As heatwaves persist across India, a man has gained attention for sharing a DIY roof cooling technique that costs less than ₹800. Instead of investing ₹20,000 to ₹30,000 in air conditioning, he uses a mixture of Fixit URP, white chuna (lime powder), and Fevicol binder to create a reflective coating on rooftops. This method reportedly lowers indoor temperatures by 15 degrees Celsius, even in extreme heat conditions. The process involves mixing the materials, cleaning the roof, applying the mixture, and allowing it to dry. Experts highlight that lighter roof surfaces absorb less heat, making this technique effective in reducing indoor temperatures. The video has sparked interest among homeowners seeking affordable cooling solutions amid rising temperatures and high electricity costs. While this method may not completely replace air conditioning, it offers a practical, energy-saving alternative for many households during summer months.
