Imagine a wall that knows when you’re cold.Or one that quietly reflects sunlight on a scorching afternoon—no switches, no sensors, just science. Thermal paints, or thermochromic coatings, are reshaping how we think about sustainability in design. Made with heat-sensitive pigments, these paints respond to temperature changes by altering their reflectivity. When it’s warm, they bounce sunlight away, keeping interiors cooler; when it’s cold, they absorb heat, helping retain warm
