Garage doors and other large access doors
|Publication Date:||6 February 2013|
This Standard specifies requirements for the design, construction, and installation of garage doors and other large access doors in external walls of buildings.
This Standard covers domestic doors for openings up to three metres in height and general purpose doors for openings of any height.
This Standard includes provisions to evaluate actions transferred from the doors to the supporting structure or building.
The Standard includes the following:
(a) Door classification.
(b) Ultimate wind pressure rating.
Where a building design includes a requirement for a wind-borne debris impact rating, Appendix B sets out a procedure for wind debris impact rating for doors.
1 For Class 2 to 9 buildings, as defined in the NCC, ultimate wind pressure ratings for doors are compatible with pressures from AS/NZS 1170.2.
2 For Class 1 and Class 10 buildings, as defined in the NCC, ultimate wind pressure ratings for doors can be compatible with either AS 4055 or AS/NZS 1170.2.
