What is Retrofit Double Glazing?

Retrofit double-glazing is the process of replacing your existing single glazing with double glazed units. The process is quick and unobtrusive. The only difference you will notice is a more comfortable temperature all year round.

This is not a low quality, clip-on solution. Our double-glazing solutions are purpose built for each home, and meet the highest construction standards. All materials can be colour matched to suit your existing window frames.

A significant amount of heat is lost through the windows in a house. While this depends on the design and insulation levels of the house. Modern houses with insulation that meets the 2009 building code will lose up to 45% of their internal heat through single glazing. You can reduce the heat loss by up to 33% with classic double-glazing, and less than 28% with the Low E double glazed units that RetroFit installs.

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.

A warmer house in winter comes from using Low E Double Glazing, keeping the heat in and the cold out. And because there is less need for heating systems, you'll be reducing energy consumption, which saves on your power bills and helps the environment.

RetroFit Double Glazing keeps your house warmer

 Reduced condensation

Condensation is that “crying look” that single glazed windows get. This is a serious problem, it causes mould and mildew, and in some cases, it will also rot timber window frames and damage your family's health.

Cooler in summer

A cooler house in summer reduces solar heat gain that can overheat your house, while also insulating your house from the temperature outside.

 Reduced Noise

Reduced Noise for a calmer, quieter home. High performance double-glazing can reduce outside noise, making it a great investment if you live by a busy road or beneath a flight path.  Ask us about our sound solutions.

 Safety 

A Safer and more secure home, as it is more difficult for intruders to break in through double glazed windows, particularly if you include laminated or toughened glass.  The use of safety glass will also upgrade your existing single glazed windows to current Human impact building code requirements.

 Potential to Improve Resale Value 

Better resale value of your home. Now an older home can be just as desirable to the purchaser who wants to ensure that the house they buy is efficiently insulated. With retrofit double-glazing, any home can get these benefits!
