The chances are as a pedestrian and a building user, you’ve been through a few revolving doors in your lifetime. The revolving door is a common sight amongst larger commercial buildings and in many places where there is a high foot fall.
The revolving door, usually consists of three or four doors known as wings which are spaced at an eqi-distance from each other around a central shaft. These wings rotate in a circle inside of a cylinder. The size of the cylinder can vary from small, allowing for just enough space for a single user to a larger size which allows enough room for several people, pushchairs or luggage to fit in.
It is a well-established fact that the revolving door holds many advantages over the more traditional hinged door. Not only are revolving doors more energy efficient than regular doors but they help to keep the cost of heating and cooling to a minimum. When the users of manual doors open a regular door a large amount of air can escape the building. The installation of a revolving door can help to eliminate this and the amount of air that escapes whilst the door wings of a revolving door circulates is minimal. In this way, drafts are reduced and your lobby area is kept at a comfortable temperature.
