Wont the insulation layer be so thin that it will have effectively zero
effect on heat loss or gain ??
This stuff or similar is available here in NZ also, but I cannot see how it
would make difference, am in the process of renovating a house and doing
lots of painting. Still not tempted to buy it.

I looked at the website for the product. It is not really an insulator. It is
a reflector, like aluminum foil. Anyway it makes paint behave like aluminum
foil, reflecting radiant heat.

Here is an interesting article that was produced by the US government
about 70 years ago dealing with the difference in performance with
radiators and metallic paints. Different applications but
approximatly the same tempature differental. They observed a 10-20%
increase in heat transfer with high radiation versus low radiation
coatings. In fact they seem to be recommending painting radiators with
metallic paints in smaller rooms and pigmented paints in larger rooms
in order to customize the heat flow.
