If you’re looking for a way to prevent unwanted noise from entering your home, roller shutters could be your solution. Learn more about the broader benefits and types of residential roller shutters for Perth homes to make the best choice for your property. This makes them an excellent choice for shift workers, children’s rooms, and anyone sensitive to sound — especially when considering bedroom roller shutters to maximise restful sleep.
How noise-reducing roller shutters work
Roller shutters reduce airborne sound through three core mechanisms: mass (dense slats that block sound), damping (foam cores or seals that absorb vibration), and airtightness (effective seals to prevent sound leakage). In acoustic terms, adding mass and sealing the opening increases the transmission loss across the barrier.
Acoustic definition — transmission loss:
Transmission loss (TL), measured in decibels (dB), is the reduction in sound level as it passes through a barrier. Higher TL means a quieter room. Learn more about TL and decibels: transmission loss, decibel (dB).

Acoustic performance & data
Typical lab reports and installer measurements indicate:
| Shutter type | Typical dB reduction (real-world) | Perceived reduction |
|---|---|---|
| Basic aluminium single-skin | 6–12 dB | Noticeable; reduces mid/high frequencies |
| Insulated double-wall (foam core) | 12–30 dB | Significant — often described as “room-quieting” |
| Sealed + professional install | +3–8 dB improvement | Better low-frequency control and overall quietness |
Note: Lab figures are measured under controlled conditions (standardised methods) and often reported as octave-band data, Rw/STC, or TL. Real-world performance varies with gaps, wall construction, glazing, and background noise. For context on rating systems, see STC and Rw (sound reduction index).
What affects results in Perth homes
- Noise type: Traffic rumble and aircraft noise contain more low frequencies; these require higher mass and airtight seals.
- Existing window build: Thin glass and leaky frames allow flanking noise; sealing tracks and the headbox helps.
- Room layout: Corner rooms and hard surfaces reverberate; add soft furnishings for extra absorption.
Term — flanking paths:
Unintended routes noise takes around a barrier (e.g., gaps at frames, vents, or wall cavities). Closing these paths can transform performance.
Key features to look for
Material & profile
Double-wall aluminium slats with a polyurethane or polystyrene foam core offer an excellent balance of weight, rigidity, and damping. For improved low-frequency reduction (e.g., road rumble), look for thicker slat profiles and higher mass per metre. For help selecting the right profile, see our guide to roller shutter insulation benefits.
Sealing systems
Side brushes, rubber bottom seals, and a well-designed headbox greatly reduce sound leaks. Even a 3 mm side gap can cut performance by several dB. Read more about proper sealing and installation on our roller shutters installation tips page.
Motorisation & soft-close
Motorised shutters with soft-close and precise position control create a consistent seal every time, improving acoustic results and reducing wear compared with poorly aligned manual systems.
Finishes, durability & compliance
- Coatings: UV-stable powder-coated finishes resist fading in WA sun and coastal conditions.
- Corrosion resistance: For coastal suburbs, select marine-grade components and sealed fixings.
- Bushfire considerations: In bushfire-prone areas, confirm BAL suitability and installation details before ordering.
Requested acoustic evidence
Ask suppliers for octave-band test results or an AS/ISO-style acoustic report (e.g., ISO 10140-type data) so you can compare like-for-like. Also request the reported Rw/STC value for the shutter and any notes on installation assumptions.
Roller shutter types & specs
| Type | Core/Build | Best for | Acoustic notes |
|---|---|---|---|
| Single-skin aluminium | Hollow slat | Basic privacy, light control | Entry-level noise reduction; limited low-frequency performance. |
| Insulated double-wall | PU/PS foam-filled | Bedrooms, nurseries, shift workers | Great all-round reduction; strong thermal insulation. |
| Extruded heavy-duty | Thicker aluminium, higher mass | Busy roads, mixed-use streets | Improved low-frequency control due to added mass. |
| Smart motorised | Automated with soft-close | Routine schedules, remote control | Consistent seal every cycle; reduces user error and rattles. |
Installation & sealing — a step-by-step guide
- Measure precisely — order a custom fit, not off-the-shelf sizes.
- Mount guides plumb — misalignment creates gaps and rattles.
- Fit side brushes and bottom seals — they block air paths that carry sound.
- Seal headbox & wall junctions with high-quality acoustic silicone or sealant.
- Isolate fixings — use gaskets or sealant so screws don’t transmit vibration into the frame.
- Commission motor settings (if motorised) for soft, full closure without overloading.
- Verify balance — ensure even slat tension to prevent chatter in wind.
- Test and tune — compare before/after noise and address any remaining leaks.
Pro Tip: A professional installer with acoustic experience can outperform a basic install by 3–8 dB. If noise reduction is your top priority, the upgrade is worth it.
Benefits beyond noise
- Thermal performance: Foam-filled shutters reduce heat gain and heat loss, helping to lower cooling and heating loads. Find additional thermal tips in our energy-efficient window coverings guide.
- Security: Robust aluminium slats add a physical barrier and deterrent.
- Weather & storm protection: Durable profiles provide extra resilience in coastal or storm-prone areas.
- Privacy & blackout: Great for shift workers, nurseries, or media rooms.
- Energy efficiency & comfort: Less glare, more stable indoor temperatures, and better sleep hygiene.
Buying guide & pricing (Australia)
Pricing varies by size, motorisation, insulation level, and installation complexity. As a ballpark:
- Small window (1200 × 1000 mm) — from ~AUD 600–1,200 (basic).
- Insulated motorised shutter (large openings) — AUD 1,200–3,500+.
What drives cost
- Opening size & access: Upper-storey installs and wide spans add labour and materials.
- Motor & smart control: Automations, remotes, and smart-home integration increase price.
- Acoustic & thermal spec: Heavier slats, denser foam, and enhanced seals lift performance and cost.
- Finish & environment: Marine-grade upgrades for coastal homes prevent corrosion.

Case study — Australian suburban retrofit
Scenario: Single-storey townhouse near a busy arterial road. Measured external peaks ~78 dB at night. Installer fitted insulated double-wall shutters on three rear windows, with a sealed headbox and brush seals in the tracks.
Outcome: Post-install measurements showed ~15 dB reduction at the window face. Occupants reported fewer sleep disturbances and a 12–18% reduction in air-conditioning runtime during hot months.
Checklist — 5 steps before you buy
- Request specific dB or octave-band data for the exact product (and any Rw/STC rating).
- Confirm the installer’s experience with acoustic jobs (ask for references or photos).
- Get seal details in writing — side brushes, bottom seals, and headbox sealing.
- Compare motor vs manual: motorisation often improves seal consistency.
- Verify warranty terms and any required bushfire/coastal compliance.
People also ask
Are roller shutters good for traffic and aircraft noise?
Yes. Insulated, well-sealed shutters reduce road rumble and flight noise significantly, especially when paired with quality glazing and airtight installation.
Do roller shutters make rooms darker and cooler?
They provide blackout and strong thermal insulation. Bedrooms stay darker for longer, and indoor temperatures remain more stable through Perth summers.
Is motorised better than manual for noise control?
Motorised systems close evenly with soft-stop, creating a consistent seal. That usually means fewer gaps and better noise reduction day to day.
Can I retrofit roller shutters to existing windows?
Absolutely. Most homes can be retrofitted with minimal disruption. Correct measurements and sealing are the keys to a tidy, quiet result.
How do roller shutters compare to double glazing?
Glazing upgrades are excellent but costly. Shutters offer strong noise and thermal benefits plus security, often at a lower installed cost.
Frequently asked questions
Can roller shutters completely soundproof a room?
No. No retrofit will fully “soundproof” a room. However, quality insulated shutters with airtight installation can make a substantial difference (often 10–30 dB depending on conditions and existing window performance).
Does installation quality matter?
Yes. Proper sealing, plumb guides, and a correctly fitted headbox are critical. Poor installation can reduce performance by several dB and introduce rattles.
Are motorised shutters quieter?
Motorised systems with soft-close provide consistent closure and less slamming, improving perceived quiet and prolonging seal life.
Will shutters reduce low-frequency noise (bass)?
Low frequencies are the hardest to block. Heavier slat mass and airtight installation help, but for very strong bass (e.g., trucks, subwoofers) you may also need structural upgrades or enhanced glazing.
How long do roller shutters last and what maintenance is required?
Quality shutters often last 15–20+ years. Clean tracks twice a year, rinse coastal salt build-up, and schedule periodic checks on seals and motor settings.
With long-lasting quality and significant noise reduction, investing in roller shutters is the right choice for Perth homeowners. For even greater control and convenience, consider switching to smart residential shutters to maximise your comfort at home.
