What is Retrofit Double Glazing?
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.
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 effecient. The most aspect of a Retrofit installation is the preperation before the installation takes place.
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 metalic coating that keeps warm air inside your home.
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 scafolding is required, and of course, the size of your windows.
Our Process for Retrofit
New double glazed units are inserted into your window frames with a new external bead for your fixed windows and your opening windows will be replaced with new sashes, stays and handles.
