ASTM C-236 Testing for an “ R “ rating.
Post Test Review

SUPERTHERM® C-236 Full Test Report

We have discovered that having an " R " rating means the material absorbs heat and is a measure of how long it can absorb and hold heat before it can migrate through it. R-value = Flow Through Rate. This test measures CONDUCTION only and does not account for RADIATION or CONVECTION. It MUST be conducted in a ZERO moisture \ ZERO air movement environment.

(See further explanation below).

The various ceramic compounds contained in SUPERTHERM ® do not absorb heat but in fact repel heat in a manner similar to reflection. SUPERTHERM ® is not affected by wind or moisture in any way and retains its insulation value ( nondeteriorating ).

In the effort to answer the question of how do we measure up to an " R " rated material as in fiberglass, we took on the ASTM C-236 ((C236-89(1993)e1 Standard Test Method for Steady-State Thermal Performance of Building Assemblies by Means of a Guarded Hot Box)) testing for measuring R-values. The resistance from other engineering groups was that a known and accepted ASTM test had not been performed to compare the " R " values.

ASTM C-236 K value \ R value Results

This test specifies a 3 " fiberglass board be used as the control panel and tested. Then the board is tested with one coat of SUPERTHERM ® applied to one side. Another board is tested with a coat on each side of the board.

The control board of the same 3" of fiberglass was tested and gave a .52** numerical value.

The board with one coat of SUPERTHERM ® at 10 mils DFT was tested and gave a .31** numerical value.

The board with two sides coated with the SUPERTHERM ® at 10 mils DFT per side gave a .21** numerical value.

** These are exact numbers for BTU heat conduction per sq. ft. / hour / °F.

The lower the number the better the insulation.

Based on the high density fiberglass board and figuring the math on a linear* basis:

* The results are greater than the linear result as insulation is a compounding value and not just linear because heat comes from different sources and by different methods of transmission. The repelling of radiated heat, the reflecting of convective heat and the resistance to the migration of conductive heat with any substrate is a compounding formula, but for now the linear math will give you the minimum of what can be expected.

3 inch high-density fiberglass board tested: k = 0.52 (Btu inch/hr sq.ft °F)

10 mils of SUPERTHERM ® tested: k = 0.31(Btu inch/hr sq.ft °F)

20 mils SUPERTHERM ® tested: k = 0.21(Btu inch/hr sq.ft °F)

Most all insulation guidelines are currently built on fiberglass claims and calculations. These claims are short sighted, disputed and can easily be shown invalid. This, of course, leaves the engineering and architectural groups with a responsibility for determining true and accurate numbers to be used for quotations on insulation requirements for buildings and facilities nationwide and worldwide under their review. The ASTM R-test was designed by a committee to give us measurement values that hopefully would be meaningful. However, the test does not account for air movement (wind) or any amount of moisture (water vapor). In other words, the test used to create the R-value is a test in non-real-world conditions. If a fiberglass is assigned an R19 value, it can achieve this R-value if tested in an absolute zero wind and zero moisture environments. And zero wind and zero moisture are not the real world. If normal industry fiberglass is at 1½% moisture content then the R value will immediately reduce by 35% as tested by industry results (Innovative Insulation, Inc. magazine report, Canadian Roofing Association). Water is a better conductor than resistor! This would mean that as soon as you opened the bag of fiberglass you would have a minimum of 1 ½% moisture (ie. breathing on it) and more already in the material, meaning it would not be more than R12. Given its ability to absorb this moisture, the fiberglass is worthless in a matter of days. Also, when you see the fiberglass packed down, rolled into a tight roll or compressed in any way, the "R" rating has been drastically reduced. This issue has been addressed in ASHRAE 90.1 Table 402T. Fiberglass must have all of the inches in depth or thickness as stated for "R" rating without reduction to be as advertised. Here again, SUPERTHERM's ® insulation ability is not affected by moisture, wind or compression in any form once cured and therefor will not reduce it's effectiveness as shown in the testing and field studies (see reports).

Our personnel discovered another note of importance when working with the labs to do the testing and comparison against the fiberglass.

First, all fiberglass testing must be performed at 75°F.

Why, because this is the optimum temperature that the fiberglass can test and give the best results (Owens Corning did have the advantage of being involved when the original R value formula was designed and based it on a formula that would ENSURE the best result).

When asked why this is the situation, it was stated that if the temperature drops below or rises above 75°F, the fiberglass will suddenly drop in heat conductance value and therefore drop in its R value very quickly. Extreme heat ie. 212°F (100°C) cuts through fiberglass like a hot knife through butter. SUPERTHERM ® reduced BTU heat conduction from 367.20 BTU/sq.ft. /Hour/°F down to 3.99 BTU/sq.ft. /Hour/°F in the ASTM E1269 Specific Heat and ASTM E1461-92 Thermal Diffusivity and conductance testing at 212°F. This result is written as being the same for metal or concrete surfaces, which is to say any substrate. Full-scale attic tests conducted at Oak Ridge National Laboratory show that at –18°F (-28°C) R19 insulation drops to an effective R9.

This seems very odd that an entire industry would accept such a material that only works best at one level of temperature and then base all the insulation requirements on a temperature level that is rarely achieved on any consistent basis.


This gives a different meaning to the numbers reported on the test results. When SUPERTHERM ® improved the performance of the fiberglass by 40% with only one coat, this was at the 75°F level. SUPERTHERM ® has performed worldwide at all temperature levels from -60 °F up to 212°F and given the same insulation values (see reports and testing results on the Website). The reflective driven ceramic compounds in the SUPERTHERM ® have only been marginally used in this test at only 75°F. When the heat climbs to higher levels is when the IR and reflective ceramic compounds tend to kick in to provide even better results. SUPERTHERM ® is loaded with four different ceramic compounds that work on all " windows of heat and light spectrum ". The understanding that heat comes in several different forms is the reason SUPERTHERM ® is designed with a very unique blend of ceramic compounds that can react effectively to each heat source. According to the labs, VTEC and NATIONAL CERTIFIED TESTING LABORATORIES (NCTL), the percentage of improvement in R value above and below the 75°F level will increase dramatically to give SUPERTHERM ®, as a single insulation film, the comparison of a minimum of R19. In addition, if reflectivity, emissivity and thermal conductivity are included a further R19 is achieved as noted in the letters from VTEC and Purdue.

VTEC labs in New York made the applications on the test panels. NATIONAL CERTIFIED TESTING LABORATORIES in Pennsylvania certified by ASTM did the ASTM Testing. This testing was asked for by Bombardier for Train Cars to find a better material than fiberglass to use for insulation on their train cars.

Now, this has been done and we show to be the effective R-value that we have always stated in our literature from the compound formula results. This test was performed for the specific reason to prove that the SUPERTHERM ® is an insulation material used in the building and construction industry.


Totally repel radiation

SUPERTHERM ® is most effective when coated on roofs and ceilings. It repels more than 95% of radiation to begin with. This ability alone is sufficient to beat fiberglass as the most effective heat barrier. Therefore debating the effectiveness of conduction heat transfer with R-value for the remaining 5% of energy input into or out of a building is not practical. Besides, R-value comparison without taking real-world conditions into account is totally meaningless. In addition although UV radiation only contributes 3% of the exterior heat load; it is the primary contributor to roofing failure. SUPERTHERM ® blocks better than 99% of UV radiation.

Prevent air penetration, free water, and moisture

In a nutshell, it is very likely that insulating the roof and or ceiling can handle more than half of the insulation needs for the entire building. This is because the primary heat transfer in nature always takes place vertically, i.e. hot air goes up and cold air comes down. Therefore roofing insulation is much more effective than sidewall insulation. By applying SUPERTHERM ® on top of roofs and, if necessary, in the attic or on the ceiling, air penetration can be stopped, free water can be blocked, and moisture migration can be prevented.

Condensation Protection (Rust, Rot, Mold, Mildew)

SUPERTHERM ® will not allow condensation to develop because it contains certain ceramics that repel heat therefore not allowing “dew point” to be reached. The ceramics bond tight to the substrate surface preventing the passage of moisture, air and atmospheric conditions to affect the surface. In all fiberglass wrapped pipes found in industrial or petrochemical plants, the pipes are all corroded when the fiberglass is removed (CUI or Corrosion Under Insulation is a known problem). Fiberglass breaths the air, moisture and conditions into the air pockets and holds this mixture causing the surface of the pipes walls, etc. to become corroded in a short amount of time. Condensation on vapor barriers is also a known problem. This causes rot \ rust and sometimes-toxic black mold, which creates indoor air quality issues. Unlike fiberglass, which DEMANDS that a vapour barrier be used to protect it, SUPERTHERM ® is its own vapour barrier. This means that the vapour barrier is always facing the warm side.
