Automatic sliding doors are used in many residential and public applications to seamlessly grant access to people. We encounter
sliding doors daily at the entrances to businesses and shopping centres. Entraway installs sliding doors.
Automatic sliding doors remain closed at all times and only open when traffic approaches. This makes it easier for the building’s air conditioning system to maintain the climate, saving significantly on electricity. Most of these doors open when an infrared beam is broken. A low-power microwave radar sensor works in much the same way. Other doors open when someone activates a pressure sensor by stepping on the doormat. They may also be manually operated by
security guards, or via electronic key cards.

Revolving doors may be preferred in applications where other types of automatic doors are not suitable. In very cold or windy places, revolving doors present a more elegant
access solution at public places.
The main reason for this is that revolving doors completely eliminate drafts.
Automatic sliding doors let in wind every time they open, unless an expensive double door solution is used. Revolving doors maintain a constant seal on at least two of their “wings” at any given time, permitting the wind no direct path into the building. Three- and
four-wing revolving doors are available that are suitable for a wide variety of applications.

Automatic doors can be triggered in several ways, but usually by a active infra red sensor that detects traffic approaching. Sensors for automatic doors are generally:
- A pressure sensor – e.g., a floor mat which reacts to the pressure of someone standing on it.
- An infrared curtain or beam that shines invisible infra red light from sensors; if someone or something blocks the beam the door is triggered open.
- A motion sensor that uses low-power microwave radar for the same effect.
- A remote sensor (e.g. based on infrared or radio waves) can be triggered by a portable remote control, or is installed inside a vehicle. These are popular for garage doors.
- A switch that is operated manually, perhaps after security checks by a guard. This can be a push button switch or a swipe card.
Automatic doors are essential for climate control and useful for the safe passage and entrance for the disabled.

It is often useful to have doors that slide along tracks, often for space or aesthetic considerations. Sliding glass doors are common in many houses, particularly as an entrance to the backyard or to a patio. Such doors are also popular for use for the entrances to commercial structures. Sliding doors are helpful in maintaining the indoor climate and can save enormously on energy costs. Entraway’s sliding doors help maintain a comfortable climate and save on energy costs. The units can be adapted to a wide range of different door and customer requirements. All of our sliding doors Integrate easily with our access control systems and are useful for safe the passage and entrance of the disabled.
