A recent experiment conducted by some North South University undergraduate students has revealed that red rust-proof paints can help reduce excessive temperatures in homes with tin roofs.
A paper written on this technique was also presented at the International Conference on Sustainable Development 2023 held in Pokhara, Nepal, reads a press release issued on Tuesday.
As a mitigation measure to decrease the intense temperature inside tinned homes, corrugated iron sheets of similar dimensions were painted and coated in white and red rust-proof paints separately and the heat transfer was compared to the unpainted sheets used as tin roofing.
It was observed that the corrugated iron sheets coated in red rust-proof paint containing red oxide transferred the least amount of heat resulting in lower ambient room temperature.
This method was implemented on a real-life scale in poultry and it displayed staggering results by decreasing the temperature inside the poultry sheds.
Additionally, implementing this measure will increase the longevity of the corrugated iron sheets by preventing rusting.
The whole experiment was conducted by Arup Ratan Das and Tasriba Karim Sayanno, undergraduate students of the Department of Civil and Environmental Engineering of North South University, and was supervised by Dr Nadim Khandaker, professor of Civil and Environmental Engineering at North South University, and Sebha Saleem, professor of Department of Arts and Architecture at Sushant University, India.
This simplistic approach to reducing the ambient temperature of tin-roofed houses is feasible and does not require any expertise to implement it, reads the release.
