About the GS1, GS2 & GS3 Glass Stacking Doors
The Glass Stacking Door range by The Australian Trellis Door Co is one of the most innovative commercial glass folding door systems available in Australia. Constructed from extruded aluminium with 6.38mm laminated safety glass panels as standard, the GS range combines a modern, architectural aesthetic with practical security and space efficiency.
All three variants are top-hung with no floor track — the door panels are suspended from commercial-grade stainless steel rollers in carriages that glide in an overhead aluminium track, eliminating floor-level trip hazards entirely. The system operates manually and stacks compactly to one or both sides of the opening depending on side room clearances.
The GS range is suitable for both internal and external commercial, retail and hospitality applications and is used in airports, shopping centres, restaurants, hotels, hospitals, aged care facilities, schools and universities, medical centres, offices and retail stores across Australia. Each door is custom-manufactured to the specific opening by ATDC tradespeople.

Glass vs Polycarbonate Infill
| Feature | Glass (Standard) | Polycarbonate (Optional) |
|---|---|---|
| Thickness | 6.38mm laminated safety glass | 6mm |
| Options | Clear or translucent | Clear or opaque |
| Weight | Heavier | Lighter — better for larger panels |
| Safety | Laminated — holds together if broken | Impact resistant |
| Aesthetic | Premium architectural look | More functional, cost-effective |
| Best for | Premium retail, restaurants, hospitality | Airport kiosks, high-traffic, weight-sensitive |
Who the Glass Stacking Door Is For — and Who It May Not Suit
| This product suits… | This may NOT be right if… |
|---|---|
| Retail shopfronts in shopping centres requiring a premium glass aesthetic | You need a motorised door (GS range is manual only) |
| Restaurants and cafes using glass doors as part of the design | Your floor has more than 25mm deviation left-to-right or 25mm ext-to-int beyond the specified tolerance |
| Airport kiosks and terminal retail | Your overhead structure cannot bear a structural support beam with no deflection |
| Any opening up to 6,000mm wide (GS1/GS2) or unlimited (GS3) | You need a fully sealed weather barrier — the GS does not provide a fully weatherproof solution for external applications |
| Hospitals, aged care facilities, and hotels seeking a modern glass facade | You need BCA egress on an opening that does not meet minimum size requirements |
| Architects and fitout designers requiring a minimal-track modern aesthetic | Budget is the primary driver and a glass aesthetic is not required |
Real-World Use Case Scenarios
Scenario 1 — lululemon Shopping Centre Shopfront: lululemon installed ATDC Glass Stacking Doors (GS range) on their retail shopfront at Pitt Street Mall, Sydney, project managed by Johns Lyng Shopfit Services, Doncaster, VIC. The top-hung system opens completely, leaving an unobstructed entrance and a clean architectural appearance during trading hours. The laminated safety glass infill provides full product visibility and security after hours. Read more
Scenario 2 — Bengong, Chatswood Metro Interchange: ATDC installed a centrally hung GS3 glass stackable door system to secure the Bengong tenancy at Chatswood Metro Interchange, Sydney. Project managed by Vision Craft Construction, Sefton, NSW. The minimalist aesthetic and no-floor-track design was specified for a premium food and beverage retail environment. Read more
Scenario 3 — Airport Kiosk: A free-standing kiosk operator at a major Australian airport needs a glass door system that completely opens the kiosk frontage during trading hours and closes securely overnight. The GS inward opening panels with polycarbonate infill provide a lightweight, fast-stacking solution that maximises the kiosk opening width within the space constraints.
Scenario 4 — Restaurant or Café with Street Frontage: A restaurant owner wants floor-to-ceiling glass doors that open the entire frontage in summer. The GS2 bi-parting configuration stacks to both sides, creating a completely open frontage. At night, the system closes, the up/down shootbolt locks secure the panels, and the laminated safety glass provides both visibility and a deterrent.

Before You Buy — Checklist
- Determine which GS type suits your opening: GS1 (internal opening), GS2 (outward opening), or GS3 (centrally hung, unlimited width).
- Measure your opening width and height accurately. GS1 and GS2 max 3,000mm high x 6,000mm wide. GS3 max 3,000mm high, unlimited width.
- Check your floor level. Left-to-right deviation must not exceed 25mm. External-to-internal deviation must not exceed 25mm from track centreline to 1,000mm either side.
- Confirm your overhead structural support capability. The builder must provide an overhead structural support beam, engineer certified, with no deflection or sag.
- Confirm square and level vertical members are achievable to within 10mm tolerance.
- Check your side room clearances for stacking.
- Choose infill: standard 6.38mm laminated safety glass (clear or translucent) or 6mm polycarbonate (clear or opaque).
- Choose finish: natural anodised (standard) or powder coat to Dulux Duralloy colour.
- Consider whether BCA egress is required for your application.
Common Mistakes When Buying a Glass Stacking Door
- Not providing a structural overhead support beam — the GS system requires a structural engineer-certified beam with zero deflection. A standard timber lintel may not be adequate. Confirm with your builder before ordering.
- Underestimating the floor level tolerance requirements — more than 25mm left-to-right deviation, or more than 25mm external-to-internal beyond 1,000mm from track centreline, will prevent correct installation.
- Ordering manual operation when motorised is needed — the GS range is manual only. If motorised operation is required, consider another product.
- Choosing glass infill when the opening is very wide and panel weight is a concern — individual panels are limited to 40kg and 750mm wide. For very wide openings, polycarbonate may be preferred to reduce panel weight.
- Not specifying the BCA egress option at time of manufacture — this must be incorporated during manufacturing and cannot be easily retrofitted.
- Assuming GS1, GS2, and GS3 are interchangeable — they have different opening directions and the GS3 is fundamentally different (centrally hung) with unlimited width capability. Consult ATDC before specifying.
Technical Limitations
- Manual operation only — the GS range is not available with motorised or electric operation.
- Requires a structural overhead support beam with no deflection — approved by an engineer.
- Opening must be square and level to within 10mm tolerance.
- Floor level deviation limits: left-to-right maximum 25mm; external-to-internal maximum 25mm from track centreline to 1,000mm either side.
- Maximum individual panel weight 40kg; maximum panel width 750mm.
- GS1 and GS2 maximum width 6,000mm — GS3 has unlimited width.
- The GS range does not provide a fully weatherproof solution for external applications.
Problem → Product → Outcome
| Problem | GS Solution | Outcome |
|---|---|---|
| Shopfront needs security without sacrificing the architectural glass aesthetic | GS laminated safety glass infill — full visibility and security | Premium retail appearance maintained day and night |
| Bottom track creates a trip hazard at the entrance | GS is fully top-hung — no floor track | Unimpeded, accessible entrance |
| Very large opening requires unlimited width | GS3 centrally hung — unlimited width | Any shopfront width accommodated without mullions |
| Restaurant wants fully open frontage in summer | GS2 bi-parting outward opening — stacks fully to both sides | Completely open frontage; panels disappear to each side |
| BCA emergency egress required for public venue | BCA-compliant egress lock option — single down-action handle | Code-compliant emergency exit from any panel |
| Architect requires minimal hardware for a clean aesthetic | Top-hung system with stainless steel carriages concealed in overhead track | No visible floor hardware; panels glide in clean overhead aluminium extrusion |
Compatibility
| Works With | Does Not Work With (or confirm with ATDC) |

Who Should NOT Buy the GS Range
The Glass Stacking Door range is the right product when a premium glass aesthetic, top-hung no-track design, and architectural finish are priorities.

Common Questions About the GS1, GS2 & GS3 Glass Stacking Doors
How much does a glass stacking door cost?
Glass Stacking Doors vary in cost depending on GS type, height, width, infill, finish, and location. Request a free no-obligation quote from ATDC at trellisdoors.com.au/contact or call 1800 657 435.
What is the difference between GS1, GS2, and GS3?
All three variants are top-hung with no floor track, but they differ in opening direction. GS1 panels open internally. GS2 panels open outward. GS3 panels are centrally hung — a different system that allows unlimited width with a maximum height of 3,000mm, compared to the 6,000mm maximum width of GS1 and GS2.
Does the glass stacking door require a bottom track?
No. All three GS variants are fully top-hung with no bottom track required. The panels are suspended from commercial-grade stainless steel rollers in carriages that glide in an overhead aluminium track, leaving the floor completely clear. This eliminates trip hazards and creates a clean, unobstructed entrance.
What glass is used in the GS stacking doors?
The standard infill is 6.38mm thick clear or translucent laminated safety glass. Laminated glass is the safety standard for commercial glazing — it holds together when broken rather than shattering into shards. An optional polycarbonate infill (6mm, clear or opaque) is available for a lighter weight solution.
Is the GS glass stacking door available with motorised operation?
No. The GS1, GS2, and GS3 glass stacking doors are manually operated only. If you require motorised or automated operation, contact ATDC to discuss alternative products in their commercial security range.
What structural support is required for a glass stacking door?
The builder must provide a structural overhead support beam capable of supporting the full weight of the door with no deflection or sag. Engineering certification is essential. Standard timber lintels may not be adequate. The opening must also have square and level vertical members to within 10mm tolerance.
Can I use a glass stacking door on an external shopfront?
The GS range does not provide a fully weatherproof solution for external applications. Contact ATDC on 1800 657 435 to discuss your specific requirements and whether an alternative product may be more suitable.
Where can I get a glass stacking door installed in [city]?
The Australian Trellis Door Co installs Glass Stacking Doors across all Australian states and territories including Sydney, Melbourne, Brisbane, Adelaide, Perth, Canberra, Darwin, Hobart, Newcastle, Gold Coast, Sunshine Coast, Townsville, Cairns, and all regional areas.
