Understanding Price, Value, and What Really Affects the Cost
If you’re considering upgrading your home with double glazed windows in Perth, you’ve likely noticed that prices can vary widely. So, how much do double glazed windows cost in Perth, and why?
The answer depends on more than just materials. The real story is about value — how quality double glazing enhances comfort, energy efficiency, and long-term savings.
At Canon Double Glazing Perth, we believe an informed homeowner makes the best investment. This guide explains the factors, pricing expectations, and ballpark costs so you can plan confidently and avoid surprises.
Why Double Glazing Prices Vary
No two Perth homes — or windows — are exactly alike. The double glazing cost for your project depends on several factors:
- Window size and configuration: Larger openings or complex window styles such as sliding windows, awning windows, and double hung windows increase materials and labour time.
- Glass type: Low-E glass, acoustic glass, and tinted options improve thermal efficiency and noise reduction but cost more than standard double glazing.
- Frame materials: UPVC frames offer excellent insulation and low maintenance, while aluminium or timber frames may increase the overall price.
- Existing window frames: If your existing windows and frames are sound, retrofitting can be more economical than full replacement.
- Installation complexity: Multi-storey homes, difficult access, or structural modifications affect total labour costs.
- Project scale: A single replacement window costs more per unit than a full-house upgrade, where volume brings better value.
In short: while double glazing isn’t the cheapest upfront upgrade, it’s one of the most rewarding over the long term — lowering energy bills, improving comfort, and enhancing your home’s appeal.
What You’re Paying For: Beyond the Glass
Quality Materials
High-performing double glazed units use two panes of glass separated by an insulating gap filled with air or an insulating gas such as argon. This creates a sealed thermal barrier that minimises heat loss in winter and heat gain in summer.
Choosing quality double glazed windows with properly sealed edges, tested gas fills, and durable frames ensures years of consistent performance.
Expert Craftsmanship
Installation quality matters as much as the glass. A poorly sealed window frame can negate your energy efficiency gains. Canon’s qualified installers ensure precision fits, airtight seals, and full structural integrity for lasting comfort.
Energy Efficiency and Savings
Though double glazing has a higher upfront cost than single glazing, the energy savings quickly add up. Homeowners often reduce heating and cooling costs by 30–60% over time, meaning your windows effectively save money every day.
Ballpark Estimates: What Perth Homeowners Can Expect to Pay
To give you a practical sense of pricing, here are realistic cost ranges based on current Perth market averages. These figures are intended as a planning guide, not fixed quotes.
| Upgrade Type | Typical Price Range (Perth) | Includes |
| Retrofit (Glass Only) | $300 – $500 per m² | Replaces old single glazing with new double glazed units while keeping existing window frames intact. Ideal for homes in good condition. |
| Full Replacement (uPVC Frames) | $600 – $1,000 per m² | Complete removal of existing windows, supply and install of new double glazed windows with UPVC frames and modern seals for improved thermal efficiency and low maintenance. |
| Standard 3-Bedroom Home (Full Upgrade) | $15,000 – $25,000+ | Whole-house installation covering 15–20 glazed windows and doors, professional installation, and warranty-backed components built for WA conditions. |
Note: Final prices vary depending on glass type, frame colour, access conditions, and hardware. Always request a transparent quote with no hidden fees.
These ballpark estimates help homeowners budget realistically and compare quotes confidently — ensuring you get the right balance between quality and cost.
The Real Cost Equation: Long-Term Value
The cost of double glazing should always be weighed against its lifetime performance. High-quality systems reduce energy bills, lower cooling costs, and improve your home’s energy efficiency — translating to thousands of dollars saved over the years.
Beyond energy savings, you gain year-round comfort, quieter interiors, stronger security, and a low-maintenance upgrade that enhances your home’s value in the long run.
Perth Conditions and Local Manufacturing
Perth’s climate — with harsh sunlight, sea breezes, and big temperature swings — demands glazing built for local conditions. Locally made double glazing ensures materials, coatings, and seals are suited to Western Australia’s environment.
Canon Double Glazing’s new double glazed units are manufactured in Perth using quality materials designed to last — ensuring performance, insulation, and aesthetic appeal for years to come.
Common Questions About Double Glazing Costs
Does window style affect the cost?
Yes. Awning windows, sliding windows, and double hung windows differ in frame materials and hinges, which influence pricing.
Can double glazing be installed into existing frames?
Often yes. If your existing frames are in good condition, we can retrofit new double glazed units or use secondary glazing methods to reduce costs.
What if I’m on a budget?
Canon offers transparent quotes with interest-free payment plans to make upgrades manageable.
Are there hidden fees?
No. All quotes include installation, materials, and removal of old windows — no hidden fees or unexpected charges.

For Perth homes, double glazing isn’t just a comfort upgrade — it’s a smart financial decision.
