AAAMSA governs the performance of the aluminium system: wind load, deflection and water penetration. SAGGA governs the glass itself, through competent person sign-off, Form 4 submissions and Glazing Certificates of Conformance. A compliant project needs both.
Two different guarantees, often confused
An AAAMSA classification tells you what an aluminium system was tested to achieve: a wind-load rating, a deflection limit and a water-penetration class. It says nothing about whether the glass in it is safe. A SAGGA certificate tells you the glazing satisfies the impact and safety requirements, and says nothing about whether the frame will hold the panel in a Cape winter. The project needs the two documents together, and a supplier who can produce only one of them has answered only half the question.
The documents a professional should demand
| Document | What it proves |
|---|---|
| Glazing Certificate of Conformance | Signed by a SAGGA-registered competent person, naming the glass type, thickness, class and location of every pane we supplied. |
| AAAMSA performance submission | Wind-load, deflection and water-penetration certification for the aluminium system as installed, with the test classification quoted. |
| Form 4 submission support | Documentation pack prepared for the local authority on request, so sign-off is not held up by missing glazing evidence. |
| Fabrication drawings and cut sheets | Dimensioned drawings, glass schedules and profile cut lists issued from our Meadowdale facility against the approved revision. |
| Thermal and solar schedule | U-value and SHGC values for the specified assemblies, tabled against the climatic zone the project falls in. |
| Installation and fixing schedule | Anchor type, centres, sealant and drainage details per elevation, so the rated system is not compromised on site. |
What each body actually covers
- 01AAAMSA: wind-load testing, deflection limits for aluminium framing, water-penetration resistance and the performance classification of the system as tested.
- 02AAAMSA: the test evidence that lets a frame be specified against a wind category, rather than by a rule of thumb from the last project.
- 03SAGGA: the registration of competent persons who may sign a Glazing Certificate of Conformance.
- 04SAGGA: support for Form 4 submission to the local authority, and the technical forum that keeps the glazing trade aligned with the standards.
- 05Both: a shared interest in ensuring the system installed is the system that was tested, because that is where most compliance failures originate.
Sequence the paperwork with the programme
A Glazing Certificate of Conformance cannot be issued after the fact by somebody who was not on site. Book the competent person's inspection into the programme at the glazing stage, and require the AAAMSA submission with the shop drawings, not after the water test has failed. In practice, the projects that close out cleanly are the ones where the documents were named in the order.
Why this matters commercially, not just legally
A withheld sign-off stops a tenant from occupying, delays a payment and turns an architect into an adversary. A fenestration package that arrives with its certificate, its performance submission and its drawing revision control in place is worth more to a main contractor than a lower price from a supplier who has never been asked for either document.
