How to design an office entrance using glass

The office entrance is the first space every visitor sees – a client, a business partner, a job candidate. This is where the first impression of the company is formed within seconds. Glass in the entrance area creates an impression of modernity, transparency and professionalism at the same time – but only if the design has been thought through technically and aesthetically. The choice of door system, glass type, hardware and layout has consequences for many years of use.

Where to start when designing a glass office entrance

Every office entrance project starts with an analysis of function and traffic. How many people will use the entrance each day? Is it an office with a reception desk and access control, or an open space with free flow? How wide must the opening be to handle peak-hour traffic?

These questions directly affect the choice of door system – leaf width, opening mechanism and duty class. A system designed for a few dozen openings a day will behave completely differently after a year of intensive use than one used several hundred times a day.

Checking the regulations is just as important. Opening widths, fire resistance at entrances to fire zones and accessibility requirements for people with disabilities must be taken into account at the very start of the design, not as corrections after the work is finished.

Which door systems work best at office entrances?

Office entrances use a few basic systems, each with its own advantages and limitations. The choice depends on the character of the space, the amount of traffic and the client’s aesthetic requirements.

A sliding system – single or double leaf – is the solution most often used for main entrances in busy offices. The leaf slides along the wall or into a wall pocket without taking up circulation space. Automatic systems remove the need to touch the door, which is an added advantage in public spaces today.

A swing system with or without an aluminium frame is an elegant, reliable solution for lower traffic. The doors open inwards or outwards, so the swing zone in front of and behind the doors must be allowed for in the layout.

A pocket system – with the leaf retracting into the wall – gives a visually clean opening with no visible door elements at the wall. However, it requires a suitable wall pocket to be prepared during construction or conversion, which can be difficult in refurbishments.

How to choose the type of glass for the entrance area

Glass in the entrance area is exposed to heavy use, impacts, varying temperatures and large differences between outdoor and indoor temperatures. The choice of glass must take these conditions into account – standard float glass is ruled out here.

Toughened glass is the basic choice for swing and sliding doors. An impact-resistant toughened panel breaks into safe pieces, which is a standard requirement for glass used in doors.

For large panels, side lights next to doors and anywhere a broken panel could fall out, laminated VSG glass is the right choice. The interlayer holds the fragments in place and gives time to leave the area safely or secure the opening.

Low-e or solar-control coatings are worth considering for entrances exposed to strong sunlight – especially facing south or west. They limit heat build-up in the entrance area and reduce the greenhouse effect without blinds or shades.

What role do the side lights next to the entrance doors play?

Side glazing next to entrance doors – vertical glass panels on one or both sides of the leaf – has a huge impact on how the whole entrance looks. A narrow door with wide side lights appears larger and more open than the door opening alone would suggest.

Glass walls framing the entrance give it a prestigious character and create visual consistency with the rest of the office. Especially at the entrances to Class A office buildings, where the first impression shapes the identity of the whole building, glazed entrance areas are an architectural standard.

The side glazing must be fixed with a system consistent with the door system. Mixing different profiles, hardware and finishes on the doors and side panels spoils the overall look and signals a lack of attention to detail, which is unacceptable at prestigious office entrances.

How does hardware affect the look and function of the entrance?

Hardware is what users touch and see every time they pass through. The pull handle, lock, hinge and door closer are the details that make up the overall impression of quality of the whole door system.

The pull handle should suit the character of the space and the weight of the leaf. A long horizontal tubular handle signals that the door is pushed open – without the need for signs. A vertical handle suggests pulling. These details make the door intuitive for visitors who do not know the building.

A door closer on entrance doors is required in many types of buildings – for regulatory and practical reasons. Doors left open mean heat loss, noise from outside and the risk of uncontrolled access. Closers concealed in the transom or in the floor are aesthetically cleaner than surface-mounted arm closers.

How do all-glass doors differ from aluminium-framed systems?

All-glass doors are systems in which the glass panel is fixed directly to hinges or a track without a frame. The glass edges are visible and become a design feature – the characteristic green-blue tint at the edge gives a look that framed systems cannot achieve.

This type of door requires toughened glass of the right thickness – usually 10 or 12 mm – and hardware fixed directly to the panel through drilled holes. The precise position of the holes is crucial, because it must be defined before toughening and cannot be corrected once the panel has been produced.

Aluminium-framed systems give more design freedom – the frame can surround the whole leaf or only part of it, and can be anodised, powder-coated or finished in various RAL colours. For projects that must match an existing facade system or the building’s joinery, an aluminium frame is often the only way to achieve fully harmonised finishes.

How to take care of acoustics in the entrance area

The office entrance is where noise from outside enters the interior. Traffic, sounds from corridors and the building lobby, conversations at reception – all of this affects acoustic comfort, especially in conference rooms and focus areas near the entrance.

Glass used in partitions near the entrance should have a suitable sound insulation rating, expressed as the Rw index. Standard single panes achieve Rw of 30–35 dB. Laminated glass with an acoustic interlayer can exceed Rw 40 dB, a noticeable difference in an office environment.

Door seals matter just as much. Leaky doors – even with excellent glass – let sound through the gaps around the leaf. Brush and compression seals at the bottom edge and at the frame effectively reduce sound transmission at these points.

How does access control integrate with a glass door system?

Modern office entrances are almost always equipped with access control – card readers, intercoms, electromagnetic locks or electric strikes. Integrating these with a glass door system needs planning at the design stage.

An electromagnetic lock on a glass door must be fixed in a way that does not spoil the look of the whole system. Concealed cable routing, neat passages through panels or profiles and a well-matched lock are what distinguish professional work from improvisation on site.

Readers and exit buttons can be fixed to the glass with special brackets or integrated into the system posts if the design requires it. A good glass door system integrator should have solutions that allow full access-control integration without aesthetic compromises.

When should you entrust the office entrance design to a glass specialist?

For any project that goes beyond standard use – large panels, non-standard dimensions, acoustic or fire requirements, integration with access control. In these situations, choosing a system yourself from catalogues carries a risk of mistakes that are hard to fix after installation.

A glass structures specialist has knowledge of systems and standards and experience from completed projects that allows a quick assessment of whether a solution will work in specific conditions. An early consultation – before materials are ordered and openings are cut in the walls – helps avoid costly corrections and delays.

A good glass systems supplier is also a partner at project handover. Technical documentation, declarations of performance and test reports are required for public buildings and cannot be put together after the fact without the right technical back-up.
