Can Cavity Sliders Be Installed in Existing Walls? The Complete 2025 Renovation Guide (Using Premium Sliding Doors Systems)

🧭 Summary

Yes — cavity sliders can be installed in existing walls. However, this is only possible when the wall is non-load-bearing, the studs can be reframed, and there is no plumbing inside the cavity. Additionally, Premium Sliding Doors systems are designed to integrate smoothly into both modern and older homes. Therefore, they offer one of the most renovation-friendly solutions in Australia.

1. When Installing a Cavity Slider in an Existing Wall Is Possible

In most cases, installation is achievable once plasterboard is removed. Consequently, the framing becomes accessible and allows builders to prepare the wall structure for a cavity pocket. Furthermore, the process is usually straightforward when key structural conditions are met.

✔ The wall is non-load-bearing

This is the most important requirement. If the wall does not support structural loads, it can be safely opened. As a result, the studs may be removed and replaced by Premium65, Premium125, or Premium150 aluminium cavity pockets.

✔ The existing studs can be removed or reframed

Premium pockets provide a straight and stable internal cavity. Therefore, they work exceptionally well in older homes where timber frames may no longer be aligned. Additionally, Premium pockets:

• do not warp
• maintain perfect alignment
• replace old timber studs
• remain structurally stable for decades

✔ Electrical wiring can be relocated

The cavity pocket must remain empty. However, most electricians can relocate switches or power points during plasterboard removal. Consequently, wiring rarely prevents installation.

✔ Door size fits within wall structure

Premium systems support standard and custom door heights. Therefore, both low ceilings and oversized openings can be accommodated. For example:

• Low ceilings → Premium65 / Premium125
• Oversized doors → Premium150

2. When Installation Is Not Possible Without Major Work

Although cavity sliders suit most homes, several situations require additional structural changes. As a result, installation may become more complex and costly.

✘ The wall is load-bearing

Load-bearing walls support the floors or roof above. Therefore, removing studs requires a structural beam or lintel. Additionally, engineering approval and extra labour are needed.

✘ Plumbing runs inside the wall

Plumbing cannot remain in the cavity space. Consequently, the wall must be reframed or the door installed elsewhere.

✘ The opening is too narrow

Older homes often have tight framing. However, builders can widen the opening if required. This is a common part of renovation work.
