When it comes to upgrading windows in your home, there are several factors to consider. One of the most important decisions is between double glazed windows and traditional single glazed windows.
Double glazing windows have become the go-to choice for many homeowners as they provide superior insulation when compared to traditional ones.
This means that your home is better protected from outside temperatures and noise pollution, allowing you to save on energy bills while enjoying greater comfort.
Double glazing also offers increased security due to its thicker glass and more robust locking mechanism.
Double glazing windows can hand painted white to give it a very specific colour. Works best for smaller orders where a specific colour needs to be matched (like for Body Corporates). The paint used was specifically developed for uPVC windows. There are 40,000 colours to choose from.

Double glazed windows and doors are becoming increasingly popular in modern homes and businesses, with many people switching to these energy-efficient alternatives. But what exactly makes double glazed doors eco-friendly?
Double glazed windows involve two panes of glass fitted into a single frame, with a small gap between them.
This creates an insulating barrier that helps to reduce heat loss from buildings while also providing better soundproofing qualities than standard windows.
As more heat is retained inside the building, it reduces energy consumption and lowers bills for those who use double glazed doors.
In addition, this insulation also reduces carbon dioxide emissions from heating systems and can significantly improve air quality in our homes and workplaces.
Then, as the first step, consider better insulation around your house, be it roof/wall/ceiling insulation, single glazed windows, fans and vents, or other causes.
In winter, an average Melbourne home can lose up to 40% of its heating energy through windows and gain twice more in summer or up to 87% (Source: yourhome.gov.au).
To put this in perspective, it is useful to compare U-values of common window types found in Melbourne today. With windows, the lower the U-value the better window insulates against heat.
Typical single glazed aluminium window with 3mm glass has a U-value of 7.4
Typical single glazed timber window with 3mm glass has a U-value of 5.5
Windows Republic uPVC double glazed window with Low-E glass has a U-value of 1.4
Our double glazed are made of energy efficient European type uPVC frames and sashes and double glazed insulated glass units, which consist of two panes of glass, argon gas between the glass panes and Low-E coating. Great for your home if you are trying to save money. Glazing Savings!
Windows Republic double glaze windows will noticeably reduce street noise compared to the conventional single glazed windows. However, for a home facing busy roads, better results can be achieved with Triple Glazed or Acoustic Glass windows.

Double glazing is becoming increasingly popular in homes around the world. It can provide various benefits, from improved energy efficiency to noise reduction. But how exactly do double glazed windows work?
Double-glazing involves two layers of glass with an air gap between them. This air gap acts as an insulator and helps to prevent heat transfer between the inside and outside of your home. In addition, double glazing is designed to reduce sound pollution significantly – up to 70% in some cases – making it perfect for city dwellers who want peace and quiet in their homes.
The air gap in UPVC window double-glazed can be filled with either argon gas or krypton gas, which are natural insulators that help keep the temperature inside stable while blocking out external noises.
Our double glazed windows will noticeably reduce street noise compared to conventional single glazed windows. However, for a home facing busy roads, better results can be achieved with Triple Glazed uPVC or Acoustic Glass windows.
Double glazed windows in Melbourne typically cost between $1800 and $3500 per window depending on size, frame type, and glass specification. Premium uPVC double glazing with acoustic laminated glass or triple glazing (10-15% more) can cost more but delivers superior energy efficiency and noise reduction.
Windows Republic manufactures locally in Melbourne, allowing competitive pricing and faster installation compared to imported systems.
Yes. Double glazed windows are highly effective in Melbourne’s climate, improving thermal insulation in both hot summers and cold winters. They reduce energy bills, minimise condensation, and significantly improve indoor comfort.
Homes near busy roads, tram lines, or flight paths also benefit from substantial noise reduction.
Yes. Double glazed windows can reduce outside noise by 30–50% depending on glass thickness, air gap, and sealing quality. Acoustic laminated glass and wider cavities can achieve even higher reductions, making them ideal for homes near traffic, trains, or commercial areas.
For maximum noise control, specialised acoustic systems like laminated glass configurations are recommended.
High-quality double glazed windows can last 20–35 years or more when properly manufactured and installed. uPVC frames are particularly durable because they do not corrode, rot, or warp in Australia’s harsh sun and coastal conditions.
Regular maintenance of seals and hardware helps maximise lifespan.
uPVC frames generally outperform standard aluminium in thermal insulation and noise reduction because uPVC does not conduct heat. This results in better energy efficiency and lower condensation risk.
Thermally broken aluminium systems can perform well but are usually more expensive than high-performance uPVC double glazing.
Yes. Double glazing can increase property value by improving energy efficiency, comfort, and acoustic performance — all features increasingly valued by Melbourne buyers. Energy-efficient homes often attract stronger resale interest and can achieve higher sale prices.
Yes. Double glazed windows can reduce traffic noise by 30–50%, with greater reductions possible using acoustic laminated glass and wider air gaps. Proper sealing and installation are critical for optimal performance.
Acoustic double glazing with laminated glass and large air cavities provides the best noise reduction. uPVC frames also help because they seal tightly and do not transmit vibration like some metal frames.
High-performance acoustic double glazing can significantly reduce train and aircraft noise, particularly when using thick laminated glass and specialised acoustic designs.
Triple glazing can improve noise reduction in some cases, but acoustic laminated double glazing with asymmetric glass thickness often performs better for traffic noise.
