Revolving doors are exceptional in that they are always open, yet always closed. Truly elegant in design, they are some of the most cost effective exterior doors available on the market. Studies show that the payback on a typical revolving door can be seen as early as two to three years after the installation. These doors are practical because they protect areas in close proximity to entrances from wind gusts, noises and outside elements, which allows for more usable square footage in your facility. Security revolving doors, large diameter revolving doors, and automatic revolving doors are a few of the specialty applications Door Direct offers.
