Automatic Door Glass Requirements

← Glass & Glazing Compliance Centre

Automatic door glass has to be right on two fronts: safe for the public, and suited to the operator that moves it.

What glass do automatic doors need?
Automatic entrances are high-traffic, public human-impact positions, so appropriate safety glazing is a central consideration. The glass also has to suit the door operator — its size and weight within the operator’s intended range — and work with the sensing and safety features. The exact specification is confirmed for the specific door and operator.
Please note: This guide is general practical information and does not replace the applicable standards, the operator manufacturer’s specifications or professional advice. Glass, operator and safety details must be confirmed for the specific door and installation.

An automatic door combines glazing with a powered operator in a busy, public setting — so its glass has to be right on two fronts: safe for the people using it, and suited to the operator that moves it. This guide covers the main automatic-door glass considerations, with the specifics always confirmed against the operator’s specifications and the applicable requirements.

Safety glazing for entrances: automatic door glass

Entrances are exactly the kind of high-traffic, human-impact location where safety glazing is commonly expected. The glass in an automatic door and its adjacent screens should be a safety glazing material to SANS 1263 and permanently marked. Both laminated and toughened are used; laminated’s containment can be valued at a public entrance, but the right choice depends on the application.

Framed vs frameless entrances

Automatic entrances come framed (aluminium-framed glass leaves) or frameless (all-glass with minimal framing). Framed systems suit most commercial entrances and integrate readily with shopfronts; frameless gives a cleaner look but places more emphasis on glass type, edgework and fittings. Either way, the glazing and the operator must be designed together.

Door mass and operator compatibility

The door is set within a clean, light-grey façade with subtle architectural lines. Mid-morning natural light reflects softly off the glass, creating gentle highlights along the metal edges while the interior beyond remains slightly blurred. Captured at eye level with a slight angle to emphasize the door’s motion and mechanism, the composition follows a clean, modern, photographic realism style, conveying reliability, professionalism, and effortless accessibility with sharp focus and minimal distractions in the background.

A powered operator is designed to move a door within a certain size and weight range. Because glass adds significant mass, the glazed leaf must fall within what the chosen operator is intended to handle — heavier or larger leaves need an operator suited to them. Coetz supplies the MC-125 automatic sliding door system and the MCW-100 swing door operator; the appropriate operator and glazing for a given opening are confirmed against the product specifications rather than assumed.

Sensors, safety features and access control

Automatic doors rely on sensors to detect people and to stop or reverse safely — a core safety function alongside the glass itself. Where the entrance uses access control (card, keypad, intercom), it should be planned with the operator and door. Getting the sensing, safe opening and closing behaviour and access integration right is as important to safety as the glass specification.

The door sits within a smooth, light-painted wall with clear signage and a polished tiled floor reflecting the lower edge of the frame. Cool, even fluorescent ceiling lighting casts soft, controlled shadows beneath the operator unit, emphasizing its form without harsh contrasts. Photographed from a slightly low angle with sharp focus, the composition highlights the operator as the hero element while the corridor gently fades into a subtle bokeh. The atmosphere is professional, orderly, and technologically advanced, in a clean, photographic realism style.

Opening dimensions and installation tolerances

The opening dimensions drive the door configuration (single-slide, bi-parting, single or double swing), and automatic doors are sensitive to installation tolerances — they need to be set square and true to run reliably. This is specialist installation work, and the glass, operator and opening should be confirmed together for the specific door.

Automatic door glass in summary

In summary, automatic door glass should be appropriate safety glazing for a public entrance, and the glazed leaf must fall within the operator’s intended size and weight range. The glass, sensors and access control are specified together, so automatic door glass is confirmed for the specific door and operator.

What affects the price of automatic door glass

Two quotations for automatic door glass can differ widely, and the reason is almost always a specification difference rather than a margin difference. These are the variables that move the number.

  • The structural opening. Measure the brickwork opening rather than an existing frame, and note whether the reveal is square.
  • Traffic and duty cycle. A quiet office entrance and a centre entrance passing thousands of people a day are not the same specification.
  • Power and controls. Confirm what supply reaches the head of the opening, and whether access control, an intercom or a fire panel must interface.
  • Glass. Coetz™ glazes as standard with 6.38 mm clear laminated safety glass.
  • Service access. Automatic door systems are installed and serviced by our team, so plan for periodic servicing from day one.
