NZS 3604 Table 8.5 Trimming studs

There is a note in Table 8.5 of NZS 3604:2011 Timber-framed buildings that requires an additional trimming stud to lintels when using brick veneer cladding so that the wall ties have something solid to be fixed to. The extra trimming stud requirement also applies where a trimming stud is less than 90 mm wide. It is not required where there is a trimming stud and a doubling stud that are each 45mm in width and the doubling stud is less than 400mm shorter than the trimming stud.
