Don't know if anyone will offer a stock finish in a red interior, but wood, fiberglass, or a vinyl or composite with paintable/stainable interior laminate could be painted red. What window material are you looking for ?

Kolbe windows offers a prefinish interior in red but it's very expensive and when it comes to any brand it's probably more cost effective to have a painter paint the window. But the option is there.

Probably cheapest route (maybe best performing too) would be vinyl with a paintable interior.
