YOUR RETROFIT EXPERT

What is Retrofit Double Glazing?

Retrofit Double Glazing is the process of removing a single pane of glass and replacing it with thermally efficient Low-E double glazing. Low-E double glazing has an invisible metallic coating on the inside of the glass that reflects heat inside your home, keeping you warm all year.

For over 130 years Viridian Glass has been at the forefront of glass technology in New Zealand. The only glass our team uses is Low-E Glass by Viridian.

As customers of Viridian Glass New Zealand, our team has three different types of Low-E Glass that we can supply your home with: EnergySaver, Lightbridge and PerformaTech.

The Retrofit double glazing Process.

Retrofit double glazing is the process of removing the existing single pane of glass in your windows and doors and replacing it with an insulated glass unit that also has a high-quality Low-E glass, which ensures your home is light, warm and comfortable all-year-round.

Are there different Glass Types?

As a home owner, you have many different options for choosing the right type of glass for your home. Our most popular option by far is LightBridge, a clear double-glazed unit that has Low-E glass, an invisible metallic coating that keeps warm air inside your home. Use our FREE online glass calculator to help you find the right glass for your windows.

How long will it take to Retrofit?

We will be able to Retrofit most homes in New Zealand in just one day. A typical home has 30 panes of glass in total and a team of Retrofit Double Glazing installers are fast and efficient. The most important aspect of a Retrofit installation is the preparation before the installation takes place.

What is the Cost of Retrofitting?

This is a question we get asked a lot! Retrofit double glazing costs can range from $350 per pane to $800. There are many factors that need to be considered by our team. Age of existing joinery, the type of glass required, whether scaffolding is required, and of course, the size of your windows.

Client Testimonials

"Wonderful and professional"

Stephen Jowers-Wilding

The crew from Viridian Retrofit was wonderful and professional. They did a thorough job taking the measurements and installing our new double-glazed windows, which turned out great. My family and I noticed that our corridor is now warmer through winter because of the retrofit double glazing, and it has become a more comfortable living environment. We enjoyed their service so much that we have decided to employ them for more installation in the future.

"Knowledgeable"

Chu Tang

When looking to retrofit double glazing in our house we had quotes from a number of companies. Viridian Retrofit were by far the most knowledgeable concerning the double glazing required for our house. They were also very reasonable when it came to the costing. The team of Piripi and Andrew instilled me with confidence, all the way to the end of the project.
