ThermalHeart+
Following the H1 Energy Efficiency changes to the Building Code, there have been several shifts in the thermal insulation minimums for doors and windows. We have been working hard alongside our partners at Architectural Profiles Limited (APL) to ensure that all our aluminium products are compliant with the current H1 standards.
ThermalHeart+ is our range of code-meeting, industry-leading, thermally efficient products, designed and made right here in New Zealand for exactly how we live.
What is ThermalHeart+?
The whole window system needs to work together to deliver exceptional thermal efficiency. ThermalHeart+ is our innovative system that marries together the latest developments in thermal technology for windows and doors.
ThermalHeart+ consists of three key components that work together to nearly double the performance of standard windows and doors, delivering kiwis with warmer, drier and healthier homes.
- ThermalHEART® thermally-efficient frames
- The AGP System® glass for warmer, drier and healthier homes
- Centrafix™ installation method to increase thermal performance by over 20%.
ThermalHEART® Frames
ThermalHEART® technology can be applied across our range of aluminium joinery suites to combine stylish windows and doors with the latest in thermal insulation.
What is ThermalHEART®?
Innovative ThermalHEART® window and door technology incorporates a polyamide strip in the core of the aluminum window system. The strip serves as a barrier, effectively separating warm and cold areas to insulate the frame.
Why ThermalHEART®?
Aids in managing the risk of condensation forming
ThermalHEART® can aid in managing the risk of condensation forming, therefore reducing the risk of mould growth.
Separates warm and cold areas
ThermalHEART® minimises heat flow through the frame creating a more stable temperature in your home.
Keeps your home comfortable year-round
ThermalHEART® insulates the window system which helps to keep cool temperatures out in colder months, and decrease solar gain in warmer months, assisting in year-round warmth and comfort.
Thermal performance is almost doubled
ThermalHEART® frames, combined with The AGP System™ glass offers 94.7% improvement of thermal performance compared to standard aluminium windows and doors, creating warmer, drier and healthier homes.
ThermalHEART® ranges
- Residential Series ThermalHEART®
- Metro Series ThermalHEART®
- Metro Series ThermalHEART® with Centrafix™
- APL Architectural Series ThermalHEART®
The three ranges share the same core design principles to allow for for exceptional versatility across the full range of products. All ranges can be used within one project to maintain a clean, modern and consistent look.
The AGP System® Glass
The AGP System® works hard to reduce the amount of heat that passes through the glass while still letting natural light through, improving thermal efficiency of a home.
What is The AGP System®?
The AGP System® is a double-glazed unit which is made using world class components and industry leading technology. The panes of glass are processed using a highly automated, precision process to ensure their high quality.
What makes up The AGP System®?
ATS - Architectural Thermal Spacer®
A warm-edge spacer that bonds the two glass panes of your double-glazed windows and doors and creates an airtight bond to ensure the best gas retention of argon gas used in The AGP System®.
Argon gas
An invisible inert gas which is used as an insulator to create an additional barrier to prevent heat loss in winter and heat gain in summer, improving thermal performance.
Solux-E® or Solux Ultra™
Solux-E® and Solux Ultra™ are low emissivity (Low-E) glass coating options, which is virtually invisible and are applied to the inside surface of the exterior glass pane, protecting it from the elements. Both options improve the level of insulation of the home by reflecting the heat back to the inside, reducing winter heat loss through the glass. The reverse happens during the summer helping to limit overheating.
Due to its superior solar control, Solux Ultra™ is the best choice for homeowners wanting to control overheating and is highly recommended for buildings with higher window-to-wall ratio (WWR).
Bonded to glass and secondary sealant
A continually evolving formulation used to ensure durable bonding between glass panes. This creates an airtight seal for the space between panes, providing additional protection for the primary seal.

Centrafix™ Installation
The Centrafix™ installation method is an alternative solution to the New Zealand Building Code standard installation method and a real game changer in thermal performance.
This new BRANZ Appraised installation method minimises thermal losses that normally occur in a typical insulation through recessing the window or door back inside the building wall. This aligns all insulation elements (wall, window frame, glazing) to prevent cold air from circulating around the window and door frames.
Exclusively available in Metro Series ThermalHEART® windows and doors.
What does Centrafix™ do?
Increases the thermal performance in your home by over 20%
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.
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.
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.
Complies with the New Zealand Building Code
Centrafix™ is a BRANZ Appraised and Codemark Certified alternative solution to NZBC E2/AS1.
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.
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. 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
In E2/AS1 installation (the standard method stipulated in the NZBC), the full face of the frame and glazing panels sits outside the wall and in line with the cladding, fully exposed to the colder external temperatures.
Contrastively, the Centrafix™ installation method has the core of the frame and the glazing panels in line with the wall structure and insulation elements, helping to protect it from external temperatures and prevent the loss of heat through the frame.
