2) Technical differences that matter (frame material, track, rollers, weight class)

Not all cavity units are built the same. The biggest real-world differences show up in long-term smoothness, stability/alignment,
and the ability to handle heavier doors.

Premium construction (Premium 65 / 125 / 150)

Verified on our product pages:

  • Full aluminium cavity frame
    (Premium 65 / 65 Double include full aluminium cavity frame).
  • Aluminium powder-coated top track designed to be roller jump-proof
    (Premium 65 / 65 Double).
  • Metal body rollers with 4 bearings, 4 nylon wheels and a secure thread-lock
    (Premium 65 / 65 Double).

    and closing jamb.

Typical retail “industry average” construction (example: Hume Evolution cavity unit)

Many common retail cavity units are supplied as pine (timber) cavity units and commonly list:

  • Available in pine (timber unit)
  • Jump free U track (smooth operation)
  • Smooth 4 wheel ball-bearing carriages
  • Maximum door mass 70kg (example listing)

Example sources:
Bunnings – Hume Evolution (pine / U-track / 4-wheel / 70kg)

Why aluminium frames + aluminium tracks can be an upgrade vs timber cavity units

  • More consistent alignment over time:
    aluminium frames don’t rely on timber structure in the same way, which helps keep the cavity system running true when a wall settles or moves.
  • More consistent running surface:
    an aluminium powder-coated track provides a uniform surface for rollers, helping reduce wear and maintain smooth operation.
  • Higher-grade roller package:
    metal-body rollers with multiple bearings distribute load more evenly and typically feel smoother and “more solid” under frequent use.
  • Better suited to higher door weights:
    Premium systems step up to 125kg and 150kg classes when you move into larger/heavier doors (architectural timber, aluminium, glass).
  • Less rattle / more control:
    guides, brushes, stoppers and closing jamb details help keep the door stable and reduce vibration and noise.

Conclusion

Premium 65/125/150 differs from many common timber cavity units by focusing on a more engineered build:
full aluminium cavity frame, aluminium powder-coated jump-proof top track,
and a premium roller package (metal body rollers, multiple bearings, nylon wheels).
This is designed to deliver smoother running and more consistent performance over time.

For standard internal doors, Premium 65 is priced competitively against typical retail options while offering an upgraded construction package.
For heavier doors and architectural applications, Premium 125 and Premium 150 provide higher rated systems matched to those loads.
