Skycool reflective coating used to cool schools

Demountable classrooms provide a solid test for Skycool reflective coating. For the following reasons, they are very difficult to keep cool:                    

• Open windows and ceiling fans permit a high rate of external air exchange bringing in the hotter outside air which SkyCool reflective coating has to constantly re-cool. 
• Uunlike supermarkets or warehouses, much more of the solar energy enters the occupied space through the walls than the roof. 
• Sub-roof insulation tends to trap in any heat entering the structure through windows and walls (as well as internally generated heat), keeping it away from SkyCool reflective coating's ability to radiate it into space.
