Compare APL Joinery Suites.

To find the most suitable aluminium joinery profile/s, compare the APL Metro Series with the Residential Series for a more cost-effective, mainstream option, or with the APL Architectural Series for enhanced performance. Each range provides distinct benefits, ensuring you choose the APL joinery profile/s that perfectly suits your project's needs.

All three series—APL Architectural Series, Metro Series, and Residential Series—are designed with the same fundamental principles, providing exceptional flexibility. This allows for easy integration of these aluminium joinery ranges into a single project while ensuring a unified aesthetic (excluding Metro Series ThermalHEART® with Centrafix™).

Partnering with Windowmakers means working with professionals who will help you choose an aluminium joinery suite/s tailored to your project's unique needs. We collaborate with you to fully understand your vision and recommend the ideal aluminium door and window frame solution.

ThermalHEART® Thermally Broken Frames.

Every window and door product in the Metro Series is equipped with ThermalHEART® thermal break aluminium technology, which incorporates a polyamide strip within the aluminium window frame. This enhances energy efficiency to meet the latest NZBC H1 standards while creating a warmer, drier, and healthier home.

Glass Options.

Each of our aluminium doors and windows incorporates The AGP System®, a high-performing Low-E argon filled double glazing that minimises heat transfer while allowing natural light to flow through, improving thermal efficiency. Paired with ThermalHEART® thermally broken aluminium frames, The AGP System® nearly doubles the thermal performance of standard windows and doors.

Our aluminium doors and windows come with Solux-E Low-E coating. However, for superior solar control, we recommend upgrading to Solux Ultra™ Low-E, specifically for projects where managing overheating is a priority or buildings with a higher window-to-wall ratio (WWR).

Centrafix™ Installation System.

Centrafix™ Installation System is exclusively available for our Metro Series ThermalHEART®. This BRANZ appraised and Codemark Certified alternative to the NZBC standard installation method recesses aluminium doors and windows into the building wall. By aligning the insulation elements—wall, aluminium window frame, and glazing—it prevents cold air from circulating around the frames, improving thermal efficiency and reducing heat loss typically associated with standard installations of aluminium joinery. When applied to your Metro Series ThermalHEART® windows and doors, it can enhance thermal performance by a further 20%.
