Coolcote is a liquid ceramic based elastomeric membrane that, when applied to your roof, greatly reduces the amount of heat transferred through it.

When solar radiation strikes an uncoated roof, it is converted into long wave Infra Red radiation.  This radiated energy passes down through the roof, and is absorbed by concrete, steel, bricks, machinery and people inside the building. The internal temperature then continually rises throughout the day.

The graph to the right indicates metal temperatures for an uncoated and coated roof. Wind or cloud can affect results.

METAL ROOF UNCOATED METAL ROOF COATED WITH COOLCOTE™ THE HOTTER IT GETS THE BETTER IT WORKS!

HOW DOES COOLCOTE™ WORK?

CoolCote™ is a brilliant white colour that reflects solar radiation (which represents about 60% of the total energy striking a building's roof), and prevents it from transferring its energy as heat. About 80% of the solar radiation is reflected back into the sky after striking a surface coated with CoolCote™.

The other 40% of thermal energy striking a building's roof is in the form of Infra Red radiation. The specially selected minerals in CoolCote™ reflect and emit around 90% of this energy back into the atmosphere. An untreated galvanised roof will emit only about 40% of the Infra Red radiation.

Visible Radiation in the Day UNCOATED ROOF COATED ROOF An average uncoated roof reflects about 20% of the available solar radiation and absorbs about 80%. This energy is then radiated into the building below. Circulating air absorbs this heat from the underside of the  roof and increases the overall inside temperature. A coated roof reflects about 80% of the solar radiation and absorbs only 20%. The ceramic beads also increase the insulation effect and slow any transfer of heat energy down through the roof.

Infra-Red Radiation in the Day UNCOATED ROOF COATED ROOF An uncoated roof emits about 40% of the Infra Red radiation that strikes it. Most of this energy is absorbed and transferred into the building below. A coated roof reflects and emits about 90% of the Infra Red radiation striking it. The ceramic beads in CoolCote™ also act as an insulation barrier - greatly reducing the amount of heat being transferred to the building below.

Coolcote™continues to work at night... UNCOATED ROOF COATED ROOF At night hot air in a building heats the roof, but being a poor emitter of energy, it only releases it back to the cooler outside air at a very slow rate. The building can still be very hot the next morning. Because CoolCote™ is a very efficient emitter of energy any trapped heat is quickly absorbed through the roof and emitted back into the cooler night air.

PROVEN TECHNOLOGY

CoolCote™ also utilises technology developed for NASA's Shuttle programme. The product contains tiny ceramic spheres, around 100 microns in diameter. Each of these contain a perfect vacuum, creating a coating that forms an excellent insulation and sound barrier - just like billions of tiny thermos flasks.

CoolCote's™ ability to emit heat is particularly useful at night. Any built-up energy in a building is absorbed back through the roof, allowing the building to cool rapidly. Traditional roof materials retain heat in a building throughout the night because of their low emittance values.

Over a whole day up to 50% of the solar heat load is prevented from entering a building's coated roof.

During hot weather, internal building temperatures can be reduced by over 15°C after the application of CoolCote™

The ceramic particles used in CoolCote™ are similar to those used in the Space Shuttle tiles. A thin coating of these particles will protect a human hand from a blow torch flame held only ten centimetres away.

PRODUCTIVITY AND SAFETY IN THE WORKPLACE

1. Output from each worker reduces by 1.8%
2. Accidents increase by 4.5%.

EXTEND THE LIFE OR YOUR ROOF

• CoolCote™ can be applied to all types of metal and fibro roofs.
• It will extend the life of your roof by reducing expansion and contraction caused by high heat loads.
• It's elastomeric (rubbery) nature will seal small holes up to 3mm in diameter preventing leaks in winter. (It won't peel or flake.)
• It will reduce the process of oxidation by protecting the surface from water and airborne pollutants.
• CoolCote™ will reduce incoming and outgoing noise due to its ceramic sound absorbing qualities.
