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 window systems are commonly specified across:
System selection should account for:
High Performance Bi-fold Window
| Maximum Frame Height* | 1600mm |
| Maximum Panel Width* | 900mm |
| Maximum Glass Thickness | ≤20mm |
| SHGC Range | 0.25-0.57 |
| Uw Range | 3.6-6.1 |
*Maximum Frame Height and Panel Widths indicated are interdependent and subject to individual site conditions.
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:
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.
Bi-fold window systems integrate across facade, sector and specification decisions:
Bi-fold windows operate on the same folding panel principle as bi-fold doors but are sized and configured for window openings — typically counter height or above floor level — rather than full floor-to-ceiling door openings. Bi-fold windows are commonly used for servery counters, bar openings and alfresco connections where a lower sill height is appropriate.
Panel count depends on the opening width and the specific series. Bi-fold systems can typically accommodate configurations from two panels upward, stacking to one side or both. Our team can advise on suitable configurations for a given opening width and structural conditions.
Series selection is important in exposed locations. Weather resistance performance varies across the range and threshold design is a critical consideration in coastal or wind-exposed environments. Our team can advise on appropriate series and detailing for specific exposure conditions.
Low-profile and flush threshold options are available on selected series, improving accessibility and reducing trip hazard risk. Threshold selection should be confirmed early as it affects both the structural connection and the finished floor level relationship.
Yes. Our team can review opening dimensions, structural conditions and usage requirements to recommend suitable panel configurations, stacking arrangements and series options. Upload drawings or contact us to discuss your project.
