Cool Roof can lower your power bills
Cool Roof reflects more of the sun’s radiation and can improve the cooling efficiency of existing buildings.
Reflects Radiation, Lessens Heat
Weathered Galv/Zincalume and Dark Coloured roofs often absorb large amounts of solar radiation which can in-turn transmit heat into occupancy zones. Cool Roofs reflect light energy in the first instance – before heat is absorbed, meaning insulation and cooling efficiencies are maximised.
Can Help Reduce Cooling Costs
Less heat penetration can lower cooling energy demand. Comparative studies identify significant cooling energy savings are possible using Cool Roof Technology.
Can Improve Occupancy Comfort
In non-air conditioned facilities such as workshops and warehousing, cool roofs can translate to cooler working and warehousing facilities.
Can Lower Carbon Footprint in Warm Climates
By lowering cooling energy demand, Cool Roofs have been identified as part of an effective mitigation strategy, to reduce global carbon emissions.
Studies in regions of the USA such as California and Florida (with similar climate patterns to parts of Australia) identify significant potential benefits that Cool Roofs may offer: energy savings, lower peak energy demand, improved health and comfort, greenhouse emission reductions.

Cooling Energy Savings will be influenced by choice of colour, Building Design (including roof pitch, materials and window placement), Insulation and Ventilation, Occupancy Use, Shading, Location, Climate, Roof Pitch and ratio of exposed roof area to floor area.
