Choosing between an automatic sliding door and an automatic swing door is usually the first decision when upgrading a shop entrance, and it is rarely just about looks. The right answer depends on the width of your opening, how many people come through each hour, and what your building will physically allow. Here is how the two compare in practice, based on the kinds of premises we see across Staffordshire.
An automatic sliding door has one or two leaves that run sideways along a track above the opening, so the door disappears to the side when someone approaches. A swing door is closer to a traditional shop door, hinged at one edge, but fitted with an operator that opens and closes it for the customer.
The practical difference is where the door goes when it opens. A slider needs clear wall space to either side for the leaves to park; a swing door needs clear floor space in front of or behind the leaf. That single point rules out one option or the other in a surprising number of older shop units, particularly narrow-fronted premises in town centre terraces where there is simply no side wall for a slider to run along.
Sliding doors handle heavy, two-way footfall better. Because the leaves move out of the way completely, people can pass in both directions at once through a clear opening of typically 900 mm to 2000 mm or more. For a busy convenience store, pharmacy or supermarket entrance, a bi-parting slider is usually the sensible default.
Swing doors suit lower footfall and narrower frontages. A single automated swing leaf gives a clear width of around 800 mm to 1000 mm, which meets accessibility needs for wheelchair users and pushchairs, but it creates a swept zone that people must stand clear of. On a pavement-fronted shop, an outward-opening swing leaf can conflict with passers-by, which is worth checking before you commit.
As a rough guide, automating an existing hinged door with a swing operator tends to be the cheaper route, often somewhere in the low thousands of pounds installed, while a new automatic sliding door set with glazing, track and sensors is typically more, commonly in the £3,000 to £7,000 range depending on size and specification. Exact figures depend on the opening, the glass specification, and whether structural work is needed above the door to carry the track.
Ongoing costs are broadly similar. Both types should have a planned service at least once a year under BS EN 16005, the safety standard covering powered pedestrian doors, and busy entrances benefit from six-monthly visits. Sliders have more moving parts in the track and rollers, so grit and floor debris matter more; swing operators are simpler mechanically but their arms and hinges take a pounding if the door is regularly pushed by impatient customers.
Heat loss is worth a thought too. A sliding door that opens fully for every passer-by on a cold day lets a lot of warm air out, though most modern operators let you reduce the opening width in winter. Swing doors open for a shorter cycle but leave the whole doorway exposed while the leaf swings through.
In our experience locally, retail units on high streets in places like Stone, Stafford and Stoke-on-Trent often end up with swing operators, because Victorian and inter-war shopfronts rarely have the side wall needed for a slider, and landlords or conservation officers may want the original frontage kept. Automating the existing door is often the least disruptive answer.
Purpose-built units, retail parks and newer premises with wide glazed frontages almost always suit sliders, and that is what customers expect at that kind of entrance. If you are unsure, the honest starting point is a site survey: measuring the structural opening, checking what is above the door, and looking at how people actually approach the entrance usually settles the question quickly.
Often yes. If your current hinged door and frame are sound, a surface-mounted swing operator can automate it for considerably less than a full new door set, though safety sensors and sometimes finger guards will need adding to comply with BS EN 16005.
Both are safe when installed and maintained to BS EN 16005, with sensors that detect people in the door's path. Sliding doors have the edge in crowded entrances because there is no leaf swinging into the space where people stand.
A swing operator on an existing door is usually fitted in a day. A full sliding door replacement typically takes one to two days, and most installers can keep a temporary opening or work around trading hours so you rarely need to close completely.
