The EZpanel Cavity System has been appraised (BRANZ Appraisal 649) as an external wall cladding system for buildings within the following scope:

• the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
• with a risk score of 0-20, calculated in accordance with NZBC Acceptable Solution E2/ AS1, Table 2; and,
• situated in NZS 3604 Wind Zones up to, and including Extra High

The EZpanel Cavity System has also been appraised for weathertightness and structural wind loading when used as an external wall cladding system for buildings within the following scope:

• the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
• constructed with timber and steel framing subject to specific engineering design; and,
• situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 2.5 kPa.

The EZpanel Cavity System is finished with either a cement-based option or an acrylic-based option.

• The cement-based option consists of a base coat of MLC plaster followed by either a cementbased finishing plaster or an acrylic-based finishing plaster
• The acrylic-based option consists of a flanking coat of MLC plaster followed by a mesh coat of Powaflex acrylic plaster and an acrylicbased finishing plaster.

Both base coat options are finished with an acrylic exterior paint system.

• The EZpanel Cavity System must only be installed on vertical surfaces (except for tops of parapets, sills and balustrades, which must have a minimum 10º slope and be waterproofed in accordance with the Technical Literature)
• The system is appraised for use with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills. (The Appraisal of the EZpanel Cavity System relies on the joinery meeting the requirements of NZS 4211 for the relevant Wind Zone or wind pressure.)
• Installation of components and accessories supplied by Specialized Construction Products Ltd, its certified distributors and approved applicators must be carried out only by Specialized Construction Products Ltd approved applicators

In the opinion of BRANZ, the EZpanel Cavity System if designed, used, installed and maintained in accordance with the statements and conditions of this Appraisal, will meet the following provisions of the NZBC:

• Clause B1 STRUCTURE: Performance B1.3.1, B1.3.2 and B1.3.4. The EZpanel Cavity System meets the requirements for loads arising from self-weight, earthquake, wind, impact and creep [i.e. B1.3.3 (a), (f), (h), (j) and (q)]. See Paragraphs 10.1 - 10.5
• Clause B2 DURABILITY: Performance B2.3.1 (b), 15 years, B2.3.1 (c), 5 years, and B2.3.2. The EZpanel Cavity System meets these requirements. See Paragraphs 11.1 - 11.3
• Clause E2 EXTERNAL MOISTURE: Performance E2.3.2. The EZpanel Cavity System meets this requirement. See Paragraphs 17.1 - 17.5
• Clause F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The EZpanel Cavity System meets this requirement and will not present a health hazard to people

• AAC products have been produced worldwide for more than 80 years

• Specialized’s EZpanel System is guaranteed for 15 years from the date of practical completion
• Very low environmental impact — AAC’s high resource efficiency gives it low environmental impact in all phases of its life cycle, from processing of raw materials to the disposal of AAC waste on site during construction. In the manufacturing process, no pollutants or toxic by-products are produced
• Increases in impact resistance and fire performance
• EZpanels will not rot, pest resistant
• Excellent sound insulation properties
• The exterior positioning of the EZpanels also places their fantastic insulation characteristics as close a possible to where temperatures fluctuates reducing ongoing energy consumption compared to most conventional exterior wall cladding systems.
