Safety Glass Partitions for Stairwells and Balconies

t423-8

A safety glass partition for a stairwell or balcony is normally made from laminated or tempered glass, which holds together or breaks into small pieces when damaged. The right choice depends on the glass build-up, the fixing method and the height and location of the partition. Your engineer should confirm the final specification against the applicable standards before production.

Why building committees choose safety glass for partitions

Glass partitions in stairwells and on balconies let light through and keep views open, which is why many building committees consider them for shared areas. The concern is always safety: people lean on these surfaces, children play near them and accidental impacts happen. Safety glass is designed to reduce the risk of sharp injuries, so it is the standard starting point for any glass partition in a residential or shared building.

Before deciding, a committee should agree on the main goals: visibility, durability, maintenance and budget in the broader sense of total lifetime value. Writing these goals down makes it easier to compare options with the manufacturer and the engineer.

Laminated glass: the layered option

Laminated glass is made of two or more glass sheets bonded with a plastic interlayer. When it breaks, the fragments tend to stay attached to the interlayer, so the opening stays closed and the risk of falling pieces is reduced. It is often chosen for stairwell partitions and for balcony infill where continued protection after an impact matters.

Tempered glass: strength and fragmentation

Tempered glass is heat-treated to be stronger than standard annealed glass. When it breaks, it shatters into small, relatively blunt pieces rather than long sharp shards. It is a common choice for frameless glass panels and for applications where high strength and a clean, uninterrupted look are important.

Because tempered glass cannot be cut or drilled after treatment, all dimensions and fixing holes must be defined precisely at the measuring stage. This is one reason on-site measurement is part of our standard process.

Frames, fixings and handrail integration

The glass is only as safe as the system holding it. Partitions may be framed in steel or aluminum, or they may be frameless with glass clamped to posts or fixed with point connectors. The choice affects both appearance and load performance. For stairwell and balcony barriers, the handrail is often integrated with the glass or mounted above it, and the connection must be designed to carry the expected forces.

Checking compliance with standards

In Israel, railings and guarding are commonly assessed against the national railing standard, SI 1142, among other requirements. The standard covers aspects such as height, infill and loading. Exact numerical values depend on the building and the use of the space, so they should be confirmed with the project engineer rather than taken from a general article.

We recommend that the committee request a written specification that lists the glass type and build-up, thickness, frame material, fixing method and the standard referenced. Keeping this document with the building records simplifies future inspections and maintenance.

The approval process from inquiry to installation

A typical project begins with an inquiry supported by photos of the stairwell or balcony. We then arrange an on-site measurement to capture the real dimensions, which often differ from drawings. Based on the measurement we prepare a drawing and a written specification for the committee to review and approve.

After approval, the partition is produced in our factory at 37 Rival Street, Tel Aviv, and finished as required before installation. Clear approval steps at the beginning help avoid changes once production has started.

Frequently asked questions

Is laminated or tempered glass better for a stairwell partition?

Neither is universally better. Laminated glass keeps broken pieces bonded to the interlayer, while tempered glass offers high strength and breaks into small blunt fragments. The best choice depends on the location, fixing method and the engineer's specification.

Can safety glass be cut on site after it is made?

Tempered glass cannot be cut or drilled once treated, so dimensions and holes must be defined before production. Laminated glass is also produced to size, which is why on-site measurement comes first.

Which standard applies to glass balcony and stair barriers in Israel?

Railings and guarding are commonly assessed against SI 1142 among other requirements. Exact values should be confirmed with the project engineer for your specific building.

What should a building committee ask for before approving a glass partition?

Request a written specification covering glass type and thickness, frame material, fixing method, corrosion protection and the referenced standard. Keeping this document on file helps with future inspections and maintenance.

Common mistakes to avoid

Committees often choose glass by appearance alone, or skip the on-site measurement and approve drawings that do not match the real opening. Both can lead to rework and a partition that does not meet the intended safety requirements.

Our recommendation

Ask the engineer to confirm the glass build-up, fixing method and handrail connection before ordering, and insist on a written specification that cites the standard. Measuring on site before production prevents costly corrections later.

Summary

Laminated and tempered safety glass are the main options for stairwell and balcony partitions, and the right choice depends on location, fixing and engineer approval. A clear written specification keeps the project safe and easy to maintain.
