Would interesting to see real world performance over their make believe calculations.

It's the scalability of these things that means they never leave the lab.

Can't imagine Dulux will be able to start cranking out 40l tins of the stuff. Also, does it stand up to the elements? How often does it need replacing? What energy / climate cost is there to manufacture it?

Yep. I'm enough of an engineer to take their boasts with a pinch of salt.

I’ve put white K-rend in white on my new extension, and it’s cool to the touch in the heat of the sun, whereas small bits of brick are uncomfortably hot to the touch.

It is rather blinding though.
