NXT Cool Zone®
Heat Reflective Roof Coating

Your Heat Reflective Roof Coating Question Answered

Can I expect the same level of savings over the entire lifetime of my roof?

The heat reflecting properties of the coating will not be reduced with age. However the coating will lose some gloss after a number of years due to normal wear and tear and this will cause loss of TSR. Flat roofs may accumulate more dirt and debris because their slope is not great enough to allow sufficient flushing by rain. Minimum maintenance such as washing flat roofs regularly will minimise degradation and maximises energy savings. Consult your roofing contractor or Nutech Paint to learn more about recommended maintenance procedures.

Will applying NXT Cool Zone® save me money no matter where I live?

Houses in very hot and sunny climates will benefit from the greatest energy and cost savings. People living in NSW, QLD and WA that use more air conditioning will see greater reductions in their energy bills than people living in Tasmania for example. Where people only use their air conditioning occasionally, NXT Cool Zone® may be of marginal benefit from an energy viewpoint, however the ultra durability of the pigments and polymers will ensure superior performance and a longer lasting coating.

How much can a home owner be expected to save by using NXT Cool Zone®?

This depends on a number of factors including:

  • The orientation of the building to the Sun
  • The colour selected
  • The local climate conditions
  • The level of insulation installed
  • The age of the NXT Cool Zone®
  • How well your coating of NXT Cool Zone® is maintained
  • The type and colour of the roof it replaces.

In general cooling energy savings can be as high as 50%. It can also reduce peak cooling demand by 10 to 15% and therefore home owners may be able to purchase smaller less expensive air conditioning systems that will run less frequently and cost less to service and replace. In the case of evaporative air conditioning significant savings of scarce water resources can be achieved.

How much can a business expect to save by using NXT Cool Zone®?

This will depend on the above factors however using NXT Cool Zone® White will ensure energy savings of 50% compared to a conventional flat dark coloured metal or weathered galvanised silver roof. A similar reduction in peak cooling demand of 10 to 15% can also be expected.

What are the benefits of NXT Cool Zone® Roof Coatings?

Save you money and energy

According to the US EPA, about one-sixth of all electricity generated in a year is consumed in building air conditioning. NXT Cool Zone® roof products can reduce the amount of air conditioning needed in buildings and can reduce energy bills by up to 50% subject to colour.

Allow you to downsize cooling equipment

NXT Cool Zone® roof coatings can reduce peak cooling demand by up to 10-15%. Home or building owners may be able to purchase a smaller, more efficient, and less expensive cooling system and reduce servicing, maintenance and replacement costs.

Decrease pollution in urban areas

Reducing energy usage also means burning of fossil fuels and less greenhouse emissions and pollution from power plants and air conditioning plant and equipment. NXT Cool Zone® roof coatings also help to reduce the "urban heat island effect." This is where dark heat absorbing buildings and paved areas make the air in our cities hotter, further increasing greenhouse emissions which result in more smog and higher health costs due to respiratory illness.

Increase roof product life

NXT Cool Zone® roof coatings maintain a more constant lower roof temperature and reduce thermal shock, which occurs when cool rain hits a hot roof, causing a sharp drop in temperature. During temperature changes, a roof expands and contracts, causing stress which can degrade the roof.

Why is NXT Cool Zone® good for our environment?

Energy produced by burning fossil fuels increases green house gas emissions and creates air pollution associated with smog, acid rain and global climate change. NXT Cool Zone® roof coatings help to reduce the production of these pollutants. Heat reflective roof products can also help reduce the "urban heat island effect." A phenomenon in which cities can be 1 to 4.5°C warmer than the surrounding countryside. These heat islands result due to dark buildings and paved surfaces which absorb heat from the Sun. This heat is released at night causing the air temperature to remain high. The higher urban temperature leads to an increased demand for air conditioning in buildings, increased petrol use for car air conditioning, increased levels of smog, and associated increased levels of heat-related and smog-related health problems. Installing reflective roofs such as NXT Cool Zone® will help reduce the urban heat island effect, decreasing the amount of smog in the air and benefiting the environment and our entire community.

What are the 5 Star House (Victorian), Green Home (NSW), Energy Smart Home (WA), 4 Star Home (SA) and Greenhouse (Federal) programs in Australia?

Climate scientists claim that we need to reduce greenhouse emissions by 80% this century to avoid global warming. These programs are State and Federal Government initiatives with the broad objectives of ensuring that home and building designs are environmentally sustainable by reducing greenhouse emissions, preserve natural resources, reduce energy and water usage and help home owners save money and live more comfortably. In an unisulated house most heat is lost and gained through the ceiling and roof – 25 to 35%. These programs recognise that this is the most important part of the home to insulate. NXT Cool Zone® can reduce energy waste by up to 50% and can play a significant role in reducing greenhouse emissions and the urban heat island effect.

What is a US EPA Energy Star roofing product?

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy aimed at saving money and protecting the environment through energy efficient products and practices. An Energy Star compliant heat reflective roof product can reduce the roof surface temperature by up to 55°C decreasing the amount of heat transferred into a buildings interior. Energy star qualified roof products save money and energy by reducing the amount of air conditioning needed to keep a building comfortable. Under this program the compliance requirement for steep roofs (>10 Degree slope) is a minimum 25% Total Solar Reflectance. NXT Cool Zone® has a minimum TSR of 35% and a maximum above 90% which is fully compliant with Energy Star.

Is NXT Cool Zone® better than ceiling insulation?

Rather than allowing the Sun to superheat the roof space, then trying to control heat transfer with ceiling insulation, it is much better to reflect heat away from the surface of the roof. The same principle applies with glass windows. It is better to stop the Sun from hitting the glass with external blinds rather than trying to deal with the problem once the heat has entered your home. In summer, external shading is much more efficient at keeping your home cool than internal blinds. Shading your windows from the outside can reduce heat gain in your home by up to 80%. NXT Cool Zone® works in a similar manner to shading your roof by reflecting the heat before it can enter the roof space. Ceiling insulation is still required for an energy efficient home, but it will work more efficiently, as peak temperatures will be much lower. Coating your roof with NXT Cool Zone® will also maximise emissivity resulting in more rapid night cooling as the temperature of the thermal building mass will be cooler and emit heat to the atmosphere more efficiently.
