adminDouble glazed windows are an excellent choice for homeowners looking to improve their home’s energy efficiency, security, and comfort. They provide several advantages over traditional single-glazed windows, making them a popular option for new builds and renovations.
This article explores the features and benefits of double glazed windows in detail, outlining why they are an ideal investment for many Australian homes.
What Are Double Glazed Windows?
Double glazed windows are constructed with two panes of glass separated by a gap that is typically filled with an insulating gas such as argon or krypton. These windows are designed to provide better insulation, noise reduction, and security compared to single-glazed windows.
- Two Glass Panes: The two glass panes offer better insulation than a single pane, preventing heat loss and reducing noise.
- Spacer Bar: The spacer bar keeps the two panes separated, ensuring that the gap remains uniform. This gap is crucial for improving the window’s insulation properties.
- Insulating Gas: The gap between the two glass panes is filled with a non-conductive gas that significantly reduces heat transfer between the inside and outside.
- Sealed Unit: The entire unit is sealed to prevent moisture and air from entering the gap, ensuring longevity and optimal performance.
Features Of Double Glazed Windows
Double glazed windows have several distinctive features that make them an effective and efficient solution for homes. These features enhance comfort, security, and energy efficiency.
1. Thermal Insulation
One of the primary features of double glazed windows is their ability to provide superior thermal insulation. This is achieved through a combination of factors:
- Two Glass Panes: The space between the two panes of glass serves as a barrier to heat transfer. This helps to retain heat during winter and prevent excessive heat from entering in summer.
- Insulating Gas: The gap between the panes is filled with gases such as argon or krypton, which are poor conductors of heat. These gases help to further reduce heat transfer, maintaining a comfortable indoor temperature.
- Low-E Coatings: Many double-glazed windows feature low-emissivity (Low-E) coatings that reflect heat into the room during winter. These coatings also help keep the house cooler during the summer months by reflecting heat away.
2. Noise Insulation
Another key feature of double glazing is its ability to significantly reduce noise. Whether you live near a busy street, in an urban environment, or close to an airport, double glazing can help minimise the intrusion of external noise.
- Soundproofing Barrier: The two panes of glass and the insulating gas between them create a sound barrier that reduces the transmission of noise.
- Gas Absorption: The insulating gas, typically argon, absorbs sound vibrations, making it more difficult for noise to travel through the window.
- Glass Thickness: Thicker glass panes offer better noise reduction. In areas with high levels of external noise, laminated or acoustic glass can be used to further enhance soundproofing.
3. Improved Security
Double glazed windows offer added security over traditional single-glazed windows due to their construction and the materials used.
- Stronger Glass: The two panes of glass make it much harder for intruders to break through. The added strength of double glazing makes it more resilient to impact than single-glazed windows.
- Multi-Point Locking Systems: Many double glazed windows are equipped with multi-point locking systems that secure the window at multiple points. This adds an extra layer of security, making it harder for burglars to force the window open.
- Sealed Unit: The sealed construction of double glazing also makes it more difficult for intruders to tamper with the window, as the glass is firmly held in place.
4. Durability And Low Maintenance
Double glazed windows are designed to be durable and long-lasting. The materials used in their construction ensure they require less maintenance compared to single-glazed windows.
- Toughened Glass: The glass used in double glazing is typically tougher and more durable than that used in single glazing. This makes it less likely to break or become damaged over time.
- Low Maintenance: Double glazed windows require less maintenance than single-glazed windows, as they are less prone to condensation and moisture damage. The sealed unit design also prevents the accumulation of dirt and grime inside the window.
Benefits Of Double Glazed Windows
In addition to their features, double glazed windows offer numerous benefits for homeowners, ranging from energy efficiency to noise reduction and improved comfort.
1. Enhanced Energy Efficiency
Energy efficiency is one of the most significant benefits of double glazed windows. These windows help to reduce the need for heating and cooling systems, leading to lower energy consumption and reduced utility bills.
- Improved Insulation: Double glazed windows reduce heat loss during the winter months by preventing warm air from escaping. This means less reliance on heating systems, reducing overall energy consumption.
- Lower Cooling Costs: During summer, double glazing helps to keep the heat outside. By preventing heat from entering your home, these windows reduce the need for air conditioning, which leads to lower cooling costs.
- Long-Term Savings: Although the initial investment in double glazed windows may be higher than single glazing, the energy savings over time can offset the upfront cost. Homeowners can expect to see reduced heating and cooling bills, leading to long-term financial benefits.
2. Noise Reduction
For many homeowners, noise reduction is a significant factor in choosing double glazed windows. These windows are particularly useful for those living in noisy urban areas, near busy roads, or close to construction zones.
- Significant Soundproofing: Double glazed windows can reduce external noise by up to 70%. This creates a quieter living environment, making it easier to relax, work, and sleep without the disturbance of outside noise.
- Improved Privacy: In addition to blocking external noise, double glazed windows also help to keep the sound from leaving your home. This means that conversations and other noises inside the house are less likely to be heard by neighbours, providing enhanced privacy.
3. Improved Comfort
Double glazed windows contribute to a more comfortable living environment by regulating the indoor temperature and reducing drafts. This is especially beneficial in homes with older, inefficient windows.
- Consistent Temperature: Double glazing ensures that your home remains warm in the winter and cool in the summer. The insulating properties of the windows help to maintain a stable indoor temperature, improving overall comfort.
- Reduced Drafts: Older single-glazed windows often allow drafts to enter, which can make a home feel cold and uncomfortable. Double glazed windows reduce the occurrence of drafts, ensuring that your living spaces stay comfortable year-round.
4. Increased Property Value
Investing in double glazed windows can increase the value of your property. Potential buyers are increasingly looking for energy-efficient homes with modern features, and double glazing is a highly desirable upgrade.
- Appealing to Buyers: Homes with double glazing are seen as more energy-efficient and comfortable, which makes them more attractive to potential buyers.
- Increased Market Value: Installing double glazing can increase the value of your home by up to 10%. This makes it a worthwhile investment, particularly if you plan to sell your home in the future.
5. Environmental Benefits
Double glazed windows are also beneficial for the environment, as they help to reduce energy consumption and lower greenhouse gas emissions.
- Energy Conservation: By improving the insulation of your home, double glazing reduces the amount of energy required to maintain a comfortable temperature. This helps to conserve energy and reduce your carbon footprint.
- Reduction of Greenhouse Gases: With less energy needed for heating and cooling, double glazing reduces the reliance on fossil fuels, which helps to lower greenhouse gas emissions and contribute to a more sustainable environment.
