Heat does not move one way. It transfers through radiation, conduction and convection.
Most “cool roof” products focus on one or two levers. Usually reflectivity and some have emissivity. Make it white. Bounce sunlight. Done.
That is only partial surface temperature management.
It is not full heat load control.
If you want to stop energy entering a building envelope, you need to manage the entire behaviour of heat at the surface. That means how radiation is reflected, how infrared is emitted, how fast energy diffuses, and how little is conducted through the film.
That is where the 4-multi-ceramic structure changes the game.
Independent testing confirms that Super Therm® blocks an average of 96.1% of total solar heat load.
That total load includes:
Infrared is the real problem. It carries the bulk of heat energy.
Standard coatings reflect visible light well. They often fail in the near infrared spectrum.
Super Therm® reflects 97% of UV and blocks up to 99% of infrared heat. That is not marketing. That is measured performance under ASTM test methods.
But reflectivity alone does not explain the result.
The formula combines four specific ceramic compounds engineered to perform different thermophysical roles.
Reduces incoming radiation at the surface. This lowers immediate surface heat load based on colour.
High emissivity allows absorbed energy to re-radiate outward efficiently instead of building up in the film.
Thermal diffusivity controls how fast heat moves through a material.
Low diffusivity slows heat penetration dramatically. This is critical during peak solar load.
Diffusivity is not the same as conductivity. Conductivity measures how easily heat flows under steady state. Diffusivity measures how quickly temperature changes move through the material. In real sun exposure, transient behaviour matters more.
Reduces heat transfer through the dry film thickness of 0.25 mm. At just 250 microns, performance depends on structure, not bulk mass, no multiple coats, just absolutely optimised performance.
Performance is not one number. It is a system response.
The coating’s effectiveness comes from the combination of:
Together, these properties prevent heat load from building, penetrating or storing in the surface.
This is surface heat behaviour control, not just colour.
Bulk insulation works by thickness and trapped air.
Super Therm® works by thermophysical behaviour.
No electricity. No mechanical systems. No absorption cycle.
Just prevention.
Many coatings try to compensate for weak thermal behaviour by adding more material. Thicker acrylic films. Heavier elastomerics. More millage to slow conduction.
That approach relies on resistance through bulk just like traditional insulation.
The problem is simple. If the coating absorbs heat, thickness only delays the inevitable. The energy still enters the substrate.
Super Therm® performs at optimal level at 0.25 mm dry film thickness because it is engineered to block, emit and resist heat at the surface. It does not need to be built up in heavy layers to achieve performance. In fact, beyond its designed thickness, performance does not improve. The structure is already doing the work.
Micro-thin, full-envelope application outperforms thicker decorative or elastomeric paints and old school insulation because the behaviour is controlled at the radiation stage, not after heat has already entered the system.
Government trials and real-world applications show internal temperature reductions and measurable HVAC load decreases when the coating is applied to the exterior envelope.
Surface temperature drop is one thing.
Reduced internal heat gain is what matters.
There is a huge difference.
Most products chase reflectance numbers.
The 4-multi-ceramic structure manages radiation, emission, diffusion and conduction together.
That is why it blocks 96.1% of total solar heat load.
Not because it is white. Because it is engineered.
If you want to reduce heat load properly, you start at the surface. Not in the ceiling cavity.
