Advantages of Custom/UPVC Double Glazed windows ​in Melbourne​

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:

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

How does it work?

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.

As environmental awareness increases, so does the demand for energy-efficient solutions. Single-glazed windows are quickly becoming a thing of the past as they do not provide enough insulation to keep your home warm and reduce energy bills.

The old style single glazed windows are made with a single sheet of glass that is not very effective at keeping out draughts or heat loss. This leads to increased energy consumption and higher costs on bills. Furthermore, intruders can easily break into single-glazed windows, leading to further problems like burglary and property damage.

It is common practice to upgrade from single-glazed windows to double or triple glazing for improved insulation and security benefits. The extra layer of glass reduces heat loss considerably and provides more soundproofing from outside noise pollution.

Besides inferior thermal performance for your home, single glazed windows provide little protection against heat, cold, noise, and condensation. They are also made of a dangerous float glass which causes serious injuries when cracked. Windows Republic uses toughened safety glass which will never harm your family members even if smashed.

When it comes to windows replacement options in Melbourne, UPVC double glazed windows are an excellent choice. Double glazing effectively reduces heat loss, making your home more energy efficient and comfortable all year round. Not only do double-glazed windows provide improved thermal insulation, but they also help dampen sound from outside your home.

Furthermore, double glazing provides a longer lifespan for your windows due to its strength and durability compared to other traditional window material types, such as single-pane glass or wooden window frames.

By selecting double glazed windows in Melbourne, you can expect a decrease in condensation, mold growth, and outdoor noise levels.

Plus, the bonus of having more peace of mind is knowing that you have made an investment that will last for many years!

If you’re a homeowner, trying to decide between repairing and replacing your windows can be difficult. Double glazed windows are an increasingly popular choice due to their insulation benefits; however, they aren’t immune to damage over time. Knowing when it’s time for repairs or a complete replacement can be tricky – but some telltale signs will help you make the right decision. First and foremost, if your double glazing has started to let in draughts or has become difficult to open or close, you may need repairs. This is often caused by worn-out gaskets, broken seals, and other issues which can easily be fixed with maintenance work.
