How it works
Engineered for real-world performance
RayChill Film combines ultra-high solar reflectivity with mid-infrared emission to achieve sub-ambient cooling with no moving parts and no power draw.
Passive 24/7 Operation
Continuously reflects sunlight and radiates heat into the atmosphere around the clock, with zero energy input required.
30°C Surface Reduction
Achieves up to 30°C surface temperature reduction at noon compared to standard roofing materials like shingles.
100 W/m² Cooling Power
Delivers radiative cooling power equivalent to 100 watts per square metre — entirely passively.
Tape-Format Installation
Easy peel-and-stick tape format enables fast, low-cost installation on new or existing surfaces without specialist labour.
15-Year Lifespan
Engineered for long-term durability with a projected 15-year service life and 1–2 year payback period.
Scalable Manufacturing
Efficient manufacturing process enables cost-efficient large-scale production.
Applications
Works on virtually any surface
RayChill Film's tape-format design makes it compatible with a wide range of surface types and industries. If a surface faces the sky, it can be cooled.
- Commercial rooftops
- Industrial facilities
- Delivery trucks
- Refrigerated vehicles
- Data center roofs
- Supermarkets
