How Good They Look
Vinyl window frames are pretty plain looking, even when ordered in an interior and or exterior color other than white. It isn't to say that they look bad, but rather that vinyl windows don't draw the eye like a wood window. Instead, they tend to blend into the background. Fiberglass windows look very similar to vinyl; in fact, it's hard to distinguish the two even when up close. Fiberglass windows do tend to come in more interior and exterior colors and some fiberglass manufacturers use faux wood veneers that do an excellent job of mimicking the grain, texture and overall look of real wood.
