Energy efficient windows mean reducing the amount of time heating or cooling appliances are needed to keep your home/workplace comfortable. Our double glazed windows and doors are a form of energy efficient glass because they work as insulators to keep an area at an enjoyable temperature all year round. 

Double glazing refers to a sealed glass unit comprising 2 sheets of glass with an air gap between the glass panes. This gap creates the insulation between the inside and outside of the window. 


The two main market options for Australian homes are single and double glazed windows. 

The names are self-explanatory. Single glazed windows are made using one pane of glass; this means the only thing separating the temperatures between inside and outside is one non-insulating pane of glass. A single glazed window has little benefit when it comes to retaining or repelling heat. 

Our uPVC double glazed windows are more than doubly as effective as single glazing. Our product has a U-value (thermal transmittance) of 1.8 when the value of single glazed glass is 5-7. U-value is the rate in which heat transfers through a structure. This means the amount of heat in your home is massively reduced in Summer and increased in Winter when using our product

Double glazed windows are the perfect middle ground between efficiency and cost. Below are the pros and cons of this style of window.

The benefits of double glazed windows far outweigh the cons. The most notable advantage is the superior thermal efficiency. Our product makes it easier and cheaper for you to maintain the temperature within your building. Other benefits include

  • More energy efficient and subsequently reduced electricity cost
  • Noise reduction 
  • Durability 
  • Increased home value
  • Less condensation
  • Higher home security


Some consider the initial expense of double glazed windows as the main disadvantage. However, in the long run, they will likely save you money by cutting costs in other areas such as energy bills. 

Another thing to consider is once the seal is broken between two glass panels the insulative properties cannot be repaired. A break in the window means the whole unit will need to be replaced to re-seal the vacuum between panels. Still, the durability of double glazing makes this a rare occurrence.
