Properties |
Scudo Tiles |
Clay |
Surface Coatings & Albedo paints |
Lower Surface Temperature – transmitted temperature to the roof slab |
9-10 degrees cooler bottom surface temperature compared to traditional clay tiles |

Strength (Transverse) |
3.5-4N/mm2 |
2-3N/mm2 |

Water Absorption |
Less than 4.5% |
15-20% |
Any rupture in the coating will result in direct water contact with the roof. |
Thickness |
20mm |
12 – 15 mm |
50 microns |
Bond with substrate |
Permanent |
10 – 15 years |
3 – 5 years only |
Maintenance |
No moss or dirt formation due to low water absorption. |
Moss & dirt formation requires maintenance due to high water absorption. |
Needs expensive re-coating every 5 years. |
Longevity |
Lasts as long as the building. |
Will pitt / crack after 15 – 20 years. |
Lasts for 3 – 5 years only. |
Cost Economics |
Lowest use age costs. Proactively saves energy and costs. |
Much higher use age costs due to maintenance and replacements. |
Extremely high needing recoating every 5 years. |
