Aluminized mylar is easy to come by in the form of mylar punched-tape 
stock.  It is quite expensive these days, but a single roll would go a 
long way.  Also, aluminized mylar is widely used in balloons and novelty
items, which could be harvested for material.  I have no idea if the 
thickness is critical, but this sort of material would likely be much 
more conformant than aluminum foil.
