How to Choose a Cavity Slider in NSW (2025 Expert Guide)
Choosing the right cavity slider for your home in New South Wales is essential for ensuring smooth operation, a modern look, and long-lasting performance. Whether you’re renovating, building new, or upgrading an existing doorway, this guide will help you understand what matters when selecting a cavity sliding system.
1. Consider the Thickness of Your Wall (Stud Size)
The first step is to check if your wall uses 76mm or 90mm studs.
-
76mm stud walls — suitable for lightweight doors and standard systems
-
90mm stud walls — suitable for stronger, premium, or heavy doors
If you are unsure — our team can measure it for you.
2. Choose the Right Door Type
Common door materials:
-
Timber doors — warm, classic finish
-
MDF / painted doors — budget friendly
-
Glass doors — modern, bright, ideal for smaller rooms
-
Solid-core doors — great for noise reduction
- Aluminium glased doors — modern
For heavy or oversized doors, choose a reinforced cavity system Premium150 System.
3. Soft-Close Mechanism (Highly Recommended)
Modern homes in NSW almost always use soft-close because:
-
It prevents slamming
-
Increases lifespan of rollers
-
Feels premium and smooth
-
Safer for kids
Premium Sliding Doors systems can be upgraded to soft-close.
4. Select the Right Cavity Frame Quality
Not all cavities are equal. A good system must have:
-
Strong aluminium frame
-
High-quality rollers
-
Reinforced tracking
-
Smooth, quiet operation
-
Warranty (we provide long-term guarantees)
Cheap frames often bend, jam, and wear quickly.
5. Measure Your Opening Correctly
Key things to measure:
-
Door width
-
Door height
-
Available wall space
-
Clearance for pocket insert
-
Ceiling height
-
Flooring thickness
Incorrect measurements are the #1 cause of installation problems.
