A Practical Guide to Making Your Perth Home Quieter

A Practical Guide to Making Your Perth Home Quieter

Perth is changing. Urban developments are reshaping older suburbs, freeway upgrades keep traffic flowing (and humming), train services are busier, flight paths shift with the seasons, and weekend life in Northbridge, Leederville, and Subiaco rarely sits still. Add the Fremantle Doctor pushing wind through every little gap in summer and the result is the unwanted outside noise that can creep into your living room, bedroom and home office more than you’d like.

If you’ve found yourself turning up the TV, sleeping with earplugs or waking earlier than you’d prefer thanks to early traffic or bins day, you’re not alone. The good news: you don’t need a major renovation to reclaim the quiet. With the right combination of interior tweaks, smart sealing and targeted window upgrades, you can effectively reduce noise while improving overall comfort – summer and winter.

Below is a practical, Perth-ready plan that will provide immediate results and works for everything from heritage homes in Fremantle and Mount Lawley to coastal apartments in Scarborough and new builds in the northern corridor.

Start Inside: Tame Echo and “Room Noise”

A surprising amount of perceived noise is created inside the home. Hard surfaces – timber or tiled floors, large panes of glass, plasterboard walls, high ceilings – bounce sound around. Conversations feel louder, clatter lingers and even modest outside noise seems amplified.

Begin by softening the room. In open-plan spaces, add a dense rug with a quality underlay (the underlay does more acoustic work than most people expect). Swap light sheers for lined curtains or layer blinds with drapery; in Perth, this also helps with glare and late-afternoon heat. Introduce upholstered pieces, cushions and book-filled shelves to break up reflections. In small offices or media rooms, two or three discreet acoustic panels (or acoustic art) placed at typical reflection points can make a big difference. These changes reduce reverberation, helping outside noise fade into the background rather than reverberate through the space.

Rearrange for Acoustic Advantage

Next, use what you already own as sound buffers. Think mass and position. Full bookcases or tall storage units on street-facing or neighbour-adjoining walls add weight and dampen transmission. If a bedroom faces a busy road, pull the bedhead off the external wall and shift the bed slightly away from the window line if the room allows. In open-plan areas, zone with high-back sofas or sideboards to create quieter pockets for calls, study or reading.

Small adjustments matter: a high-back chair in the right spot can shield you from a specific noise path. Door sweeps or simple seals on internal doors (bedrooms, studies) reduce sound transfer between zones, useful when one person rises early or works late.

Stop Sound at the Gaps (and Cut Draughts While You’re There)

Noise loves shortcuts. Tiny gaps at window sashes, sliding door tracks and architraves act like miniature loudspeakers. If air moves, sound moves. On a breezy afternoon (the Fremantle Doctor is a perfect test), run your hand around frames and sills to feel for leaks. Those are your priority points.

Quality weather and acoustic seals on hinged and sliding windows/doors can sharply reduce both noise and draughts. Treat the small culprits too such as pet doors, exhaust vents and downlight penetrations. Where practical, add covers, baffles or dampers. The payoff is twofold: less whistle and rumble on windy days, plus a tighter, warmer home on cool nights, handy for those winter fronts that roll through Perth.

If you have older sash windows or big aluminium sliders (very common locally), purpose-made sealing systems can improve performance without changing how the window operates or how the façade looks. Sealing is also one of the most budget-friendly noise upgrades you can make, and it prepares the ground for the highest-impact change of all: improving the glazing.

Tackle the Weakest Link: Upgrade the Windows (Without Replacing Them)

Windows are usually the thinnest part of your home’s envelope. Single panes transmit airborne noise easily and shed conditioned air quickly – two issues that show up as living near freeways or rail, dealing with airport traffic in Redcliffe/Ascot/South Guildford or simply trying to keep a coastal home calm on windy evenings.

An effective, low-disruption fix is retrofit double glazing windows solutions. Rather than ripping out the existing window, a custom secondary window system is installed to the inside of your windowsill with an optimum air cavity, transforming your single glazed window into a double glazing. That air cavity is the key: it impedes sound transmission and acts as a thermal buffer. In practice, homeowners typically experience a substantial reduction in outside noise (often quoted up to 70%, depending on window type and installation), fewer cold drafts in winter and a noticeable drop in late-afternoon heat gain, especially on west and north-facing glass.

Retrofit suits Perth housing stock particularly well. Large aluminium sliders and stackers, common in modern builds and coastal properties, are expensive to replace; retrofitting adds performance without touching the frame or finishes. In character pockets (Fremantle, Mount Lawley, Shenton Park), upgrading from the inside preserves street appeal and satisfies heritage sensitivities. And because installation is faster and cleaner than full replacement, disruption is minimal often measured in hours, not weeks.

Pairing retrofit glazing with well-fitted seals around operable parts delivers the biggest step-change in quiet and comfort for most homes.

Room-by-Room Priorities for Perth

Street-facing bedrooms.
Start here for the most immediate lifestyle win. Retrofit glazing, lined curtains and door seals transform sleep quality. If you face an arterial or bus route (e.g., near Thomas Street, Canning Highway or Wanneroo Road), prioritise these rooms first.

Home office.
For hybrid workers, calm equals focus. Retrofit the primary window, add a rug with underlay, and seal the door. One or two acoustic panels at reflection points (behind or beside your monitor) can take the “edge” off calls.

Living areas near corridors.
If you back onto rail or sit close to the Mitchell/Kwinana corridors, target the largest panes first. Retrofit glazing reduces the baseline rumble, while textiles manage the room’s echo.

Coastal rooms.
The Fremantle Doctor brings airflow and sound. Sealing reduces wind-borne noise and dust; glazing stabilises temperature and quiets evening gusts. Consider adding solar-control film to west-facing glass to address heat and glare.

What Results Should You Expect?

Every home is different but patterns emerge. After these changes, most Perth homeowners report that traffic, aircraft and neighbour noise shift from “constant intrusion” to “background texture.” Bedrooms become restful again. The whole house feels calmer because echoes are tamed and leaks are sealed. You may also find the HVAC system runs less often: rooms hold temperature longer after the air-con cycles off and winter mornings feel less stark. With retrofit glazing, many notice far less condensation on cool nights, which helps protect frames and paintwork.

The goal isn’t silence. It’s control i.e. dialling down the noise to a level that makes life at home easier, kinder and more comfortable.

A Simple Plan (Phase It In)

This weekend: add a dense rug and lined curtains to your noisiest room; re-arrange furniture to buffer a street-facing wall; install adhesive door sweeps on bedrooms/studies.
This month: fit quality weather/acoustic seals on key windows and sliders; list your worst-affected rooms (bedrooms first).
This year: retrofit double glazing windows and doors in stages, starting with sleep and work zones, then move to main living areas. Layer in solar-control film on harsh west-facing glass where heat and glare bite.

This phased approach keeps costs manageable and lets you feel the gains at each step.

The Bottom Line

You can’t control Perth’s growth or the noise that comes with it but you can control how your home responds. Soften the room to stop echo. Seal the gaps to block shortcuts. Then upgrade the glazing, the single biggest improvement for lasting quiet and comfort. Done together, these moves create a calmer, more energy-efficient home that works with Perth’s climate and lifestyle rather than against it.

  1. Conduction
    Heat moving through an object (i.e. heat will travel through an aluminium, or steel frame more easily than through a timber or PVC frame).
  2. Radiant heat
    Heat from the direct sun. It can pass through space until reflected or absorbed.
  3. Convection
    Heat flow resulting from air movement e.g. either 'natural' convection - warm air rises, or 'forced' convection - a breeze by a window, both can result in a draught by a window.
  4. Infiltration
    Air leaks around the frame, around the window sash and through the gaps in the movable window parts.

When evaluating your options to improve the thermal performance of your windows, the following double glazing key performance criteria should be considered:

  • U-Value (Uw) represents heat transfer through a window, irrespective of direct sunlight. The lower a window’s U-Value, the better the insulation performance.
  • Solar Heat Gain Coefficient (SHGC) measures the solar energy that passes through glazing. The lower the SHGC, the less solar heat is transmitted through a window.
  • Air Infiltration or leakage measures the rate at which air passes through gaps in window joins and seals. The lower the air infiltration, the better a window’s energy performance.

Magnetite vs Traditional Double Glazing – What the experts says

Winter - the ideal situation is to let in as much of the sun's heat and then trap it inside to maintain a comfortable environment in your home or office. This will also significantly reduce heating costs and saves you money. The ideal window for winter will have a high SHGC to let the sun's heat in and a low U-Value to prevent the heat from escaping. Clear windows without shading films are better suited for winter climates.

Compared with traditional double-glazing, Magnetite’s double-glazing solution can provide better results during winter or for cold climate areas such as Canberra, the Adelaide Hills and Blue Mountains.

Magnetite's clear acrylic window panels allow the direct heat from the sun's rays to enter the building and once inside, Magnetite's superior magnetic seals retain the heat, giving Magnetite an advantage over conventional operating windows.

Summer - the ideal situation is to minimize the heat coming in from outside and prevent the cool air inside from escaping through the window. This will make your home more comfortable and reduce your air-conditioning costs. The ideal window for summer, or for a large west-facing window, will have a low SHGC to limit the heat from the sun's direct rays, as well as, a low U-Value to prevent the heat in the air outside from moving through the window and warming the cool conditioned air inside. It is better to have a shading film on the first (outer) glass pane to limit the heat that enters the double glazed unit.

The combination of Magnetite retrofit double glazing and Solartite outperforms the traditional insulated glass unit for hot climate. Magnetite fit over an existing window with reflective film will give better summer heat control than a double-glazed window with supertoned glass.

The Magnetite system stops the conduction and convection of heat better than glass windows giving superior results for summer conditions. Combined with a film or a shading device, Magnetite is the ideal solution for the hot Australian conditions.

Noise Reduction Technical Data and Results

Proven Results

Noise pollution is one the biggest problems faced in the cities today, particularly in a high-density living. Unwanted noise can be responsible for sleep loss and lack of concentration. This can lead to a deterioration of health through increased stress levels, headaches, high blood pressure and loss of hearing.

Noise penetrates windows through leaky seals or vibrations through the window structure. To reduce noise, a window should minimise air infiltration, hold enough weight to limit vibration and allow a large air cavity. This cavity, or air gap, is the key to secondary glazing.

Expert Advice:

CSIRO Research by John Davy shown an air cavity can effectively enhance sound insulation performance. The larger the air cavity the more noise the window system can reduce. Results show a wide air gap of 100-125mm will improve sound insulation by an average of 7dB(A) more than windows with a narrow gap of 8-13mm.

Window or Glass Door Type Total Glass Thickness (mm) Air Cavity Thickness (mm) Sound Insulation (dB)
Single Glaze 3mm 3 0 23
Single Glaze 6mm 6 0 27
Double Glaze Narrow Gap 9-12 8-13 31
Double Glaze Wide Gap 9-12 100-125 38

 

The human ear is less sensitive to low frequency sound. According to a study released by the CSIRO, the human ear needs a change of 3dB to detect a difference in noise levels and the human ear perceives a change of 10dB as a doubling or halving of the noise level.

If you double the thickness of glass in a window the noise level will decrease by 3dB the least amount possible to make a difference. If the glass is laminated there is no perceived difference in noise reduction.

National Acoustic Laboratory Testing:

Working with the principles of noise transfer, Magnetite® and Soundtite are designed for high performance, which is achieved by combining air tight seals with the ability to maximize an air cavity and the flexibility to vary glazing thickness to suit. Magnetite® is excellent at reducing general noise such as busy roads, commuter trains and noisy neighbours. Whereas, Soundtite works well to combat low frequencies noise such as garbage truck, freight trains or airplane during take-off and landing.
