- May be used in importance level 1 and 2 buildings up to a Wind Zone of ‘Very High’ and in all corrosion zones, as defined in NZS3604:2011. Where a Wind Zone greater than ‘Very High’, DriStud Wall Wrap may still be suitable but a registered engineer should be consulted and the use falls outside the scope of this certificate.
- Where it is to be installed in an existing building, the designer and installer must assure themselves that the existing building is suitable for the intended building work and that the provisions of s112 of the NZ Building Act 2004 will be met.
- DriStud Wall Wrap is suitable for use with steel or timber framing.
- May be installed in conjunction with face fixed and ventilated cavity systems as established via E2/AS1 except that where a non-absorbent cladding system is specified, an 18mm minimum drained cavity must always be used.
- Where a flashing tape, other than DriStud Cool Window Flashing Tape or DriStud Bozz Window Flashing Tape is used, the installer and designer must assure themselves that the tape is suitable for the intended building work.

OVERLAPS / SUPPORT
DriStud Wall Wrap must be installed horizontally with printed side facing out. Any joins must be overlapped by a minimum of 150mm. Where horizontal laps are required the upper sheet must overlap the bottom one to allow for moisture run off.
