In general, cool tiles have strong thermal emittance and solar reflectance. Cool Roof Tiles typically have a Solar Reflective Index (SFI) of 95%, which is the metric used to identify the level of heat reflectance. This indicates that under any circumstances, cool tiles can reduce heat by around 10 to 15 degrees Celsius.

SRPPL Cool Roof Tiles
A cool roof is made to reflect more sunlight than a typical roof, which results in less solar energy being absorbed. In the same way that wearing light-colored clothing keeps you cool on a hot day, this lowers the building’s temperature.
