Clip-In vs Traditional Shopfront Systems

Clip-in shopfront system — here is what South African buyers need to know, with supply, installation and service from Coetz Glazing.

Aluminium shopfronts can be glazed in different ways. The clip-in system (a 44 mm aluminium shopfront framing system) uses snap-in glazing beads for fast, clean glazing and reglazing, while traditional shopfront systems rely on older putty or screw-fixed bead methods. For modern commercial frontages, the clip-in approach has become the standard — here’s why, and when a traditional system still has a place.

Quick comparison

Feature	Clip-In System	Traditional Systems
Glazing method	Snap-in clip beads	Putty or screw-fixed beads
Install speed	Fast	Slower, more labour
Reglazing	Quick — unclip and replace	Fiddly — remove putty/screws
Sightlines	Clean, slim, modern	Bulkier, dated
Maintenance	Low	Higher — putty perishes
Best for	Modern retail & commercial fronts	Repairs to existing old systems

How the glazing works

The clip-in system uses aluminium glazing beads that clip firmly into the frame, holding the glass securely with neat gaskets and no messy putty. Traditional systems bed the glass in putty or hold it with screwed beads — a method that works but is slower to fit, harder to reglaze and prone to the putty perishing over time.

Installation & reglazing

Clip-in beads make both the original glazing and any future reglazing quick and clean — a real advantage for busy retail sites where downtime costs money. If a pane is damaged, the bead simply unclips, the glass is swapped, and the bead clips back. Traditional systems take longer to fit and to repair, and reglazing can be messy.

Looks, durability & when traditional still fits

The clip-in system gives slim, modern sightlines and low-maintenance aluminium durability that suits today’s commercial frontages. Traditional systems tend to look bulkier and dated and need more upkeep. That said, a traditional system may still be the right call when you’re matching or repairing an existing older frontage rather than building new.

How a clip-in shopfront system is put together

A clip-in shopfront system is built from a family of extruded aluminium sections that lock together into a single frame. Heads run along the top, sills along the bottom, and vertical mullions and horizontal transoms divide the frontage into individual glazing panels. Each section has a glazing pocket on one side and a groove for a clip-in bead on the other. On our clip-in shopfront system, the main sections are 44 mm deep, which gives a slim sightline from the street while still carrying commercial glass sizes.

The glass sits in the pocket against a rubber gasket. Once the pane is in place, an aluminium bead is pressed into the groove and clips home, holding the glass firmly against a second gasket on the inside. There is no putty to cure and no row of screws to drive, so the glazing line stays clean and even across the whole frontage. That simple principle is what makes a clip-in shopfront system faster to install and easier to maintain than the older methods described above.

Because every panel uses the same pocket and bead, a clip-in shopfront system can be laid out in almost any grid. Tall single panes, fanlights above doors, stall-riser panels at the base and side panels beside an entrance can all be combined in one frame without changing the glazing method from one opening to the next.

Glass options in a clip-in shopfront system

Our standard glass in a clip-in shopfront system is 6.38 mm clear laminated safety glass. Laminated glass has a plastic interlayer bonded between two sheets, so if it breaks the fragments stay attached to the interlayer instead of falling out of the frame. In a busy public frontage that matters: a damaged pane stays in place and can be replaced in a planned way.

Where the shopfront faces the afternoon sun or needs privacy, the same clip-in shopfront system can take tinted, reflective or translucent laminated glass instead of clear, quoted separately. The glazing method is identical; only the glass changes. Doors, the glass beside doors and low-level panes are the positions where safety glass matters most, and our guide to commercial shopfront glazing requirements explains how those positions are identified before the glass is ordered.

Doors in a clip-in shopfront system

Entrances are designed into a clip-in shopfront system from the start rather than added later. A hinged shopfront door hangs within the same framing as the fixed glass around it, so the sightlines line up across the frontage. Where traffic is heavy, the opening can instead be fitted with an automatic sliding door such as the MC-125, or an automatic swing operator such as the MCW-100 on a single door.

An automatic entrance needs two things from the shopfront: space in the head for the operator and track, and a sound floor for the guides. Planning both at the design stage means the operator housing sits neatly within the clip-in shopfront system and the frontage reads as one piece, instead of an automatic door boxed onto an existing frame. The entrance also needs a plan for after-hours locking, whether that is an electric lock on the operator, a key switch or a link to the building’s access control.

Finishes and colours

The aluminium sections of a clip-in shopfront system are finished in black, white, bronze, charcoal or natural anodised. White, bronze and charcoal are our base price; black and natural anodised carry a premium. The same finish is used on the frame, the beads and the doors, so a new clip-in shopfront system can match an existing building or set a completely new look for a store.

Reglazing after damage or a break-in

This is where a clip-in shopfront system earns its keep. When a pane is cracked or broken, the bead on the inside is unclipped, the damaged laminated pane is removed, a new pane is set into the gasket and the bead is clipped back. There is no old putty to cut out and no screws to drill out of a weathered frame, so the opening is closed again quickly and neatly.

For a store, that speed is the difference between trading the next morning and boarding up the frontage. It is also why the glazing on the inside face of a clip-in shopfront system matters: beads on the inside cannot be removed from the street, which helps the frontage stay secure.

Maintaining a clip-in shopfront system

A clip-in shopfront system needs very little maintenance, but a short routine keeps it looking and working as it should:

• Clean the aluminium with mild soapy water and a soft cloth; avoid abrasive pads and harsh solvents on powder coat and anodised finishes.
• Check the gaskets around the glass for gaps or perished rubber, especially on the side facing the sun.
• Keep drainage slots in sills clear of dust and debris so water can escape.
• Check door hinges, pivots and locks on a manual door, and keep a regular service routine on an automatic entrance.
• Replace any damaged pane with the same type and thickness of safety glass as the original.

Done regularly, this keeps a clip-in shopfront system weather-tight and good-looking for many years, and it helps catch small faults before they become a safety issue.

Upgrading a traditional shopfront to a clip-in shopfront system

Many older frontages still use putty-glazed or screw-beaded framing. When those frames are sound and only a pane or two needs replacing, a like-for-like repair can be the sensible choice. When the frame itself is corroded, out of square, leaking or simply dated, replacing it with a clip-in shopfront system is usually the better long-term investment.

An upgrade starts with a site survey of the existing opening: the overall sizes, the condition of the structure around it, where the doors need to be and how the space will be used. Inside a shopping centre, the work also has to suit centre management’s requirements and trading hours. The new clip-in shopfront system is then made to the measured sizes so that the old frontage can be removed and the new one fitted with as little time out of trade as possible.

Security and a clip-in shopfront system

A shopfront is the most exposed part of most commercial buildings, so security is part of the design rather than an afterthought. In a clip-in shopfront system the beads are placed on the inside face of the frame, which means the glass cannot be unclipped from the street. Laminated safety glass adds a second layer of protection: when it is struck, the interlayer holds the broken pane together and keeps the opening closed instead of leaving a clear hole.

The entrance is the other point to plan carefully. Hinged and pivot doors can take commercial locks, and an automatic entrance can be locked electrically after hours or tied into the building’s access control so that it only opens for authorised staff. Agreeing how the frontage will be secured at night before the clip-in shopfront system is ordered avoids changing hardware once it is installed.

Weather, sun and a clip-in shopfront system

Shopfronts in South Africa face hard sun, summer storms and wind-driven rain. A clip-in shopfront system deals with water through continuous gaskets around every pane and drainage paths in the sills that let any water that gets past the outer seal escape back outside. Keeping those drainage slots clear is the single most useful maintenance task on a frontage that faces the weather.

Heat and glare are handled through the glass rather than the frame. A west- or north-facing store that struggles with afternoon sun can use tinted or reflective laminated glass in the same shopfront system, reducing glare on displays and screens without changing the framing. Tinted glass is quoted separately. Where a frontage is tall, large or on an exposed site, the frame sizes and mullion spacing should also be confirmed for wind loading on that particular building.

Clip-in shopfront system or frameless glass?

Frameless glass frontages are sometimes chosen for a high-end look with almost no visible framing. They rely on thicker toughened or laminated panels, specialist fixings and careful detailing, and they generally cost more and take longer to repair. A clip-in shopfront system gives a slim, modern frame with standard glass sizes, simpler reglazing and easier integration of doors and automatic entrances.

For most retail stores, restaurants, offices and showrooms, a clip-in shopfront system is the practical balance of appearance, cost, speed and serviceability. Frameless glass tends to suit flagship stores where the look justifies the extra cost and the slower, more specialised repairs.

Whichever route you prefer, the starting point is the same: the size of the opening, how the space will be used and how the entrance needs to work. Send us those details and we will recommend the clip-in shopfront system layout, glass and door options that suit your frontage.

Working inside a trading centre

Many new frontages are installed in shopping centres where the neighbouring stores stay open throughout the work. That brings practical requirements that are worth planning for from the first conversation: approval of the drawings by centre management, agreed working hours, hoarding to keep the public away from the work area, and a clean site at the end of each day.

The order of work matters too. Measuring the opening once the old frontage is exposed, making the new frame to those sizes, and then removing the old front and fitting the new one in a short, planned window keeps the time a store is closed to a minimum. Doors and automatic entrances are commissioned and tested before the hoarding comes down, so the store opens with an entrance that already works properly.

If you are fitting out a new tenancy, share the centre’s tenant design criteria with us early. Requirements for frame colour, glass type, signage zones above the entrance and door positions are much easier to meet when they are part of the design rather than discovered at the approval stage.

After handover, keep the frame finish, glass type and door details with your store records. When a pane needs replacing years later, or the centre asks for changes during a refurbishment, having those details on file means the right parts can be ordered first time and the frontage stays consistent with the rest of the building. It also makes it simple for a new store manager to see exactly what was installed, who installed it and how the entrance should be looked after.

Getting a quote for a clip-in shopfront system

To price a clip-in shopfront system accurately, it helps to send us:

• The overall width and height of the frontage, and the position of any doors
• A few photos of the existing opening, inside and out
• How the space will be used: retail, restaurant, office or showroom
• Whether you want a manual door or an automatic entrance
• Your preferred frame finish and glass type

With that information we can lay out the clip-in shopfront system, confirm the glass for each position and give you a clear quotation for supply, installation and service.
