    In NSW, Under regulations, “Double Glazing” is defined a “Minor renovation”

    See: https://legislation.nsw.gov.au/view/whole/html/inforce/current/sl-2016-0501#sec.28

    As such, it can be approved by a simply majority as a general meeting (or by the committee if that power has been delegated it it) and no by-law would needed.

    See: https://legislation.nsw.gov.au/view/whole/html/inforce/current/act-2015-050#sec.110 for Minor Renovatns, and in particular see 110(8) which says section 108 does not apply. Section 108 covers many things, and includes the section that allows responsibility for maintenance to be transferred to the owner via a by-law.

    The implication of no by-law being put in place may well be that the owners corp remains responsible for the maintenance of those upgraded windows, as it is the by-law that transfers responsibility for such works to the owner.

    Note: I am not a lawyer, have just read the the act and regulations as an owner interested in this question.
