The ENCLOSURE Blueprint

ENCLOSURE™ A&B Anchoring System

The ENCLOSURE™ A&B Anchoring System is an engineered aluminium anchoring solution designed for the installation of ALPOLIC™ fr (ACP) façade panels. The system comprises two extruded aluminium components. ENCLOSURE™ A is fixed to the structural framing over packers, while ENCLOSURE™ B is secured to the primary extrusion, creating a robust support framework for the façade. Formed ALPOLIC™ fr panels are then riveted directly to the extrusions.

Designed for strength, durability, and installation efficiency, the A&B Anchoring System provides reliable support for a wide range of façade applications and can be used in projects with design wind pressures of up to 3.6kPa (ULS). For added confidence in specification and compliance, ALPOLIC™ fr installed on the ENCLOSURE™ A&B Anchoring System is covered under BRANZ Appraisal No. 528 (2024).

Key Features

01

Engineered for the installation of ALPOLIC™/fr

The ENCLOSURE™ A&B Anchoring System has been specifically engineered for the installation of formed ALPOLIC™/fr aluminium composite façade panels, providing a coordinated and compliant façade solution.

02

Integrated Cavity Design

The system creates a minimum 40 mm cavity between the structure and the outer face of the panel. High-impact plastic packers are used to form the cavity, eliminating the need for traditional cavity battens and simplifying wall assembly construction.

03

Supports High Wind Load Applications

ALPOLIC™/fr installed on the ENCLOSURE™ A&B Anchoring System may be used for applications with design wind pressures of up to 3.6 kPa (ULS), making it suitable for a wide range of commercial and architectural projects.

04

Part of a Complete Façade Assembly

The A&B Anchoring System forms the structural interface between the building structure and ALPOLIC™/fr façade panels, supporting the long-term performance of the complete cladding system.

Application

Scope of Use

The ENCLOSURE™ A&B Anchoring System is designed for the installation of ALPOLIC™/fr aluminium composite façade panels as part of a complete external wall cladding system. The system is suitable for:

  • Commercial, institutional, and multi-residential façade applications
  • Timber-framed construction designed in accordance with NZS 3604 or specific engineered design requirements
  • Projects with design wind pressures up to 3.6 kPa (ULS)
  • Wall assemblies incorporating a drained cavity and rigid air barrier where required by project-specific design and wind loading requirements
  • New-build and re-clad façade applications

ALPOLIC™/fr installed on the ENCLOSURE™ A&B Anchoring System is covered by BRANZ Appraisal No. 528 (2024).

Compliance

Compliance with the New Zealand Building Code

ENCLOSURE™ A&B Anchoring System contributes to compliance with the following NZBC clauses when used as part of a compliant wall assembly:

BRANZ Appraised

ALPOLIC™/fr installed on the ENCLOSURE™ A&B Anchoring System is covered by BRANZ Appraisal No. 528 (2024), providing a recognised pathway for specification and compliance.

Why specify

Why Architects Specify ENCLOSURE™ A&B Anchoring System

Architects and designers specify the ENCLOSURE™ A&B Anchoring System because it provides a tested and appraised anchoring solution specifically developed for ALPOLIC™/fr façade systems.

  • Purpose-designed for ALPOLIC™/fr aluminium composite panels
  • Robust two-part extruded aluminium anchoring system
  • Suitable for design wind pressures up to 3.6 kPa (ULS)
  • Integrated cavity design without the need for traditional cavity battens
  • Durable aluminium and stainless steel construction
  • Supported by BRANZ Appraisal No. 528 (2024)

The ENCLOSURE™ A&B Anchoring System provides a reliable connection between the building structure and the ALPOLIC™/fr façade, forming part of a compliant façade assembly designed for New Zealand conditions.
