A piece of cling film with a 25 mm air gap either side would be as good.
Its the air supplying the insulation not the foil.
You haven't seen the insulating foils, have you?
They're not a single layer, they're a quilted blanket that contains
_multiple_ airgaps. That's why they have better performance than a
single layer of clingfilm.
Only if they trap a significant amount of air, the ones I have seen don't!
There is no way they acheive the claimed insulation figures.. it isn't
possible.
If you want to argue then use two layers of cling film with a 20 mm gap and
beat the foil with ease.
