Vinyl vs. Fiberglass – how do they compare in cost?
Fiberglass windows cost nearly double what a good vinyl window costs, and they are less thermally efficient. On a cost/benefit or “payback” basis, a person is much better off spending money on an upgraded insulated glass package if they want a premium window that is actually better. We all know that roughly 80% of a windows area is insulated glass anyway. The frame material is of little significance. And, for the 20% of the window are that is made up of the framing material, vinyl is better!
