Stop the heat at the source. Our sheets reflect solar thermal rays to reduce surface temperatures by approximately 15°C (27°F) while blocking 99% of harmful UV rays.

In the face of intensifying heatwaves, blocking near-infrared heat from windows and AC units has become an essential strategy for energy efficiency. F+COOL reflects near-infrared light, which accounts for about 50% of solar energy, to drastically suppress surface heat. Unlike blackout options, it maintains a bright interior while providing a powerful thermal barrier. Installation is effortless: simply apply the sheet wherever needed. No painting or drying time required. By stabilizing indoor temperatures, it boosts cooling efficiency, lowers electricity costs, and reduces CO2 emissions. Certified under JIS L 1951 and 1952 (UPF50+).

Heat-Shielding Performance: Empirical Testing Using Artificial Solar Light.

Our performance tests, conducted in accordance with JIS L 1951 standards, visualize the dramatic temperature difference between surfaces protected by F+COOL and those left exposed to near-infrared rays.
By placing high-precision thermometers at the base of the test environment, we confirmed a significant reduction in surface temperature, proving the sheet’s superior thermal barrier capabilities. In addition to heat management, F+COOL is certified by independent agencies for maximum sun protection:
UPF 50+ (Ultraviolet Protection Factor) and a 99% UV rejection rate.

Proven Performance and Versatile Business Applications.

Our testing confirms that F+COOL’s reflective properties prevent the material itself from absorbing heat, keeping the surface remarkably cool.
Please note that this product is specifically engineered to target near-infrared rays from direct sunlight; it is not intended for shaded areas or far-infrared heat sources like industrial boilers. A key advantage for commercial use is its light transmission.
By selectively reflecting heat while allowing visible light to pass through, F+COOL ensures interiors remain bright and inviting. It is the perfect balance of superior heat shielding and natural illumination.
Maintains excellent natural light; spaces remain bright after installation.

Lighting Performance & Thermal Suppressing Verification.

Our field tests demonstrate a dramatic suppression of surface heat compared to untreated areas. This high-performance reflectivity provides critical relief in environments where extreme heat is a major operational challenge:
[Outdoor & Leisure] Heat mitigation for beaches, artificial turf, sports fields, and stadium seating.
[Urban Infrastructure] Reducing heat accumulation in concrete, public benches, and vehicle hoods.
[Buildings & Facilities] Significant energy savings for factories and residences via windows and sunshades.
Whether applied as a wrap or a cover, F+COOL shuts out the heat source anywhere you need it.
Note: A flame-retardant version is currently under development to meet high market demand.
