Preparing the Installation Site for Glass Balustrades

Start with an accurate on-site measurement

Glass railings are made to measure, so the first step is a careful site measurement. The factory team or installer measures the run length, height, and the exact position of slabs, edges and openings. Measurements should be taken after the finishing of the slab edge, because a few millimeters of render or tile can change the fit.

Check that the measured surfaces are straight and square. Mark any corners, recesses or irregular edges so they appear on the drawing before production starts.

Prepare the base and fixing points

The base must be sound enough to carry the fixings and the load the railing is designed for. Before installation, check the following:

• The concrete or steel base is complete, cured and free of loose material.
• Fixing positions are clear of rebar, cables and pipes.
• Surfaces are level enough that the glass panels will sit evenly.
• Any sealing or waterproofing that must go under or around the base is finished first.

Where the base is stone or tile, confirm with the engineer which fixing method is suitable.

Plan the order of works with the other trades

Glass railings are usually installed late in the job, so timing matters. Agree on a schedule that places the installation after heavy wet work, plastering and tiling are complete, but before the area is handed to finishing trades that could damage the glass.

Store glass and metal parts flat, dry and protected. Keep the access route clear so panels can be carried without being cut across the site.

Understand the production and finishing stages

Once the measurements and drawing are approved, the work goes to the factory. Steel components are finished by hot-dip galvanizing or powder coating, which takes time and must be built into the schedule. Stainless steel and aluminum parts are prepared to match the chosen finish.

Avoid changing the design once production starts. Late changes to height, glass type or fixing style can delay the whole order.

Confirm safety requirements before installation

Railings must meet the relevant Israeli standard (SI 1142) for height, infill spacing and resistance to load. The exact values depend on the project, so confirm them with the structural or safety engineer before ordering. Do not assume a figure from another project.

On site, make sure edges are protected while work is in progress and that the installation area is barricaded for passers-by.

Hand over clearly to the installer

Give the installer the approved drawing, the written specification, the measurement sheet and a site contact. Confirm access, parking for the delivery vehicle, and who will sign off the installed railing.

• Approved drawing with dimensions and fixing details
• Access route and loading area
• Site contact and working hours
• Final inspection and handover checklist

Frequently asked questions

When should the site be measured for glass railings?

Measure once the slab edge and surrounding finishes are complete, as small changes in render or tile affect the fit. Measurements are then confirmed before the order goes into production.

Who checks the base before the installer arrives?

The general contractor is responsible for confirming that the base is level, sound and clear of obstacles. The installer should review the site on arrival and report any issues before fixing begins.

Can glass railings be installed on tile or stone?

Yes, but the fixing method must suit the material and the load. Confirm the approach with the engineer before installation so the base is not damaged.

How long does production take after approval?

Production time depends on the design and finishing, and galvanizing or powder coating add time. Ask the factory for the current schedule when you approve the drawing.

Common mistakes to avoid

The most common problems are measuring before finishes are complete and changing the design after production has started. Both lead to delays and fitting problems on site.

Our recommendation

Freeze the drawing and measurements in writing before production begins, and walk the site with the installer one week before the scheduled date to catch any base or access issues early.

Summary

Good preparation means accurate measurements, a sound and level base, a coordinated schedule and clear handover documents, so the glass railing goes in smoothly.
