Getting new windows is easy

Windows replacement process madу comfortable and transparent.

Why Melburnians replace their windows?

  • The house is cold in winter and heats up in summer
    Single glazed windows can be responsible for up to 35-40% heat loss during winter and heat gain during summer. Juts think about it! More than a third of your electricity bill comes from poor windows!
  • It's too loud, I can hear everything from the street
    Cheap or old single glazed windows allow a lot of street noise in, including road traffic, loud neighbours, road works etc.
  • The room feels damp, I get a lot of condensation every morning
    Since single glazed windows allow a lot of heat to escape at night so your windows get condensation on the glass. It creates unhealthy environment where mould starts to grow.
  • The glass is so thin, I don't feel safe for my kids​
    The old windows still have 3mm glass in them, which is very fragile and can easily crack under pressure causing serious injuries. It is illegal to install 3mm glass any more.
  • My windows are not working properly, they are rusty / started to rot
    Aluminium windows often start to rust while timber windows rot with time. They require constant maintenance, otherwise they no longer function properly. Furthermore, cheap windows are not designed to last long so unfortunately people get what they paid for.​

What windows to choose and why?

When you come to a decision to replace your windows, the best solution on the market is uPVC Double Glazed windows. They address all of the above concerns making them the go to choice. See why the whole Europe, Canada and America switched to uPVC Double Glazed windows over three decades ago.


The uPVC material is the top choice around the world when it comes to windows. Try sitting on a metal chair in a café on a cold Saturday morning as opposed to a plastic chair to feel the difference.

Our windows are double glazed by default with Low-E glass and argon gas as standard, which offer exceptional thermal insulating qualities.

The multiple locking hardware ensures that you don't get that "wabbly" feeling associated with the cheap wind out windows. Our windows seal all around the sash tight and secure.


All our products comply with Australian Standard (AS 2047) and are safe to use. We can offer either toughened or laminated glass in the areas which require extra safety.

The uPVC material does not discolour nor emit any toxic material when heated. Neither does it support combustion. It is UV stabilized and is designed for Australian climate.


Our windows are made from a 70mm multiple chambered uPVC profile designed to keep the noise out. We offer various glass configurations ranging from classic double glazing to triple glazed and acoustically laminated glass units.

Proper installation is a big factor to the noise reduction qualities of your new windows. Your new frames get foamed all around followed by professional caulking, which eliminates any pathways for the noise to get through.


Condensation on the glass is simply a sign of poor insulation qualities of your old window. A lot of heat escapes through thin glass in winter, causing moisture to accumulate on the glass. The moisture also gets trapped in the air causing molds and various diseases.

Our classic product offering comes in double glazed configuration with Low-E glass and Argon gas as standard. The u-value for the classic offer starts at 1.6, which guarantees your windows to be condensation free. Please note that the argon gas is sealed within each IGU (insulated glass unit) and is non-toxic in case a glass gets broken.


uPVC doesn't rust, nor rot, and lasts virtually a lifetime. Clever design coupled with top quality German corrosion proof hardware by SIEGENIA will guarantee your windows will last years to come.

Windows Republic offers 10 year guarantee as standard for your peace of mind.
