Weathered galvanised iron or zincalume are poor reflectors of both visible and invisible infra-red light offering significant opportunity for commercial COOL ROOF benefits.
The above photo is before painting and the one on the right is after painting.
After painting your roof with Dulux InfraCOOL® coatings:
- With a CoolRoof Commercial White over a galvanised steel roof you can expect a 44C Cooler roof surface temp on a 37C day (ie. 40C vs 84C)
- This translates as up to 5-15C cooler internal temperatures, depending on building design and level of insulation
