Cool-FX Asia
A roof cooling coating made for climates where the heat is matched by the rain. It reflects solar radiation to keep barns, skylights and commercial buildings cooler, and is built to stay on the roof through the downpours that would wash a lighter coating away.
More wear-resistant by design, it holds its cooling through the wet season and then clears naturally once the weather turns.
Made for wet, tropical heat
The problem with cooling a roof in a monsoon climate is not reflecting the sun. It is keeping the coating on the roof long enough to matter. Frequent, heavy rain strips ordinary seasonal coatings before the hottest months are through.
Cool-FX Asia is formulated to resist that wash-off, so the reflective layer stays intact through repeated downpours and keeps working across the full stretch of hot, wet weather rather than needing to be reapplied after every storm.
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.
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.
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.
What sets Cool-FX Asia apart is staying power. The formula is designed to bond and resist the wash-off that frequent, heavy rain causes, so it does not thin out after the first storms the way a lighter seasonal coating can. It still clears naturally at the end of the season, but through the wet months it stays where it is needed, on the roof and reflecting heat.
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.
It works across the roof types most exposed to sun and rain: galvanised and metal barn roofs, the tar and gravel roofs found on warehouses and offices, and plastic skylights. If you are unsure how your surface will take the coating, our specialists can advise.

Why Cool-FX
A coating matched to the climate
Cooling a building well is a question of fit. A coating that performs in a dry Mediterranean summer is not necessarily the one that lasts through a tropical wet season. Cool-FX Asia exists because those conditions call for a more wear-resistant formula, one tested in the field rather than the lab.
Backed by Lumiforte, it brings proven reflective cooling to the regions where heat and rain arrive together, and where staying power matters as much as reflectivity.
Frequently asked questions
It is formulated for hot, high-rainfall climates, and the main difference is wear resistance. Built to withstand frequent heavy rain, it stays on the roof through the wet season, where a coating made for drier conditions would wash off sooner.
Not readily. Cool-FX Asia is designed to resist the wash-off that repeated downpours cause, so it keeps reflecting heat through the wet months. Like any seasonal coating it clears eventually, but it is built to last through the rain, not disappear after it.
Quickly. Once the coating is on and dry, the roof reflects sunlight straight away, so temperatures start coming down on the next hot day.
On skylights, yes. As well as heat, it reflects part of the incoming light, softening the harsh direct sun that reaches people working below, while still letting daylight through.
