Can anyone tell me if there are any insulation products out at the moment, that at approx 10-20mm thick, would give the same U value in a cavity wall as say 40-60mm standard insulation board such as kingspan?

Have you seen this [broken link removed]
Ive used it in areas that are restricted to space, or to minimise cold bridging in difficult areas.it has a phycial thickness of 30mm with a claimed u equilivant to 210mm mineral wool.
I don't think this has been tested adequately yet
Thats true, but they do work and before long they should comply, this is why I would only use it if all other avenues are exhaused, ie as I said, tight suituations and cold bridging solutions.
