- Appraisal #870; vertical cladding over cavity
The scope of both of these appraisals extends to risk score 20 per NZBC Clause E2/AS1.
Where a direct-fixed cladding solution is required (e.g. in the case of re-cladding a wall on a boundary), Nu-Wall can be specified for installation per the following BRANZ appraisal:
- Appraisal #556; direct-fixed vertical cladding
The scope of the above appraisal also extends to risk score 20 per NZBC Clause E2/AS1.
A fourth BRANZ appraisal (#557) relating to direct-fixed horizontal cladding is being withdrawn by Nu-Wall, effective from 31st July 2015.
