TQ168 Use of sliding door- Net openable area v4.1 August 2022 EHC
Approved Ruling:
NZGBC clarifies the explicit exclusion of glass sliding doors in the 5% of openable window area in both EHC-1 and EHC-3 due to security, sound and weather concerns. Any window that makes up the 5% openable window area is required to be securable when open. Please note: Projects registered after the publish date of this TC are required to comply. Additional Comments: While it may be possible to secure a glass sliding door while slightly open, , NZGBC contends this is not a good design solution for either cooling or ventilation due to security, noise and safety concerns.
