A Guide to Frameless Glass Balustrades – The 3 types and their applications

1. What Are Frameless Glass Balustrades?

Frameless glass balustrades are barriers made from thick, tempered glass panels that are installed without the need for metal frames. The absence of a frame allows for clear, uninterrupted views, making these balustrades popular in settings where aesthetics and visibility are key considerations.

Frameless glass balustrades are commonly used in:

  • Balconies: To provide safety without compromising the view.
  • Staircases: To add a contemporary touch while ensuring safety.
  • Pool Areas: To create a safe boundary around the pool without detracting from the surrounding landscape.
  • Terraces and Decks: To maintain an open and airy feel while providing a safety barrier.

2. 3 Types of Frameless Glass Balustrades

1. Cut Into Slab Balustrades

Cut Into Slab balustrades are an innovative and minimalist solution. In this installation method, the glass panels are inserted into a slot cut directly into the slab or concrete surface. This approach allows the glass to be embedded into the floor, giving the impression that the glass is emerging seamlessly from the surface.

Advantages:

  • Sleek and Minimalist Design: The lack of visible fixings enhances the seamless appearance of the balustrade.
  • Stability: The glass panels are firmly anchored into the slab, providing robust structural integrity.
  • Uninterrupted Views: Since the glass is embedded directly into the floor, there are no visible mounting components to obstruct the view.

2. Top Mount Balustrades

Top Mount balustrades, also known as base-mounted balustrades, are one of the most popular choices for frameless glass installations. In this method, the glass panels are mounted on top of the surface using a continuous channel or individual spigots (metal clamps). The glass is secured by either clamping it in place or fixing it with structural adhesives.

Advantages:

  • Versatility: Can be installed on various surfaces, including concrete, timber, and steel.
  • Ease of Installation: The installation process is relatively straightforward and less invasive compared to Cut Into Slab balustrades.
  • Adjustability: The glass panels can be easily aligned and adjusted during installation to ensure a perfect fit.

3. Side Mount Balustrades

Side Mount balustrades, also known as fascia-mounted balustrades, involve attaching the glass panels to the side of the surface, such as the edge of a balcony or staircase. This method is ideal for situations where floor space is limited or when you want to maintain a completely flush floor surface.

Advantages:

  • Space-Saving: Since the glass is mounted on the side, it maximizes usable floor space.
  • Clean Lines: The side-mounted hardware is often less visible, contributing to a cleaner, more streamlined appearance.
  • Flexibility: Suitable for both indoor and outdoor applications, including balconies, terraces, and staircases.

3. Balustrade Certificate of Compliance


Clear View Frameless issues a Certificate of Compliance for balustrades, ensuring they meet the stringent SANS 10400 and 10160 regulations. This certification is crucial for securing occupancy approval in South Africa, as it confirms that your balustrades adhere to all safety and structural standards.

Adhering to these requirements is essential because balustrades play a vital role in preventing accidents and ensuring the safety of occupants, particularly in multi-story buildings. Non-compliance can lead to severe legal and financial consequences, including fines, delays in project completion, and potential harm to residents or visitors. By meeting these regulations, you protect not only the structural integrity of the building but also the well-being of everyone who uses the space.


Frameless glass balustrades offer a perfect blend of safety and style. Whether you opt for the sleek Cut Into Slab method, the versatile Top Mount option, or the space-saving Side Mount approach, these balustrades are sure to elevate the look of your property while providing the necessary safety.

By understanding the different types and installation methods, you can make an informed decision that aligns with your design vision and functional needs. Whatever you choose, frameless glass balustrades are a timeless investment that adds value and beauty to any space.
