By Penot Double Glazing
The northern suburbs are one of the fastest-growing double glazing markets in Perth. Three factors combine: the housing stock is now old enough to need glazing upgrades (1980s and 1990s subdivisions reaching the 30 to 40 year mark), the climate runs hotter inland from the coast, and the Mitchell Freeway corridor delivers consistent road noise to properties across a wide band.
This guide covers the double glazing considerations specific to Perth’s northern suburbs: the housing stock by era, the Mitchell Freeway noise corridor, the inland Wanneroo heat profile, and the practical question of how the Bayswater showroom services northern corridor properties. Drawn from City of Joondalup and City of Wanneroo data, confirmed Main Roads WA noise criteria, and Bureau of Meteorology Perth climate observations.
Why the Northern Suburbs Are a Growing Double Glazing Market
The northern corridor of Perth saw three major waves of residential development that now line up for thermal upgrades.
1970s and 1980s wave. Duncraig and Padbury developed primarily in the 1970s and 1980s. The first wave of subdivision pushed development out from Greenwood north to Kingsley and Padbury. Brick veneer construction, aluminium-framed single glazed windows, tile roofs. These homes are now 35 to 50 years old and the original glazing is at the end of its expected service life.
1980s to 1990s wave. Hillarys, Sorrento, Mullaloo and Kingsley followed in the 1980s and 1990s. Same construction pattern, same single glazed aluminium frames.
1990s to 2000s wave. Currambine, parts of Joondalup itself and the outer Wanneroo corridor developed from the 1990s into the 2000s. Slightly improved glazing standards but still pre-NCC 2022 7-star compliance.
For a wider double glazed windows Perth refurbishment in any of these areas, the spec choice depends on the era of the home and the orientation profile. Earlier waves typically have smaller window proportions; later waves have larger glass areas.
The Bayswater Showroom and the Northern Suburbs
Penot Double Glazing operates from a single showroom at 92 Beechboro Rd S, Bayswater WA 6053. From the northern suburbs, the showroom is accessible via Mitchell Freeway and Tonkin Highway routes:
- From Joondalup: approximately 30 to 40 minutes by car
- From Currambine: approximately 30 to 40 minutes
- From Hillarys and Sorrento: approximately 25 to 35 minutes
- From Duncraig and Greenwood: approximately 20 to 30 minutes
- From Padbury and Kingsley: approximately 25 to 35 minutes
- From inland Wanneroo: approximately 35 to 45 minutes
All consultations happen at the customer’s home rather than the showroom, so the assessor sees the actual rooms, orientations and surrounding finishes before quoting. The showroom visit is optional and useful for homeowners who want to see frame finishes, glass samples and hardware up close before booking the consultation.
Housing Stock in the Northern Corridor and Which Products Suit
The dominant housing type across the northern suburbs is brick veneer with aluminium-framed single glazed windows. The window replacement pattern for these homes is straightforward:
Frame system. Thermally broken aluminium is Penot’s standard offering for the northern suburbs market. The thermal break drops the frame U-value from around 6.6 to around 2.2 W/m²K, delivering meaningful thermal performance from an aluminium system that suits the area’s predominantly brick veneer housing stock.
Glass spec by orientation. Solar-control low-e on west and unshaded north openings (SHGC 0.20 to 0.40). Standard double glazed on south openings (clarity and U-value, less SHGC priority). Acoustic laminated outer pane on freeway-facing or rail-corridor-facing openings.
Frame finish. Standard Dulux powder-coat range covers most home aesthetics. Custom colour and woodgrain foil options for premium finishes.
Project size for a typical 1980s northern corridor brick veneer: 12 to 16 windows plus 1 to 2 doors, running $26,000 to $48,000 supply and install for a quality thermally broken specification. Our hidden cost of single glazed windows guide covers the cost-of-inaction analysis behind the upgrade decision.
Mitchell Freeway Noise: Which Suburbs and How Much
The Mitchell Freeway runs from the CBD north through Joondalup, with the freeway corridor affecting properties within 200 to 300 metres of the road in varying degrees depending on noise wall coverage and property setback.
Main Roads WA confirmed a 60 dB(A) noise criterion in the Tonkin Gap Project FAQ, which is the design target at the property facade for new freeway works. Existing freeway corridor noise levels on Mitchell can reach 65 to 70 dB(A) at the property line in pockets without effective noise walls.
Most exposed northern suburbs:
- Eastern Duncraig (streets backing the freeway corridor)
- Parts of Greenwood and Warwick
- Eastern Padbury (close to the freeway)
- Eastern Kingsley
Acoustic performance depends on the complete window specification and installation. Ask for test data for the configuration being quoted. The Penot Double Glazing flight path noise reduction page covers the acoustic specifications in detail. Our double glazing near Perth Airport and busy roads guide walks through the full acoustic case for road-noise-affected homes. Homeowners can check the Airservices Australia aircraft noise monitor to confirm their property’s exposure to flight paths.
Joondalup Railway Line Noise
The Mandurah / Joondalup railway line runs parallel to Mitchell Freeway for much of its length, with stations at Stirling, Glendalough, Leederville, Joondalup and Currambine among others. Acoustic performance depends on the complete window specification and installation. Ask for test data for the configuration being quoted.
Acoustic glazing on rail-corridor-facing windows is worth the cost premium for properties within 200 metres of the corridor.
Wanneroo Heat Profile: Why Inland Northern Suburbs Run Hotter
Inland Wanneroo (north of Joondalup, east of Mitchell Freeway) sits 15 to 20 km from the coast at its eastern edge. This distance matters because Perth’s Fremantle Doctor sea breeze, which provides afternoon cooling for coastal suburbs, takes longer to reach inland Wanneroo and arrives at lower intensity.
The practical effect: on extreme heat days (40-degree days, of which Perth Metro averages 5 per year per Bureau of Meteorology), inland Wanneroo can run 2 to 5 degrees warmer than Hillarys or Sorrento. The Fremantle Doctor arrives 1 to 3 hours later inland. By the time the breeze reaches eastern Wanneroo in late afternoon, the radiant solar load on west-facing rooms has already cooked the building envelope.
For inland Wanneroo properties, SHGC matters more than U-value for west and unshaded north windows. Solar-control low-e double glazing is the high-value spec. For very large glass areas on west-facing alfresco connections, triple glazing or external shading is part of the answer alongside the glass spec. Our does double glazing keep Perth homes cooler in summer guide covers the thermal physics behind the SHGC priority.

Where Is Penot Double Glazing’s Showroom Relative to the Northern Suburbs?
The Penot Double Glazing showroom is at 92 Beechboro Rd S, Bayswater WA 6053. From Joondalup it is approximately 30 to 40 minutes by car via Mitchell Freeway. From inner northern suburbs like Duncraig and Padbury it is 20 to 30 minutes. All consultations happen at the customer’s home rather than the showroom, so the assessor sees the actual rooms before quoting.
Is the Northern Suburbs Heat in Perth Different to Coastal Suburbs?
Yes, particularly for inland Wanneroo. Northern Wanneroo sits 15 to 20 km from the coast, which delays the Fremantle Doctor sea breeze by 1 to 3 hours and weakens its cooling effect. On extreme heat days, inland northern suburbs can run 2 to 5 degrees warmer than coastal Hillarys or Sorrento. SHGC on west and unshaded north windows matters more for inland properties.
What About Mitchell Freeway Noise on Northern Suburbs Homes?
Properties within 200 to 300 metres of Mitchell Freeway can experience 60 to 70 dB(A) noise at the property line, particularly without noise walls. Eastern Duncraig and parts of Greenwood and Padbury sit close to the corridor. Acoustic performance depends on the complete window specification and installation. Ask for test data for the configuration being quoted.
Which Councils Cover the Northern Suburbs?
City of Joondalup covers Duncraig, Hillarys, Sorrento, Currambine, Kingsley, Mullaloo, Padbury and Joondalup itself (22 suburbs total). City of Wanneroo covers Wanneroo and 35 other suburbs from Two Rocks to Koondoola. City of Stirling covers parts of the inner northern corridor.
