Don't bother. They work for roofs but not for walls. They reflect sunlight
on a roof. On walls, the heat transfer is mostly conductive and convective
not radiation. If you had a room or an outside temperature that was 1000oF
they might help. Then the radiation would be a bigger part of the heat
transfer and they would help.
FYI, I write this about once a year. Gay asked last year....

Has anyone out there used any of the ceramic, thermal insulating
additives you can mix into standard interior or exterior house paint?
Such additive coatings are based on tiny ceramic "microspheres" and
supposedly increase the R-value of the surface onto which they are
applied.
Hy-Tech is one brand - Kool Koat is another that we've heard of....
