Cork Flooring for Strata & Apartments in Australia

What strata acoustic rules actually require

Under the National Construction Code, floors separating sole-occupancy units in Class 2 buildings must achieve an impact sound transmission rating of L'nT,w + Ci ≤ 62 (deemed-to-satisfy). Most owners' corporations layer additional by-laws on top - typically requiring an acoustic report from a qualified consultant before any hard-floor change is approved.

Comcork's structural impact reduction (around 19 dB depending on profile) means it generally clears these thresholds on a standard concrete slab without a separate acoustic underlay. That's the difference between a single-trade install and a layered build-up that eats floor height and budget.

Why cork-rubber suits apartment living

• Quiet underfoot for the unit below - the original reason cork was specified in apartments decades ago.
• Warm and forgiving for the resident on top - better than tile or engineered timber for kids, pets, and bare feet.
• Slip-resistant in wet areas without the cold-tile feel - relevant for ageing-in-place and accessibility upgrades.
• Low-VOC and low-allergen - useful in smaller, less-ventilated apartment footprints.
• Sealed sheet with cold-welded chemical seams in wet areas - limits water ingress to the unit below.

Owners' corporation approval, in practice

Most strata schemes will ask for: the product technical data sheet, an impact-isolation test report or acoustic consultant statement, the proposed installation method (including underlay if any), and the installer's insurances. Premrest can supply the product documentation and installation method statement. The acoustic report is project-specific and usually obtained separately, against the actual slab and ceiling build-up of the building.

Where carpet tile still wins in apartment buildings

Hard floor isn't always the answer. Carpet tile is often the better call in shared corridors, lift lobbies, and ground-floor amenity rooms where acoustic absorption matters as much as impact isolation, and where individual tile replacement keeps long-term maintenance simple. Premrest's carpet-tile capability sits at modularcarpet.com.au if that's part of the same project.

Common-property vs unit installs

Premrest scopes both: common-property works (lobbies, corridors, amenity floors) typically via the building manager or strata committee, and within-unit works directly with the lot owner once owners' corporation approval is in place. Staged installs around occupied buildings - including after-hours and weekend works - are part of the standard scope.
