Centrafix™ installation vs. E2/AS1 installation

When viewing the installation methods side-by-side, you’ll notice that the full face of the E2/AS1 frame and glazing panels sit outside the wall, in line with the cladding meaning it’s fully exposed to the colder external temperatures. E2/AS1 cavity construction installation is the standard installation method as stipulated in the New Zealand Building Code.

The Centrafix™ installation has the core of the frame and the glazing panels in line with the wall structure and insulation elements, helping to protect it from the external temperatures and preventing the loss of heat through the frame.

All insulation elements are aligned improving thermal efficiency

21.6% increase in thermal performance vs. standard installation2

What does Centrafix™ do?

Centrafix™ is a unique, New Zealand designed installation method that is exclusively available in Metro Series ThermalHEART® windows and doors.

Increases the thermal performance in your home by over 20%2

This innovative installation method aligns all insulation elements – wall, window frame, glazing – which prevents cold air from circulating around the window and door frames, improving the whole window system’s thermal performance.

Complies with the New Zealand building code

Centrafix™ is a BRANZ Appraised alternative solution to NZBC E2/AS1.

Aligns all insulation elements

Recessing the window and door units realigns the insulating elements of the window frame and glazing with the insulation elements of the wall, improving thermal efficiency.

Offers clean, contemporary lines

The joinery perimeter sits flush against the exterior, while the body of the window is recessed, enhancing the contemporary aesthetic of your project.

Recesses into the building wall

Centrafix™ is designed to safely and efficiently recess a window or door unit from the front face of the cladding back into the building wall, minimising the thermal losses that occur in current installation methods.

Completes your thermal window system

Your windows and doors are a complete system with each component (the frames, the Insulated Glazing Unit, the installation) contributing to the overall performance and comfort of your home. For the ultimate in thermal performance, the whole window system needs work together to complete your thermal window system.

Offers a Passive House variant

The Centrafix™ window installation system, can be specified with higher performance glazing, frames and special insulating elements around and within the window frame to achieve passive house levels of thermal performance.
