The revised guide, now spanning 166 pages, features a refined structure that reflects APL’s focus on delivering a fully integrated window system approach. Notably, it now incorporates extensive technical coverage of glass products from sister company Architectural Glass Products (AGP), supporting a seamless, unified approach from frame to IGU selection.

Central to this update is the ‘complete window system’ methodology: APL’s broad suite of aluminium joinery is now offered alongside AGP’s double-glazed Low-E glass, Solux-E and Solux Ultra. This unified approach streamlines the process for specifiers, ensuring that the optimal pairing of thermally-efficient frames and high-performance glass is both code-compliant and simple to document. Both APL and AGP products are backed by rigorous quality assurance, with AGP insulated glass units supported by an industry-leading 12-year warranty.

Another key theme is APL’s long-standing commitment to local design and manufacturing, specifically for New Zealand conditions. In an environment where imported window products are increasingly present, APL stand strong with robust, traceable supply chains and a nation-wide network approaching 80 manufacturers. This dedication offers specifiers enhanced surety around performance, compliance, and post-installation support.

Further, the updated Specifier Guide provides easy comparative charts across the entire ThermalHeart+ range, highlighting APL’s most widely specified windows and doors. The format gives prominence to thermal metrics and direct reference to a new H1 Table which simplifies R-Value and Ug-Value calculations, facilitating the clear, compliant selection of systems under the latest NZBC Clause H1 updates.

Reflecting APL’s ongoing drive toward sustainability, the guide details expanded initiatives around waste minimisation, packaging recycling, efficient energy use, and verified environmental certifications, underscoring APL’s evolving role as a leader in sustainable building methodologies.

“We believe it’s critical to continually improve our processes and reduce our impact,” the guide notes, “by rethinking what we make, setting targets, and sharing our learnings so that we can help raise industry expectations.”

The new APL Window Solutions Specifier Guide is accessible online. Those seeking detailed technical drawings and specification clauses will find supporting Masterspec documents for both APL and AGP, alongside the Specifier Guide on the APL website.
