You’re not the only one sweltering at home.
The Urban Heating Island (UHI) effect is what’s causing cities to become hotter than surrounding areas. In Singapore, the average difference can sometimes be as high as 7°C.
Worse still, our reliance on air-conditioning units and cooling systems exacerbates the problem by further contributing to global warming, meaning that these can only be temporary relief from the heat.
Clearcool is designed to limit the transmission of solar radiation. Imbued with ceramic nanoparticles that are aggressive in absorbing solar transmission and limiting heat energy from entering our homes.
Not only that, Clearcool’s ceramic makeup means that it will never change colors or fade even after prolonged exposure to direct sunlight. Unlike dye-based window films that fade and discolor over time, ceramic is a highly durable and color resistant material that guarantees clear windows for years to come.
The three main components in sunlight are infra-red (IR), visible light, and ultra-violet (UV). IR Radiation accounts for the majority, making up 54.3% of solar radiation, while visible light and UV make up the remaining 38.9% and 6.8%.
While it is common knowledge that no solar films can completely block out heat, most films can block out UV rays since it has the shortest wavelength amongst the three. However, Clearcool sets itself apart from the rest through its ability to block out 90% of the full range IR ray spectrum - 900 to 2500 nanometers.
Heat and light come hand-in-hand, often resulting in a conundrum where one has to compromise on natural light for cooler indoor spaces (and vice versa).
But Clearcool80 overcomes all that. Allowing 80% of light to pass through while retaining high heat blockage, Clearcool80 assures you of both brighter indoor spaces and thermal comfort.
In an experiment conducted by the Building Construction Authority, two adjacent west-facing rooms had double-glazed windows installed, with one coated with Clearcool. Both rooms had their internal air-conditioning temperature stabilised at 24ºC and readings taken between 9am to 6pm.
The room coated in solar films experienced a reduction in solar radiation transmittance that translated to 9.47% in energy savings.
Using the Heat Transfer Formula and the Affinity Law, the results were then extrapolated. We were then able to deduce that in a building where a variable fan coil was used instead, as much as 14.5% cooling energy savings can be achieved.
This is how we cool your home without compromising on our carbon footprint.

“Climate change is making cities increasingly warmer. Living here in Singapore, we can see very clearly global warming’s impact on our temperatures and the resultant demand for extensive cooling energy to reach indoor thermal comfort. Air conditioning alone makes up 40 - 50% of a building’s total energy consumption. We believe that there should be better cooling solutions that lower our energy consumption and are cost-effective, and that’s what inspired us to design Clearcool solar films.”
