How does this affect my renovation or new build? Frameless glass balustrades previously constructed from toughened glass will now all need to be made from laminated glass. This is a safer but significantly more expensive option. Toughened glass systems will still be accepted by council but only if they are fully framed – top and side – by a steel interconnecting member.
How does this affect my building consent that was issued prior to the 1st June 2016? Building consent applications for glass barriers that were accepted before 1 June 2016 may use the old version of B1/AS1 (Amendment 12) to show compliance with the Building Code.
How does this affect my building consent that was issued on the 1st June 2016 or later? Building consent applications for glass barriers made on 1 June 2016 or later must comply with the new barrier requirements in Amendment 13 of B1/AS1 (i.e. section 22 of NZS 4223.3:2016). If an alternative method is proposed, the application should include appropriate documentation to show compliance with clause B1 Structure.
How does this affect my existing glass barriers? Existing glass barriers are not required to be upgraded to comply with the new requirements, although retrofitting structural glass barriers to comply with NZS 4223:3:2016 may be possible.
