In Australia, we don’t just live in our houses; we live in our alfresco spaces. Bi-folding doors are the ultimate way to dissolve the boundary between your kitchen and your deck. However, because they are “top-hung” systems, getting the installation right is critical for long-term performance.
As a top windows and doors supplier in Australia, we manufacture our bi folding patio doors using world-class European CNC precision. Whether you are installing a massive wall of glass or a compact set of bi fold doors for laundry room spaces, here is how to ensure a millimetre-perfect fit.
Jolong Precision vs. Standard Bi-Fold Systems
Why do builders across Sydney, Melbourne, and Perth choose Jolong? It comes down to the engineering behind the frame.
| Feature | Standard “Off-the-shelf” Doors | Jolong Professional Systems |
|---|---|---|
| Joint Accuracy | Manual cutting (prone to gaps). | European CNC Precision (seamless joints). |
| Drainage | Basic sill design. | Integrated Sub-Sill for extreme water-shedding. |
| Hardware | Generic rollers (can sag over time). | Heavy-Duty Doric Rollers (smooth-as-silk glide). |
| Compliance | Minimal performance data. | AS2047 & AS1288 Certified for AU conditions. |
Step-by-Step: Installing Your Bi-Folding Patio Doors
1. The Structural Check (The “No-Brainer” Step) Before ordering your bi fold exterior patio doors, ensure your overhead lintel can support the weight. Our top-hung track carries the entire weight of the glass, so zero-sag is mandatory.
2. Assemble the Frame Jolong frames arrive with CNC-pre-drilled holes. Lay the components on a flat surface. Join the head, sill, and jambs using our provided gaskets. Unlike older systems, our precision joints mean you won’t need excess silicone to stop leaks.
3. Installing the Sub-Sill For bi-folding doors exposed to the elements, the sub-sill is your best friend. It acts as a gutter to direct rain away from your house. Level it perfectly—even a 2mm tilt can affect the “glide.”
4. Hanging the Panels Start with the fixed pivot panel. Attach the hinges and then move to the folding sashes. Because Jolong uses Austrian-designed dies, our panels are dimensionally stable, meaning they won’t warp or stick in the summer heat.
5. Fine-Tuning and Sealing Use the adjustment screws on the bottom rollers to align the gaps. Once satisfied, apply perimeter sealant.
Versatile Applications: From the Patio to the Laundry
While most people think of bi folding patio doors for their backyard, they are also a brilliant space-saving solution for interiors.
- Laundry Rooms: Using bi fold doors for laundry room enclosures allows you to hide your appliances behind a sleek, modern facade without the “swing space” required by standard doors.
- Global Standard: Jolong’s engineering is proven worldwide. From high-performance bi fold doors Vancouver projects (built for sub-zero winters) to our heat-resistant systems for the Adelaide sun, our doors are built to last in any climate.
