Top-Mounted vs. Spigot Systems: Which Glass Balustrade is Right for Your NI Home?
When planning a renovation in Northern Ireland—whether it’s a coastal balcony in Portrush or a modern patio in Castlereagh—the "how" is just as important as the "wow."
At Glass Balustrades Ireland, we focus on high-performance, top-mounted systems that sit securely on your finished floor. But should you go for a continuous base channel or individual spigots? In 2026, both are trending, but they offer very different aesthetics for the NI homeowner.
The Sleek Base Channel (The Frameless Favorite)
If you want the "all-glass" look you see in modern Belfast penthouses, the top-mounted base channel is the winner.
The Look: A continuous aluminum or stainless steel U-channel that holds the glass from the bottom.
The Benefit: It creates a solid, unbroken line. It’s perfect for internal landings where you want a seamless transition or for external balconies where you want a high-end, architectural finish.
NI Weather Proof: Because the channel is solid, it provides an excellent seal against the wind, making your outdoor area much more comfortable during a typical Ulster breeze.
The Spigot System (The "Mini-Post" Modernist)
If you prefer a bit of "industrial flair," glass spigots (sometimes called mini-posts) are the way to go.
The Look: Small, heavy-duty stainless steel clamps that hold each glass panel in place, leaving a small gap between the glass and the floor.
The Benefit: Spigots are incredibly easy to level on slightly uneven surfaces. They allow for better drainage on patios, as rainwater can flow under the glass rather than pooling against a channel.
Versatility: These are a favorite for DIYers in areas like Bangor and Lisburn because they require less precision during the initial floor prep compared to a full-length channel.
Staying Compliant with Technical Booklet H
Safety is non-negotiable. Whether you choose a channel or spigots, your installation must meet Northern Ireland’s Technical Booklet H requirements:
Internal Guards: Must be at least 900mm high.
External Balconies: Must reach a minimum of 1100mm.
The 100mm Rule: Our systems ensure that no gap—between panels or under the glass—is large enough for a 100mm sphere to pass through, keeping kids and pets safe.
