Can I Install Blinds on My Apartment Balcony?
Yes, but not just any outdoor blind.
Above ground level (or the level immediately above ground), the National Construction Code requires external blinds on multi-storey buildings to be made from non-combustible materials — unless the specific blind system has been independently fire tested and shown not to spread fire. Most fabric and PVC blinds haven't been tested this way, which is why so many apartment buildings restrict balcony blinds altogether. A tested system changes that.
Why are apartment balconies held to a different standard than a house?
A house is one storey (or close to it), so a blind that catches fire mostly stays a problem for that house. A balcony blind on a 12-storey building is different: if it can catch fire and pass flame or burning debris upward, it becomes a path for a fire to climb the outside of the building, past the floors that fire brigades and sprinklers are designed to contain it on. That's the risk the National Construction Code (NCC) is managing.
Under NCC Volume One (Building Code of Australia) 2022, Clause C2D14 (Ancillary Elements), external blinds are required to be non-combustible, unless they're installed at ground level or on the level immediately above ground. NCC Volume One covers Class 2 buildings — apartments — along with other multi-residential and commercial building classes, so this clause is exactly the one that governs a blind on your third-floor balcony.
What's the “900mm rule” people mention?
Where a combustible blind system is used on multiple storeys of the same building, the default expectation is that installations can't run as one continuous flammable surface up the face of the building — there needs to be a 900mm vertical clearance between the blind on one level and the blind on the level above or below it. On a stack of balconies that's awkward: it either eats into your outdoor space or leaves an ugly 900mm gap in the middle of an otherwise closed-in balcony.
The clearance rule exists because nobody had shown that a particular blind fabric wouldn't pass fire from one storey to the next. Once that's actually tested, the calculus changes.
Is there a tested and engineer-assessed system for apartment balconies?
Yes. Vistaweave 95 mesh fabric, installed in the Ziptrak track-guided frame system, has been independently fire tested and assessed specifically for this use case — a blind mounted about 100mm behind a glass balustrade on a multi-storey balcony.
The fabric itself was tested by AWTA Product Testing (a NATA-accredited lab) in two separate batches:
- AS 1530.2-1993 (Flammability of Materials) — tested 12 December 2018, report 18-007149
- AS/NZS 1530.3-1999 (Ignitability, Flame Propagation, Heat Release and Smoke Release) — tested 14 January 2019, report 18-007472
Those results were then combined with a full-scale, simulated-balcony fire test to ISO 13785-1:2002, carried out on the complete Ziptrak + Vistaweave 95 installation (aluminium headbox, aluminium track-guided side channels, and fabric — deployed in working order). The whole package is documented in a Fire Assessment Report (IGNL-8291-13R I01R01) prepared by IGNIS Labs, a chartered fire engineering practice, issued 12 May 2025 and valid until 29 April 2029, authorised by Benjamin Hughes-Brown, a Chartered Professional Engineer (Fire Safety).
What did the fire test actually involve?
The test rig simulated a real balcony installation: the Ziptrak system was mounted with its face set back a minimum of 100mm behind a glass balustrade at least 600mm high, fixed above a rebated slab, with the fire source below — the same geometry as a blind hung inside a balcony's glass railing.
A gas sandbox burner was used to expose the installation to fire in two stages:
- Installation test — the burner run at 100kW for 30 minutes, with the flame directed at the balustrade below the blind (not the fabric directly), to see whether fire below the balcony could spread up the face of the installed system.
- Direct flame impact test — the burner then moved to sit directly against the Vistaweave fabric itself, run at 100kW for 10 minutes, 300kW for 10 minutes and 400kW for 5 minutes (25 minutes total), to see how the material behaves under a much more severe, direct fire exposure than it would realistically face.
What did the test find?
During the installation test, flame spread up the face of the system was tracked at 0.5m, 1.0m, 1.5m and 2.0m marks, and at the top of the specimen. The blind did not ignite at any of these points — the only flames present were from the burner itself. The glass balustrade cracked at the 13-minute mark under 300kW but did not fail.
During the direct flame impact test, the Vistaweave fabric reacted to the fire — it's a coated polyester fabric, not a non-combustible material, so it does thermally degrade under direct flame. But the report records that it shrank back and away from the fire rather than sustaining combustion or spreading it, produced no flaming debris, and the nylon side-guide inserts, which briefly flamed, self-extinguished shortly after the main fire was put out.
Ignis Labs' conclusion: “the Ziptrak external blind, incorporating the Vistaweave material has demonstrated to not ignite or spread fire… [and] does not present an undue risk of fire spread.”

Vistaweave 95 is a basketweave, PVC-coated polyester fabric (roughly 30% polyester / 70% PVC by AWTA's testing), tested at approximately 530–545gsm across the two independent 2018–19 batches.
Does this mean the 900mm clearance isn't needed?
For this specific combination, no — that's the headline finding. Ignis Labs' assessment states plainly that the ISO 13785-1 results “definitively eliminate the need for the previously mandated 900mm vertical clearance between blind installations” when using the Ziptrak and Vistaweave 95 system. In other words, you can run this particular blind on stacked balconies, floor after floor, without leaving a 900mm combustible-material-free strip between each one.
This applies to the Ziptrak + Vistaweave 95 combination specifically — it's not a general statement about outdoor blinds, and it doesn't extend to other fabrics or frame systems that haven't been through the same testing.
What balustrades does this work with?
The physical fire test used a glass balustrade, deliberately chosen as the worst-case option among the balustrade types the report evaluates as suitable. Based on that test, Ignis Labs' report treats the following as acceptable, provided the balustrade is at least 600mm high and the blind sits with a minimum 100mm setback from it:
- Glass balustrades
- Masonry or concrete balustrades
- Metal balustrades
- Stainless steel cable balustrades
Is Vistaweave 95 “fireproof”?
No, and it's worth being precise here: Vistaweave 95 is a PVC-coated fabric, not a non-combustible material, and it will degrade under direct flame. What the testing shows is that it doesn't sustain combustion, doesn't spread fire beyond where it's directly exposed, and doesn't drop flaming debris — which is the specific fire behaviour the NCC's balcony provisions are concerned with. That's a meaningfully different (and verified) claim from “fireproof,” and it's the one the Fire Assessment Report actually makes.
Do I still need approval from my strata, builder or building certifier?
Yes. A Fire Assessment Report like this one is what's known as an Alternative Solution or Performance Solution pathway under the NCC — evidence a professional fire engineer can rely on to demonstrate compliance, rather than a blanket product certificate that overrides your building's own approval process. Ignis Labs' own report is explicit that it doesn't guarantee sign-off from every building authority, and that it needs to be read alongside your building's specific plans and construction.
In practice, that means:
- Check with your owners corporation / body corporate before installing anything on a shared building facade — most apartment buildings have rules about balcony alterations regardless of fire compliance.
- If your building surveyor or certifier needs evidence the blind won't compromise the building's fire compliance, this report is what your installer should hand them.
- The report's approval is tied to the tested installation geometry — a 600mm-plus balustrade, roughly 100mm blind setback, and the specific Ziptrak + Vistaweave 95 combination. A materially different setup may need its own assessment.
- The report is valid until 29 April 2029; for anything installed after that, check that it (or its successor) is still current.
How do I get a compliant blind installed on my apartment balcony?
- Confirm your balcony's level. Ground floor and the level immediately above ground generally don't need a fire-tested system at all — this is specifically for everything above that.
- Check with your strata/body corporate about balcony alterations before ordering anything.
- Choose a tested combination — Ziptrak track-guided frame with Vistaweave 95 mesh is the system this article is based on.
- Pass the report along if your certifier, builder or strata committee asks for evidence of fire compliance.
- Use a qualified installer who fixes the blind to the tested geometry — balustrade height and blind setback matter to whether the report actually covers your installation.
When you order, the Ziptrak® form will ask you about fit type, head option, bottom rail and weatherstrip — choices that matter more on a balcony than most places. Ziptrak options explained covers each one.

Can I put any outdoor blind on my apartment balcony?
Not above ground level or the first floor. The NCC requires external blinds on multi-storey buildings to be non-combustible unless the specific system has passed fire testing showing it won't spread flame between levels. Check what your blind is made from and whether it's been tested before installing above those levels.
What is NCC Clause C2D14?
It's the National Construction Code provision covering “ancillary elements” like external blinds, requiring them to be non-combustible unless installed at ground level or the level immediately above ground — the rule that makes fire-tested balcony blinds necessary in the first place.
Do I need my body corporate's approval to install a balcony blind?
Almost always, yes — separate from fire compliance, most apartment buildings restrict what can be fixed to a shared facade or balustrade. Check your building's by-laws before ordering.
