Quick answer
SPC hybrid flooring is the best choice for most Australian apartments - it meets strata acoustic requirements with its built in acoustic underlay, handles concrete slab installation, and is water resistant for multi-level living.
Shop the fix: our apartment flooring collection is 5 Star AAAC acoustic rated with the acoustic underlay already attached. In a real Brisbane apartment test our 9.5mm hybrid scored FIIC 65 against a body corporate requirement of 60, with nothing extra under it.
Why Apartment Flooring Is Different
Choosing flooring for an apartment is not the same as choosing for a house. You are dealing with shared walls, concrete substrates, body corporate rules, and neighbours directly below your feet. Get it wrong and you face noise complaints, strata fines, or forced removal of your new floors.
Here is what makes apartments unique:
- Concrete slab substrate - most apartments sit on reinforced concrete, which transmits impact noise directly to units below
- Strata by-laws - body corporates require certified acoustic testing before approving hard flooring
- Impact noise transfer - footsteps, dropped items, and furniture movement travel through the structure
- Height restrictions - limited floor-to-ceiling clearance means thinner flooring systems are preferred
- Moisture from concrete - slabs release moisture for years after construction, so the floor must be water resistant
Australian Acoustic Requirements Explained
The Building Code of Australia (BCA) sets a minimum standard for impact noise between dwellings: Ln,w + CI must not exceed 62 dB. This is the national baseline, but most strata schemes require performance well above this minimum.
The AAAC Star Rating System
The Association of Australian Acoustical Consultants (AAAC) created a star rating system that most body corporates reference in their by-laws:
| Star Rating | Ln,w + CI (dB) | Performance Level | Typical Requirement |
|---|---|---|---|
| 2 Star | 62 | BCA minimum | Rarely accepted by strata |
| 3 Star | 57 | Basic comfort | Older buildings |
| 4 Star | 52 | Good comfort | Most strata schemes |
| 5 Star | 47 | High comfort | Premium buildings |
| 6 Star | 42 | Excellent | Luxury developments |
Check your by-laws first
Every body corporate is different. Some require 4-star minimum, others demand 5-star. Always request your building's specific acoustic requirements in writing before purchasing flooring.
State-by-State Strata Rules
Queensland: Body corporates can enforce acoustic flooring requirements even without specific by-laws. The Body Corporate and Community Management Act allows committees to require acoustic testing for any hard flooring installation.
New South Wales: Strata by-laws commonly require written approval from the owners corporation before installing hard flooring. NSW has the strictest enforcement, with tribunals regularly ordering flooring removal for non-compliance.
Victoria: Owners corporations can set acoustic requirements through special resolutions. Most Melbourne apartments built after 2004 have acoustic flooring by-laws embedded in the owners corporation rules.
Real Test: 9.5mm Hybrid in a Brisbane South Bank Apartment
Ratings on a spec sheet are one thing. A body corporate wants a field test in a real building. So we had Palmer Acoustics test our 9.5mm hybrid, laid with nothing but its built in underlay, in the living room of a high rise apartment at Brisbane South Bank, with the sound meter in the apartment directly below.
How the test works, in plain English. A tapping machine hammers the floor at a set rate. A calibrated sound meter in the apartment below records how much of that comes through, across every frequency. The result is turned into two scores: L'nT,w, which the National Construction Code uses (lower is better, 62 is the limit), and FIIC, which most Queensland body corporates write into their by-laws (higher is better, 60 is the usual minimum).
Why it matters to you
This building's by-law demands FIIC 60 in kitchens, lounges and bedrooms, and a field test after installation at the owner's cost. Our board passed with a five point margin and no separate acoustic underlay, which is the cheapest possible way to get through a strata approval. Ask us for the acoustic test report when you order and we will send it for your body corporate application.
The floor they tested
Every colour in the 9.5mm hybrid range shares the same core, underlay and acoustic report, so pick the colour you love. Results are specific to that building, so always confirm your own by-law numbers first.
Best Flooring Types for Apartments
Not all flooring performs equally in apartment settings. Here is how the main options compare across the factors that matter most in multi-level living. Thickness matters more than people expect: the total height of board plus underlay decides whether doors still swing and whether the new floor meets the existing tiles.
| Flooring Type | Acoustic Rating | Concrete Slab | Water resistant | Thickness | Strata Friendly |
|---|---|---|---|---|---|
| SPC Hybrid | Excellent (with underlay) | Perfect | 100% | 6.5-9.5mm | Yes |
| Engineered Timber | Good (with underlay) | Good | No | 15mm+ | Yes |
| Luxury Vinyl Plank | Good | Good | Yes | 4-6mm | Sometimes |
| Laminate | Poor | Acceptable | No | 8-12mm | Rarely |
| Solid Hardwood | Poor | Difficult | No | 19mm+ | Rarely |
The other options, honestly
People ask us about all of these every week. Here is the short version of why they usually lose to a 9.5mm hybrid in an apartment.
Laminate and engineered timber
Both need a separate premium acoustic underlay to get near a strata rating. Board plus underlay is often 15 to 20mm, which catches on doors, sits proud of the tiles in the kitchen and bathroom, and needs every door trimmed. Hybrid with its built in underlay stays at 9.5mm.
Carpet
Brilliant for acoustics, and the easiest strata approval of all. But in a living room it is not built for everyday family life or pets, and one spill is a permanent problem. If you would rather not have a hard floor in the bedrooms, carpet there and hybrid everywhere else is a sensible split.
Vinyl plank
At 2 to 5mm, glue down vinyl has almost nothing in it to absorb impact, so it rarely passes an apartment acoustic test on a bare slab. Save it for bathrooms and wet areas, where it is the right floor for a different reason.
Why SPC Hybrid Wins for Apartments
Why SPC hybrid is ideal
- Stone polymer core does not expand or contract on concrete
- Highly water resistant - handles kitchen and laundry life with ease
- Click-lock floating install means no adhesive on the slab
- Thin profile (6.5-9.5mm) preserves ceiling height
- Rigid core pairs perfectly with acoustic underlay
- Achieves 5-star acoustic ratings with the built in underlay
- No acclimatisation period needed
Considerations
- Use a board with the acoustic underlay attached, or a tested board and underlay combination
- Acoustic test report needed for strata submission
- Expansion gaps required at all walls and transitions
- Some body corporates require specific brand certifications

Getting body corporate approval for hard flooring typically takes 2-6 weeks. Here is the process most strata schemes follow:
- Request Your By-LawsContact your body corporate manager and ask for the specific acoustic flooring requirements. Get the required star rating and any approved product lists in writing.
- Choose a Certified Flooring SystemSelect flooring with a tested acoustic underlay combination that meets your building's star rating. The flooring and underlay must be tested together - you cannot mix and match uncertified combinations.
- Submit Your ApplicationProvide the acoustic test certificate, product specifications, proposed installer details, and installation timeline to your body corporate committee.
- Wait for ApprovalThe committee reviews at their next meeting (monthly in most buildings). Some require a special resolution at an EGM for major renovations.
- Install and CertifyUse a qualified installer who follows the manufacturer's specifications exactly. Some buildings require a post-installation acoustic test to confirm compliance.

Acoustic Underlay - The Critical Layer
Your flooring choice only delivers half the acoustic performance. The underlay beneath it does the heavy lifting for noise reduction. Without proper acoustic underlay, even the best SPC hybrid will fail strata requirements.
Acoustic underlay can reduce impact noise by up to 75%. The underlay absorbs vibration before it reaches the concrete slab, preventing sound transmission to the unit below.
- Association of Australian Acoustical Consultants
What to Look For in Acoustic Underlay
- Thickness: 1.5mm-3mm for SPC hybrid (thicker is not always better - too thick can compromise click-lock integrity)
- Material: Rubber or rubber-cork composite delivers the best IIC (Impact Insulation Class) scores
- Certification: Must have a tested acoustic rating when paired with your specific flooring product
- Moisture barrier: Essential for concrete slabs - look for integrated vapour barrier or install separately
- Compatibility: Must be approved by your flooring manufacturer to maintain warranty
Pre-attached vs separate underlay
Our hybrid boards come with the IXPE acoustic underlay already attached and rated 5 Star AAAC on their own, and the Brisbane South Bank field test above passed with nothing else under them. Never lay a second underlay under a board that already has one: two soft layers let the click joints flex and void the warranty. If a board has no underlay attached, use an acoustic underlay that was tested with that exact board.
Installing on Concrete Slabs
Apartment concrete slabs present specific challenges that differ from timber subfloors in houses. Here is what matters:
Moisture Testing
Concrete slabs retain moisture for years. Before installing any flooring, a relative humidity test should read below 75% RH (or as specified by the flooring manufacturer). New buildings under 12 months old almost always require a separate moisture barrier.
Slab Flatness
SPC hybrid flooring requires the concrete to be flat within 3mm over 1 metre. Most apartment slabs meet this standard, but check for:
- High spots where floor levelling compound was applied unevenly
- Dips around plumbing penetrations
- Ridges from formwork joins
- Leftover tile adhesive from previous flooring (must be scraped flat)
Floating vs Glue-Down
For apartments, floating installation (click-lock) is almost always preferred:
- No adhesive bonding to the slab means easier future removal
- Acoustic underlay sits freely between flooring and concrete
- Faster installation with less mess (important in occupied buildings)
- No curing time - walk on immediately after installation
Our Top Picks for Apartments
Based on acoustic performance, concrete slab compatibility, and strata approval success rates, here are our recommended products for apartment installations:
9.5mm SPC Hybrid
The tested board: FIIC 65 in a real Brisbane apartment with nothing but its built in underlay. Thicker core, quieter underfoot, still only 9.5mm high. Plank or herringbone.
6.5mm SPC Hybrid
Same attached underlay, thinner core, lower price. It can work in an apartment, but we recommend a field acoustic test after installation, or ask us for its acoustic report before you commit.
Engineered Timber 15.3mm
Real timber top layer for owner occupiers who want the genuine article. Needs a separate premium acoustic underlay, so check the total height against doors and tiles first.
Colour Picks for Apartments
Apartments benefit from lighter tones that make smaller spaces feel larger and reflect natural light from limited window orientations:
- Pale Sand (6.5mm SPC) - warm neutral that opens up compact living areas
- Snow Grey (9.5mm SPC) - modern cool tone for contemporary apartments
- Light Neutral (Engineered Timber) - natural timber warmth for premium owner-occupied units
- Natural Blackbutt (9.5mm SPC) - classic Australian timber look without the maintenance

None of these are in the by-laws. All of them have caught someone out.
- Book the lift for delivery day. Flooring arrives on a pallet that will not fit in a lift, so the boxes go up by hand. Reserve the goods lift or a move-in slot for the delivery window, and confirm loading dock access with building management the day before.
- Check door clearance and tile heights before you buy. Measure the gap under every door and the height of the kitchen and bathroom tiles. A 9.5mm hybrid usually clears both. Laminate or timber plus a premium underlay usually does not.
- Protect the lift and the common areas. Most buildings charge for scuffed lift walls and hallway carpet. Hang the lift protection blankets and lay a runner in the hallway before the first box moves.
- Ask about work hours and noise rules. Many buildings only allow noisy work between set hours on weekdays. Cutting boards on the balcony at 7am on a Saturday is the fastest way to a complaint.
- Budget for the post installation acoustic test. If your by-law requires it, the test is at the owner's cost and the report is usually due within days of finishing. Book the engineer before the floor goes down, not after.
- Keep the paperwork together. The acoustic report, your written approval, the order number and a photo of the box label. That is your warranty file and your answer to any future committee.
- Order one spare box. A top up order months later may come from a different batch. Keep a box in the storage cage for the day a plank needs replacing.
Frequently Asked Questions
Can I install hard flooring in my apartment without strata approval?
No. In Queensland, NSW, and Victoria, installing hard flooring without body corporate approval can result in orders to remove the flooring at your expense. Some buildings also impose fines. Always get written approval before starting work.
What happens if my flooring fails the acoustic test?
If a post-installation acoustic test fails, you will typically be required to either add additional acoustic treatment (such as a secondary underlay or ceiling treatment in the unit below) or remove and replace the flooring with a compliant system. This is why choosing a pre-certified flooring and underlay combination is critical.
Is SPC hybrid flooring loud to walk on?
SPC hybrid with quality acoustic underlay is quieter than laminate and comparable to engineered timber. The rigid stone polymer core is denser than standard vinyl, which helps dampen in-room sound. The key is the underlay quality - cheap foam underlay produces a hollow sound, while rubber-based acoustic underlay delivers a solid, quiet feel.
Can I use the same flooring in my apartment bathroom?
For kitchens and laundries, yes - SPC hybrid is highly water resistant and handles those rooms with ease. For the bathroom itself we recommend fully adhered glue-down vinyl instead: floating floors have joins water can work into, so they're not the right tool for a wet room. Run hybrid through the rest of the apartment and switch at the bathroom door.
How thick should acoustic underlay be for apartments?
For SPC hybrid, 1.5mm to 3mm rubber or rubber-cork composite is ideal. Thicker is not always better - going beyond 3mm can compromise the click-lock connection and void your flooring warranty. Always use the underlay thickness recommended by your flooring manufacturer.
Do ground-floor apartments need acoustic underlay?
Ground-floor apartments above car parks or commercial spaces still require acoustic compliance. However, if your apartment is on a concrete slab with no dwelling below (such as ground floor on a slab-on-ground), you may not need acoustic underlay for strata compliance. Check your by-laws - some buildings require it universally regardless of level.
How long does the strata approval process take?
Typically 2-6 weeks. Most body corporate committees meet monthly, so timing your application to arrive before the next meeting can save a month. Some buildings have a fast-track process for pre-approved flooring products.
