Thermographic analysis of the superficial temperature of roof tiles

The objective of study was to get thermographic images from the surface of roof tiles to evaluate their tempertures. The evaluated treatments were: T1 - grey Coppo Venneto wave tiles; T2 - Ivory-colored Coppo Venneto wave tiles; T3 - Ivory- colored, plain tile; T4 - plain, grey roof tile; T5 - glazed clay colonial tile; T6 - Asbestos wave tile T7 - French clay tiles. Each treatment was made up of three tiles which were piled one top of the other, except for the asbestos tiles. The experimental design was in randomized block with three repetitions. The data which were collected in each set time were analyzed through the repetitive measure model, using the MIXED procedure - SAS. The temperatures of the inferior surface of the tiles were very similar throughout the day. The ivory colored tiles had better superior and inferior temperature than the grey-colored ones in their respective category. The glazed, clay colonial tile presented a larger temperature of inferior surface than the other tiles.
