What is a glass balustrade?

A glass balustrade is a guarding system formed from toughened-laminated glass panels fixed along the open edge of a balcony, terrace, stair, landing or mezzanine. Unlike metal or timber railings, a frameless glass balustrade presents an uninterrupted sight line — the barrier reads as glass rather than posts and rails, which suits contemporary extensions, roof terraces and glazed openings.

How a frameless glass balustrade works

At Vant Glass, balustrades are made to measure in Britain. You specify the total run length, the glass height and the fixing method; we calculate equal panel widths across the run (typically up to around 1300mm per panel) and manufacture each pane to the millimetre.

Panels are held by one of three mounting systems:

• Base channel — panels slot into a recessed aluminium channel along the floor edge. This gives the cleanest frameless appearance with no visible clamps at the base.
• Standoff spigots — discreet stainless-steel clamps fix each panel at the base. Spigots suit decks and slabs where a channel recess is impractical.
• Posts — vertical posts between panels. The most traditional and economical option, with wider sight lines at each post.

An optional top handrail — slimline or round — can be added where you want a continuous handhold or where building control expects one on a frameless system.

Glass specification

Balustrade panels use toughened-laminated safety glass as standard. Toughening increases impact resistance; lamination bonds the panes with an interlayer so that if a panel is broken, fragments stay adhered rather than falling. Thickness is selected to suit span, height and mounting — common options include 12mm, 15mm, 17.5mm and 21.5mm builds.

Clear glass is the default; tinted and frosted finishes are available where privacy or solar gain matters. Hardware is offered in brushed steel, polished chrome or matt black to match other ironmongery on the project.

Typical heights and applications

For external balconies and terraces, 1100mm is the usual guard height in domestic work — the dimension most homeowners and designers specify. Glass height can be set between roughly 700mm and 1200mm depending on the guarding requirement and fixing detail; confirm the exact height with your designer or building control before ordering.

Glass balustrades are specified wherever a level change needs guarding without blocking views:

• First-floor balconies and Juliet-style openings
• Roof terraces and garden-level decks
• Internal landings, galleries and mezzanines
• External stairs where a glass edge guard is preferred

What to confirm before ordering

1. Total run length — measure each straight side; note L- or U-shaped corners separately.
2. Glass height — usually 1100mm for balconies; check Approved Document K if unsure.
3. Fixing system — channel, spigots or posts; confirm the substrate can accept the chosen detail.
4. Handrail — whether you want none, slimline or round.
5. Building control — guarding is notifiable work on many projects; agree the specification early.

A well-specified glass balustrade delivers safety and transparency in one assembly. Panels are factory-made to your dimensions — there is no cutting toughened glass on site after delivery.
