If your windows need replacing, by choice or necessity, our replacement window solution is a great option for your home.
How does the process work?
Installation is a straightforward process. Using our retroGLAZE® system, we will remove your windows (frames and glass) and replace them with new ThermaL 4.0™ joinery. Coupled with our True-Warm-edge SuperSpacer® and our high performance SuperTherm™ glass, you will have windows that look great, perform exceptionally and are built to last.
On completion, you will be provided with a WEERS certificate showing the performance rating of your new windows. By choosing ThermaL 4.0™ with our highest performing SuperTherm™ double glazing, your windows will qualify for New Zealand’s Energy Star standard. On the WEERS rating system, which scores windows on their thermal performance out of a maximum 6 stars, our ThermaL 4.0™ windows consistently achieve above 5.5 stars.
