Technology of thermoceramical membrane:The main components of heat insulating points are vacuumed microceramic
hollow particles (Ceramic Bubbles) that contain inner gas inside. These ceramic microballs have absolutely minimal
warmth conductivity and at the same time maximal heat reflecting performance. They are able to distribute themselves
regularly in the structure of the coating and create so a uniform ceramic membrane. When using different kinds of
ceramisc these microballs put themselves into regular layers.
Creation and progress of Super Therm® technology®The most successful usage was achieved in NASA when trying
to develop a heat shield for space shuttles that thanks to the thermoceramic technology resisted extreme heat
On the basis of this the producer SPI II Inc. USA has decided to collaborate in developing of their main product Super
Therm® with the research centres (NASA). Successful development of the insulating coating with inimitable
characteristics succeeded in particular thanks to collaboration of the scientists and ceramic engineers from Marshall
Space Center (NASA). After 2 - year - testing of more than 600 different kinds of ceramic components 3 ceramics
with the greatest ability of radiation reflection and the smallest heat conductivity were ultimately selected. Later
researches proved inevitability of blocking also infrared radiation. Therefore the fourth ceramic membrane was added.
Applying knowledge from space enviroment a unique thermoceramic coating for civil usage was created.
The developers of the Super Therm® coating accomplished their most important task - the coating provided not only
the heat reflection like other ceramic "heat - reflecting" coatings on the market but also blocked all the heat transfer.
Super Therm® thus contains not only one reflecting ceramic membrane, but four different ceramic membrane:
two are reflective - they blocked up to 95% of the solar and radiation heat
one acts as a dead air space that avoids conduction of heat or cold.
The fourth one blocks up to 99,5% of infrared radiation
The patented four ceramic membrane enables Super Therm® to be a real "insulation shield" and not only a "heat
reflector" like common ceramic coatings. Super Therm® was tested and applied in NASA Space Flight Center as the
only commercial thermoceramic coating. The developers of Super Therm® rely upon the latest scientific research of
Basic principles of Super Therm® insulative properties High-performance thermal reflection + low absorptive
emissivity + high radiative emissivity + conductive resistance = the splendid thermal insulation Super Therm®
The principle of operation of Super Therm® thermal insulative coating is based on thermal reflection, very low
absorptive emissivity and its ability to very quickly dissipate unreflected residual heat while simultaneously blocking
its transfer to the surface beneath.
The essential ingredient of the coating is special hollow ceramic micro-balls 50-100 microns in size which give the
material its thermo-reflective and thermal insulative properties. Ceramic materials are very poor conductors of heat,
and excellent insulators.
Super Therm® contains 4 types of ceramic.
Ceramic ingredients function as a “heat and light mirror”.
1 ingredient works as a blocker of infrared radiation.
1 ingredient, the hollow ceramic balls, functions as a vacuum gap (comprised of numerous miniature “thermoses”).
Thermoreflection – the ability to reflect thermal radiation:
Every material absorbs some energy and reflects the rest back. Ordinary coatings or building materials reflect back
only around 30% of thermal energy and absorb the rest into themselves. Moreover, as a result of their high
absorptivity, heat accumulated in them over time leading to a gradual increase in temperature.
Super Therm® thermoreflective insulative coating reflects up to 95.9% of thermal radiation while blocking the passage
of residual heat to the material beneath (roofs, walls, etc.). Additionally, thanks to low absorptive emissivity, its
surface temperature does not increase, remaining cool throughout the day.
Emissivity is examined in two ways: 1. Adsorptively and 2. Radioactively (in terms of the intensity of heat repulsion
from the surface)
Absorptive emissivity (capacity to take in and retain thermal radiation) is given as a low rate of emission
Radiative emissivity (capacity to dissipate thermal radiation) is given as a high rate of emission
Materials with matte black surfaces have high absorptive emissivity approaching the maximum limit of 1.0 retain a
large volume of radiation. In contrast, bodies with lustrous surfaces such as mirrors or burnished aluminium have low
emissivities around 0.08 and thus retain practically no radiation within themselves. Super Therm® has the incredibly
low absorptive emissivity value of 0.05.
Comparison of absorptive emissivities:
Maximum emissivity value 1.0
matte black surfaces have the highest emissivity values at 0.95
Most building surfaces have high levels of emissivity around 0.90
A mirror-polished surface has an emissivity value of 0.08
Super Therm® has the incredibly low emissivity value of 0.05, thus making it unable to retain almost any heat.
Contrarily Super Therm® has very high (more than 95%, or 0.95 value) infrared radiative emissivity, meaning that it
is extremely effective in shedding even the smallest amount of heat it might absorb.
The result is that even with day-long solar heating and 40-degree temperatures, Super Therm® remains cool on its
surface all day. This unique property differentiates it from ordinary ceramic and reflective coatings.
Thermoinsulation – ability to stop heat transmission
The described thermoreflection, low absorptive emissivity and simultaneous high IR radiative emissivity are the basis
of Super Therm®. Coating’s thermal insulating capabilities. Because the more heat is reflected repelled from the
surface, the less heat will be absorbed and flow to what’s beneath.
Furthermore, the special ceramic also impedes the flow of unreflected solar heat into the surface below. In tests, Super
Therm® coating reduced the BTU conductivity of material from 350 BTU to 3.77 BTU. (BTU – British Thermal
Super Therm®, unique properties, especially its ability to keep surfaces cool even in extreme temperatures, enabled
the coating to pass muster in the California “COOL ROOF” engineering research programme with the highest marks.
Results from the COOL ROOF programme:
Ultraviolet radiation (UV) = 100% blocked
Visible radiation (VIS) = 92.2% blocked
Infrared radiation (IR) = 95.5% blocked
During the 12-year programme, 26 million square feet of roofing material were coated during all seasons and under all
conditions. (You can read more about the COOL ROOF programme on our website in the ROOFING SYSTEMS
The key to success is handling the initial heat load:The HEAT LOAD falling on a surface is key to the need for
insulation and also determines the amount of heat which will be transferred on into the building.
If the initial HEAT LOAD is reduced then the amount of heat transferred inside the building by conduction or
convection is also automatically reduced and this enables the reduction of the thickness of insulating layers, which is
crucial for standard batting or foam insulation.
Standard insulation materials are subject to up to 100% of the initial heat load from the heat source and therefore their
thickness is determined depending on the amount of heat they can retain, and thus retard HEAT TRANSFER into the
building. Super Therm® works mainly on the principle of handling the initial HEAT LOAD arriving at the surface,
and thus the thickness of the insulating layer is not crucial.
Super Therm® has demonstrated that its reflectivity can reduce the initial radiative heat load falling on a surface by
95%. This means that roofs or exterior walls will be burdened by only 5% of the HEAT LOAD which is attempting
to be transferred on into the building. So, after coating, the building will be subject from the start to only the residual
heat load, whose further transfer through the structure by convection or conduction Super Therm® blocks as well.
Standard insulation materials must absorb up to 100% of the HEAT LOAD and therefore depend greatly on their
thickness, because the thickness determines the length of time over which they can prevent heat transfer into the
building by retaining it. Therefore, Super Therm®can’t be compared to classical insulation based on R-value or K-
value, which are calculated based on the thickness of the material.
Super Therm® is designed so that it blocks the initial heat load and then handles only the residual unreflected heat. It
is not designed to absorb the entire heat load as does classical insulation, where accumulated heat gradually leaks into
the building even at night.
Super Therm® is mainly used, therefore, as a peerless, highly-effective means to block direct solar radiation and its
transfer to the building and to prevent the serious 21st-century problems of global warming.
The difference between Super Therm® thermo-insulative coating and thermoreflective coatings:
Research in the roofing materials field has shown that increasing a surface’s solar reflectivity substantially increases
the lifespan of the entire roof covering. Therefore, some asphalt roofing materials manufacturers began furnishing their
products with lustrous metallic foil or painting them with a white or silver reflective coating. This has substantially
protected their products’ surfaces against damage, yet not against heating.
At first glance it appears that the silvery, reflective aluminium paints work as perfect solar reflectors. This is not the
case, though, as flakes of aluminium paint have high reflectivity to the visible solar spectrum yet their ability to hand
infrared emissions is low. They do not repel infrared radiation, but absorb it.
Despite the fact that a mirror-polished silvery surface appears to us as the best heat reflector, in practice such a
surface reflects only visible light rays: a mere 40% in solar radiation and 3% in UV. The remaining 47% is made up of
infrared radiation, which metallic surfaces do not reflect. And as they absorb that radiation, they heat up
tremendously in a short time. Next comes the overheating of the entire roof.
For these reasons, painting a roof as protection against heating with silvery aluminium or ordinary white reflective
coatings is fundamentally ineffective. Only a ceramic coating with ceramic content repelling the whole spectrum of
solar radiation is able to keep a roof surface cool all day. For this, Super Therm® is unmatched!***
The difference is also in the durability of the reflective capabilities
Ordinary reflective coatings lose more than 30% of their reflective properties in the course of 2 years Super Therm®
coating lost only 0.01% of its reflective properties over the course of 3 years (more in the section on TESTING /
Testing the durability of reflective properties).
