Double-glazed windows & doors in Hampton Park.
Hampton Park is the suburb where acoustic glazing usually drives the spec before thermal does. Between the Mulgrave Freeway, the Princes Highway and the Moorabbin Airport flight path overhead, single-glazed windows here aren't just bleeding heat — they're letting in road, traffic and aircraft noise all night.
The Hampton Park double-glazing story.
Three concurrent noise sources.
Mulgrave (Monash) Freeway: northern half of Hampton Park is within 1km. Traffic noise peaks 65–75 dB(A) at the property line on arterial-side facades.
Princes Highway / South Gippsland Highway: the southern arterial and the South Gippsland Hwy off-ramp generate a constant 24/7 traffic floor of 55–65 dB(A) on the facing facade.
Moorabbin Airport circuit + RPT/charter overflights: Hampton Park sits under one of the Moorabbin circuit-training tracks. Light aircraft and helicopters overhead are a low-frequency drone that single glazing essentially doesn't attenuate. We hear about this on 80% of Hampton Park site visits within the first 10 minutes.
Acoustic IGU spec — the maths.
Standard double-glazed IGUs (4mm + 4mm with 12mm argon cavity) achieve Rw 31–33 dB — barely better than single glazing for low-frequency aircraft drone. The acoustic-spec build uses asymmetric glass thicknesses (e.g. 6mm float + 10.38mm laminated) with an optimised cavity width — this breaks the coincidence-frequency resonance and pushes performance to Rw 38–42 dB. That's a perceived halving of noise — the difference between sleeping and not sleeping near the flight path.
Air-seal is half the acoustic performance.
A $3K acoustic IGU performs no better than the standard unit if the frame perimeter leaks air. We treat every Hampton Park acoustic install as a full air-seal job: closed-cell foam backing rod + acoustic sealant (not standard silicone) at the reveal-to-frame junction, fitted weather-stripping at every operable sash, and pressure-check at handover. Installer skill genuinely matters more than glass spec on acoustic jobs.
Thermal benefit comes free.
The acoustic-spec IGU is also a great thermal performer — the asymmetric laminated build typically delivers U ~1.6–1.8 W/m²K with a Low-E coating, so you get the heating bill drop alongside the noise reduction. VEU rebate still applies. That's why acoustic upgrades for Hampton Park are usually a no-brainer on bedrooms and living rooms — extra $2K–$3K per window for a perceptual halving of noise + thermal.
