Why Retrofit Double Glazing?

Now you can enjoy the comfort and lower heating bills that come with double-glazing. RetroFit double glazed windows are individually crafted to fit your existing joinery, so you will keep the look of your home but upgrade its comfort. You will save money on heating, reduce condensation and cut down external noise.

By choosing the Retrofit service, you gain the confidence of dealing with New Zealand's largest glass and glazing company Metro Performance Glass.

At Retrofit, we use the latest Low E glass technology in our double glazed window units. Low E stands for ‘low emissivity’, which means the glass reflects more heat and solar rays than plain glass does. Therefore, when you are heating your home during winter, less of the warmth will be lost through the glass. Conversely, when the sun is beating down in summer, less heat and solar radiation will enter the building.
