Glazing certificates are the paperwork that shows what glass was supplied and installed, and who took responsibility for it.
A glazing certificate confirms that a specific glazing installation meets the applicable requirements — it relates to the actual work, not a supplier’s membership of an association.
On many projects — especially commercial ones — someone will ask for a glazing certificate. This guide explains what such a certificate is, what it confirms, who issues it, and how the industry certification framework works — without overstating anything, because certification relates to specific work and specific requirements.
What a glazing certificate confirms: glazing certificates
A glazing certificate is essentially a record that the glazing in a project meets the applicable requirements. In practice that usually means two things: that the correct glass was specified and supplied for its positions (for example, safety glazing where it is needed), and that it was installed correctly, in line with good practice such as SANS 10137. It is a confirmation about the actual installation, not a generic badge.
The role of the installer: glazing certificates
Because a certificate is about the work that was carried out, the installer is central to it. The person who supplied and installed the glazing is best placed to confirm what glass went where and that it was fitted correctly — which is why accurate product and installation records matter. Keeping track of the glass specification, its safety marking and the installation detail is what makes a meaningful certificate possible.
The role of SAGGA and industry frameworks: glazing certificates
South Africa has an industry certification framework: SAGGA (the South African Glass & Glazing Association, affiliated with AAAMSA) operates a glazing certification procedure through accredited installers, and a SAGGA Certificate of Conformance may be obtained for safety glazing. This framework is valuable and widely recognised. Importantly, though, membership of SAGGA does not automatically certify all work — a certificate is issued for a specific installation that has been done and, where applicable, inspected against the procedure. Membership and certification are related but separate things.
What a customer or project manager should ask for: glazing certificates
If you are a homeowner, builder, architect or project manager, it is reasonable to ask for: confirmation of the glass specification supplied (with its safety marking), and, where a certificate is required, a glazing certificate for the installation. For safety-critical or commercial work, ask early who will issue it and under what framework. If it is unclear whether a certificate applies, that is a prompt to confirm against the applicable requirements — see when a glazing certificate is required.
What a glazing certificate means for you: glazing certificates
For a customer or project manager, a glazing certificate turns ‘it complies’ into evidence: the right glass, correctly installed. Ask early who will issue the glazing certificate and under what framework, and keep records of the glass specification supplied.

What this means in practice on a real project: glazing certificates
Reading about glazing certificate is one thing; evidencing it on a live project is another. In our experience the difficulties almost never come from the requirement itself — they come from nobody having decided, early enough, who is responsible for the decision and who will produce the paperwork at the end. That question is worth settling at specification stage rather than at handover.
Decide who is responsible before the glass is ordered: glazing certificates
On a supply-only order the responsibilities split. The supplier is accountable for manufacturing what was specified and for describing accurately what has been supplied. The party doing the installing is accountable for how the unit is fitted, packed and sealed. Whoever signs off the completed work is accountable for confirming that the installed result is appropriate for the application. Those are three different roles, and on smaller projects they are often three different companies, which is exactly how gaps appear.
Ask for the documentation while the job is still open
Whatever record your project needs is far easier to obtain during the contract than a year later. Keep the order confirmation showing what was supplied, keep the delivery documentation, and photograph the glass markings before the units are installed and the edges are covered by beading. Those three items answer most later questions about what was actually fitted, and they cost nothing to collect at the time.
Where Coetz™ fits in
Coetz™ supplies aluminium windows and doors glazed as standard with 6.38 mm clear laminated safety glass, and states on the order what has been supplied. Aluminium windows and doors are supplied only; automatic door systems are installed and serviced by our team. We are glad to confirm in writing what a given order contains, which is usually what a contractor or building inspector actually needs from the supplier.
An important limit on this page. The summary above is general guidance, not a compliance opinion, and it is not a substitute for the published standard or for professional advice. Requirements vary with the application, the building and the specifics of the installation. Where a decision about glazing certificate carries safety or regulatory consequences, work from the current published text and engage a suitably qualified competent person for your project.
Requesting the documentation: glazing certificates
Ask for glazing certificates while the contract is still open rather than a year later, when the contractor has demobilised and the paperwork is harder to trace. Keep the order confirmation showing what was supplied, the delivery documentation, and a photograph of the glass markings before the beading covers the edges. Those three records answer most later questions, and together they are usually what a building inspector or an incoming owner is actually asking for when they request glazing certificates. This page is general guidance, not a compliance opinion.
