Tri-Iso Super 9 is the stuff with multiple layers of foil. No-one has
actually proved it works. There are a few other copycat versions
around, the manufacturers of which haven't even bothered to try and
prove it works.

Alreflex (and a few copycat versions) is the foil faced bubble-wrap.
It has been proven to work in a wall cavity where it has the same
resistance value as 32mm Celotex or 56mm of mineral fibre batts,
neither of which would be enough by themselves to comply with the
maximum U-value required by the Building Regulations for a standard
cavity wall. The makers have tried to claim a use for it as roof
insulation and even a breather membrane, which is completely ludicrous
as it's _less_ breathable than normal roofing felt.

You would be better off trying sprayed on insulation or some sort of polyurethane board insulation.
