CoolBond® is a water based, acrylic, high-build membrane with a CTC ‘cellutec’ nano powder additive which significantly reduces heat transfer. Keeping cool indoors when it is hot outdoors is a problem. The sun beating down on buildings causes indoor temperatures to rise to uncomfortable levels. Air conditioning gives us relief but the electricity costs to run it can be high.

CoolBond® is an Australian technology. It is a heat radiant barrier coating. The water based acrylic membrane with CTC when sprayed on any surface to a thickness of 250 to 300 microns (DFT), significantly reduces the heat inside the building. This energy saving coating is extremely lightweight and pliable. Therefore it expands and contracts with the surface to which it is applied.

Traditional Insulation slows down the rate of heat transfer, however after some time, the internal temperature rises above the external ambient temperature. CoolBond® not only blocks heat transfer at source i.e. outside the structure, but also allows heat (normally trapped inside by bulk insulation) to escape more readily.

As the building cools with the external ambient temperature, so does the interior temperature. CoolBond® is able to keep the building closer to shade temperatures. CoolBond® is also more economical to install compared to traditional insulation, as it does not involve lifting the roof or removing the ceiling. As CoolBond® is applied externally, on top of the roof or external walls, your business will not be interrupted during application.
Concrete roof & wall – Stabilises temperature, reduces crack formation and waterproofs
Roof & Wall – Blocks heat transfer. Reduces power consumption and increases comfort levels
Air Conditioning – Reduces heat load on Systems – Use on cooling towers, chillers, and a/c units and especially all air ducting exposed to the sun
Water Tanks and pipes – Will reduce heat stress on all structures containing water or other liquids and keep the contents cooler by by 5°C-10°C plus
Petroleum tanks – Reduces fuel evaporation
Electrical Power boxes – Less heat load on Sensitive Equipment. Stop power outages due to blown fuses in high temperatures.

Advantages over standard insulation materials

  • Hides masonry cracks
  • Reduces energy costs
  • Waterproofs and insulates at the same time​
  • Non Toxic
  • Extremely flexible
  • Non Flammable
  • Impervious to salt spray and airborne pollution
  •  Protects metal from extreme weather conditions
  • Easy to apply
  • Environmentally friendly

Note: CoolBond® shouldn’t be confused with or compared to bulk insulation on R/K values because mass type insulation retards heat flow whereas selective surface impedes heat flow.


Properly specified and applied, CoolBond® treated surfaces do not require maintenance over their life for 10 years.
