Centrafix™
A game changer in thermal performance
The Centrafix™ installation method is an alternative solution to the New Zealand Building Code standard installation method.
This new BRANZ Appraised and Codemark Certified installation method recesses the window or door back inside the building wall, minimising thermal losses which occur in a typical installation. This aligns all insulation elements – wall, window frame, glazing – and prevents cold air from circulating around the window and door frames.
What does Centrafix™ do?
Centrafix™ is a unique, New Zealand designed installation method that is exclusively available in Metro Series ThermalHEART® windows and doors.
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.
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.
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.
The joinery perimeter sits flush against the exterior, while the body of the
window is recessed, enhancing the contemporary aesthetic of your project.
Centrafix™ is a BRANZ Appraised and Codemark Certified alternative solution
to NZBC E2/AS1.
The Centrafix™ window installation system can be specified with higher
performance glazing, frames and special isulating elements around and within
the window frame to achieve passive house levels of thermal performance.
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. By installing your thermally
efficient windows and doors using the Centrafix™ method, the thermal
performance of a home improves by a further 20%.
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.
Centrafix™ comparison figures are based on complete thermal modelling of an average house lot of products installed in 90mm timber framing. The standard installation benchmark was calculated by modelling the same house lot of comparable products using a typical E2/AS1 cavity construction installation on 90mm timber framing.
