What is Retrofit Double Glazing?

with Viridian Glass

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.

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

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, LightBirdge and PerformaTech.

What They’re Saying

Client Testimonials

Wonderful and professional

The crew from Rocket 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

When looking to retrofit double glazing in our house we had quotes from a number of companies. Rocket 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
