Bi‑Fold Window Systems

Full-Width Opening & Indoor-Outdoor Connection

Aluminium bi-fold window systems delivering full-width opening capability and indoor-outdoor connection for architectural, hospitality and commercial applications.

Bi-fold window systems are specified where maximum opening width and indoor-outdoor connection are the primary design intent. Panels fold and stack to one or both sides, creating an unobstructed opening across the full width of the frame. This makes bi-fold systems a common choice for kitchen servery windows, hospitality counters, open-plan living connections and commercial applications where flexible opening and closing of large glazed areas is required. Hunter Windows supplies and installs bi-fold window systems from the AWS Elevate range, available in configurations to suit opening width, panel count and performance requirements.

Bi-Fold windows

Typical Applications

Bi-fold window systems are commonly specified across:

  • Kitchen servery and bar counter openings
  • Hospitality venues and cafes with indoor-outdoor service areas
  • Architect-designed homes with open-plan living connections
  • Commercial and retail spaces requiring flexible open frontages
  • Alfresco and entertainment areas
  • Multi-residential common areas and amenity spaces

Key Performance Considerations

System selection should account for:

  • Opening width and panel count — bi-fold systems accommodate multiple panels across large openings; panel count and stacking configuration (one side or both) should be determined early in the design process
  • Panel size and weight — individual panel dimensions affect hardware loading and ease of operation; maximum panel sizes vary by series
  • Weather resistance — bi-fold systems in exposed locations require careful consideration of threshold design and weather sealing; series selection should reflect exposure conditions
  • Thermal performance — U-value and SHGC ratings vary across series; glazing selection significantly influences thermal outcomes across large glazed areas
  • Hardware and operation — folding hardware quality directly affects long-term ease of operation and durability; top-hung systems reduce floor track obstruction and improve accessibility
  • Threshold design — low-profile or flush threshold options improve accessibility and reduce trip hazard risk, particularly in hospitality and public-facing applications
  • Security — locking configuration across multiple panels requires careful consideration; series selection should reflect project security requirements

Energy Performance & Thermal Ratings

Bi-fold window systems are WERS rated, providing verified U-value and Solar Heat Gain Coefficient (SHGC) data for use in NCC energy compliance calculations and thermal modelling.

Key energy performance factors for specification:

  • U-value — measures the rate of heat transfer through the window assembly; lower values indicate better thermal insulation across large glazed opening widths
  • SHGC — measures solar heat gain through the glazing; particularly relevant for large bi-fold openings on north and west-facing facades where solar exposure is significant
  • Glazing selection — performance outcomes vary significantly with glass type; double glazing, low-e coatings and laminated options are available across the range
  • ThermalHEART series — thermally broken aluminium frames reduce heat transfer at the frame, improving overall window U-values for projects with elevated energy performance requirements

SHGC and U-value ranges for each series are shown in the Available Range section above. For detailed energy performance data and climate zone guidance, see our WERS & Energy Performance and Thermally Broken Frames resource pages.

Integration

Bi-fold window systems integrate across facade, sector and specification decisions:

  • Facade Solutions — commonly used within commercial framing and shop front assemblies; suited to applications requiring flexible open frontages or full-width indoor-outdoor connections
  • Sectors — most commonly specified in architectural homes and retail and hospitality environments; also applicable in aged care and education common areas where indoor-outdoor connection supports amenity
  • Specification — glass selection, colour finishes and hardware are all configurable; threshold and track options vary by series and should be confirmed early; refer to the Specification section for detail on available options
