Large and small retractable enclosures are able to operate with great speed and reliability. Aqua Sferra waterpark in Donetsk, Ukraine, for example, is housed in the world’s largest free-standing aluminum dome (standing 26 m [85 ft] high and 85 m [279 ft] in diameter).
The dome’s design uses 16 custom-built and calibrated motors to move four triangular roof panels (each measuring 24.3 m [80 ft] across the base and 24.3 m [80 ft] across the arch) along 587 m (1926 ft) of track to open the park to the outdoors.
Despite the weight and size of the four panels, the system is able to retract in less than 10 minutes. This speed allows park operators to minimize delays due to inclement weather, while also giving the park an extremely dynamic and open atmosphere that guests will remember.
The customized nature of the design and materials used to fabricate these enclosures allows each component to be tailored to meet the particular requirements of each venue’s location. Further, the retractable panels and support profiles are also fabricated to fit precisely when closed to prevent drafts.
Increasing in popularity
The use of aluminum framed retractable enclosures for aquatic venues is becoming increasingly popular among developers. The lightweight, adaptability, and natural corrosion-resistance of the support materials, along with the design possibilities the transparent glazing offers, make these enclosure systems well-suited for these facilities.
With many successful installations worldwide, the abundance of structural and design advantages retractable enclosures offer have made these systems a desirable choice for aquatic venues of all types. Facility owners can make the most of these materials and design techniques by seeking an experienced, well-equipped firm that specializes in these projects.
