When comparing the performance of the two different materials, fiberglass is inarguably a “better” material than vinyl. However, when considering the price difference between the two materials, the argument about which material is “better” really boils down to your budget and personal preferences. Fiberglass is more energy-efficient, durable, and low-maintenance than vinyl. Vinyl is more affordable and easier to clean than fiberglass. Ultimately, the best material for you will depend on your individual needs and budget.
