Vinyl vs. Fiberglass Windows for Utah Homes: Which Is Better?

For Utah homeowners, the vinyl versus fiberglass decision is rarely about one feature alone. It is about heat, cold, sun exposure, expansion and contraction, and how much upkeep you want to deal with over time.

Utah puts windows through a lot. Summer sun can be intense, winter air gets dry and cold, and temperature swings between day and night can be rough on lower-quality frames.
