Coolest commercially available paint in the world

The Solar Reflectance Index (SRI) is a measure of a material's ability to reflect solar heat and emit absorbed heat. It integrates both solar reflectance and thermal emissivity into a single number, making it an essential tool for evaluating the cooling performance of building materials, particularly in urban environments.

Pirta offers the highest commercially available solar reflectant paint in the world.
