If you’re specifying a glass balustrade, you’ll quickly discover that selecting the glass is only part of the process. Equally important is deciding how the balustrade will be fixed to the building<\/strong>.<\/p>\n\n\n\n

The mounting type affects far more than appearance. It influences structural performance, waterproofing, drainage, installation methods, maintenance access and even how much usable space remains on a balcony or terrace. Choosing the wrong mounting method can lead to installation challenges, compromised waterproofing, unnecessary structural work, or a finished result that doesn’t meet the architect’s vision.<\/p>\n\n\n\n

At ONLEVEL, we’ve supplied glass balustrade systems for residential, commercial, and public projects across Europe. One of the first decisions made during system selection is determining the most appropriate mounting type for the building’s structure and intended use.<\/p>\n\n\n\n

In this guide, you\u2019ll learn what mounting types are, the key differences between top, side, and recessed mounting, when each option is most suitable, and which ONLEVEL systems are designed for each application.<\/p>\n\n\n\n

What Is the Mounting Type?<\/h2>\n\n\n\n

The mounting type defines how and where the base profile of a glass balustrade is fixed to the supporting structure<\/strong>. It does not refer to the glass itself, but to the connection between the aluminium profile and the building.<\/p>\n\n\n\n

This choice affects the architectural appearance, structural performance, waterproofing and drainage, installation method, balcony, terrace, stair, or roof build-up, long-term maintenance, and the amount of available floor space.<\/p>\n\n\n\n

Although mounting type is often considered an architectural decision, it is equally important from a structural perspective.<\/strong> The selected system must be coordinated with the supporting substrate, slab-edge geometry, waterproofing layers, insulation build-up, required line loads, wind exposure, glass height, and available fixing depth.<\/p>\n\n\n\n

Addressing these factors early in the design process helps reduce technical risks and prevents costly changes during construction.<\/p>\n\n\n

What Is a Top-Mounted Glass Balustrade?<\/h2>\n\n\n\n

A top-mounted glass balustrade<\/strong> is fixed directly to the horizontal surface of a concrete slab, steel structure, parapet, or raised upstand. The aluminium base profile sits on top of the structure, with anchors installed vertically into the supporting substrate.<\/p>\n\n\n\n

This is one of the most commonly specified mounting methods because installation is generally straightforward. Contractors have direct access to the fixing positions from above, making installation faster and simplifying future maintenance if required.<\/p>\n\n\n\n

Top-mounted systems are commonly used for: balconies, roof terraces, external terraces, stair landings, concrete structures, steel-framed buildings.<\/p>\n\n\n\n

Where architectural finishes allow, the profile can also be recessed into the floor build-up so that only the glass remains visible above the finished surface, creating a cleaner and more minimalist appearance.<\/p>\n\n\n\n

Advantages of Top Mounting<\/h3>\n\n\n\n

Top-mounted systems are often chosen because they:provide excellent<\/strong> structural<\/strong> performance<\/strong>, simplify<\/strong> installation<\/strong>, allow<\/strong> straightforward inspection<\/strong> and maintenance<\/strong>, suit a wide range of structural substrates and can be either exposed or concealed within the floor finish.<\/p>\n\n\n\n

The main consideration is that the profile occupies part of the walking surface, which may slightly reduce usable floor space on narrow balconies or terraces.<\/strong><\/p>\n\n\n

The most appropriate system should be selected according to the required line load, glass specification, supporting structure, fixing arrangement, installation access, and applicable building regulations.<\/p>\n\n\n\n

What Is a Side-Mounted Glass Balustrade?<\/h3>\n\n\n\n

A side-mounted glass balustrade is fixed to the vertical face of a concrete slab, balcony edge, beam, stair stringer, or supporting steel structure. Instead of anchoring into the top surface, the aluminium base profile is secured horizontally into the side of the supporting structure.<\/p>\n\n\n\n

This mounting method is popular on balconies and terraces because it keeps the entire walking surface free. By moving the base profile outside the slab edge, architects can maximise usable floor space while maintaining a clean, uninterrupted finish across the balcony or terrace.<\/p>\n\n\n\n
