will change soon.
No matter how you look at it ceramic coatings are deflecting heat and reducing "heat transfer" between two objects. To the world of science and also to a consumer that is insulation. But to those stuck on R value and conventional building codes as they are now there is no way to compare.
We are very thankful that microelectronics, superconductors and the new solar cell technology does not require R-factor to use microscopic ceramic insulation in the new chips. If so we would have no PC's, cell phones or other space age technology."
The reason for the minimum one inch thickness requirement is because the R-Value is a “flow through rate”. The R rating assumes 100% absorbtance and then measures “how long” it takes to reach saturation which is why it is thickness dependent. The thicker it is, the longer it takes to reach saturation. Once the “air trapper” material is saturated then 100% of the heat flows through. Ceramic coatings do NOT have a flow through rate but in fact have a blocking rate. The question is, if there is zero absorbtance, how long does it take to reach saturation?
If you are interested in and put credence in testing to non ASTM standards then here is the result of our testing on holding heat in, as in a primarily "heating climate". INTERIOR HOT BOX TEST RESULTS. (At least in our test the building envelope is properly constructed and isn't held together with BUNGEE CORDS allowing air gaps.)
Conversely if more credence is placed in certified thermal tests conducted by certified thermal laboratories then I would invite you to review SuperTherm®'s Certifications.
The first certified thermal test that was conducted for SuperTherm® was ASTM E1269 Standard Test Method for Determining Specific Heat Capacity by Differential Scanning Calorimetry in conjunction with ASTM E1461-92 Standard Test Method for Thermal Diffusivity of Solids by the Flash Method. This was the ASTM testing recommended by Purdue University as it measures the thermal conductivity of the coating independent of the substrate to which it is applied.
As shown in Table 4 and Table 5 the thermal conductivity was reduced from 350+ Btu's on the bare surface (Table 4) down to 4 Btu's on the surface coated with SuperTherm® (Table 5).
The reason the thermal conductivity was reduced so substantially is because SUPERTHERM® significantly reduces thermal absorbtance. In other words the thermal conductivity of SuperTherm® is the same 4 Btu's whether it is applied to wood, metal, concrete, fiberglass, foam or any other substrate.
Of course if the thermal absorbtance was zero then the need for any R rated material would also be zero. The fact that the thermal conductance is still 4 Btu’s means that some resistance to that minimal amount of thermal transfer could still be beneficial under certain circumstances. An example would be in terms of holding heat in on a metal substrate which unlike concrete has no capacity for the mass storage of those 4 Btu’s. One of the next best insulators to retard that minimal thermal flow would be Closed Cell Foam. A one inch thickness would easily slow those 4 Btu’s as well as providing for some mass storage of that minimal amount of heat. This could be considered one of the optimum insulation systems for insulating container construction under arctic climate conditions.
Here is a SCIENTIFIC TECHNICAL EXPLANATION (Heat Transfer & SuperTherm) by PhD Inn Choi who has a PhD in Fluid Mechanics and was one of the PhD's at Owens Corning who designed the R Value formula. PhD Inn Choi also worked with Dr. Raymond Viskanta, W.F.M. Goss Distinguished Professor of Engineering, School of Mechanical Engineering, Heat Transfer Laboratory Purdue University where SuperTherm was first tested as shown above. As noted at the bottom of the document "At any rate, given these values, please note that a 10-mil thickness of SuperTherm is the same as 6” of fiberglass in Thermal Conductivity.".
This testing formed the basis for the letter from VTEC Laboratories, who are a certified thermal laboratory as well as an accreditied BOCA laboratory (Building Officials and Code Administrators). The ONLY reason this R19 equivalency, non real world test is even mentioned is in order to give a basis of comparison in terms of thermal benefit that is familiar. Letter Equivalent R19.
This 90%+ reduction in thermal conductivity was also fairly consistent at all the different temperatures that it was tested at from 23°C / 73°F to 100°C \ 212°F (Table 5), unlike the "air trapper" materials that MUST be tested at 24°C \ 75°F otherwise losing some of its R rating and MUST be conducted in a zero wind and zero moisture environment in order to achieve its listed R rating at all. Where in the real world do you find 0 wind and 0 moisture? This means the R rating test is conducted under non real world conditions and therefore produces non real world results.

Some of the issues associated with some "air trapper" materials are addressed in ASHRAE 90.1. For example Table 402R and Table 402S showing the reduced Effective R Value with metal trusses and framing respectively.
Which would you prefer?
NOTE: In the application shown above, SuperTherm® was applied to the exterior only and the heat source was coming from the interior side. Consequently there was 100% absorbtance of the heat into the interior side of the metal roof. That 100% absorbtance then transferred through the metal via conduction and consquently only the 2 non conductive ceramics contained in SuperTherm® were in effect. The 2 reflective ceramics were not being utilized and consequently SuperTherm® in this orientation is only an R9 equivalency in terms of thermal benefit. If SuperTherm® had been applied to the interior side and thus facing the heat source all four ceramics would have been in effect and the R value equivalency would have been 19 in terms of thermal benefit.
SuperTherm is not affected by metal trusses nor metal framing which is why it is often specified by architects, engineers and building envelope consultants to be applied to steel studs, beams, aluminum window frames, etc.. As noted by a PhD in Fluid Mechanics “Typically the studs are not covered by Fibreglass insulation thus allowing a very high conduction path. The heat loss through these studs can be 30-50% depending on the size of the studs and temperature differential between inside and outside. Naturally, the losses are higher in cold climate. Covering these studs with SUPERTHERM® will help to cut down the heat losses significantly. Consider the fact the thermal conductivity of steel is up to 46 (W/mK) while it is about 0.6 (W/mK) for SUPERTHERM®. This is 76 times less. So it is very smart to spray SUPERTHERM® on these studs and possible on joist and support beams. This is one smart way of preventing big heat losses with a small amount of SUPERTHERM®.”.
Another issue addressed in ASHRAE 90.1 is the effect of compressing the 6 inches of fibreglass required to achieve an R19 rating into the 3.5 inch cavity available in 2 X 4 construction. This is addressed in Table 402T.
This addresses the issue of the client thinking they are paying for and receiving R-19 when in fact they are only getting an Effective R-Value of R-13 and this only if using wood framing. The Effective R value is even more significantly reduced by a further 63% - 67% with metal framing as shown in the Tables 402R and 402S referenced above meaning in that instance the Effective R Value is only R-7. These ratings also do not reflect the effect of any moisture content whatsoever which would further reduce thermal performance to R-4.5 @ 1.5%.
It is easy to see how and why 10 mils DFT of SuperTherm easily out performs 6” of fiberglass let alone the 3” required by the current code for tilt up concrete construction.
Another significant certified thermal test undertaken by SuperTherm® was ASTM C236 (C236-89(1993)e1) - Standard Test Method for Steady-State Thermal Performance of Building Assemblies by Means of a Guarded Hot Box. This test was asked for by Bombardier to find a better material than fibreglass to use for insulation on their train cars. Bombardier continues to benefit from using SuperTherm®. This test shows thermal conductance of 0.31. when SuperTherm® is coated on the interior and thermal conductance of 0.21 when SuperTherm® is coated on both sides of the substrate. ASTM C236 is referenced under Laboratory Tests in ASHRAE 90.1. The test was supervised by VTEC Laboratories a certified thermal laboratory and an accredited BOCA (Building Officials and Code Administrators) laboratory, conducted by National Certified Testing Laboratories and served as the basis for the letter from McQuaig and Associates Engineering Ltd. again verifying the R19 Equivalency in terms of thermal benefit.
Another certified thermal test is the ECAP-CUL-1-03 - ENERGY CONSERVATION ASSISTANCE PROGRAM - Standard Method for Comparing Utility Loads in Standard Constructed Buildings showing a side by side comparison in a climate closest to Canada being Denver Colorado: ECAP REPORT - PDF (1.73 Mb).
This reduction in thermal conductivity has a significant effect on heating and air conditioning requirements. As noted after the third test "This is the third time we have had the pleasure to test your product, it is rare that a single product will show such Repeatable Results in three totally different environments, South Florida and Denver Colorado and LaPorte Texas a true testimonial to your products ENERGY STAR rating." Alexander Othmer - Director
Here is another certified thermal test from Germany again showing that SuperTherm® meets their energy code. SuperTherm® was applied to the INTERIOR of the building envelope as Germany like Canada is primarily a "heating climate".

Super Therm is in use world wide by some major corporations.
Sony Engineering in Japan recorded a 13 month ROI (Return On Investment) at their Koda factory. (SONY ENERGY SAVING AWARD-ROI PDF). Nissan coated one roof at 2 million square feet. (NISSAN FACTORY - TWO MILLION SQ.FT). These companies have come to the realization that the most effective means of reducing thermal transfer is by reducing the amount of heat available to transfer. These are smart companies that are saving substantial amounts of money.
North America is playing catch up in benefiting from this technology which is ironic considering it is NASA technology to begin with.
Here is a HOME AND GARDEN ARTICLE PDF showing the results when the correct ceramic coatings are applied correctly to the exterior and interior of the building envelope in a primarily "cooling climate".
Here are those same ceramic coatings being applied correctly to the interior and exterior of the building envelope in a primarily “heating climate”.

These are just a few of the numerous satisfied customers and successful Projects world wide.
It is a technology that has proven its value by an informed, intelligent and objective evaluation.
The final point that I would like to make is that unlike certain "air trapper" types of insulation which also trap moisture and lose insulation value when moisture is present, SuperTherm® does not trap moisture and does not lose insulation value when moisture is present. This is important because moisture is a thermal conductor, not a thermal resistor and has a substantiated negative effect on thermal performance.

As per its certified ASTM testing, SuperTherm® is not only a thermal barrier but also a moisture barrier and actually helps prevent condensation and the resulting corrosion or efflorescence. This is just another one of the many benefits that SuperTherm® brings to TILT UP CONCRETE INSULATION and numerous other applications as per Architectural Specifications "where Ceramic Coatings can be applied to metal, concrete, wood or other substrates where a reduction in thermal transmission is required.".
I would hope that this puts everything into its proper perspective and proves beyond a shadow of a doubt that ceramic coatings are not only a viable option but in fact an excellent technology to provide long-lasting thermal benefits.
From the original product a whole family of products has been developed to meet the varied requirements of different customers. As is the case with all of our coatings, each one is specifically engineered to solve a specific problem under a variety of application and performance criteria.

SCIENTIFIC TECHNICAL EXPLANATION
"At any rate, given these values, please note that a 10-mil thickness of SuperTherm is the same as 6” of fiberglass in Thermal Conductivity." - PhD Inn Choi
EMISSIVITY EXPLAINED & DEMONSTRATED
SuperTherm® consists of a specially tuned compound of 4-different ceramics thermo-dynamically tuned to cover the IR, UV, & Visible Light Spectrum, the Thermal Spectrum from -40°C\F to 149°C \ 300°F; as well as 68% of the Sound Spectrum!
SuperTherm® is a Thermal Barrier NOT an Thermal Absorbent! It stops the thermal vibration continuance by its ultra low density. Fiberglass & Foam Insulation are NOT a thermal barrier, they absorb heat until they are saturated then discharge the built up heat into or out of the structure!
Reflective paint vs. SuperTherm®
Manufacturers in the past have marketed "reflective" paints by making claims that they continuously repel heat, and have specific "R" values. The problem with such claims is that these paints only reflect visual light or short wave radiation, and when they become dirty they stop working completely. Once these claims proved false, all similar coatings were put into the same category and deemed non-viable.
SuperTherm® was designed and developed with the assistance of NASA, a fact that can be substantiated. The "ceramic compound" blends found to work the best, and are now used in SuperTherm®, resulted from 18 years of testing and research. The difference between the technology of "reflective" paints of the past and SuperTherm® today, is outlined below.
Engineering studies performed by the US Government and independent firms, have concluded that the sun's radiation produces heat from the following sources:
• Ultra Violet (UV) which represents 3% of the heat.
• Visual light or short wave radiation represents 40% of the heat.
• Infrared radiation or long wave represents 57% of the heat.
Once these facts became known, the technology of deflecting and repelling radiation was developed using laboratory testing to identify what methods and elements worked best to address these different types of heat.
SuperTherm® has the ability to defect and repel all the different radiation waves. SuperTherm® not only deflects and repels these waves when first applied, but continues to deflect and repel them after the coating becomes dirty, which happens to all coatings. The ceramics used in SuperTherm® were chosen from over 3,200 compounds, which were studied and tested in order to prove that they would deflect and repel the different radiation waves the most effectively, producing the following results:
1. SuperTherm® deflects and repels 99% of UV
2. SuperTherm® deflects and repels 92% of Visual Light (short wave)
3. SuperTherm® deflects and repels 99% of Infrared (long wave)
This results in an average of over 96% of heat absorptance deflected and repelled!
There are few limits to the application possibilities for ceramic coatings. They qualify for anywhere from 2 - 14 points on the LEED (Leadership in Energy and Environmental Design) rating system. They can be used on metal substrates such as mobile homes, livestock barns, grain bins and oil tanks, refrigeration units, trucks etc., to help reduce the HEAT LOAD \ LOSS by as much as 90 - 95%. (Heat Lamp Video Clip). This translates into reduced heating \ cooling needs, less loss of animal life due to escalating ambient temperatures, greater protection for storage contents, greater comfort and increased productivity for personnel and greater life expectancy for the structure itself.
Other substrates likewise, enjoy greatly reduced temperatures, from metal pipes in the industrial field to the concrete surrounding the family swimming pool or anything that people come in contact with.
Additionally, as part of a roofing system, there is no comparison for SuperTherm®'s ability to withstand basic weathering for 20 - 25 years minimum, resisting everything from the normal stresses of expansion \ contraction, to hail stones, to ponding water, to UV's. Besides normal insulation uses, the combination of RUSTGRIP® and SUPERTHERM®, can survive exposure to the inner workings of an acid incinerator to stop the heat and dripping acids from corroding the steel walls. All this with a USDA-approved, environmentally safe formula that lends itself to possibilities limited only by one's intellect and imagination.
In the US, Hoechst-Celanese Chemical Plant in Houston, Texas had been having problems with keeping their hazardous waste incinerators (operating @ 870°C \ 1600°F) online due to the heat and dripping unburned acids (during the cooling on shut down). The combination of heat, condensation and unburned acids caused the bottom of the incinerator to totally corrode, forcing complete replacement approximately every 4-6 months. Costs exceeded $.25 million USD per shut down for repairs and lost production which occurred twice per year.
The engineer decided to try using our RUSTGRIP® primer and then SUPERTHERM® as the top coat at 30 mils DFT to protect the skin of the incinerator from the heat and effects of the condensation and acid. They were applied in February 1992, and to this date, has not required downtime due to corrosion of the skin.
During this time period, approximately $6 million USD has been saved in downtime alone by using the designed protective coating system. SuperTherm® was tested and approved by Ontario Hydro in Ontario, Canada as the most effective insulator available for their tanks, pipes and buildings. Infrared video was filmed showing the effectiveness of SuperTherm®'s insulation ability over fiberglass, polyester foam, white paint and other types of conventional insulation by visually demonstrating the escape of heat for the protected surface. SuperTherm® outperformed all other insulation materials.
The blast furnace door at the GVRD waste incinerator was coated with 28 mils DFT of SuperTherm® to bring the surface temperature down from 150°C \ 302°F to 70°C \ 158°F to meet Canadian codes for any surface exposed to human contact. After coating but before full cure a check was made with the computerized control room and the operator immediately cut back the jets due to the increased heat retention again paying for itself in reduced energy consumption. Today we would use HSC® COATING which had not yet been developed and accomplish the same thickness in one coat.
As reported in Rink Magazine SuperTherm® is substantially reducing utility costs on various arenas.
As stated by director Dwayne Lowdermilk, National Training Rinks (pre-engineered stress skin metal structure) experienced a
"30% reduction in utility costs; which we sure appreciate".
As noted by Kirk Fisher, P. Eng. , MBA, and the Development Manager for the Lark Group, the application of $30,000 of bulk insulation (foam) at the Excellent Ice facility (pre-engineered stress skin metal structure) located in Kirland, PQ and "the gas and hydro bill didn't change at all". The SuperTherm® was doing all the work and consequently it is specified on the Surrey, BC expansion and all other ice arena developments.
Energy Efficiency Project Analysis for Supermarkets and Arenas
On the Alberni Valley Multiplex (tilt up concrete) a system of SUNSHIELD® and SUPERTHERM® was applied. In May 2002 the first year audit was completed on this facility and of special interest was the fact that the cycles on the compressors were far below expectations thus resulting in major energy savings as well as longer life for the equipment itself!
At the Bonaire Golf Club the application of SuperTherm®"saved the purchase of another air conditioner plus all its related energy and maintenance costs, plus we are using the existing two units less and our building is more comfortable. Your product will help Ontario's energy problem."
To date more than 15 million square feet of roofing has been protected in Japan alone using SuperTherm® for such companies as Canon, Hitachi, Kirin Brewery, Matsushita, Mitsubishi, Sony, Sumitomo, and Nissan to name a few. 2 million square feet of SuperTherm® was applied to the Nissan Factory Roof in 2004. Sony Engineering group conducted field studies at the Koda factory and determined that the kW usage was reduced from 3,764 kW in May 1994 to 519 kW in May 1995 a reduction of 3,248 kW or 86%. The kW usage in June 1994 was 5,647 kW which was reduced to 1,869 kW in June 1995 which was a reduction of 3,778 kW. This resulted in a payback of 13 months.
As a consequence SuperTherm® was specified on their new 700,000 square foot facility in Malaysia.
SuperTherm® was applied on a manufacturing facility in Kansas that was experiencing a great deal of difficulty in cooling various unconditioned buildings of the factory due to variance in size and significant volume. The results were an immediate reduction by 12 degrees Fahrenheit on the lower levels, with an even greater reduction to the attic storage and overhead work zones on the second story. This temperature reduction enabled the facility to utilize simple ceiling fans for cooling during the summer months, and thereby lowering the overall expense of energy.
SuperTherm® is being applied in numerous areas in the Transportation Industry. It is reducing the fuel consumption on Reefer units by 30%. It is being applied to all the UPS trucks. It is specified by Vancouver Shipyards on all new construction to control condensation such as all the passageways on the new Kootenay Lake Ferry. It is applied to the interior of Yachts for acoustical insulation as well as to increase comfort. It was also applied to the exterior superstructure of an Oil Tanker for thermal control. On a Casino Ship it was applied as a base coat for moisture impervious insulation.
HPC® COATING was successfully applied at the Gazprom Refinery in Omsk as an insulator in order to maintain internal heat, to reduce the melting threat to the tundra, and to aid in the flow of crude oil through severe winters. Chevron Oil is using HPC® COATING to insulate steam valves some running at 315°C \ 600°F, which had never been able to be insulated before. Temperatures have been reduced as low as 57°C \ 135°F. HPC® COATING has seen success in many other industrial Projects.
Uninsulated Tanks putting out Pollution in the form of Evaporation:
These videos show gasoline vapors at a Gas Service Station and a large Storage Tank. The big tank is in Corpus and shows vapors escaping during the day, The seal being weak in this case. These pictures were taken with a top of the line $100,000 infra-red camera. This seems very appropriate for Valero. I got these from a visit with Agent's from TCEQ-Texas Commission for Environmental Quality. Who are involved with all environmental compliance in Texas.
As noted by J.E. Prichet President Superior Products International II, Inc. "This was exactly what I worked with the Diamond Shamrock group back in the early nineties and found to be the case. This is the reason the boots were put on the gas nozzle at the pumps was to hold the fumes from escaping so easily. At that time, it was estimated that 25% of the actual air pollution was from gas fumes. At that time, gas was cheaper and no one cared. Now is different. When we coated the tanks with SuperTherm®, we stopped practically 100% of the evaporation due to heat build up on the tank. What evaporation did happen was very little and only the fumes that are associated with gasoline in its liquid state. Now, gas is expensive and this is more of an issue.
What happened during this time was that evaporation was not important but the cost of blasting and recoating tanks every 4.5 years was. We could do a RUSTGRIP® / SUPERTHERM® in place of the blast, zinc primer, epoxy middle coat and urethane final coat and save a total of $300,000,000 over a 10 year period covering a 3000 tank field. Stopping evaporation at the time was only going to save $30,000,000 so it was decided to not be important. This $30M was at the pricing back then. It has tripled today. Now, it is important." SUPERTHERM® has been specified for various Projects.
SuperTherm® has many cost-reducing, profit-enhancing Agricultural benefits. Testing has shown the use of SuperTherm® on Farm and Poultry houses greatly lowers inside temperature and humidity levels, which reduces the death-rate of livestock (due to heat stress) by up to 75%. Cooler Farm house temperatures allow for regular feed consumption by livestock, which helps to increase average livestock weight and profits.
Condensation and moisture inside a Farm house quickly deteriorate existing insulation materials, and can be a breeding ground for disease. SuperTherm® on houses and cold water pipes will eliminate condensation and moisture, extending the life of existing materials and preventing loss of livestock. Use of SuperTherm® on Bin Feeders also prevents condensation and moisture contamination of the feed, resulting in less feed waste.
A worldwide construction company based in England has specified SuperTherm® and is applying it around the world on jobs from South Africa to Asia where insulation is needed and the batt-style cannot hold up to the weathering conditions and applications. Numerous Canadian construction companies have also specified SuperTherm®.
