Conductivity
SRI-dependent products don’t mention conductivity because they conduct a lot of heat. Thanks to ICP™ technology, the ultra-low conductivity of NanoTech Cool Roof Coat has no equal in the cool roof market, across all wavelengths and sources.
Reflectivity
Shortwave radiation, including visible and near-infrared light from the sun, bounces off of reflective surfaces back into the atmosphere before converting to heat. It’s a step in the right direction, but its effectiveness is quickly compromised by dirt and soiling.
Emissivity
Longwave infrared radiation is the heat energy emitted by surfaces. Materials with higher emissivity more effectively send the heat they’ve absorbed back into the environment, and in turn cool the surface.
Cool Roof Coat SRI+
While SRI is a valuable metric for evaluating the solar reflectance and thermal emittance of roofing materials, it is flawed as a sole indicator of roof performance due to its limited scope and vulnerability to degradation. Low thermal conductivity, on the other hand, offers consistent and reliable insulation against heat transfer, enhancing energy efficiency and indoor comfort. The combination of high SRI and low thermal conductivity provides a comprehensive approach to roof design, especially in climates where managing solar heat gain is crucial.
Reflectance and Emissivity Are Not Enough
SRI primarily measures solar reflectance and thermal emittance, but does not account for how efficiently heat transfers through the material itself. Thermal conductivity measures how much heat moves past the surface, and the fact that all but one roof coat manufacturer measures and publishes this data tells a story on its own.
Performance Degradation Over Time
SRI is typically measured in a test environment under ideal, just-applied conditions. Roofs, however, are constantly exposed to elements like dust, debris, and biological growth, all of which rapidly reduce reflectance once installed, creating a significant disparity between rated and actual performance.
Limited Focus on Surface Properties
While SRI effectively gauges how a roof reflects solar radiation and emits heat, it neglects other crucial aspects like thermal conductivity, which governs heat transfer into the building.
Diminishing Returns
As SRI values rise above 100, the incremental benefits in terms of heat rejection eventually become negligible. While the highest SRI score may potentially lower surface temperatures (and cooling costs) slightly, competing on SRI alone has become a game of diminishing returns.
Year-Round Thermal Insulation
Low thermal conductivity is a key factor in maintaining energy efficiency by significantly reducing the amount of heat transferred into the building, a consistent need in hot climates.
Unaffected by External Surface Conditions
Unlike SRI-dependent products, thermal conductivity continues to work below the surface even as dirt accumulation and soiling compromise conventional heat rejection mechanisms on the surface.
Complementary to High SRI
As high SRI reduces solar heat gain in hot climates, low thermal conductivity minimizes heat ingress to provide energy efficiency on as well as below the surface.
Stability in Indoor Environments
Roof surfaces with low thermal conductivity maintain more stable indoor temperatures, reducing the load on air conditioning systems, improving occupant comfort, and protecting stored goods.
Integral to Energy Efficient Building Design
Incorporating low thermal conductivity into energy modeling for hot climates is crucial for achieving optimal energy performance, because SRI alone is no longer enough.
SRI+ Explained
Reflectivity
Imagine the outer surface of the cooler is coated with a highly reflective material, similar to a high SRI roof coating. This reflective surface is like the cooler’s ability to reflect sunlight away, preventing the ice inside from melting quickly due to solar radiation. Just as a reflective roof reduces heat absorption, the cooler’s reflective surface keeps its contents cooler under the sun.
Emissivity
The cooler’s material is designed to emit any absorbed heat, much like a roof with high thermal emittance. Even if the cooler absorbs some heat from the surrounding environment, its ability to emit this heat helps in maintaining a lower internal temperature, just as a high-emissivity roof coating releases absorbed heat to keep the building cooler.
Heat Resistance
The insulation of the cooler, which prevents the transfer of heat from the outside environment to the ice inside, represents low thermal conductivity. This insulation is crucial for keeping the contents cold, similar to how low thermal conductivity in a roof coating minimizes heat transfer into a building, maintaining cooler indoor temperatures.
SRI +
Reflectivity and emissivity in cool roof coatings effectively reduce heat absorption and emission, but adding low thermal conductivity brings a transformative third dimension. While reflectivity minimizes solar heat gain by bouncing back sunlight, and emissivity helps in releasing absorbed heat, they primarily address the solar radiation aspect. The integration of low thermal conductivity adds critical insulation and heat resistance. This means not only is less heat absorbed from the sun, but any heat that does reach the roof is significantly impeded from entering the building. This combination offers a more comprehensive approach to thermal management, significantly enhancing overall energy efficiency and indoor comfort, and represents a substantial leap forward in cool roof technology.
Cool Roof and Coating Properties
Competition in roof coatings is stale and two-dimensional, limited to improvements in whiteness that only produce diminishing returns. Reflectivity is not only a scientific dead end because dirt quickly undermines the meager heat mitigation it provides. In the real world, the sun delivers light and heat on, across, and through surface coatings, and moisture, hail, and wind are constantly at work to undermine longevity. It’s time to fight heat in three dimensions with a tough cool roof coating that also works below the surface.
