windows are black or dark brown, You wont
warp or get to 150 - 160f ever. You wont even get to 100 in winter.

this is untrue....try a simple thermometer placed between the storm and a
window even in the winter time....winter time is less extreme, but full sun in
summer will *very* quickly exceed the 150-160 degrees necessary to warp
vinyl...this is all assuming the storm windows actually seal decent....this is
precisely why vinyl window manufacturers will NOT warantee a vinyl window that
was used in conjunction with a storm window(in my area , not sure of others..)
