DORMAs RST features a unique operating method that allows the door to provide an opening nearly as wide as the clear structural opening width itself. This is achieved by a swivel movement where the pivot centres are located off-centre, above and below the door opening, resulting in the doors first swinging open and then moving sideways all contained in a minimum sweep area.
DORMA RST space-saver doors are available in standard sizes ready to install, or as customised units to suit individual requirements. There is a choice between elegant fine-framed system with all-glass look and a rugged aluminium frame system. The RST, which helps meet DDA requirements, can also be used on emergency escape routes as it is possible to open the doors like a normal hinged doors in an emergency.
The opening of the new South Churchyard of St Pauls Cathedral is part of a £40m campaign to clean and restore the famous 17th century building, and has been designed as a peaceful and contemplative open space for visitors.
