Retractable roofs

Retractable roofs provide flexible and functional solutions for various applications.A retractable roof is a system designed to roll back the roof of a structure so that the facility's interior is open to the outdoors. Retractable roofs are sometimes referred to as operable roofs or retractable skylights.Retractable roofs are sometimes referred to as operable roofs or retractable skylights. The term operable skylight, while quite similar, refers to a skylight that opens on a hinge rather than on a track.
