DORMA has reached new levels of design innovation with the launch of the KTV glass revolving door with glass ceiling; a development made possible by powering the door from below the central shaft, rather than above.

The inclusion of the all glass ceiling option extends the number of choices and specifications within the range available to customers. The KTV can be specified for any opening with an inside diameter from 2000 to 3400mm; plus standard fixed diameters of 3600 mm and 3800mm. The KTV series can be fitted as a two, three, or four-wing design with glazed or metal panelled drum walls and there is an option of additional internal or external night shields.


As well as offering an elegant contemporary solution and aesthetically enhancing any building frontage, the KTV’s functionality is also exceptional. It can help to reduce noise and prevent dust and debris entering the building. The opening cycle, which effectively creates an airlock, is also beneficial in the efficient regulation of temperature and air conditioning systems.


In high-rise complexes that create gusty winds, revolving doors also prevent major fluctuations in air pressure, making them safer and easier to use than conventional doors.
