Our retrofit service
Retrofit double glazing is the process of replacing your home's existing single glazing with new energy efficient double glazed units.
The process is quick and unobtrusive and is not a low quality, clip-on solution. Our double glazing solutions are purpose built for each home, comply with the NZ Building Code, and backed by a 10- year warranty.
We use special ‘low emissivity’ (Low E) technology that lets in light and heat from the sun but also reduces the amount of heat escaping your home. Click here to learn more about what Low E.
We also have solar control glass options that reduce the risk of your home overheating in the hotter summer months.
We have a wide range of frame colour matching options to suit your existing window frames.
The image on the right shows an example of what our double glazed units are made up of. Click here to learn more about double glazing.
