Engineered to interrupt heat
Cool X and Ultra Cool X are advanced exterior coatings designed to manage how heat is absorbed, transmitted, and released at the building surface.
Built for hot climates, concrete facades, and the realities of urban heat.
How the technology works
More than a heat-reflective surface, the coating is engineered to manage the path of heat.
Reduce heat gain
Helps limit how much solar heat is retained at the facade surface.
Slow heat transfer
Helps moderate the rate at which solar heat passes through the coating and into the wall.
Release heat
Helps the surface dissipate absorbed heat more effectively back into the surroundings.
Cooling performance starts at the microstructure
The performance of Cool X comes from its internal coating architecture.
At the microscopic level, the paint film contains engineered Hollow Glass Microspheres, each with a sealed air core. Once dispersed throughout the coating, these microspheres help moderate conductive heat flow through the paint layer, contributing to a measurable difference in how quickly solar energy reaches the substrate beneath.
At the same time, the coating surface is designed to support the release of absorbed heat through thermal emission, helping retained heat dissipate more effectively rather than building up in the wall.
The result is an exterior coating that does more than protect a facade. It functions as an advanced thermal-management layer.
The technology inside Cool X
Cool X incorporates Hollow Glass Microspheres, which are microscopic high-strength glass spheres with sealed air cores. Distributed throughout the paint film, they help manage heat transfer within the coating itself.
Because the hollow core conducts heat less effectively than conventional solid fillers, the coating helps moderate the rate at which solar heat passes from the exposed outer surface towards the underlying substrate.
This is what gives Cool X its heat-managing coating structure.
Why hollow matters
A hollow microsphere creates a less efficient pathway for heat to travel through the paint.
Two mechanisms. One cooler facade.
Reduced heat transfer
The sealed air cores within the Hollow Glass Microspheres help moderate the rate at which heat passes through the coating. While the coating layer is thin, the cumulative effect of thousands of microspheres contributes to a measurable reduction in heat reaching the substrate.
High thermal emittance
The coating surface is also designed to release absorbed heat more effectively through thermal emission, helping the facade shed retained heat rather than allowing it to accumulate over time.
Designed for the realities of urban heat
In dense cities, concrete and masonry buildings often behave like heat reservoirs. They absorb solar energy through the day, store that heat within the building mass, and continue releasing it long after sunset.
This thermal mass effect is one reason urban environments remain warmer into the evening. Surface heating is only part of the issue. Retained heat is the other.
Cool X is designed to help interrupt that cycle by reducing heat transfer into the wall and supporting more effective release of accumulated heat from the facade surface.
Choose the right thermal coating system
The Cool X range is designed to manage solar heat more intelligently at the building surface. Two systems, each engineered for different project requirements.
Three-coat thermal system
Cool X
A heat-managing exterior coating built with Hollow Glass Microsphere technology. Applied as a three-coat system to help moderate heat transfer and support heat dissipation at the facade surface.

One-coat sealer-integrated system
Ultra Cool X
A sealer-integrated one-coat exterior paint designed to reduce material usage, manpower costs, and time on-site. Built for project-scale repaints where efficiency and thermal performance must work together.
- Single-coat application with integrated sealer
- Designed to reduce material and labour costs
- Faster turnaround for large-scale repaints

What this means for your building
Lower heat build-up
Helps reduce heat accumulation at the exposed facade surface.
Reduced thermal loading
Helps moderate the rate of heat transfer into the wall substrate.
Less retained heat
Supports faster release of absorbed heat from the facade.

The science, made simpler
A more intelligent approach to exterior cooling
Cool X and Ultra Cool X are designed for a new generation of building surfaces, where thermal performance, durability, and material science must work together.
