Installing a window might look simple on a DIY video, but in Australia’s unpredictable climate—from Brisbane’s tropical storms to Melbourne’s chilly winds—precision is everything. A poorly installed window leads to leaks, rattles, and high energy bills.
As a top windows and doors supplier in Australia, our sliding systems are built with European CNC precision. Whether you are installing a compact 36 x 24 sliding window or a massive 60 x 60 sliding window, follow this professional guide to ensure an airtight, AS2047-compliant finish.
The Jolong Difference: Factory Precision vs. Standard Retail
Before you pick up the drill, understand why Jolong’s engineering makes your installation easier.
| Feature | Standard Retail Windows | Jolong Factory-Direct Systems |
|---|---|---|
| Joint Accuracy | Manual mitre cuts (often gaps). | European CNC 45° Precision (seamless). |
| Waterproofing | Basic drainage holes. | Integrated Sub-Sill Technology (N6 wind rated). |
| Operation | Standard plastic rollers. | Heavy-Duty Doric Rollers (One-finger glide). |
| Frame Thickness | 1.2mm – 1.4mm. | Commercial-grade 2.0mm primary wall. |
Step-by-Step Installation Guide
1. Measure and Check the Opening
Your “rough opening” should be 10mm-20mm larger than the window frame. For a 48×48 sliding window, ensure the studs are plumb and the lintel is level.
- Pro Tip: Never force a window into an opening. If it’s too tight, you’ll bow the aluminium and the sash won’t slide.
2. The Sub-Sill (The Most Important Step)
Many generic guides skip the sub-sill to save time. At Jolong, we consider it mandatory for exterior walls.
- Place the sub-sill on the bottom plate.
- Ensure it is perfectly level.
- The sub-sill acts as a gutter, ensuring that even in a driving storm, water is directed away from your house frame.
3. Flashing and Weatherproofing
Apply high-quality flashing tape to the sill and jambs. This is crucial for preventing “hidden” rot behind your cladding or brick veneer.
4. Fixing the Frame
Lift the frame into place. For a 3 part sliding window (stacker or XOX style), you may need two people due to the frame’s width and weight.
- Use plastic packers at the fixing points.
- Fix through the jambs (the sides).
- Correction: Do not screw through the very bottom of the sill as this can create a leak path. Always use the provided fixing fins or screw through the internal tracks.
5. Installing the Sashes
Once the frame is secure and square, lift the sashes into the track.
- For a 48×60 sliding window or a large 60 x 60 sliding window, adjust the sliding door rollers using the adjustment screw at the bottom of the sash.
- Ensure the sash hits the jamb perfectly even from top to bottom.
