weather resistant plastic films for lamination?


We are looking for a weather (including UV) resistant, flexible polymer film to be laminated to extruded polystyrene foam.  Desired service life is ~30 years.  Tall order, I know.  To date we have identified the following candidates:

1.5 mil bondable Tedlar.
Roofing membranes such as TPO, PVC, and EPDM.
A proprietary paint system that is supposedly also "fireproof".

If anyone can think of anything else I'd appreciate it.  We would like to keep the cost under $0.40/sf.

We don't want to use anything metallic because per UL and the NEC, it has to be grounded, significantly increasing costs.

Kynar is a coating used on aluminum roofs as a weather seal.
