I suspect you're wrong about that.  The plastic commonly called Visqueen is made from low density polyethelene, a type of
thermoplastic with a melting temperature around 230ºF.  It doesn't break down from prolonged exposure to temperatures lower than its
melt point.  Even in the SoCal desert attic temperatures never reach 230ºF unless there's a wildfire present and at that point you
have more serious concerns than the vapor attic barrier.

Heh, Angela occasionally asks me to take her on a drive up North during the winter so she can see what snow looks like up close.
She's only seen it at a distance in the Alps during several trips to Europe.  I know her better than to ever do that.  She'd make me
drive straight home the moment she fealt chilly air.  :^)
