Brilliant job from start to finish. Easy quoting process and staff helpful. On the day the team arrived promptly, and introduced themselves. Valentin and Jasmin were very professional, polite, and eager to make the installation experience positive. They are a great team! Work completed in a timely manner, windows look wonderful, and they cleaned up before they left. Communication through the day as the job progressed was wonderful. Thanks so much.

Good news: You can replace your windows with double glazing yourself if you're into DIY renovations. We've created a detailed guide to help you!

Why choose retrofit & Double Glazed over replacement?

Choosing retrofit double-glazed windows over replacements offers a blend of comfort, efficiency, and style, particularly in Melbourne's dynamic climate. These windows outperform single-glazed units by significantly reducing heat loss in winter and heat gain in summer, thanks to their superior insulation capabilities—up to 73% improvement. They also reduce external noise by 70%, enhancing your home's tranquillity.

  • Up to 73% Improved Insulation: Our innovative retrofit double-glazed windows boost your home's insulation, keeping you warm in winter and cool in summer without compromising on style or structural integrity.
  • Noise Reduction by 70%: Say goodbye to sleepless nights. Our double-glazed windows significantly reduce external noise, creating a peaceful haven in the heart of Melbourne.

Our Argon-filled units, optionally coated with Low/E, offer unmatched thermal efficiency compared to standard IGUs, all while preserving your existing window frames. This eco-friendly approach retains the architectural integrity of your Melbourne home and is cost-effective, delivering the benefits of double glazing at a fraction of the cost of full replacements. Retrofitting is the smart choice for those looking to improve their home's comfort and security without sacrificing its character or incurring unnecessary expenses.

  • Enhanced Security and Safety: With options for Safety Glass, our installations provide an extra layer of security, offering you peace of mind.
  • Eco-Friendly Solution: Our retrofit installations are a step towards a greener, more sustainable Melbourne by preserving your existing window frames and utilising materials made from 100% recycled components.

Reduced Energy Usage Up To 60%

Do the right thing for the planet and your wallet. Use less energy to heat your home in winter and cool it in summer, especially in Melbourne where temperatures vary from season to season.

Silenced Noise Up To 50%

Double glazing is effective at reducing unwanted noise, such as loud traffic, noisy neighbors, or irritating barking dogs. Our Hush Glass laminate is an industry leader in reducing noise, turning the volume down by over 30% compared to standard double glazing.

Reduced Condensation

Internal condensation creates humidity in your home, leading to discomfort and potentially unsafe mold and mildew growth. Double glazing reduces condensation by providing insulation.

icon 05

Increased Security

Double glazing is much more resistant to breaking than standard glass. Our range includes toughened and thicker options, as well as laminated choices.

We are able to retrofit almost all types of timber windows, including Double Hung, Awning, Casement, Fixed, Clerestory, Doors, and Sliding Windows. If you're unsure, please feel free to send us a photo of your window, and we'll be happy to check it out.

The installation of double glazing can help you save on energy costs, increase comfort, and improve the soundproofing of your property. It also enhances the appearance and value of your property. Retrofitting double glazing is significantly more cost-effective than replacing the entire window frame with a new uPVC, Timber, or Thermally broken aluminum frame, while maintaining similar performance. Additionally, it is a more sustainable option, as it reduces waste by utilising the existing frame.

You don't need to replace your current frames during the retrofit process. Our team will fit the new glass pane to your existing window frame.

Double glazing retrofit is a wise long-term investment that can save you money on energy costs, increase the comfort and value of your property, and improve its sound insulation for many years to come.

Yes, double glazing retrofit is an eco-friendly solution as it helps reduce energy consumption, thus lowering your carbon footprint. Retaining your existing window frames reduces waste compared to discarding frames like some other solutions.
