Replacement Windows & Doors

What is ThermaL 4.0 Joinery?
ThermaL 4.0™ is the next generation of thermally enhanced aluminium joinery developed in partnership with Fairview Systems, NZ leaders in window and door solutions.

ThermaL 4.0™ joinery has a thermal break positioned within the joinery which slows down the movement of heat/cold from the inside and outside surfaces of the window frame. This thermal break reduces the heat transfer through the aluminium joinery, meaning the ThermaL 4.0™ frame keeps your home warmer in winter, cooler in summer and drier all year around.

When combined with our high-performance SuperTherm™ Low-E double glazing you will have a warmer, drier home in winter and a cooler home on those hot summer days.

What is the difference between Full Replacement and Insert Windows?
We have two Replacement Window and Door solutions:

Insert Windows - allow you to retain some of the character of your existing timber or aluminium frames as the reveals, or the timber surrounds around the window, are retained. 

Full Replacement Windows and Doors - removes all components of the existing window or door including the reveals and sills, giving you a completely new look to your windows and doors.

Don't suffer any longer with poor-performing, flimsy windows and doors. Get your customised plan for home comfort with retroGLAZE® Replacement Windows and Doors.

Should I retrofit or replace my existing windows?
Deciding whether to retrofit or replace your windows and doors can feel confusing, or even overwhelming.
Retrofit double glazing uses your existing timber or aluminium frames, replacing the old single glazing with new double glazing. In contrast, Replacement Windows and Doors involve removing both the existing glass and frames of your aluminium or timber windows and doors, and replacing them with thermally enhanced joinery.  Read more here…

Does double glazing eliminate condensation?
Sick of having to dry off your window frames through winter? Do you have beautiful timber joinery, but the constant puddles are starting to cause the timber to deteriorate and rot?
With double glazing, the thermal insulation between the outside and inside is greatly improved resulting in a significant reduction in condensation, creating a warmer, drier, healthier home. Read more here…

What is the WEERS rating?
Changes to Clause H1 in the NZ Building Code require homes to achieve a minimum energy performance. WEERS, or the Window Energy Efficiency Rating System, enables you to accurately assess the energy efficiency of the windows or glazed doors you choose. Read more here...
