Not used it but I would be instinctively wary of anything with such a naff name.
Let alone one making claims like, "It is one of the most effective ways to insulate your home/building today".
Or anything claiming to be insulation that does not quote any actual insulation performance figures such as thermal conductivity.

Unless it is an unbelievably good insulator (which is pretty unlikely given the nature and cost of the best insulating materials) then 10-40mm is not going to be very effective just because it is not thick enough.

And if that doesn't tell you enough already then a quick look at the Thermakote web site should help. It's gone... just someone cyber-squatting on it now. And the company appears to be dissolved... company formed in Jan 2011, gone in May 2012.

Looking at the internet archive, the web site back in January 2012 include a page on "Independent Testing" that has a map of the world and just says:-

"Our products have been independently tested by world leading laboratories and government bodies for a variety of applications.

Each product is subjected to rigorous testing under strict laboratory conditions and independent testing has proved scientifically that “Thermakote products achieve outstanding results.” "


There is another company called Thermakote UK ltd but it is very new and doesn't appear to do anything.

So all things considered - I don't think I would risk it.

This stuff was at EcoBuild. No outlandish claims, thermal conductivity about what you'd expect but you'd need thickish layers anyway. No idea on pricing though.
