MF ServicesThese systems do more than impress—they serve a vital function in modern building design. This guide breaks down exactly what an automatic door is, how it works, the various types available, where you’ll find them, and why they’ve become an essential feature in everything from retail to healthcare.
Whether you’re upgrading a facility or simply curious about the technology, this article will give you a complete understanding of automatic doors and the future of seamless access.
An automatic door is a self-opening and closing entry system powered by motion or presence detection technology. These doors eliminate the need for physical contact and respond instantly when someone approaches—offering not only convenience, but also compliance with modern accessibility and hygiene standards.
At its core, the system combines a few key components: a sensor to detect motion or presence, a control unit that processes the input, and a motorised mechanism that moves the door. The entire process happens in seconds and is designed to function smoothly throughout thousands of daily cycles.
Automatic doors are now considered a must-have in any high-traffic or customer-facing environment—not just a luxury.
Depending on the space, purpose, and traffic level, automatic doors come in a variety of styles—each with its own operational mechanism and ideal use case.
Sliding doors are perhaps the most familiar. You’ll often see them at supermarket entrances or busy retail environments where large volumes of people need easy, uninterrupted flow. Their linear movement and sensor precision make them ideal for wide spaces.
Swing doors, by contrast, are better suited for narrower passages such as internal office corridors, hospitals, or places where wall space is limited. They pivot like a standard door but are triggered automatically, often in one direction.
Revolving doors combine aesthetics and energy efficiency. These are designed to reduce airflow between indoor and outdoor environments, maintaining internal temperature while allowing continuous entry. Hotels and corporate buildings favour them for their visual appeal and performance.
Where space is tight, telescopic sliding doors or folding door systems provide creative solutions. They allow wider openings in compact areas, often used in specialty architecture or retrofits.
And for high-impact visual design, curved or angled automatic doors blend function with architectural sophistication, offering seamless movement and a unique building signature.

While it might look effortless, there’s serious technology behind that smooth open-and-close motion. Here’s what happens behind the scenes.
The process starts with sensors—usually infrared, microwave, or a combination of both—mounted above or near the door. These sensors detect motion or body heat and send a signal to the door’s control unit. The controller, often a programmable microprocessor, interprets this data and activates the motor and door operator.
Depending on the type of door, this operator may use a belt drive, gear system, or hydraulic mechanism to open the door. Once you’ve passed through, the system automatically initiates the closing sequence after a short, timed delay.
Modern systems also include safety features like obstacle detection, emergency override functions, and even battery backup in case of power failure. This ensures the door is safe, functional, and compliant with accessibility laws.
Automatic doors are far more than a convenience. In many environments, they’re essential—and in some cases, required by regulation.
First, there’s accessibility. For individuals with mobility challenges, an automatic door isn’t a feature—it’s freedom. Whether installed in a hospital, school, or retail location, these doors ensure full compliance with legal accessibility standards like the Equality Act or ADA.
Then there’s hygiene. Especially in healthcare, foodservice, or cleanroom settings, the touchless design helps prevent the spread of germs. Since 2020, this has become a top priority for businesses worldwide.
Energy efficiency is another often-overlooked advantage. By opening only when needed and sealing quickly after, automatic doors help maintain consistent internal temperatures. That translates into lower heating and cooling costs—and in some cases, better performance in sustainability assessments like BREEAM or LEED.
And don’t underestimate security. Many systems integrate with access control and locking hardware to allow only authorised access, making them ideal for secure facilities.
Automatic doors have become an everyday feature in locations where traffic meets purpose—balancing access with control.
In retail, they support heavy customer footfall while maintaining climate control. Supermarkets, malls, and convenience stores rely on them for performance and presentation.
In the healthcare sector, from clinics to hospitals and cleanrooms, doors must open hands-free and close securely to prevent cross-contamination. Systems here are often designed with airtight seals and specialist materials.
They’re also widely used in hotels, airports, banks, and corporate headquarters. Anywhere there’s a high standard for ease of entry, safety, and design, automatic doors deliver.

Installing an automatic door system isn’t plug-and-play—it requires planning, compliance checks, and ongoing care.
Before installation, a site audit will determine the best door type based on available space, wall structure, and foot traffic. Door specifications must also align with safety standards such as EN 16005 (EU) or BS 7036.
Installation should always be handled by certified professionals. Poor installation not only voids warranties but could pose safety hazards or breach compliance.
Once installed, maintenance matters. Sensors must be cleaned and tested regularly, mechanical parts lubricated, and safety mechanisms inspected. Preventative servicing helps reduce downtime and ensures long-term reliability.
At MF Services, we offer full installation and maintenance support to ensure your doors keep moving smoothly—day in, day out.
The future of automatic doors lies in smart integration. As buildings get smarter, so do their access points.
We’re seeing growing adoption of mobile access technology, RFID, and facial recognition systems—all of which can integrate with automatic door controls. Some systems are also equipped with energy monitoring features, allowing property managers to track and optimise door performance in real time.
Expect more customisation, predictive automation, and self-diagnostic capabilities in the years ahead. These aren’t just doors anymore—they’re digital gateways that sync with your entire facility.
It’s a small piece of technology with a big impact. From smoother traffic flow and improved hygiene to enhanced accessibility and building efficiency, automatic doors are part of what makes a space feel modern, secure, and intuitive.
They open silently when you need them to—and just as quickly, fade into the background. That’s good design, good technology, and a smart investment.
Whether you’re planning a retrofit, new construction, or simply exploring options, MF Services offers expert advice, reliable installation, and tailored solutions to suit your building’s needs.
