Fiberglass pools offer numerous advantages over old-fashioned concrete pools and does not have the many durability questions typically associated with vinyl liners. With vinyl-ester and ceramic blended resins, manufacturers have eliminated all surface and structural problems that may occur due to materials used or manufacturing methods. The surface of a fiberglass pool is satin smooth, not rough and abrasive. The fiberglass composite is an inert material, which will not affect water chemistry and prohibits algae penetration. Fiberglass simplifies maintenance on average 80% more than old fashion concrete pools.
