Super Therm® v Traditional Fibreglass Insulation

See the difference between new and old technologies

Old mouldy fibreglass insulation

Fibreglass insulation if exposed to any moisture is both a health risk and inefficient. Super Therm® is water, UV, mould and mildew resistant.

Environmentally better and outstanding results with Super Therm®

With the ability to protect from all 3 methods of heat transfer, Super Therm® is proven to outperform traditional fiberglass insulation. In fact, a layer of Super Therm® no thicker than a single business card provides the same protection as 6 inches of fiberglass.

Moisture content of 1.5% in fiberglass reduces its insulation value effectiveness by 35%, Super Therm® is specifically formulated to prevent moisture absorption. Super Therm® is durable and versatile, with a 20-year lifespan under normal conditions. Neither temperature nor moisture will compromise its performance. Super Therm® outperforms and outlasts traditional insulation in lab tests and in the field.

“Unlike fibreglass insulation, whose R-value rating assumes heat loading by a building and simply measures the rate at which that heat is transferred, ceramic coatings are not given an R-value rating. Instead, they are rated by “emissivity.” a measure of both their ability to reflect heat and the amount of heat that is loaded onto a surface”. J.E. Pritchett – Bob Villa article

Questions on Insulation comparisons

  • What is Blanket or Batt type insulation and how does it compare?
  • How is using BTU meter guns more effective in finding “R” rating than comparing W/mK or other standard heat transmission figures normally used for Batt installations?
  • What is the performance difference between Batt type insulation and Super Therm®?

Blanket Type Insulation – this is Fibreglass or rock wool

For blanket type insulation the insulation or thermal conductivity is based on a minimum of 75mm (3 inches) up to 150mm (6 inches) thickness. To try and use the same W/mK is not correct because of the large differences in thickness required.

From now on, the main point of insulation is based purely on BTU conduction of heat or Heat Flow. This is the measurement used by the energy companies to judge if a material is stopping heat conduction. Heat Flow is the main characteristic that they are concerned with. The comparison of W/Mk is not important between Batt insulation materials and coatings, the most important factor is–does the material stop Heat Flow which is blocking BTU heat flow and how effective is it in blocking the BTU heat flow.

Super Therm® is much better than the Batt type insulation materials in blocking BTU Heat Flow. For example: Using our Heat Flow BTU engineering guns, we measured a roof with fiberglass inside of the roof and another roof coated with Super Therm®.

The ASTM C-236 Heat Transfer (Guarded Hot Box) test was performed with Super Therm® to determine the BTU/in./sq.ft/hour/F and conductivity performance of Super Therm® so that a comparison could be made with traditional insulation.

Fiberglass Super Therm®
Test Temperature Traditional insulation is only tested at 73°F because this is its optimum performance temperature. Rating is established on the batt material and “presumed” good for all levels of atmospheric temperature levels Super Therm® has been tested at different levels of temperatures and in field studies. Its effectiveness is not altered by atmospheric conditions
Moisture Content A moisture content of 1.5% in traditional insulation reduces its effectiveness by 35% Super Therm® has been tested as a moisture barrier. It will not absorb moisture or water
Mould and Mildew Moisture in fiberglass can cause mould and mildew development and thereby create airborne health problems Super Therm® has been tested to resist and prevent mould and mildew from forming on its surface
Sound Transmittal Very little sound deadening qualities. Fibreglass is considered a porous sound absorber that sound can travel through Super Therm® has been tested to reduce sound transmission and to deaden sound waves by up to 68%
ASTM Tests* ASTM C-680 Test on “High Temperature Pipe Insulation 1200” Heat level: 200°F allowed 11.8 /in. /BTU /sq.ft. /hour /F to conduct through fiberglass ASTM E1269 Specific Heat and ASTM E1461-92 diffusivity tests on Super Therm® Heat Level: 212°F allowed just 3.99 /in /BTU /sq.ft. /hour /F to conduct through coating

These results are astounding! Super Therm® is 296% more effective than traditional insulation under identical conditions and shown to be stable all day in field studies by Sony, UPS and others. *Tested by Owens Corning Insulation for Mechanical Systems 2002. Source

Two different readings are made with the BTU gun

1. BTU reading is taken on the interior wall to find the ambient heat load inside the building. Then a reading is taken on the roof interior surface to find the amount of BTU heat flow coming through the roof. You subtract the ambient BTU load from the BTU Heat Flow coming through the interior of the roof to find the BTU Heat Flow per sq. ft. per hour.

2. BTU surface heat measurement on the surface of the exterior of the roof and the interior of the roof to show the difference in the surface measurement of BTU heat on the surface to find the amount of BTU heat transmission from exterior to interior side of the roof.

a. The fiberglass roof showed BTU conduction of 4.8 BTU per sq. ft. per hour.
The top of their roof was 94.4°c (202°F) and interior side was 68.3°c (155°F), which is a blockage of 47 BTU units of heat transmissions.

b. The Super Therm® roof showed BTU conduction of 4.3 BTU per sq. ft per hour.
The top of our roof was 94.4°c (202°F) (because the heat is being thrown back to the atmosphere and records hotter above the coating surface than is the metal roof) and the interior side was 61.1°c (142°F), which is a blockage of 60 units of heat transmission.

Therefore: In BTU blockage of Heat Flow Blockage of Heat unit transmission:

  • Super Therm® 4.3/sq. ft. per hour 202 – 142 = 60 BTU transmission block
  • Fiberglass (Low E) 4.8 sq. ft. per hour 202 – 155 = 47 BTU transmission block
  • Performance Comparison 12% better (Low E) vs. 28% better (Super Therm®)

Super Therm® outperformed the Batt Type Insulation

This BTU testing was performed on a Major Distribution center in Texas.

The readings on the Super Therm® when plotted on the Omega R value chart give an R18 rating. Low E plotted to an R11. BTU readings are the backbone of insulation measurements. Reflectivity, emissivity and visual light bounce cannot relate to heat transfer and BTU Heat Flow. Measurement standards and calculations used to evaluate Batt type insulation material cannot be used with ceramic insulation coatings because the Batt is calculated to absorb heat and ceramics repel heat.

Batt or Blanket type insulation is designed to absorb and load with heat during the day. The reason that this type of insulation material must be so thick is because as the day progresses, the heat absorbs into the material, the thickness must be thick enough to absorb and hold the heat before the heat is able to penetrate totally through the material and come to the inside of the building.

As heat builds up during the day, the heat absorbs into the Batt and migrates through and comes into the building in the afternoon. When this happens, the heat that has been absorbed into the Batt is hotter than the heat inside the building. The trapped heat inside the building cannot get out of the building because it cannot migrate through the Batt until late at night when the Batt material cools down and then the trapped heat inside the building can migrate back through the Batt to be released back into the atmosphere late into the night.

The Batt is inefficient because any moisture or humidity as little as 2% of humidity can reduce the insulation ability of the Batt by 35%. If a Batt is rated to be a R19 and 2% of moisture enters the Batt due to convection, which is normal within the first month of installation, the efficiency is reduced to R12. The more humidity that is absorbed the more the efficiency is reduced.

The Super Therm® is never affected by moisture or humidity after it is applied and cured. Super Therm® does not absorb heat. It is not designed to absorb heat and therefore this is why we do not need thickness. You only need thickness if the material is designed to absorb heat. Since the ceramics repels heat from the surface of the coating, no heat is ever absorbed and it limits the migration of any heat through the coating. When the sun goes down in the afternoon, the building can quickly cool down because no heat has been absorbed and is being held in the building as in the case of the fiberglass which does absorb and holds heat. This quick cooling allows the Air conditioning units to shut down faster and save energy on a daily basis.
