Does heat reflective roof paint work?
Painting your roof with heat reflective paint can save you up to 40% on your utility bill. It can decrease your total energy consumption by 25%. As far as reducing carbon dioxide emissions, once estimates suggest that the average Australian household can reduce their contribution to this by 18 tonnes.
How effective is solar reflective paint?
In some cases these types of coatings can dissipate up to 70% of the radiant heat. By reflecting the sun’s rays and dissipating the radiant heat the internal temperature will be significantly lower. Increased durability of the substrate is a further benefit of this effect.
Are roof coatings worth it?
Coatings may be an unnecessary expense: Coatings are often considered an economical way of increasing a roof’s reflectivity to reduce cooling costs. However, a coating is not always necessary if enough insulation is installed – which negates the need for any thermal coating to help cool a roof in hot climates.
