Loving Glass Series: Double glazing - the gold standard in glass selection

People talk about the huge benefits of double glazing, we want to take a deep dive into the technology which makes up a double glazed unit before it is built into your window frames.

What is a double glazed unit? 

A double glazed unit is two pieces of glass sealed with a spacer bar. The spacer bar is the strip you see in between the two pieces of glass. Before the unit is sealed we fill it with argon glass and depending on the type of product we may also include a Low E coated glass on one side of the unit, which increases the energy performance. The argon gas, the spacer bar and (in some products) the Low E coating creates perfect conditions for added insulation.

How is double glazing made?  

Viridian double glazed units are made here in Australia using both local and imported components.

The Viridian Glass business employs just over 500 Australians - who work across the country to process and supply glass. 

We locally process the components through our factories in both Sydney and Melbourne and distribute to our window trade customers across the country.

Double glazing is made by running both pieces of glass through a combination of automated and manual processes to ensure quality and efficiency.  Our staff then check units for quality before they are safely loaded on to our trucks to either be sent to our window customers' premises or straight to a building site. We supply the product according to our customer requirements for the order. 

Viridian Glass office support staff in Sydney did a double glazing workshop last year to follow the process of how a double glazed unit is made, here are some snapshots. We have a hard working and focused team who are dedicated to this process!

How is double glazing installed into my home? 

Your builder or installer will order the glass from us on your behalf and manufacture the unit into your chosen frame. This is why it's important you work with your window installer to ensure you choose the framing which accommodates the double glazing your choose. This applies if renovating or building.
