Cool-FX Classic

A temporary, water-based coating that keeps buildings cooler through summer by reflecting solar radiation before it reaches the roof. 

It lowers indoor temperatures in barns, skylights and commercial buildings, improving working conditions and reducing the load on air conditioning. Applied when the heat arrives, it wears away naturally once the season ends, leaving no lasting effect on the roof.

Energy savings

Cooler buildings all summer 

Dark and uninsulated roofs absorb solar energy through the day and pass that heat into the space below. In barns, workshops and commercial buildings without air conditioning, this pushes indoor temperatures to levels that affect comfort, productivity and, in livestock housing, animal health.

Cool-FX Classic reflects a large share of solar radiation before it is absorbed, so less heat reaches the roof and the interior stays cooler through the warmest part of the day.

7.3°C

Cooler inside

In the Turkey trial, with no cooling running at the peak of the afternoon, the coated barn measured 7.3°C cooler inside than the uncoated control. That head start eases heat stress and reduces how hard the cooling system must work.   

14.7°C

Cooler surface

During application, the coated roof measured 34.5°C against 49.2°C on the uncoated roof, a surface reduction of 14.7°C. Lower surface temperatures ease thermal stress on the roof and slow the transfer of heat into the building.

12%

Lower energy use

Across the full 42-day cycle, the uncoated control barn used 12% more electricity for cooling than the coated barn. For operators running fans and cooling pads through summer, that is a direct and repeatable saving.

Application & coverage

Mix with clean water and spray on in a single coat, with no priming or surface prep. A 20 kg bucket covers around 200 m² of roof surface. Apply in a dry window so the coating can bond before the next rain, and on sloping roofs use slightly less water so it stays put.

Livestock productivity

Cooler, more stable barn conditions do more than improve animal welfare. In a controlled poultry trial in Ankara, the coated barn returned a better feed conversion ratio than the uncoated control, 1.36 against 1.42, meaning the birds gained more weight from the same feed. Meat yield was around 3% higher, and animal losses over the 42-day cycle fell by 21%. For producers, that connects a cooler roof directly to healthier flocks and stronger output. 

Suitable surfaces
The coating suits galvanised and metal barn roofs, the tar and gravel roofs common on commercial buildings and offices, and plastic skylights.

Why Cool-FX

Keeping buildings cooler across Europe 

Reducing heat build-up takes more than a coating. It takes real understanding of how your building works and what a hot summer costs you. Cool-FX supports facility managers, industrial operators and farmers who need results they can measure.

Our reflective coatings lower indoor temperatures by up to 3.5°C and cut roof surface temperatures sharply. In one poultry trial, coated barns used 12% less electricity for cooling across the cycle.

Frequently asked questions

Which roof types can Cool-FX Classic be applied to?

Cool-FX Classic is designed for barn roofs in galvanised or metal, tar and gravel roofs on commercial buildings and offices, and plastic skylights. Coverage and dilution depend on how smooth or porous the surface is.

How long does the coating last?

One application protects through the warm season, typically 3 to 5 months from May to September. Rain, wind and UV gradually wear the coating away, and the roof returns to its original colour without any manual removal.

Does the coating affect heating costs in winter?

No. Because Cool-FX Classic wears away by the end of summer, the roof absorbs sunlight normally again in winter. This avoids the winter heating penalty that permanent white coatings can cause in cooler climates.

Is Cool-FX Classic solvent-free?

Yes. Cool-FX Classic is a water-based, solvent-free coating that mixes with clean water for application.
