Abstract:
An attempt was made to study the difference in surface temperature (both inside and outside) of different roof types during summer at the buffalo farm of LPM, LUVAS, Hisar (Haryana). The experiment was divided into four treatments viz. T1 (control): Corrugated asbestos roof; T2: Corrugated asbestos roof painted white on upper side; T3: Corrugated asbestos roof having EPE (Expanded polyethylene) sheet on lower side and T4: Corrugated asbestos roof painted white on upper side and EPE sheet on lower side. The recording of surface temperature of each roof (both inside and outside) was done at weekly intervals. The overall outside ST at 7:00 AM was significantly higher (P<0.01) in T1 and T3 as compared to T2 and T4. Similarly, the overall outside ST at 2:00 PM differed significantly (P<0.01) between the treatments except T1 and T3 which did not differ significantly and highest values were seen in T3 and lowest in T2, whereas; the overall inside ST was significantly (P<0.01) high in asbestos roof as compared to other treatments both at 7:00 AM and 2:00 PM but corresponding values did not differ significantly for T2, T3 and T4 at 7:00 AM and T3 and T4 at 2:00 PM. So it can be concluded that different roof types where EPE sheets were used as thermal insulation can reduce the temperature beneath shed upto 7 0C, while white paint with EPE sheets can lower down the temperature of shed upto 15 0C.
