Tempered Safety Glass for Partitions and Display Cases

t433-12

Tempered safety glass is heat-treated glass that breaks into small, blunt pieces instead of sharp shards, which is why it is commonly specified for partitions, glass vitrines and other areas where people may come into contact with the glass. Whether a specific installation must use it depends on its location, height and how people move around it, so the final choice should be confirmed with the engineer or architect.

What Makes Glass Tempered

Tempered glass is made by heating standard float glass to a high temperature and then cooling it quickly. This process builds internal stress into the surface, which makes the glass several times stronger than ordinary glass of the same thickness.

The key safety feature is how it fails. When tempered glass breaks, it shatters into small, relatively blunt granules rather than long, dangerous shards. Because the pieces are cut once the glass has been tempered, the shape of a tempered panel cannot be altered afterward, so all cutting, drilling and edge work must be completed beforehand.

Where Safety Glass Is Typically Used

Tempered safety glass is often chosen for interior partitions, glass display cases, shop fronts, shower enclosures and balcony or stair glass. Any place where a person could walk into the glass or fall against it is a candidate for safety glass.

Partitions Versus Display Cases

Partitions are usually tall, sometimes spanning floor to ceiling, and they must withstand accidental impact from people and objects. Display cases are typically lower and more exposed to handling, with shelves and glass edges that need to hold weight and resist chipping.

In both cases, the glass thickness, edge finish and fixing system work together. A well-chosen panel can still be let down by poor hardware, so the whole assembly should be considered, not just the glass itself.

Edges, Fixings and Finishing

Edges of tempered glass are normally polished or seamed so they are smooth to the touch. Holes for fixings and hinges must be made before tempering, and the position and size of each hole should be checked carefully during measurement.

Fixing systems such as clamps, patch fittings, channels and spacers hold the glass in place. Their material and tightening method matter as much as the glass, and they should suit the thickness and expected loads of the panel.

Safety Standards and Engineering Checks

Israeli requirements for glazing and railings are set out in official standards, including SI 1142 for railings. This article does not list exact values, because thickness, height and load requirements depend on the specific project and must be verified by a qualified engineer or architect.

Before production, ask whether the building or local rules require safety glass in the proposed location and what thickness is appropriate for the span and fixing method.

Planning and Ordering Your Glass Work

Good results start with accurate information. Share photos of the space, the intended use, the height and width of the opening, and any special requirements such as privacy or wall fixings. An on-site measurement helps confirm the final dimensions before anything is produced.

After measuring, a drawing and written specification are prepared for your approval. Once approved, the glass is produced to size in the factory, finished and then installed, so decisions made early save time and avoid costly changes later.

Frequently asked questions

Can tempered glass be cut after it is made?

No, tempered glass cannot be cut, drilled or reshaped after tempering without breaking it. All cuts, holes and edge work must be completed before the heat treatment.

Is tempered glass the same as laminated glass?

No, they are different products. Tempered glass shatters into small pieces, while laminated glass holds its fragments together with an interlayer, and the right choice depends on the application.

Does safety glass need to be marked?

Safety glass is often marked with a permanent stamp in one corner to show it has been tempered. Check with your engineer or inspector if you need documentation for a specific project.

Who decides if my partition needs safety glass?

The final decision should be made with your architect, engineer or the relevant authority, since requirements depend on location, height and use. We can help you prepare the measurements and options for that discussion.

Common mistakes to avoid

A common mistake is ordering glass from measurements taken without checking the fixing points, which can lead to panels that do not fit. Another is choosing the glass thickness or fixing hardware without confirming the load and safety requirements for the location.

Our recommendation

Before ordering, have the location, height and fixing method confirmed by your engineer or architect, and request an on-site measurement so the glass is produced to the exact dimensions. Ask for a written specification and drawing to approve before production begins.

Summary

Tempered safety glass offers strength and safer breakage for partitions and display cases, but the right thickness and fixings depend on the specific installation. Confirm the requirements with a qualified professional and measure carefully before ordering.
