CSIRO-Tested Performance: Why EnduRE30C Sets a New Benchmark for Cool Roof Coatings in Australia
When it comes to thermal performance, claims alone aren’t enough—especially in Australia, where architects, engineers, councils, and asset owners expect independent, local validation.
That’s why EnduRE30C Radiative Cooling Coatings were independently tested by CSIRO, Australia’s national science agency, using internationally recognised ASTM standards. The results confirm what makes EnduRE30C different: high-end thermal performance that can outperform most conventional cool roof coatings—and it’s not limited to white-only finishes.
Independently Tested by CSIRO
CSIRO conducted Solar Reflectance Index (SRI) testing on EnduRE30C Gen 5 and Gen 7 coatings in accordance with:
- ASTM E903 — Solar Reflectance
- ASTM E408 — Total Hemispherical Thermal Emittance
- ASTM E1980 — Solar Reflectance Index (SRI)
These tests measure how effectively a coating:
- Reflects incoming solar energy
- Emits absorbed heat
- Reduces surface temperature under sun exposure
This isn’t modelling, simulations, or lab-only overseas claims. It’s independent testing conducted in Australia.
What the Results Show
CSIRO testing confirmed EnduRE30C delivers:
- Very high solar reflectance (≈93%)
- High thermal emittance (≈0.87)
- Solar Reflectance Index (SRI) values up to ~120
For context, an SRI above 100 is considered top-tier cool roof performance. Many standard “cool roof” paints sit significantly lower, even when they are bright white.
These results validate EnduRE30C as a true radiative cooling system, not just a reflective surface.
Why SRI Matters More Than “Reflectivity”
Many products advertise reflectivity alone. But reflectivity only tells part of the story.
SRI combines both solar reflectance and thermal emittance, giving a more accurate picture of how hot a roof surface will become in the sun. That’s why SRI is commonly referenced by:
- Architects and specifiers
- Green building frameworks
- Councils and infrastructure projects
With SRI values approaching 120, EnduRE30C clearly sits in a performance class that can outbeat most competing coatings in the market.
Developed in China—Validated in Australia
EnduRE30C was developed using advanced rare earth functional material technology in China—one of the world’s most advanced hubs for rare earth research and production.
But performance matters more than origin.
By submitting EnduRE30C to CSIRO for independent testing, Easyto Thermal Solution Australia ensures the product:
- Meets Australian expectations for transparency and credibility
- Is validated under local laboratory conditions
- Can be confidently specified for Australian climates and projects
This approach bridges global innovation with local authority and trust.
A Key Advantage Most Competitors Can’t Match: Colour Flexibility
One of the biggest limitations of traditional cool roof coatings is simple: they rely on being white.
Darker colours typically absorb more heat, forcing designers and asset owners to choose between aesthetics and thermal performance.
EnduRE30C changes that. Thanks to its rare earth–driven radiative cooling mechanism, EnduRE30C can maintain strong thermal performance even when coloured. This enables:
- Greater design freedom
- Better visual integration for buildings and infrastructure
- More practical retrofit options where white is not acceptable
In other words: thermal insulation no longer has to come at the expense of appearance.
Beyond Reflection: Radiative Cooling by Design
Unlike conventional reflective paints that primarily bounce sunlight away, EnduRE30C is engineered to:
- Reflect a large portion of incoming solar energy
- Support passive heat release through radiative emission mechanisms
Note: Radiative cooling power and atmospheric window emissivity are based on material design characteristics and internal testing. CSIRO testing validates overall solar reflectance, thermal emittance, and SRI performance.
Confidence for Specifiers, Councils, and Asset Owners
Independent CSIRO testing gives decision-makers confidence that:
- Performance metrics are verifiable
- Testing aligns with recognised ASTM standards
- The product meets expectations for professional specification in Australia
For projects where long-term thermal performance, energy reduction, and durability matter, EnduRE30C provides data-backed assurance—not just promises.
Setting a New Standard for Cool Roof Coatings
The CSIRO report confirms what makes EnduRE30C different:
- Independently tested in Australia (CSIRO)
- Top-tier SRI performance
- High solar reflectance + high thermal emittance
- Colour flexibility without being restricted to “white-only”
In a market crowded with “cool roof” claims, EnduRE30C stands out because its performance is measured, validated, and proven.
