Glass Balustrades for Corner Balconies With Two Open Sides

t342-49

A corner balcony with two open sides needs continuous edge protection along both exposed edges, and frameless or semi-frameless glass balustrades are a common way to achieve it while keeping the view open. The glass panels are fixed to a steel or aluminum base or to the slab edge, with corner posts or corner glass clamps to join the two runs. Exact dimensions, glass thickness and fixing details are confirmed by the engineer for each balcony.

Why corner balconies need a different approach

A corner balcony is open on two sides, so the railing has to run continuously around the corner without gaps that could become a hazard. Unlike a straight balcony, the wind load often hits the corner from two directions, and the joint where the two runs meet carries extra stress.

Residents usually want a clear view over the city or the sea, which makes glass a natural choice. The challenge is planning the corner joint and the fixings from the start so the railing looks light and stays firmly anchored.

Frameless, semi-frameless or post-supported glass

There are several common ways to build a glass railing for a corner:

Frameless glass
with glass clamps or a base channel fixed to the slab edge
Semi-frameless
with a slim top handrail and glass panels between posts
Post-supported
with steel or aluminum posts at each corner and intermediate points

Each option suits different balcony widths, slab conditions and budgets. We discuss the choice with you on site.

Handling the corner joint

The corner is where most of the design effort goes. A common solution is a corner post or a pair of glass clamps that hold the two glass runs at a set angle, typically close to ninety degrees. The joint should be stable, neat and easy to inspect.

Where the balcony has an irregular angle or a column in the corner, the corner detail is adjusted to the actual geometry. Precise on-site measurement is the basis for a clean joint.

Safety, height and standards

Railings must meet height and load requirements set by Israeli building regulations. The Israeli railing standard SI 1142 is the reference point for general design, but exact values such as height, baluster spacing and glass specification are checked with the engineer for your specific balcony and building.

Laminated safety glass is normally specified for balustrades, and the handrail and fixings must be designed for the expected loads.

Our process: from measurement to installation

Our work follows a clear sequence. You send an inquiry with photos, we measure the balcony on site, and we prepare a drawing and a written specification. After you approve the design, we produce the steel or aluminum components in our factory on Rival Street in Tel Aviv, finish them by hot-dip galvanizing or powder coating, and install them on site.

Doing the measurement and drawing first avoids surprises, because every corner is slightly different.

Maintenance and keeping the glass clear

Glass balustrades need little maintenance. Clean the glass with water and a soft cloth, and avoid abrasive pads that scratch the surface. Check the fixings and the corner joint from time to time, especially after strong storms.

Clean glass regularly to keep the view clear
Look for loose clamps or screws each season
Keep drainage paths on the balcony clear of debris

Frequently asked questions

Can a corner balcony railing be made fully frameless?

Yes, in many cases a frameless corner is possible using corner clamps and a suitable base. Whether it works depends on the slab, the balcony geometry and the loads, which we check on site.

Do we need an engineer for a glass balustrade?

For most balcony railings, an engineer confirms the design, glass thickness and fixings. We coordinate the details with your engineer so the drawing meets the requirements.

Is the glass safe if it breaks?

Laminated safety glass is normally used, so the panel holds together if it cracks. This is a standard specification for balustrades.

How do I start a project with you?

Send us photos of the balcony and a few measurements or a description of the two open sides. We then arrange an on-site visit to measure and advise.

Common mistakes to avoid

Choosing the glass type or corner detail before measuring the balcony often leads to costly changes. Skipping the engineer's check on height and fixings is another common error that can cause problems at inspection.

Our recommendation

Measure both open edges carefully, note any columns or irregular corners, and decide on the corner detail early. Ask for a written drawing before production starts, so you can confirm the design and the fixings.

Summary

A glass balustrade on a corner balcony with two open sides works best when the corner joint, fixings and glass specification are planned from the start, based on accurate on-site measurement.
