How Aluminium Bifold Doors Work
Bifold doors fold and stack neatly to the side, unlike sliding doors which only open partially.
They use precision-engineered components:
- Precision hinges – Allow smooth folding action
- Top and bottom rollers – Distribute weight evenly
- Multi-point locking – Security across entire system
- Flush threshold systems – No step between inside and out
This creates truly seamless indoor-outdoor living.
Bifold doors completely disappear, transforming your home and creating spectacular entertainment spaces.

Learn more: Curtain Wall Industry Standards
Structural Glazing: Frameless Luxury
Structural glazing takes curtain walls to the next level – the glass appears frameless.
Glass panels are bonded directly to the structure using silicone, with no visible frames.
This creates:
- Ultra-luxury appearance – Pure glass facades
- Uninterrupted views – Nothing blocks sightlines
- Modern masterpiece – Iconic architectural statement
Used in high-end homes in:
- Franschhoek – Wine estate luxury homes

Frequently Asked Questions
How much do aluminium bifold doors cost in South Africa?
Most aluminium bifold doors cost between R18,000 and R120,000 depending on size, glass specification, and quality. A standard 3-meter, 4-panel bifold typically ranges from R30,000 to R55,000 installed. Larger 6-meter systems can reach R80,000-R120,000. Double glazing adds 30-50%, thermal break systems add 20-40%. Get personalised quotes from certified installers near you for accurate pricing.
Are curtain walls suitable for houses?
Yes, curtain walls are increasingly used in luxury residential architecture. They create stunning modern homes with floor-to-ceiling glass, maximising views and natural light. However, they require professional engineering and are typically only cost-effective for high-end projects. Popular in areas like Cape Town and Sandton where views and architectural impact justify the investment.
Are bifold doors better than sliding doors?
Bifold doors allow 90-95% opening, creating true indoor-outdoor flow, while sliding doors only open 50%. Bifolds offer superior lifestyle transformation and luxury appearance but cost significantly more. Sliding doors are more budget-friendly and simpler to install. Choose bifolds if you want to completely open your home to the outdoors; choose sliding if budget is the primary concern. See our sliding doors guide for comparison.
How long does aluminium joinery last?
High-quality aluminium joinery lasts 30–50 years with minimal maintenance. The powder coating may need refreshing after 20-25 years, but the aluminium structure itself remains sound. Hardware like hinges and rollers may need replacement after 15-20 years of heavy use – these are serviceable parts. Regular cleaning and annual lubrication ensure maximum lifespan. Read our maintenance guide for longevity tips.
Is custom aluminium joinery worth it?
Yes – for homeowners who value design, quality, and long-term value. Custom joinery transforms living spaces, adds significant property value (often exceeding the investment), and provides 50 years of durability. The Bryanston case study showed a R85,000 investment adding R300,000+ in property value. For commercial properties, the professional image and energy efficiency provide excellent ROI.
What is the difference between curtain wall and structural glazing?
Curtain walls use visible aluminium frames to support glass panels. Structural glazing bonds glass directly to the structure with silicone, creating a frameless appearance. Structural glazing is more expensive (R8,000-15,000/m² vs R3,500-9,000/m²) but offers cleaner aesthetics. Both require professional engineering, but structural glazing demands even greater expertise. Common in luxury projects like Franschhoek wine estates.
Do bifold doors need planning permission?
For like-for-like replacement of existing openings, planning permission is generally not required. For new openings, enlarging existing openings, or structural changes, municipal approval may be needed. Heritage properties or conservation areas may have additional restrictions. Always check with your local municipality and ensure your contractor handles any required approvals.
Can I install bifold doors myself?
No – absolutely not. Bifold doors require precision installation to ensure smooth operation, weather sealing, and structural safety. Incorrect installation leads to jamming, water leaks, and potential collapse. Always use certified professionals with bifold-specific experience. Verify credentials through insurance and accreditation checks.
Final Thoughts
Custom aluminium joinery represents the future of architecture in South Africa.
It provides:
- ✅ Luxury – Stunning design that impresses
