I have just seen some 25mm quitled roof insulation, that says it
acheives 0.2 U value, its about the same price as 100mm kingspan,
which is also about the same U value.

Does it work ?


not bubblewrap is it?

Put it this way, you know insulation works by trapping air and keeping
it still... what is so vastly superior about this product compared to
glass wool? How exactly does 1" of it trap and keep still more air?
