Winterglaze Retrofit Double Glazing

For a warmer, drier home in winter. For a cooler, comfortable home in summer.

Winterglaze Double Glazing is designed to reduce heat loss through inefficient single pane windows, which up till now, have been the traditional windows installed in NZ homes.  A single pane of glass quickly conducts precious warmth from inside your home, to the outside environment, which is a waste of energy and money.

The Winter Effect


The Summer Effect



How does Winterglaze Retrofit Double Glazing Work?

Retrofit double glazing units fit into a home's current windows, providing a double 'layer' of glass with a pocket of air (or special gas) sealed in between.  It is this separation between the panes that provides the insulation for the window, for warmth in winter and cool in summer.

Why choose Winterglaze for your Retrofit Double Glazing?

The Winterglaze system is only available through authorised Winterglaze dealers, who have the knowledge and expertise to advise and install the correct Retrofit configuration for your home.  Winterglaze Retrofit units are manufactured from high quality components, including the NZ manufactured Insulated Glass Units, which are vital to the quality of insulation offered. With a 5 year warranty and the backing of the nationwide HomePlus group, you can feel reassured that your double glazing needs will be expertly taken care of.
