100mm Kingspan v's 100mm Aeroboard Platinum

[hanorac]

I'm at insulation under floor stage and contracted both of the mentioned above, both gave the same u value for 100mm, my building supplies peoples said Kingspan was better still significiently better.
Anyone got an opinion, the KS will cost me 4.5k while the A P is 2.5.
