Middle East Conflict Fuels Rising Costs for Australian Homes: Double Glazing Set to Become More Expensive

Australian homeowners looking to upgrade their windows and doors are likely to face a significant price increase, with experts warning that the ongoing conflict in the Middle East is driving up the cost of essential materials. The impact is particularly being felt in the double-glazing market, a popular choice for its durability and low maintenance.

The most common material used for modern double-glazed windows and doors is unplasticised polyvinyl chloride, or uPVC. This versatile plastic has been a staple in Australian households since the early 1980s, offering a cost-effective and long-lasting solution for home improvements. However, the intricate global supply chain means that geopolitical events thousands of kilometres away can have a direct and tangible effect on our hip pockets.

The Oil Connection: Why Global Tensions Hit Home Renos

At the heart of the issue lies the price of crude oil. The escalating tensions in the Middle East have disrupted crucial shipping lanes and led to a surge in oil prices, with benchmarks like Brent crude consistently trading above $100 a barrel. This price hike, while often associated with rising petrol and energy bills, has a cascading effect on a surprising range of industries, including home renovations.

The reason is simple: uPVC is a plastic polymer, and a significant portion of its composition is derived directly from petrochemicals, which in turn come from crude oil. It’s estimated that uPVC is used in a substantial percentage of replacement windows and doors across Australia, making it highly susceptible to fluctuations in oil markets.

Antony Heath, development director at Glevum Windows, explains, “When oil prices rise, the cost of producing those raw materials increases almost immediately.” This isn’t the only factor, however. The manufacturing process for uPVC frames and the toughened glass commonly used in windows and doors is incredibly energy-intensive. These materials require heating to extremely high temperatures in industrial furnaces, meaning that increased gas and electricity costs are inevitably passed on to the consumer.

Beyond Windows: The Wider Impact on Home Renovations

The ripple effect of rising oil prices extends beyond just windows and doors. Clive Holland, a broadcaster at Fix Radio, highlights the impact on electrical installations. “Most electrical cabling uses PVC for insulation and sheathing,” he notes. “So when petrochemical prices rise, cable costs follow.”

Adding to this pressure, copper prices, a vital component in electrical wiring, also tend to spike during periods of energy and market volatility. This dual increase in material costs for both insulation and conductors puts further strain on the final price of electrical work within a renovation.

Furthermore, as fuel prices climb, so do distribution and transportation costs. This affects every stage of the supply chain, from the initial sourcing of raw materials to the delivery of finished products to building sites and homes. The cumulative effect of these factors creates undeniable upward pressure on the overall cost of home improvements.

How Much More Will Homeowners Pay?

Experts anticipate a lag of a few months before the full impact of current oil price surges is reflected in renovation costs. However, initial indications are already pointing towards a notable increase. Based on current supplier guidance, prices for uPVC windows and doors are already reportedly around 8% higher than they were prior to the recent geopolitical escalations. This figure is dynamic, with suppliers continuously adjusting their pricing in response to ongoing oil market volatility.

For a homeowner considering replacing all the double-glazed windows in a typical semi-detached house, a project that might have cost around $4,500 earlier this year could now be looking at a price tag closer to $4,800 or more, depending on the specific specifications chosen. It’s important to note that some installers may still be working with older stock or previously agreed-upon pricing, so these figures are likely to become more uniform as time progresses.

If higher energy prices persist, a further increase of between 5% and 10% on uPVC window and door quotes is a reasonable expectation. This could translate to an additional $20 to $50 per standard installed window, or a total increase of $200 to $400 for a full-house job. The construction and renovation sector has already navigated significant material inflation in recent years, making this latest price adjustment consistent with previous cost cycles.

Supply Chain Resilience: Will There Be Shortages?

Despite the concerning price trends, experts generally agree that an immediate shortage of uPVC windows and doors is unlikely in Australia as a direct result of the current Middle East conflict. The industry has demonstrated a capacity to adapt and maintain supply even through major disruptions, such as the COVID-19 pandemic and the energy crisis that followed the conflict in Ukraine.

However, the longer the conflict continues, the more sustained the price increases are likely to be. While outright shortages are not anticipated in the short term, manufacturers may face increased pressure on their supply chains as they manage rising costs and logistical challenges. This could potentially lead to longer lead times for orders.

What Should Homeowners Do Now?

For Australian homeowners planning to invest in new uPVC windows or doors, it’s crucial to be aware of these potential price hikes. Replacing windows and doors is a significant financial undertaking, and it’s essential not to rush into a decision.

When looking for new windows and doors, consider the following:

Be Wary of “Too Cheap to Be True”: Extremely low prices can often indicate corners have been cut in terms of material quality or manufacturing standards. It might also suggest a company is not financially robust enough to weather market fluctuations.
Look for Added Value: Instead of solely focusing on the base price, consider installers who offer added value. This could include a wider range of colour options, enhanced security features, or even options like triple glazing.
Plan Ahead and Secure Your Price: While prices are expected to rise, some installers may offer the option to lock in current pricing if you place an order sooner, even if installation is scheduled for a later date. This can provide a degree of certainty in an unpredictable market.
Prioritise Quality and Longevity: Ultimately, windows and doors are a long-term investment. Focus on security, durability, and energy efficiency, as these factors will contribute to your home’s comfort and value for years to come.
