Bi Fold Window

Bi-fold windows are a stylish, space-transforming choice for modern homes worldwide. Multiple folding panels open fully to flood interiors with natural light and fresh air, stacking neatly aside to create seamless, expansive connections between indoor living spaces and outdoor areas.

 

A dedicated hinged access panel provides convenient everyday entry without unfolding the entire system—ideal for quick access, family gatherings, entertaining, or enjoying views.

 

This smart blend of dramatic wide openings, practical daily functionality, enhanced comfort, superior security, and excellent energy efficiency makes bi-fold windows perfect for any climate or lifestyle.

Custom Aluminium Bi-Fold Windows for Project Supply

Fenghui manufactures custom aluminium bi-fold windows for builders, developers, window distributors, architects and commercial fit-out contractors.

Instead of limiting buyers to several retail sizes, each FH70 window can be coordinated with the project window schedule, architectural opening and nominated glazing requirements. Overall dimensions, panel layout, stacking direction, frame finish, glass, hardware and accessories are confirmed before production.

The non-thermal-break FH70 system is a practical option for covered kitchen serveries, restaurant counters, hospitality spaces, retail openings and budget-controlled building projects where a thermally broken frame is not specified. For exposed external openings, the final configuration should be selected according to the project’s wind, water, glass and energy-performance requirements.

 

Configure Each Aluminium Bi-Fold Window Around the Opening

The performance and usability of aluminium bi-fold windows depend on more than overall width and height. Fenghui reviews the complete opening arrangement before confirming production.

Specification Item Available Project Direction Why It Matters
Panel configuration Multiple folding panels configured to suit the opening Balances panel weight, clear opening and visual proportions
Stacking direction Stack to the left, right or nominated side, subject to system limits Keeps folded panels away from counters, furniture and service paths
Opening direction Inward- or outward-folding configuration Coordinates the window with internal and external usable space
Glass configuration Double glazing, Low-E, laminated, tempered, tinted or frosted glass Addresses safety, privacy, solar control, acoustic and comfort requirements
Frame finish Standard or custom powder-coated finishes Matches façade schedules, joinery and other aluminium windows and doors
Locking and hardware Multi-point locking with project-selected handles and folding hardware Supports security and repeated operation
Sealing and drainage Seal and sill details selected for the installation position Important for external openings exposed to wind and rain
Insect screening Project-specific screen options where compatible Suitable for kitchens, residential entertaining areas and hospitality openings

Aluminium Bi-Fold Window or Bi-Fold Door?

A folding window and a folding door serve different architectural purposes and should have separate specifications.

Product Typical Installation Primary Function
Aluminium bi-fold window Above a counter, sill or kitchen benchtop Creates a serving opening, ventilation area or visual connection
Aluminium bi-fold door Full-height opening with a walk-through threshold Provides pedestrian access between indoor and outdoor spaces

If pedestrian access is required, view our custom aluminium bi-fold doors instead.

Frequently Asked Questions

Can aluminium bi-fold windows be made to custom sizes?

Yes. Fenghui manufactures aluminium bi-fold windows according to project opening dimensions. Final overall size, panel width and panel quantity are confirmed after reviewing the opening, glass weight and hardware limits.

How do I choose the number of folding panels?

The recommended panel layout depends on overall opening width, available stacking space, preferred folding direction and required clear opening. Fenghui can propose a configuration after receiving the architectural dimensions.

Are FH70 bi-fold windows suitable for exposed external openings?

Suitability depends on the window size, installation position, wind pressure, water-performance requirement and glass specification. These requirements should be provided before quotation so the available system performance can be checked.

Can the frame colour match other windows and doors in the project?

Standard and custom powder-coated finishes can be coordinated across the project. Colour references should be confirmed before production to maintain consistency between different batches and product types.

What technical documents are available for project approval?

Depending on the selected configuration and project requirements, Fenghui can confirm the availability of product specifications, shop drawings, glass information, finish details and applicable performance documentation during the quotation stage.

What is the production lead time?

Lead time depends on quantity, dimensions, glass, finish and hardware configuration. The confirmed production schedule will be provided after drawings and specifications are approved.

Maintenance Tips

Twice-yearly care keeps bi-fold windows gliding smoothly, sealing tightly, opening fully, and lasting for years. Contact a specialist for adjustments or persistent issues.

01
Clean frames & glass

Use mild detergent/water or glass cleaner + soft cloth. Fold panels fully open for safe access to both sides. 1–2 times yearly (more if dusty/coastal).

02
Clear tracks & pivots

Brush or vacuum dirt, dust, leaves from top/bottom tracks, hinges, and pivot points. Keep channels free to prevent binding.

03
Lubricate hardware

Apply silicone-based lubricant to rollers, pivots, hinges, tracks, and multi-point locking mechanisms every 6–12 months (or when movement feels stiff). Wipe excess.

04
Inspect seals & weatherstripping

Check gaskets and brushes for cracks, flattening, or gaps. Clean gently; replace damaged ones to stop drafts, leaks, and noise.

05
Test alignment & operation

Fold/unfold fully; ensure smooth, even movement and secure locking at every point. If panels drag, bind, or misalign, do not force—call a professional for adjustment.

06
Clean insect screens (if fitted)

Remove detachable screens; rinse with water, brush gently, dry, and reinstall.

07
Check drainage

Clear any drainage holes/slots in bottom track/sill to prevent water pooling.
