Browse Forums Building Standards; Getting It Right! 1 Jan 15, 2016 12:25 pm Part of the independent assessment report I received recently highlights that the builder should have used control joins in the ceiling of my home as the ceiling space is quite large in its entirety and allows no room to cater for movement (expansion/contraction). After researching what control joins actually are, I was a bit shocked to think that I've never seen them before in anyone else's homes. Has anyone else had this type of work done? It is in alignment with the Australian standards. Also, are there alternatives that can be considered as they are quite noticeable. Cheers.

However that is a bit of extra work. I'm sure if you use a gyprock saw and cut the plasterboard at an angle you'll be able to cut 99.9% of the ceiling sheet without removing those cornices ( been there, done that before ).
