Double glazed windows have become a cornerstone of modern Australian homes, offering unparalleled benefits in energy efficiency, noise reduction and security. If you are planning to install double glazed windows, then here is a Complete Guide To Double Glazed Windows for you.

Introduction To Double Glazed Windows:

Double glazed windows consist of two layers of glass with a space between them. This space can be filled with air or an inert gas, such as argon or krypton. The two glass panes and the gas layer work together to create an insulation barrier that significantly improves the window’s thermal efficiency.


How Do Double Glazed Windows Work?

The principle behind double-glazed windows is simple yet highly effective. The two panes of glass, combined with the gas-filled gap, act as a thermal barrier. This barrier reduces the amount of heat that can pass through the window. In winter, it keeps warm air inside and in summer, it blocks a significant portion of the heat from entering the home. The inert gas in the gap is denser than air, providing better insulation. Additionally, treatments on the glass, such as low-E coatings, can reflect heat into the room, enhancing the window’s thermal efficiency.

Is Double Glazed Window Really Effective?

  • Insulation Layer: The double glazed windows consist of a gap between the two panes of glass. This gap is essential for providing superior thermal insulation. By creating a barrier against the outside temperature, this insulation layer helps maintain a comfortable indoor climate, irrespective of the weather conditions outside. The choice of gas, such as argon or krypton, further enhances this insulating effect due to their lower thermal conductivity compared to air.
  • Sealed Unit: The effectiveness of a double glazed window hinges on the integrity of its seal. Airtight sealing around the perimeter of the window unit prevents the ingress of moisture and the escape of the insulating gas contained within the gap. This sealing is crucial for preserving the window’s insulating ability over time, ensuring that it continues to perform at its peak efficiency.
  • Glass Types: The type of glass used in double glazed windows can significantly impact their thermal performance and functionality. Low-emissivity (low-E) glass is coated with a thin metallic layer that reflects heat into the room, minimising heat loss while still allowing natural light to enter. Other glass options may include tinted glass to reduce glare and solar gain, and toughened or laminated glass for enhanced safety and security.
  • Frame Materials: The choice of frame material plays a pivotal role in the window’s overall thermal efficiency, durability, and appearance. uPVC frames are popular for their excellent insulation properties, low maintenance and resistance to weathering. Wood frames offer a classic aesthetic and good insulation but require more upkeep to prevent weather damage. Aluminium frames are durable and slimline, offering a modern look with good thermal performance when equipped with a thermal break.

Benefits of Double Glazed Windows

  • Energy Efficiency: One of the most significant advantages of double-glazed windows is their ability to reduce heat transfer. This means less energy is required to heat or cool the home, leading to lower energy bills and a smaller carbon footprint. The improved insulation helps in achieving a more energy-efficient home, contributing to environmental conservation efforts.
  • Noise Reduction: For those living in busy urban areas or near noisy environments, double-glazed windows can dramatically improve the quality of life by reducing the amount of external noise that enters the home. The dual panes of glass and the insulating gap act as a sound barrier, creating a quieter, more peaceful indoor environment.
  • Enhanced Security: The additional pane of glass in double glazed windows makes them more difficult to break than their single-glazed counterparts. This enhanced security feature provides homeowners with added peace of mind, knowing their home is better protected against potential break-ins.
  • Condensation Reduction: Condensation on windows can lead to mould growth and damage to the window frames and surrounding areas. Double-glazed windows help in reducing condensation by maintaining the inner glass pane at a temperature closer to the indoor air, thereby minimising the conditions that lead to condensation buildup.

Double-glazed windows offer a comprehensive solution to modern living requirements, combining energy efficiency, comfort and security into a single investment. Whether you’re building a new home or upgrading your existing windows, considering the key features and benefits of double-glazed windows can help you make an informed decision that will contribute to a more sustainable, comfortable and secure living environment.

Introduction to Decision Making: DIY vs. Hiring a Professional
