Windows with double glazing are becoming increasingly popular in Australia as homeowners look for ways to improve the energy efficiency of their homes and reduce their carbon footprint. However, before purchasing double glazed windows for the home, there are several important factors to consider first. This blog post explores the key considerations for buying windows with double glazing in Australia, including energy efficiency, cost, and installation.
Energy Efficiency
One of the main benefits of windows with double glazing is their improved energy efficiency. Adding a second pane of glass and an air or gas-filled space between the panes creates a barrier that helps keep heat inside the home during the winter and outside during the summer. This can lead to significant savings on heating and cooling costs.
When choosing windows with double glazing for the home, it’s essential to look for windows with a high energy rating. The Australian government’s energy rating scheme, known as the Nationwide House Energy Rating Scheme (NatHERS), assigns a star rating to windows based on their performance. The higher the rating, the more energy efficient the window is. Aim for windows with a rating of at least 6 stars, as these will provide the best energy savings.
Cost
A double-glazed window can be more expensive than traditional single-paned windows, but their energy savings can offset the initial cost over time. The cost of double glazed windows can vary depending on the size, style, and materials used. It’s essential to get quotes from multiple suppliers to compare prices and ensure that the final one is the best deal.
When comparing quotes, it’s also essential to consider the project’s overall cost, including installation and any additional work that may be required. For example, if the existing windows are in poor condition, customers may need to pay for repairs or replacements before installing windows with double glazing.
Installation
Proper installation is crucial for windows’ energy efficiency and performance with double glazing. It’s essential to use a qualified and experienced installer with experience installing windows with double glazing in Australia.
The installer should also provide a warranty on their work and should be able to provide references from previous customers. This will give customers peace of mind knowing that if any issues arise, they can rectify them.
Considerations For Specific Climates
Those who live in a particularly hot or cold region may need to consider specific features for the double glazing in their windows. For example, Low-E coatings and argon gas-filled cavities in hot climates can help reduce heat gain, while in cold climates, warm edge spacers and krypton gas-filled cavities can help improve insulation. It all depends on the type of climate in the area.
Considerations For Specific Styles
Windows with double glazing come in various styles, including casement, awning, sliding, and double-hung. Each style has unique benefits, so it’s essential to consider which style is best for the home and individual needs.
For example, casement windows are a popular choice for homes in Australia due to their energy efficiency and security. Awning windows are also a good choice for homes in the country as they provide ventilation while keeping out rain and insects.
Conclusion
Double glazed windows can provide significant energy savings and improve the comfort of the home. Make sure to use a qualified and experienced installer and consider the specific climate and style of the home. By taking the time to research and choose the right type for the home, Australians can enjoy the benefits of improved energy efficiency and lower energy costs for many years to come.
