Most people still believe insulation must be thick to work.
Batts. Boards. Foam. Layers of material measured in tens or hundreds of millimetres.
Then along comes a coating that cures at 0.25 mm dry film thickness and claims real energy reduction.
The reaction is predictable.
“Too thin to matter.”
That assumption is where the mistake starts.
Traditional insulation works primarily by slowing conductive heat flow. That is where R-values come from. The thicker the material, the higher the resistance.
But solar heat gain in hot climates is not just a conduction problem.
It starts as radiation.
If that radiation is absorbed at the surface, the material heats up.
Once the surface heats up, conduction takes over.
Now the heat is inside the structure.
Most systems focus on slowing the heat once it has already entered the material.
That is reactive design.
Super Therm® was developed from multi-ceramic compound research in collaboration with NASA engineers in the early 1990s.
It was not designed to trap air.
It was designed to control radiation before heat load forms.
At only 0.25 mm dry film thickness, it works because of surface physics, not mass.
Its performance is driven by:
This combination forms what can be described as a Heat Blocking Factor. Not one property. A system of properties working together.
The coating does not absorb and store heat like metal, concrete or dark paint.
It reflects, rejects and re-emits energy before bulk temperature rise occurs.
That changes everything.
Thickness matters when you are fighting conduction alone.
But if you stop the majority of radiation at the surface, you reduce the heat energy available to conduct in the first place.
It is cause and effect.
Surface heat behaviour determines load behaviour.
If the surface does not store heat, the interior does not fight heat.
Field trials have repeatedly demonstrated this. For example, government cool roof testing in Adelaide recorded internal temperatures up to 6°C below ambient after application.
That is not theory. That is measured performance.
Because Super Therm® blocks radiation without consuming electricity, the energy reduction is permanent once applied.
There is no system to power.
No moving parts.
No parasitic load.
Buildings coated externally reduce HVAC demand because the envelope is no longer acting like a heat battery.
In many cases, energy reductions of 40% to 50% have been calculated when the entire envelope is coated.
And it achieves this at 250 microns dry film thickness.
That is the leverage point.
Scepticism around thin coatings usually comes from comparing them to bulk insulation using only conductivity values.
That comparison ignores:
In hot climate design, those factors dominate daytime performance.
A thin coating that controls radiation can outperform thick insulation that simply slows conduction after absorption has already occurred.
Different mechanism. Different outcome.
Any structure where the envelope becomes a heat source under solar load.
If the surface is controlled, the load drops.
If the load drops, energy demand drops.
The win is not magic.
It is physics applied at the correct point in the heat transfer chain.
Instead of managing heat after it enters the structure, Super Therm® manages it before it becomes a problem.
0.25 mm.
Multi-ceramic structure.
Surface heat control.
Small thickness.
Large impact.
That is leverage.
If the industry continues to judge performance only by thickness, it will keep solving yesterday’s problem.
Surface physics is where the real gains are made.
