The whitest-ever paint has been produced by academic researchers, with the aim of boosting the cooling of buildings and tackling the climate crisis.

The new paint reflects 98% of sunlight as well as radiating infrared heat through the atmosphere into space. In tests, it cooled surfaces by 4.5C below the ambient temperature, even in strong sunlight. The researchers said the paint could be on the market in one or two years.

 

Guardian online.

 

Could be good for grow room walls etc.

You'd be cheaper just getting the Miro sheeting as its 94 or 96% reflective or a tin of Dulux Ultra white.

Why? How much is it going to cost?
