Retractable Roof

A retractable roof is a kinetic architectural element used in many sports venues, in which a roof made of a suitable material can readily be mechanically deployed from some retracted or open position into a closed or extended position that completely covers the field of play and spectator areas. They are generally used in locales where inclement weather, extreme heat, or extreme cold are prevalent during the respective sports seasons, in order to allow for playing of traditionally outdoor sports in more favorable conditions, as well as the comfort of spectators watching games played in such weather. Unlike their predecessors, the domes built primarily during the 1960s, 1970s, and early 1980s, retractable roofs also allow for playing of the same traditionally outdoor sports in outdoor conditions when the weather is more favorable.

Another purpose of retractable roofs is to allow for growth of natural grass playing fields in environments where extreme hot and/or cold temperatures would otherwise make installation and maintenance of such a field cost prohibitive. Not limited to stadiums, retractable roofs are also used in residences, commercial buildings, swim centres, and other places with overhead enclosures. Installations throughout the world employ a variety of different configurations and styles.

Famous quotes containing the word roof:

    The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail—its roof may shake—the wind may blow through it—the storm may enter—the rain may enter—but the King of England cannot enter!—all his forces dare not cross the threshold of the ruined tenement!
    William Pitt, The Elder, Lord Chatham (1708–1778)
