THE PRODUCT, EXPLAINED
A film on the surface. An effect on heat.
Start with one example: Polar 90 film. Three steps to understand what is applied and how it works.

Concept diagram · thickness exaggerated for clarity
A thin material. An active surface.
Polar 90 is a white self-adhesive film supplied in rolls. It covers large exposed surfaces: roofs, cladding, tanks or silos.
220–240 µmPolar 90 film thickness
It covers the existing substrate.
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.
52 cm × 100 mPolar 90 roll size
Less sunlight absorbed. More heat released.
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.

What it means for businesses
- Maintain business continuity during hot weather.
- Protect staff, stocks and sensitive equipment.
- Reduce peak power demand and air-conditioning bills.
- Adapt existing buildings with minimal intervention.
Two complementary approaches
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.
01 / THE PRINCIPLE
Two physical processes. One cooler surface.
The material reflects some sunlight and emits heat towards the sky. This is passive radiative cooling, requiring no active energy input for the process.
THE SKY AS A HEAT EXCHANGER
SPACEATMOSPHERE
0.3–2.5 µmSOLAR RADIATION
Conceptual visualisation, not to scale. Results depend on the substrate, climate and application conditions.
Emit heat.
Every warm surface emits energy as infrared radiation. The material promotes this thermal emission.
Open a window
to space.
Within the 8–13 µm atmospheric window, some radiation escapes into space, carrying heat away.
Cool, naturally.
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.
Understanding the process and performance limitations
01 — Understanding
What is radiative cooling?
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.
1 · Reflect
solar radiation to limit surface heat gain.
2 · Emit
high levels of infrared radiation within the 8–13 µm atmospheric window.
3 · Release
some heat into space, without any active energy input.
* 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. The radiative properties of SolCold products are an exception: they have been measured by a third-party laboratory.

APPLICATION AREASSchools • shopping centres • offices • hospitals • airports • data centres • logistics warehouses
Other airports: Haneda, Hangzhou and Xiamen
Case studies — transport
Haneda, Hangzhou, Xiamen: different configurations, one objective
Tokyo — Japan
Haneda airport
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.
Hangzhou — China
International airport
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.
Xiamen — China
Gaoqi airport
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.
Applications
Why terminals are suitable
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.
Glazing: glazed roofs, façades and domes
Case studies — glazing
Glazed roofs, façades and domes: managing radiation before it heats the interior
Glazed roof
Daily peak reduced by 4.7 °C
During a test period with air conditioning set to 26 °C, the average daily peak temperature fell by 4.7 °C after film application.
Glazed façade
Significantly improved perceived comfort
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.
Glazed dome
Reduced radiant temperature
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 %.
The right film depends on the glazing
Light transmission, colour, solar rejection, installation position and any Low-E coating must be checked before specifying a film.
Industry: tanks, sensitive storage warehouses and logistics roofs
Case studies — industry
Tanks, reservoirs, warehouses: limiting product and structure temperatures
Oil storage tanks
Reducing wall and contents temperatures can lower internal pressure, limit evaporation losses and improve operational safety during hot weather.
Temperature-sensitive warehouses
Radiative solutions are particularly suited to buildings where preservation depends on stable temperatures: food, beverages, pharmaceuticals or sensitive materials.
Logistics roofs
Across large roof areas, every degree of heat gain avoided at the envelope helps reduce the building's overall thermal load.
Silos and storage
Highly exposed roofs and curved walls can be treated with film or coating, depending on the substrate and geometry.

Comparison of the two films — LNE & TESA SE measured data
| Property | Polar 90 | Glacier 110 | ASTM E1980 reference white |
|---|---|---|---|
| Solar reflectance (LNE) | 87.7 % | 89.5 % | 80 % |
| Emittance at 25 °C (LNE) | 85.5 % | 83.4 % | 90 % |
| SRI LNE (convection 12 W/m²K) | 110.5 | 112.8 | 100 |
| TESA SRI (same conditions) | 114 | 121 | 100 |
| Surface temperature (TESA) | 39.5 °C | 36.7 °C | 44.6 °C |
| Difference / air temperature | +2.6 K | −0.2 K | +7.7 K |
| Reflected solar energy | 877 W/m² | 895 W/m² | 800 W/m² |
Specification rationale. When dealing with an engineering consultant, insurer or public-sector client, the SRI measured by two independent laboratories (LNE and TESA SE) is the most robust data in the catalogue: standardised, comparable and independently verified. By contrast, the FR, T, Textile and Coatings ranges rely on supplier data, to be confirmed by testing if the contract requires it.
Economics & methodology
ROI is calculated from the building, not the product alone
A rollout decision relies on a monitored pilot, not just a product data sheet.
1 · Baseline
12 months of consumption and hourly profiles for the existing building.
2 · Model
Area, insulation, weather, setpoints and building use.
3 · Pilot
An on-site treated area and a monitored control area.
4 · Decision
Normalised savings and full costs validated before wider deployment.
Simple payback = total investment ÷ net annual savings. Include preparation, installation, downtime, maintenance, cleaning, financing and any incentives.
Illustrative payback for 1,000 m² at €45/m² excl. VAT (reference investment: €45,000 excl. VAT)
4.5 yearsconservative scenario — €10k/year savings
3.0 yearscentral scenario — €15k/year savings
2.25 yearshigh-savings scenario — €20k/year savings
0.5 to 2.9 yearsreported payback in real field cases (silos, server rooms)
Illustrative scenarios to be replaced with the site's invoices, measurements and installation conditions.
Proposal: validate the decision with a monitored pilot
Recommended scope
- A representative area and a comparable control area.
- 4 to 8 weeks during a hot period.
- Surface / air temperatures, weather and cooling consumption.
- A normalised before / after report with a deployment decision.
Deliverables
- Substrate assessment.
- Installation and safety plan.
- Instrumentation and monitoring.
- Energy assessment and budget for wider deployment.
A pilot turns a product promise into site-specific evidence
We offer an assessment, quotation and pilot plan tailored to your building.
The €45,000 excl. VAT represents an illustrative supply cost for 1,000 m² of Polar 90. For your project, the calculation must include the full implementation cost and measured savings. Payback periods of 0.5 to 2.9 years relate to specific cases, with no guarantee of identical results.
