DORMA cam-action closers for £30m private estate in Gloucestershire

DORMA has supplied 40 of its TS 93 door closers to the futuristic dream home of one of Britain’s leading industrialists. Swinhay House at Wotton-under-Edge in Gloucestershire is a 60 acre private estate that displays an architecturally futuristic mix of angular, high-tech insulated metal roofing, curving bonded glass and lawned mounds that sweep up towards a series of circular stone walls.

The house is designed with 11 levels, including self-contained apartments and the elegant DORMA TS93 cam action door closer is fitted throughout as a control system on all internal aluminium fire doors and external aluminium doors. A specific design requirement that DORMA had to take in to account was for every door to open outwards, enhancing the feeling of spaciousness captured in the overall architectural design of the building. All the TS93 units are finished in a special bronze colour to complement the aluminium doors.

The Architectural Ironmongers at Swinhay House were Westland Architectural, who became involved at the initial specification stage of the process. Chris Tilling, Partner at Westland comments: “We have worked closely with DORMA before and knew there was no question about their capability. What was particularly important was that the door closers used at Swinhay met the requirement for an effective back check on all the doors. The location of the property is prone to high winds and there are situations where the doors might be caught by this. We knew that the TS93 would cope perfectly well in this environment”.

Unlike conventional rack and pinion closers the TS93 cam-action closer has a unique linear drive mechanism and heart shaped cam which means that opening forces well below 30N can be achieved when adjusted to size EN3, the power requirement for fire doors. As a result, when the door is opened the opening force falls away rapidly after the first few degrees resulting in little resistance throughout the opening cycle, yet it will always ensure full and correct closure of the door – third party test evidence to support this is available. The result is a much easier and safer door operation.

It is a versatile and elegant system providing a high-quality architectural solution for all project application requirements. With the new Contur design it offers an even more impressive specification, thanks to concealed fixings, height-adjustable G-N slide channel – power adjustability, and backcheck and delayed closing action as standard features.
