Alternative side covering

Hello folks from across the pond.
I've tracked down an interesting product (apologies if it's been posted here before which most thing have!).
It's a polythene/aluminum composite sheet, which is used for outdoor signs etc. Comes pre painted in white, and as I am playing with ideas for slightly bigger than 8x4, was pleased to see they do this in just under 5x10.
Cost here in the UK is an amazing £56 + tax for a 5x10, which is approx $107.
Just wondered what you guys thought.... cookie cuttter wall with rigid foam inserts then mainly fix the composite to the outside using Sikaflex, or VHB.
The fact you woouldn't need ply - with all the inherent worries about delamination down the line...
And if you're happy with white, it would be a flawless factoryt finish, which could look beautiful with just some good custom graphics.
Of course this is all still hyperthetical! Still can';t persuade Mrs Mallymal she really needs a teadrop, and I've been lurking on here for so many years, it's getting embrassing.
