How it works
* As measured by Civil Aids under test conditions
Solar Radiation is absorbed by the roof. The heat which is absorbed is conducted through the roofing material to the structure and the rooms below.
Thus, we can use two broad strategies to block the heat, and keeping the building cool, namely:
1) Reflect the radiation from the outer surface of the roof, thereby not allowing the heat to be absorbed by the roof
2) Insulate the roof, so that the absorbed solar radiation is not allowed to pass through to the rooms below
Scudo is an example of the first strategy. Scudo works by reflecting away the solar radiation from its top surface itself. Scudo prevents heat from being absorbed by the roof. It reflects away the radiation, thereby not allowing the roof to absorb heat.
Most insulation materials (usually these are under-deck products) have no effect on the amount of solar radiation that is absorbed. However, the insulation ensures that the heat which is transmitted to the surface below is greatly reduced, compared to the amount of heat absorbed.
Both these products achieve the same objective of cooling, but act in very different ways. Thus the measure of their efficiency is also different.
For radiation reflection, the appropriate measures of performance are reflectance, SRI (measured by CEPT: both these tests indicate how effectively the top surface of the tile reflects away the solar radiation outwards) and surface temperature tests (as carried out by Civil Aids)
No coating is required on top of Scudo. The albedo/heat resistant property of the tile is integral to its mix.
Thus, Scudo saves you the expense of all heat-reflective coatings/paints that people use to paint on top of clay tiles. These coatings only last for 2-3 years, whereas in the case of Scudo, where the tile is integrally cast with a heat-reflecting mix, the heat-reflecting characteristic of the building is permanent.
It is not necessary to apply any sort of coating on top of the tile.
