Start with one example: Polar 90 film. Three steps to understand what is applied and how it works.
Concept diagram · thickness exaggerated for clarity
Polar 90 is a white self-adhesive film supplied in rolls. It covers large exposed surfaces: roofs, cladding, tanks or silos.
The film adheres to a compatible surface. Here it is shown on a profiled steel roof. Substrate suitability, preparation and application conditions must be validated for each project.
The film reflects a large proportion of solar radiation and emits heat as infrared radiation towards the sky. This process works passively, without electrical power.
A different substrate? Cooleco also offers window films, coatings and textiles.
Find the right productPolar 90 specificationsPolar 90: reflectance and emittance measured by LNE, August 2026; surface temperatures calculated using TESA SE data. Performance depends on operating conditions; detailed results and conditions are provided in the product specifications.
1 · Reduce heat gain — treat the envelope before heat enters the building.
2 · Optimise equipment — sizing, control and efficiency of cooling systems.
Peak cooling demand coincides with the hours when the electricity grid is under the greatest pressure.
Context figures published by Cooleco and included in the September 2026 catalogue.
The material reflects some sunlight and emits heat towards the sky. This is passive radiative cooling, requiring no active energy input for the process.
Conceptual visualisation, not to scale. Results depend on the substrate, climate and application conditions.
Before cooling, limit heat gain. High solar reflectance reduces the energy absorbed by the surface.
Every warm surface emits energy as infrared radiation. The material promotes this thermal emission.
Within the 8–13 µm atmospheric window, some radiation escapes into space, carrying heat away.
Reflection and emission reduce the thermal load. Polar 90 example: 45.8 → 39.5 °C compared with white-painted sheet metal. ASTM E1980 calculation: air 36.9 °C, sky 26.9 °C, solar irradiance 1,000 W/m², convection 12 W/m²K, TESA SE data.
Passive radiative cooling uses a natural phenomenon: every warm surface emits energy as infrared radiation. When this radiation escapes into space through the 8–13 µm atmospheric window, the surface releases some of its heat. Cooleco solutions combine high solar reflectance with high infrared emittance to limit heat gain and reduce the thermal load of buildings.

* Performance varies with climate, geometry, orientation, substrate, insulation level and building use. Unless explicitly stated otherwise, the figures in this catalogue come from tests and reference cases supplied by manufacturers and must be confirmed by a project-specific study.

On a treated boarding bridge, the documentation reports a roof temperature difference of 25.3 °C, with a surface maintained up to 6.3 °C below ambient air temperature. The interior ceiling also showed a difference of around 8.2 °C.
Large-scale application on a metal roof. Preliminary data indicate a reduction in the temperature of the inner surface of up to 21.7 °C.
A project combining reflective and transparent films on a boarding bridge. The documentation reports a reduction in surface temperature of up to 32.3 °C and a reduction in conditioned air temperature of around 4 °C.
Metal roofs, glazed façades, boarding bridges and technical areas often experience high solar loads. Combining opaque and transparent films allows the entire envelope to be treated while preserving the use of glazing.
During a test period with air conditioning set to 26 °C, the average daily peak temperature fell by 4.7 °C after film application.
A monitored shopping centre recorded up to −11.5 °C in black globe temperature and −3.4 °C in air temperature. The estimated percentage of dissatisfied occupants fell from 100% to 16% in the study.
With ambient air at 35 °C and simulated air conditioning at 26 °C: mean radiant temperature 33.7 → 26.4 °C, standard effective temperature 29.5 → 25.8 °C, PPD 28 → 5 %.
Light transmission, colour, solar rejection, installation position and any Low-E coating must be checked before specifying a film.
Reducing wall and contents temperatures can lower internal pressure, limit evaporation losses and improve operational safety during hot weather.
Radiative solutions are particularly suited to buildings where preservation depends on stable temperatures: food, beverages, pharmaceuticals or sensitive materials.
Across large roof areas, every degree of heat gain avoided at the envelope helps reduce the building's overall thermal load.
Highly exposed roofs and curved walls can be treated with film or coating, depending on the substrate and geometry.
