Introduction: The Importance of Choosing the Right Windows
Windows are not just an architectural feature that adds aesthetic value to your home. They also have a significant impact on your home’s energy efficiency, and consequently, your energy bills. As the energy costs continue to soar, it’s crucial to understand how up to 40% of heat energy can be lost through inefficient windows. That’s where double glazed windows come into play, offering a smart solution to reduce energy costs.
What Are Double Glazed Windows, and How Do They Function?
Double glazed windows consist of two panes of glass separated by a spacer, often filled with argon gas, to create an insulated barrier. The space between the glass is at least 12mm and hermetically sealed, acting as a thermal break that hampers the heat transfer between the external and internal glass panes. As a result, these windows can cut down heat loss or gain by up to 30%, making them highly energy-efficient compared to single-glazed windows.
Much like the insulation properties of woollen clothing, double glazing traps air between its two layers. Glass is a good heat conductor, while air is a poor one, and this trapped air thus acts as a form of insulation, making these windows incredibly efficient for heating and cooling purposes.
Single Glazed vs Double Glazed Windows: A Comparison
In contrast to a double glazed window, a single glazed window consists of only a single pane of glass, providing inadequate insulation and allowing for considerable heat loss or gain. Double glazed units are laminated or tinted but are fundamentally similar to single glazed windows, except for the critical difference of the argon gas filled space offering better insulation.
The Pros and Cons of Double Glazing
Benefits of Double Glazing
- Energy-efficient: Cuts down on energy bills
- Environmentally friendly
- Effective noise reduction: Reduces outside noise
- Durable with low maintenance requirements
- Increases property value
- Reduced condensation and mould buildup
While double glazing is incredibly efficient at retaining heat, this can be an issue during the hotter months. To mitigate this, consider using low-e glass or UV protective coatings, although these options will increase your initial costs.
Installation: What You Need to Know
When it comes to installing double glazed windows and doors, it’s advisable to consult professionals. Installation impacts the windows’ performance significantly and should never be a D.I.Y. project. The process may involve re-plastering, redecorating, and even refitting your curtains and blinds. Speak to a professional installer to discuss your double glazing options and request a free site meeting in Sydney or across Australia.
Design Considerations for Your Double Glazed Windows
For optimal noise reduction, focus on sealing gaps and cracks around your windows. Double glazed windows already offer significant noise reduction, especially when combined with acoustic glass.
Fading and Sunlight
Exposure to sunlight can fade your interior furnishings over time. High-quality double glazing can reduce this effect.
Double glazing can significantly reduce the amount of condensation that builds up on the windows, enhancing the inside of your home.
Though the initial costs might seem higher, double glazed windows offer long-term savings by reducing your energy bills, thereby offering peace of mind.
Pricing: What to Expect
The average cost for installing double glazed windows in Sydney or across Australia is around $800 per square metre. This price can vary based on your specific needs and location. However, the long-term energy savings make it a worthwhile investment.
While the initial costs may be high, the long-term benefits of double glazing, such as reduced energy costs and noise pollution, make it an excellent investment for your Sydney home. From thermal efficiency to added comfort, double glazed windows are a smart choice for anyone looking to save on energy costs while enhancing the style and performance of their home.
