How to Prepare a Technical Brief for Custom Glass Orders

Define the purpose and location of the glasswork

Start by stating what the glass element will do. A vitrine must display objects safely, while a partition may separate rooms, control sound, or let light pass between spaces. Name the exact location, such as a shop floor, office lobby, or residential interior, because the use determines the glass type, edge treatment and required strength.

Also note who will use the space and how often. High-traffic areas and areas near children or doors need different safety considerations, and this information helps the fabricator recommend the right solution.

Take accurate site measurements

Measurements are the most important part of the brief. Measure width, height and depth at several points, because walls, floors and ceilings are rarely perfectly straight or level. Record the smallest and largest readings and mark them on a sketch.

• Opening or fixing area dimensions at top, middle and bottom
• Floor level variations and wall plumbness
• Obstacles such as skirting, pipes, switches and door swings

Where possible, arrange an on-site measurement by the fabricator before final drawings are approved.

Specify glass type, thickness and finish

State the glass type you need, such as clear, tinted, laminated, or frosted, and whether it must be tempered for safety. Include the thickness if you know it, but let the fabricator confirm it against the span, the load and the applicable safety requirements.

Describe the finish of visible edges, the type of polishing, and any surface treatments. Provide a sample or a reference image wherever colour or transparency matters, since screens and printed photos can show colours differently from the actual glass.

Describe the frame, fixing and hardware

Explain how the glass should be held. Some vitrines use a minimal frame, others a full aluminum or stainless steel profile, and partitions may use floor and ceiling channels, spider fittings or point fixings. Each method affects the required dimensions and the amount of clearance needed.

List the hardware you expect, including hinges, locks, handles, sliding systems and seals. Indicate the finish you prefer, such as brushed stainless steel or powder-coated colour, and any colour codes to match existing elements.

Attach drawings, photos and written notes

A clear drawing is worth more than a long description. Include a plan view, an elevation and, where relevant, a section showing the thickness and fixing details. Mark all dimensions in one unit system and label every part.

• Dimensioned drawings with a north or orientation note if relevant
• Photos of the existing location from several angles
• A short written list of requirements and must-have features

Keep notes concise and consistent with the drawings, because contradictions are a common cause of errors.

Confirm approvals, timing and installation conditions

Before sending the brief, confirm who approves the drawings and who signs off the final design. Note any deadlines tied to building works, since glass should not be installed before the surrounding walls, floors and finishes are ready.

Finally, describe the installation access: lift availability, stairs, protective covering needs and working hours in the building. Clear conditions help the fabricator plan transport and avoid delays on site.

Frequently asked questions

Who should provide the measurements for a custom glass order?

Ideally the fabricator measures on site or a qualified person measures using the same method for all points. Measurements taken from old plans are often inaccurate and should be verified before production.

Do I need to include a drawing if I already have photos?

Yes, photos show the look, but a dimensioned drawing defines the exact sizes and fixings. Use both together for the clearest brief.

Can I change the glass type after the order is approved?

Changes are possible but may affect the design, the schedule and the approval process. Raise any doubts before the drawings are signed off.

What if the wall or floor is not level?

Note the variations on your sketch and let the fabricator plan the fixing and any necessary adjustment. Hidden irregularities are a frequent source of rework.

Common mistakes to avoid

Sending a brief with a single measurement or unlabelled drawings is the most common error, which leads to fit problems. Leaving out installation access details can also cause costly delays on the day of delivery.

Our recommendation

Measure at three points on each dimension, mark the smallest reading as the working size, and have the final drawing signed before production begins. This simple habit prevents most glass fitting problems.

Summary

A good custom glass order brief combines accurate measurements, clear drawings, defined glass and hardware choices, and confirmed installation conditions. Preparing it carefully saves time and avoids rework.
