This is a general guide to what windows are made of. There are many combinations of wood and vinyl, wood and aluminum, solid vinyl, vinyl with one color or woodgrain on the interior and another on the exterior etc. You can find windows with paint-able stain-able “foil” interiors as well as pre-finished versions of these. There are more than 40 different combinations of interior vinyl woodgrains for the interior surface, with solid vinyl exteriors. The technology for applying a permanent paint on the exterior makes the choices even more expansive!
