Fiberbuilt flight decks come in a variety of thicknesses depending on the specific model and purpose. However, as a general guideline, most Fiberbuilt flight decks are around 1 inch (2.54 cm) thick. This thickness is designed to provide a stable surface for golfers to practice their swings and absorb the impact of golf balls, while also being durable and long-lasting. It’s worth noting that some models may have thicker or thinner decks depending on their intended use, so it’s always a good idea to check the specifications of a particular Fiberbuilt flight deck before purchasing.
