Radiative cooling - passive cooling · Low-E Transmissive energy-saving window curtain
01Conventional heat-rejection films stop at “blocking” solar heat — the heat absorbed by the film itself slowly warms the film body and then conducts to both sides of the glass, indoors and out.
02The radiative-cooling film in the Huiyuan range is different: across the 8–13μm mid-to-far infrared band (the “atmospheric window”, through which heat escapes directly to outer space) it continuously radiates the absorbed heat away, achieving “passive cooling” — no electricity and no moving parts.
0350.4% infrared reflectance, 99%+ UV blocking rate and 5% visible-light transmittance. The blue film transmits light evenly — ideal for projects seeking cutting-edge energy-saving technology and a distinctive visual identity.
