As the pursuit of sustainability gains momentum, New Zealanders are increasingly turning their attention to improving the energy efficiency of their homes. Retrofit double glazing is an effective solution to enhance thermal insulation and reduce energy consumption.

This innovative technique offers immense benefits, enabling homeowners to create comfortable living environments.

Windows play an important role in maintaining the energy efficiency of your home, but they can also create problems by allowing heat to escape or enter. This can result in higher electricity bills which aren't ideal with the rising cost of inflation. Heat loss through the windows in a house can be substantial, though it varies depending on the house's design and insulation levels. Our Low E double glazing range is designed to decrease heat loss through the glass by approximately 78%. That's why retrofit double glazing has become increasingly popular in New Zealand as there are many benefits.

But what exactly does glazing do? How does it work and most importantly, how much does it cost? These are the big questions you might ask when considering double glazing for your home. So, we're here to answer them. This blog deep dives into all the above questions so you can make a better, informed decision.

Final thoughts on how retrofit double glazing works

The retrofit double glazing system works to improve the thermal insulation of a home.

Like traditional double glazing, it creates a thermal barrier between the two panes of glass. The space between these two panes is usually filled with air or an inert gas, which acts as a thermal insulator and helps to regulate the temperature inside the building. This results in;

  • Improved energy efficiency

  • Reduced noise levels, and

  • improved security.

Retrofit double glazing can be an attractive option for those who want to improve the energy efficiency of existing windows without the cost and disruption of full window replacement.
