Fiberglass garage doors are chosen by homeowners because of their ability to mimic the texture and stain-like finish of wood better than many other materials. You get the look of a wood door without the regular maintenance.
Fiberglass itself is a lightweight material that is typically adhered to an insulated steel garage door. The insulated steel base door makes the door more durable and sturdy and improves energy efficiency and reduces noise as the door operates.
These doors are great for coastal living, as they don’t warp, rust, or corrode like other materials do in a beachy environment. However, prolonged sun exposure can cause the door to yellow with age. While this door does well in salty coastal areas, it doesn’t hold up as well in cold climates, as the fiberglass becomes brittle in the colder months and more prone to damage.
Fiberglass is offered in limited designs and colors, which can be disappointing to someone who wants their door to stand out. But if you want your door to blend in with the rest of your home, you won’t mind the reduced design options.
