Description

IBuilt CoreClad panels are manufactured from both Hoop Pine and Klinkii Pine, which have been grown from sustainably managed plantation forests.

Individual veneers are ACQ treated to meet hazard class H3.2 and then manufactured into plywood sheets by bonding the treated veneers with a Type A structural marine bond. The plywood sheets are machined, band sawn, grooved (if required) and ship-lapped to form the finished cladding panel.

The manufacture of IBuilt CoreClad is third party certified by EWPAA to meet AS/NZS 2269:2012-Plywood Structural Standard.

IBuilt CoreClad panels are supplied Grade S-D, F14 in the following dimensions:

Sheet thickness: 12mm
Sheet length: 2440, 2745, 3050mm
Sheet width: 1200mm (cover), 1220 (overall)
Sheets available: Textured Grooved 150 and Textured

Scope of Use

CoreClad panels are for use as external cladding

Location:

In wind zones up to extra high, as defined in NZS 3604:2011 or to a design wind pressure (ULS) of 2.5kPa
In all corrosion zones as defined in NZS 3604:2011

Building:

In conjunction with a primary structure that complies with the NZ Building Code, or where the designer and/or installer has established that the existing structure is suitable for the intended building work
CoreClad may be direct fixed or installed over a drained, ventilated cavity

Limitations on Use

Location:

Where adverse microclimatic conditions apply, as set out in paragraph 4.2.4, NZS 3604:2011, contact IBUILT for technical advice
Must be located further than 1 m from a relevant boundary

Building:

The building is to fall within the scope of E2/AS1 paragraph 1.1 for building height and floor area
Direct fixed only applies where the elevation has a risk score of 6 or less (refer table 3, E2/AS1)

Statement of Building Code Compliance

If designed, installed and maintained in accordance with all IBUILT requirements, CoreClad will comply with or contribute to compliance with the following performance claims:

B1 Structure: B1.3.1, B1.3.2, B1.3.3 (a, b, f, h, j, m, q), B1.3.4 (a, b, c, d, e)
Alternative Solution AS/NZS 2269:
- Plywood manufactured to AS/NZS 2269 is referenced in E2/AS1 for use as a rigid air barrier and external cladding. This implies that plywood to this standard will have the necessary structural integrity for those uses.

B2 Durability: B2.3.1(b), B2.3.1(b)
Verification Method:
- B2/VM1: cl1.3 Verification through comparison with a similar material
- AS/NZS1604.3, para 1.9 requires same characteristic values for penetration & retention as defined in NZS 3640:2003
- IVS test results show these values are met

E2 External Moisture: E2.3.2, E2.3.5, E2.3.7 (a, b, c)
Acceptable Solution E2/AS1
- Installation to section 9.8
F2 Hazardous Building Materials: F2.3.1
