This is the part nobody thinks about until a pendant comes down.
A ceiling rose on plasterboard isn't a fixing. Plasterboard is 10mm of compressed gypsum. It'll hold a light shade. It won't hold a solid brass or concrete pendant swinging off it for twenty years.
So the fixing goes into structure. Glenn gets into the ceiling cavity, finds the joist, and fixes there. If the joist isn't where the pendant needs to be, he puts a timber batten between joists and fixes to that. Either way the weight is on framing, not on the sheet.
Heavy fixtures need it more. Anything chunky, and especially a cluster of three or four on one plate, puts real load on that one point. Same goes for a long drop in a stairwell, where the fitting has leverage as well as weight.
Old ceilings are their own job. In a Queenslander with VJ boards, Glenn works from the roof space so there's no surface cable and no patching on a ceiling that can't be matched.
