Explore our export-certified heavy-duty, thermal-break, and hurricane-rated custom OEM aluminium stacker door configurations engineered for global markets.
Purpose-engineered structural integrity, thermal separation, and high-velocity wind load resistance for demanding global climates.
Extensively tested to meet Australian AS2047/AS1288 standards and North American NFRC thermal performance ratings for structural wind pressure, water penetration, and air filtration compliance.
Engineered with heavy-wall 6063-T6 aluminum extrusions and laminated impact glass ($5\text{mm} + 1.52\text{PVB} + 5\text{mm}$) certified for Florida HVHZ design pressure zones up to 80 PSF.
High-density Polyamide (PA66 GF25) thermal barriers integrated within multi-track extrusions drastically reduce thermal conduction, delivering U-factors down to $1.6 \text{ W/m}^2\text{K}$.
As modern architectural design trends prioritize seamless indoor-outdoor transitions, **Aluminium Stacking Doors (Stack Doors)** have evolved from luxury residential features into core structural components for high-end villas, multi-family developments, and commercial hospitality spaces. Unlike traditional two-panel sliding doors or bi-fold doors, multi-track stacker systems utilize parallel tracks that allow multiple panels to glide behind one another, maximizing usable aperture width up to 75% to 80% without encroaching on floor area.
To withstand extreme wind loads (such as Australia’s N5 structural wind rating or Florida’s 80 PSF hurricane standards), custom OEM stack doors utilize primary extrusion frame thicknesses ranging from **1.6 mm to 3.0 mm**. The primary structural alloy specified for high-performance stackers is **6063-T5 or T6 architectural aluminum**, chosen for its optimal tensile strength ($> 205 \text{ MPa}$ for T6) and corrosion resistance when exposed to harsh marine environments.
| Performance Parameter | Standard Commercial Spec | Thermal Break Luxury Spec | Hurricane Impact Spec (Florida 80PSF) |
|---|---|---|---|
| Profile Alloy & Temper | 6063-T5 Aluminum | 6063-T6 High-Tensile | 6063-T6 Reinforced Extrusion |
| Frame Wall Thickness | 1.4 mm – 1.6 mm | 2.0 mm – 2.5 mm | 2.5 mm – 3.0 mm Reinforced |
| Glazing Configuration | 5mm + 12A + 5mm Tempered | 6mm Low-E + 16A + 6mm Argon | 5mm Temp + 1.52 PVB + 5mm Temp / 12A / 6mm |
| Thermal Transmittance (U-Value) | $2.8 – 3.2 \text{ W/m}^2\text{K}$ | $1.4 – 1.8 \text{ W/m}^2\text{K}$ | $1.6 – 2.0 \text{ W/m}^2\text{K}$ |
| Design Pressure (DP) Rating | 35 – 45 PSF | 50 – 60 PSF | 80 PSF (HVHZ Compliant) |
| Acoustic Isolation (STC) | STC 32 dB | STC 38 – 42 dB | STC 40 – 44 dB |
A primary challenge with multi-track aluminium doors is thermal bridging across expansive openings. Aluminium exhibits a thermal conductivity rate of approximately $200 \text{ W/m}\cdot\text{K}$. To prevent thermal loss and interior condensation in extreme hot or cold zones, our OEM designs integrate a **24mm to 34mm Polyamide (PA66 GF25)** thermal barrier strip.
When combined with double- or triple-glazed Insulated Glass Units (IGUs) incorporating **Warm Edge Polymer Spacers** and **Argon Gas Fillings**, the thermal bridging path is broken. This setup achieves superior thermal insulation performance, aligning with global zero-carbon building initiatives and NFRC Energy Star criteria.
Smooth operation across 3-track, 4-track, or 6-track configurations depends heavily on roller carriage engineering and track geometry:
Key technical shifts real estate developers, contractors, and wholesale importers must consider for upcoming procurement cycles.
Future multi-track stackers are increasingly adopting motorized magnetic-drive actuators integrated with home automation platforms (Zigbee/KNX), enabling touchless control and automated weather sensors.
Architectural demand is moving toward ultra-slim vertical interlock profiles (**20mm to 25mm sightlines**) without compromising structural moment of inertia, using hidden internal steel reinforcement pins.
Global developers require verified EPD (Environmental Product Declaration) certificates. Sourcing is shifting toward primary aluminum smelted using renewable hydro-power to meet strict carbon tax tariffs.
Founded in 2004 in Foshan, China's premier aluminum fabrication capital, Doorreme operates a 123,000 m² modern manufacturing facility staffed by over 800 skilled workers and fenestration engineers.
Direct technical answers addressing engineering specifications, OEM customization options, lead times, and global shipping.
Our stack doors are custom-fabricated to meet regional compliance metrics, including Australian Standards AS2047/AS1288 (NATA accredited lab tested), North American NFRC ratings, CSA compliance, and Florida Building Code (HVHZ) 80 PSF impact resistance.
For standard profile dies in default anodized black/powder coat finishes, the MOQ is 1 unit for project quotes. For customized profile extrusion dies, our typical MOQ starts at 3 metric tons of aluminum extrusions, with die creation fees fully refundable upon container volume targets.
Yes. We offer sealed insulated cavity glass units (e.g., 5mm + 27A + 5mm) with integrated motorized or manual magnetic louvers, keeping dust away while maintaining privacy and low maintenance.
We partner directly with leading international hardware manufacturers including German Roto, Siegenia, and Hoppe, as well as premium Chinese brands (CMECH, Kin Long) backed by a 10-year factory operational warranty.
Our stacker sills incorporate a stepped sub-sill pan system with continuous EPDM dual gaskets, hidden drainage slots, and anti-backflow flap valves designed to prevent water ingress during severe storm conditions.
For coastal and high-salinity marine environments, we recommend PVDF (Fluorocarbon) coating or Qualicoat Class 2 Powder Coating with an anodized pre-treatment layer ($> 25 \mu\text{m}$ thickness), rated to withstand 3,000+ hours of continuous salt spray testing.
Yes. Our in-house engineering team provides complete 2D CAD elevation drawings, cross-sectional details, structural wind load calculation sheets, and 3D Revit BIM models prior to starting production.
Doors are packaged with protective film, edge protectors, heavy-duty bubble wrap, and packed inside fully enclosed fumigation-free plywood crates (Cratelok design) to eliminate transit damage.
